Description

A device for grinding burrs on corners of nonferrous metal castings

Technical Field

The utility model relates to the technical field of metal casting edge corner deburring devices, in particular to a non-ferrous metal casting edge corner burr grinding device.

Background Art

Nonferrous metals, in a narrow sense, are also called non-ferrous metals. They are a general term for all metals other than iron, manganese and chromium. Nonferrous metals in a broad sense also include nonferrous alloys. Nonferrous metal castings are metal parts made of nonferrous metals or nonferrous alloys, of which pipe nonferrous metal castings are one type.

After the non-ferrous metal tubes are cut, some metal tubes are soft and easy to deform, such as copper tubes or aluminum tubes, which may easily produce burrs on the edges and corners of the metal tubes after cutting. They may need to be polished to meet the needs of use. At this time, the operator usually uses manual sandpaper to polish, which is time-consuming and labor-intensive. In the process of using sandpaper to polish, the outer surface of the metal tube at other positions may be over-polished or damaged, affecting the later use of the metal tube.

DETAILED DESCRIPTION

The utility model is further described in detail below in conjunction with the accompanying drawings.

Example

Referring to Figs. 1-3, the utility model discloses a device for grinding burrs on the corners of non-ferrous metal castings, comprising a grinding plate 1 and a plurality of grinding blocks 2 for grinding non-ferrous metal pipe castings, the grinding block 2 being cylindrical, and the plurality of grinding blocks 2 being relatively arranged on the bottom side of the grinding plate 1, a connecting mechanism 3 being provided in the grinding block 2 and at the top of the grinding plate 1, and the connecting mechanism 3 is used to connect the grinding plate 1 with the grinding block 2 and between the grinding plate 1 and the hand drill. The connecting mechanism 3 comprises a support plate 31, a connecting rod 32 is fixedly installed at the middle position of the top of the support plate 31, a plurality of threaded rods 33 are relatively arranged on the bottom side of the support plate 31, a circular hole 34 is provided at the center position of the grinding block 2, a limiting hole 35 is provided at the position corresponding to the circular hole 34 in the grinding plate 1, the threaded rod 33 is penetrated in the corresponding circular hole 34 and the corresponding limiting hole 35, and the outer peripheral wall of the threaded rod 33 is connected with the inner wall of the corresponding limiting hole 35 and the inner wall of the corresponding circular hole 34. The mutual interference between the threaded rod 33 and the inner wall of the circular hole 34 and the inner wall of the limiting hole 35 can constrain and limit the grinding block 2 and the grinding plate 1, so that the friction between the non-ferrous metal pipe casting and the grinding block 2 and the grinding plate 1 will drive the relative displacement between the grinding plate 1 and the support plate 31.

The bottom end of the grinding block 2 is provided with a support mechanism 4, and the support mechanism 4 supports and limits the nonferrous metal tube casting of the grinding block 2. The support mechanism 4 includes an inner tube 41, which is sleeved on the outer peripheral side of the corresponding threaded shaft, and the inner tube 41 is located below the corresponding grinding block 2. The inner tube 41 is made of metal materials such as titanium alloy or hard alloy. The outer peripheral side of the inner tube 41 is rotatably sleeved with a support ring 42 through a bearing, and the cross-section of the support ring 42 is semicircular. The support ring 42 is made of hard materials such as hard plastic or plastic. A soft ring 43 is fixedly penetrated on the opposite surface of the inner tube 41 and the grinding block 2, and the soft ring 43 is sleeved on the outer peripheral side of the corresponding threaded rod 33. The soft ring 43 is a rubber ring. The bottom end of the threaded rod 33 is threadedly sleeved with a nut 36, and the nut 36 is located at the lower end of the corresponding inner tube 41. The setting of the inner tube 41 can enhance the strength of the inner ring wall of the support ring 42, and enable the nut 36 to stably push the grinding block 2 toward the support plate 31. The setting of the support ring 42 ensures that the constraint limit of the grinding block 2 will not affect the rotation of the support ring 42, thereby preventing relative displacement between the support ring 42 and the non-ferrous metal casting. The setting of the soft ring 43 makes the inner tube 41 and some parts of the grinding block 2 rougher, thereby enhancing the friction between the grinding block 2 and the inner tube 41, and ensuring that there is always a certain gap between the support ring 42 and the grinding block 2.

The implementation principle of the above embodiment is as follows: when grinding the burrs on the corners of the non-ferrous metal pipe casting, first, the connecting rod 32 is inserted into the mounting end of the hand drill, and the connecting rod 32 is clamped and fixed on the mounting end of the hand drill by the hand drill clamp, and finally the support plate 31 is constrained and limited at the output end of the hand drill by pulling the connecting rod 32, and then the operator holds the hand drill to move the support plate 31 to move the grinding plate 1 to the end of the non-ferrous metal pipe casting, and makes the connecting rod 32 located at the center position of the end of the non-ferrous metal pipe casting, and then moves the non-ferrous metal pipe casting so that the pipe wall of the non-ferrous metal pipe casting is inserted between the corresponding two grinding blocks 2, and then starts the hand drill to drive the support plate 31 to rotate, and due to the mutual interference between the threaded rod 33 and the inner wall of the circular hole 34 and the inner wall of the limiting hole 35, the support plate 31 and the grinding block 2 rotate synchronously, and the support plate 31 and the grinding block 2 rotate around the corners of the colored metal pipe casting in an intermediate state, thereby erasing the burrs on the corners of the colored metal pipe casting;

It should be noted that when the grinding plate 1 rotates, the mutual interference between the plurality of support rings 42 and the inner arc wall and the outer arc wall of the non-ferrous metal pipe casting can constrain and limit the grinding plate 1 and the grinding block 2, so that the spacing between the edge corner of the non-ferrous metal pipe casting and the grinding block 2 and the grinding plate 1 will hardly change, so that the grinding plate 1 and the grinding block 2 will only grind the burrs at the edge corners of the non-ferrous metal pipe casting;

When replacing the grinding block 2 or the grinding plate 1, firstly, the nut 36 is rotated in the opposite direction to reduce the resistance between the grinding block 2 and the support tube and the grinding plate 1. At this time, the grinding block 2 can be rotated to adjust the grinding position of the grinding block 2, which can extend the service life of the grinding block 2. After the nut 36 is removed from the threaded rod 33, the support tube is removed from the threaded tube, and then the grinding block 2 is removed from the threaded rod 33, and a new grinding block 2 is replaced and sleeved on the threaded rod 33, and the inner tube 41 is re-sleeved on the threaded rod 33. Finally, the nut 36 is screwed onto the threaded rod 33 again, and the grinding block 2 is pushed toward the grinding plate 1. At this time, the two soft rings 43 are deformed by contacting each other, increasing the contact area of the two soft rings 43 and generating a great friction force. At the same time, an isolation support structure is formed between the inner tube 41 and the grinding block 2, so that there is always a certain gap between the grinding block 2 and the support ring 42. The rough surface of the grinding block 2 and the grinding plate 1 also contact each other to generate a great friction force, thereby locking the position of the grinding block 2.

According to the above, all the grinding blocks 2 are removed from the threaded rod 33 to release the constraint of the grinding plate 1. At this time, the grinding plate 1 can be removed from the threaded rod 33, and a new grinding plate 1 can be replaced and installed under the support plate 31. Finally, according to the above, the installation of the grinding blocks 2 can be removed to complete the replacement of the grinding plate 1.

The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
