[0002] In modern industrial production, fixtures are indispensable tools used to fix workpieces during processing or assembly to ensure processing accuracy and production efficiency. Traditional fixture systems usually use cylinders as driving elements, and use air pressure to control the expansion and contraction of the cylinder to achieve workpiece positioning and clamping.

[0003] However, there are some limitations to pneumatic cylinder-driven fixtures. The cost of the cylinder is relatively high, especially in production lines that require a large number of fixtures. Secondly, the cylinder system requires regular maintenance, such as checking seals and cleaning pipes, to ensure its normal operation. Utility Model Content

[0004] In view of this, the utility model provides a side processing pressing mechanism which can reduce costs to meet industrial needs.

[0005] A side processing pressing mechanism includes a positioning fixture, at least one processing station arranged on the positioning fixture, and a pressing unit arranged on the positioning fixture, each of the pressing units includes a driving device arranged on the positioning fixture, and a constant pressure device arranged on the driving device. The driving device includes a driving body arranged on the positioning fixture, a rotating member arranged on the driving body, and a sliding groove arranged on the side wall of the rotating member. The sliding groove includes a lifting section arranged along the axial direction of the rotating member, and a sliding section inclined on the side wall of the rotating member. The two ends of the sliding section are respectively connected to the two end ends of the lifting section. The constant pressure device includes a constant pressure sleeve sleeved on the rotating member, a sliding rod arranged on the constant pressure sleeve, a reset spring accommodated between the constant pressure sleeve and the rotating member, and an abutting end head arranged on the free end of the constant pressure sleeve. The sliding rod is inserted into the sliding groove. When the side processing pressing mechanism processes the workpiece, the driving body drives the rotating member to rotate, and the sliding rod in the fixed pressure device slides along the sliding groove to adjust the position of the fixed pressure device.

[0006] Furthermore, the inner diameter of the constant pressure sleeve body is the same as the outer diameter of the rotating member.

[0007] Furthermore, the constant pressure sleeve includes a constant pressure sleeve body and a mounting groove arranged at a free end of the constant pressure sleeve body.

[0008] Furthermore, the outer contour of the abutting end head is hexagonal.

[0009] Furthermore, one end of the return spring abuts against one end of the constant pressure sleeve body, and one end of the return spring abuts against one end of the rotating member.

[0010] Furthermore, the driving device is a motor.

Each of the pressing units includes a driving device arranged on the positioning fixture, and a constant pressure device arranged on the driving device. The driving device drives the constant pressure device to lift and press. The driving body in the driving device drives the rotating part to rotate, and a sliding groove is arranged on the side wall of the rotating part. A sliding rod, a return spring accommodated in the constant pressure sleeve, and an abutting top head arranged on the free end of the constant pressure sleeve are arranged on the constant pressure sleeve of the constant pressure device. When the sliding rod slides along the sliding section, the sliding rod drives the height of the constant pressure sleeve body to change, and the bottom end of the lifting section slides to the top end of the lifting section. When the sliding rod slides to the lifting section, since the lifting section is arranged along the axial direction of the rotating part, the sliding rod enters the lifting section, and the sliding rod slides from the top end of the lifting section to the bottom end of the lifting section. The reset spring uses its own elastic force to reset the constant pressure sleeve. The reset of the constant pressure device is to press against the workpiece on the processing station to limit the position of the workpiece. It can be seen from this that the side processing pressing mechanism has a simple structure, convenient operation, low manufacturing cost, and convenient maintenance.

[0015] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0016] like Figures 1 to 3As shown, it is a schematic diagram of the structure of the side processing pressing mechanism provided by the utility model. The side processing pressing mechanism includes a positioning fixture 1, at least one processing station 2 arranged on the positioning fixture 1, and at least one pressing unit 10 arranged on the positioning fixture 1. The side processing pressing mechanism also includes some other functional modules, such as assembly components, etc., which should be technologies well known to those skilled in the art and will not be described in detail one by one here.

[0017] The positioning fixture 1 is used to fix the workpiece during the production process, and the processing station 2 is used to accommodate the workpiece to be processed. The positioning fixture 1 and the processing station 2 are a prior art and will not be described in detail here.

[0018] Each of the pressing units 10 includes a driving device 11 disposed on the positioning fixture 1, and a constant pressure device 12 disposed on the driving device 11. Each of the pressing units 10 corresponds to a processing station 2, so that the pressing unit 10 can limit the workpiece to be processed to the processing station 2.

