Please refer to Fig. 1, shown in 2, the moving mechanism of carrying grinder proposed by the utility model is provided with a base 10, and a guide member and a moving device 20 are arranged on the top of the base 10, and the moving device 20 is driven by a The parts drive the belt sander 30 to move along the guide member. The front side of the belt sander 30 is provided with a workpiece fixing device 40 to place the workpiece 41 horizontally on the sand belt of the belt sander 30. On the front side, when the workpiece fixing device 40 drives the workpiece 41 to rotate, the abrasive belt grinder 30 is displaced along the axial direction of the workpiece 41 to grind the surface of the workpiece 41, and when the workpiece 41 is a curved pipe, its radius of gyration The pressure applied to the abrasive belt is also different. At this time, the abrasive belt grinder 30 can automatically move along the radial direction of the workpiece 41, so that the abrasive belt can maintain a certain tension, so as to achieve automatic grinding and uniform grinding quality. the goal of.

In addition, a group of mobile devices 50 and a group of different types of grinders are added on the top surface of the base 10. In this preferred embodiment, a cloth wheel grinder 60 is provided to match the smaller curvature of the grinding workpiece 41. fold.

The above is an overview of the functions of the present utility model, and its detailed components and actuation methods are described as follows:

Please refer again to Figs. 1 and 2, two guide rods 11 parallel to the axial direction of the workpiece 41 are arranged on the top of the base 10, and the moving device 20 includes a motor 21 positioned on the top surface of the base 10, A moving seat 22 that is placed on the two guide rods 11 and is provided with a belt sander 30 on the top, two rotating wheels 23 that are adjacent to the two ends of the guide rod 11, and two rotating wheels 23 that are wound around the two guide rods 11 The chain 24, the two ends of the chain 24 are respectively fixed on the moving seat 22, one of the rotating wheels 23 is driven by the motor 21 to rotate, so that the chain 24 drives the moving seat 22 together with the belt sander 30 to move along the guide bar 11 .

The above is the case of setting a single grinder, if a second grinder (such as a cloth wheel grinder 60) is set, the motor 51 of another group of moving devices 50 is required to drive a rotating wheel 52, and then by The chain 53 wound around the rotating wheel 52 drives a moving seat 54 that is placed on the two guide rods 11 to displace, and the cloth wheel polisher 60 is located on the moving seat 54 .

The driving parts of the aforementioned moving devices 20, 50 can also be set as cylinders, and the cylinder shafts are used to move the moving devices to be displaced on the guide rods or other guiding structures.

In order to enable the grinder to automatically displace during the grinding overshift, and to apply appropriate pressure to the workpiece 41, a pushing device 70 is provided between the bottom of the grinder and the moving seats 22, 54. For the convenience of explanation, the following The moving device 70 located between the cloth wheel grinder 60 and the moving seat 54 is taken as an example for illustration, and the structure of the moving device 70 located below the belt sander 30 is also the same, so it will not be described in detail.

Please refer to FIG. 3 , the pushing device 70 includes a positioning seat 71 that can slide on the top of the moving seat 54, a first cylinder 72 that is located on the moving seat 54 and drives the displacement of the positioning seat 71, and a first cylinder 72 that is located on the positioning seat. 71 on the seat 73, a second press cylinder 74 which is arranged on the seat 73 and can drive the displacement of the cloth wheel polisher 60, wherein the bottom of the cloth wheel polisher 60 is combined with the second press cylinder 74 On the cylinder shaft, two sets of slide rails 61 and slide grooves 731 that can be fitted with each other are provided at intervals between the bottom of the cloth wheel grinder 60 and the top of the bearing seat 73. Vertically, when the cloth wheel grinder 60 grinds the side and is pushed by force, even if the cylinder shaft of the second cylinder 74 is retracted, when the thrust given to the cloth wheel grinder 60 is released, the second The pressure of the press cylinder 74 pushes out the press cylinder shaft together with the cloth wheel polisher 60, and combines a base block 75 at the bottom of the bearing seat 73. The base block 75 is arranged on the positioning seat 71, and the positioning seat 71 is provided with two A parallel guide rod 711 and a lead screw 712 between the two guide rods 711, the axial direction of the guide rod 711 and the lead screw 712 is perpendicular to the guide rod 11, the base block 75 at the bottom of the seat 73 is located On the two guide rods 711, the lead screw rod 712 is threaded. When the lead screw rod 712 is rotated, the base block 75, the seat 73 and the cloth wheel grinder 60 will axially displace along the guide rod 711. Between the bottom of the positioning seat 71 and the top surface of the moving seat 54, two groups of slide rails 713 and chute 541 are provided, which are fitted with each other. The axial directions of the shafts are all perpendicular to the guide rod 11, and the cylinder shaft of the first cylinder 72 is also combined with the bottom surface of the positioning seat 71. Therefore, the positioning seat 71 together with the bearing seat 73 and the distribution seat 71 can be driven by the first cylinder 72. The wheel grinder 60 is displaced together.

Please refer to shown in Fig. 4, above-mentioned is the structure of the moving seat 20 of the utility model at the bottom of the cloth wheel grinder 60 (the structure of the pushing device 70 at the bottom of the belt grinder 30 is also the same), and it is first started before grinding. The first pressure cylinder 72 moves the grinding surface of the cloth wheel polisher 60 to the side of the workpiece 41, and then gives constant pressure. If the position is not ideal, the lead screw 712 is used to fine-tune the cloth wheel polisher 60. Optimum grinding position, that is, the cloth wheel grinder 60 and the workpiece fixing device 40 shown in Figure 1 can be started, and the motors 21, 51 on the moving devices 20, 50, so that the grinder can be moved along the axis of the workpiece 41 in rotation. When the workpiece 41 is a curved pipe or non-circular pipe and the radius of gyration is changed, different pressures will be applied to the cloth wheel sander 60 and the belt sander 30, forcing the sander to move forward. A certain pressure on the workpiece 41 maintains a uniform grinding effect.

It can be seen from the above that the utility model can provide a polishing unit that grinds along the axial direction of the workpiece and can maintain a fixed pressure on the workpiece on the grinding surface, thereby overcoming the defects of the prior art and achieving automatic grinding and uniform grinding quality the goal of.

Although the utility model has been disclosed with preferred embodiments, it is not intended to limit the utility model. Any person skilled in the art can replace equivalent components without departing from the concept and scope of the utility model, or The equivalent changes and modifications made according to the scope of protection of the utility model patent should still fall within the category covered by this patent.
