Detailed ways

The implementation of the utility model will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the implementation process of how to apply technical means to solve technical problems and achieve technical effects in the utility model. It should be noted that, as long as there is no conflict, each embodiment and each feature in each embodiment of the utility model can be combined with each other, and the formed technical solutions are all within the protection scope of the utility model.

Specifically, as shown in Figure 1-3, the existing technologies have the following problems:

1. The T-nut is inconvenient to disassemble. Because there is no round countersunk hole on the workbench of most equipment, the T-nut can only be inserted from both ends of the workbench; it is not easy to operate during the clamping process, and it is difficult for the T-nut to move left and right in the T-shaped slot on the workbench , can only be moved by sliding, and the installation process is time-consuming and labor-intensive.

2. The upper step surface of the T-nut is easy to wear during use. After several times of continuous clamping of the workpiece, the surface in contact with the workbench is easy to wear, resulting in the wear of the upper step surface of the T-nut, and there is no gripping force during use, so it is easy to appear under the condition of excessive force. Slip, causing the T-nut to be scrapped, and the waste is very serious.

3. T-type nuts are prone to slipping during tightening and use with stud bolts, and often need to return the thread (pass the thread on the stud bolt with a die), which leads to too long auxiliary time for the workpiece during processing, and the T-type The nut is easy to slip, the wire is easy to pull off, it is inconvenient to operate, the workpiece is not easy to be compressed, and the compressed state of the workpiece is difficult to ensure. If it is not possible to ensure that the workpiece and the workbench are in a compressed state during processing, it will lead to excessive resistance of the workpiece during processing, resulting in out-of-tolerance processing dimensions and deformation of the workpiece, which may cause quality and safety accidents and affect the normal use of the workpiece. performance.

For this reason, as shown in Figure 4-6, the utility model is to overcome the above-mentioned deficiencies in the prior art, in order to solve the difficult problem that the workpiece is in a reliable compacted state on the workbench, a set of new design of compacted rhombus seat is proposed plan. It can ensure the stability of connecting the T-slot of the workbench and the workpiece, and improve the production efficiency. The device has the advantages of simple structure, wide application range, convenient operation and convenient popularization and use.

Among them, a diamond-shaped seat for pressing the workbench of a machine tool, including: a nut (1), a stud bolt (2), a workbench (3), a pressure plate (4), a spacer (5) and a shoulder nut (6) , wherein the nut (1) is a T-shaped nut with a through hole in the middle for matching with the bolt, and is installed in the T-shaped slot on the machine table to fix the position of the bolt, and the nut (1) is installed in a double-headed One end of the bolt (2), the stud bolt has external threads at both ends, and the stud bolt is loaded from both ends of the T-shaped slot on the workbench (3). In addition, the workbench (3) is set There is a spacer (5), which is a group of four equal-height spacers, and is arranged between the pressure plate (4) and the bolt and the pressing part; the spacer (5) is equipped with all Press the plate (4) above, and press it with the shoulder nut (6).

How to use: According to the difference in the height and width of different workpieces, the height of the spacer can be increased or decreased to meet the compaction requirements. At the same time, the lengthening nut can be used to increase the height of the screw on the rhombus seat. The width direction can be controlled by the T-shaped groove on the workbench. Adjust the quantity before and after, put the compression diamond seat vertically into the T-shaped slot in the workbench, turn it counterclockwise 90°, after the compression position is determined, install the spacer, connect the fuselage with the pressure plate and use the shoulder nut Press tight. See Figure 5 for the usage of the new compression diamond seat.

Wherein, since the new compression diamond seat is a whole, put the diamond seat vertically into the T-shaped slot in the workbench, and after turning it counterclockwise 90°, the two sides are close to the two sides of the upper T-slot on the workbench. The diamond-shaped seat can rotate 90° left and right in the T-shaped slot on the workbench 2, and the degree of freedom is not limited. The diamond-shaped seat is perpendicular to the worktable surface. After the pressing position of the fuselage is determined, install the spacer and connect the fuselage with a pressure plate. Use the shoulder nut to compress, and ensure that the diamond seat is perpendicular to the bottom surface of the T-shaped groove on the workbench during the pressing process, and rotate 360° clockwise when pressing, so that the diamond-shaped seat cannot move in the T-shaped groove, and the diamond-shaped seat The reverse chamfer on the top will increase the grip force and also play a self-locking function. Use the same method to compress the other three places through the same working principle. The pressing mechanism has a self-locking function, and the diamond-shaped seat 1 will not be disengaged from the pressing mechanism during the processing, and the processing process is stable.

Processing with the new diamond-shaped seat for pressing is mainly convenient for disassembly and operation, and saves time and effort when pressing the workpiece; at the same time, the design of the new diamond-shaped seat for pressing prevents the two parts from being together for a long time. The wires slipped due to dismantling over time, and the wires often regressed, resulting in undurability; and a reverse chamfer was designed to improve the durability of the new compression rhombus seat. During the use process, the processing quality and processing accuracy of the workpiece are improved, and the production efficiency is also improved to ensure the performance of the parts.

Key technology of the utility model:

1. The design of the new compression rhombus seat as a whole meets the requirements of on-site use.

2. When manufacturing the new type of diamond seat for compression, it requires one-time processing and forming, and then heat treatment.

That is, the manufacturing accuracy is guaranteed, and the manufacturing difficulty and cost are reduced.

3. The new compression rhombus seat is designed with reverse chamfers to prolong the service life and improve the durability.

4. The new clamping diamond-shaped seat is designed with reverse chamfers, which reduces the contact area with the T-slot of the machine tool and increases the friction force, making the workpiece tightening stable and firm.

Through on-site practice and popularization, the diesel engine body, crankshaft and small and medium-sized parts compacted before processing by using this new compacting diamond seat compaction method all meet the processing requirements and are easy to disassemble. The processing efficiency is improved, the auxiliary time is shortened, and it is relatively durable. The use stability is good, which ensures the processing quality, processing accuracy and performance of the parts.

It has been tested in practice that this new compression mechanism with a rhombus seat has the advantages of simple structure, wide application range, convenient operation, low production cost, and easy popularization and use. At present, this processing method has been applied to many equipments.

Finally, it should be noted that: the above is only a preferred embodiment of the utility model, and is not intended to limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art , it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