[0019] The driving device 11 includes a driving body 111 disposed on the positioning fixture 11, a rotating member 112 disposed on the driving body 111, and a sliding groove 113 disposed on the side wall of the rotating member 112. The rotating member 112 is disposed at the output end of the driving body 111, thereby driving the rotating member 112 to rotate. The driving device 11 is a motor, which is a prior art and will not be described in detail here.

[0020] The sliding groove 113 includes a lifting section 1131 arranged along the axial direction of the rotating member 112, and a sliding section 1132 arranged obliquely on the side wall of the rotating member 112. The two ends of the sliding section 1132 are respectively connected to the two end ends of the lifting section 1131, so that the sliding section 1132 and the lifting section 1131 form a whole. The sliding groove 113 cooperates with the constant pressure sleeve 121, so the sliding groove 113 will be described in detail in conjunction with the constant pressure sleeve 121, and will not be repeated here.

[0021] The constant pressure device 12 includes a constant pressure sleeve 121 sleeved on the rotating member, a sliding rod 122 arranged on the constant pressure sleeve 121, a return spring 123 accommodated between the constant pressure sleeve 121 and the rotating member, and an abutting end head 124 arranged on the free end head of the constant pressure sleeve 121.

[0022] The constant pressure sleeve 121 includes a constant pressure sleeve body 1211 and a mounting groove 1212 arranged at a free end of the constant pressure sleeve body 1211 .

[0023] The inner diameter of the constant-pressure sleeve body 1211 is the same as the outer diameter of the rotating member 112 , so that the position of the rotating member 112 inserted into the constant-pressure sleeve body 1211 is stable.

[0024] The mounting groove 1212 is used to accommodate the abutting top head 124 , so that the abutting top head 124 can be installed on the free end of the constant pressure sleeve 121 , thereby realizing quick installation of the abutting top head 124 .

[0025] The sliding rod 122 is inserted into the sliding groove 113. When the sliding rod 122 slides along the rotating member 112, the position of the constant pressure sleeve body 1211 is lifted and lowered. When the sliding rod 122 slides along the sliding section 1132, since the sliding section 1132 is tilted on the side wall of the rotating member 112, that is, during the sliding process, the sliding rod 122 drives the constant pressure sleeve body 1211 to change in height, sliding from the bottom end of the lifting section 1131 to the top end of the lifting section 1131. When the sliding rod 122 slides to the lifting section 1131, since the lifting section 1131 is axially arranged along the rotating member 112, the sliding rod 122 enters the lifting section 1131, and the sliding rod 122 slides from the top end of the lifting section 1131 to the bottom end of the lifting section 1131, thereby achieving the pressing of the constant pressure sleeve 121.

[0026] One end of the return spring 123 abuts against one end of the constant pressure sleeve body 1211 , and one end of the return spring 123 abuts against one end of the rotating member 112 , so that the return spring 123 automatically resets the constant pressure sleeve body 1211 through its own elastic force.

[0027] The outer contour of the abutting head 124 is consistent with the shape of the positioning groove of the workpiece to be processed, so that the abutting head 124 can be inserted into the positioning groove of the workpiece to be processed, thereby stably limiting the workpiece to be processed. In this embodiment, the outer contour of the abutting head 124 is hexagonal.

[0028] When the side processing pressing mechanism processes the workpiece, the driving body 111 drives the rotating member 112 to rotate. As the rotating member 112 rotates, the sliding rod 122 in the constant pressure device 12 slides along the sliding groove 113 to adjust the position of the constant pressure device 12. When the sliding rod 122 slides along the sliding section 1132, the sliding rod 122 drives the constant pressure sleeve body 1211 to change in height, sliding from the bottom end of the lifting section 1131 to the top end of the lifting section 1131, and the return spring 123 is compressed in the process. When the sliding rod 122 slides to the lifting section 1131, since the lifting section 1131 is axially arranged along the rotating part 112, the sliding rod 122 enters the lifting section 1131, and the sliding rod 122 slides from the top end of the lifting section 1131 to the bottom end of the lifting section 1131. The reset spring 123 uses its own elastic force to reset the constant pressure sleeve 121, thereby realizing the pressing work of the constant pressure device 12.

[0029] Compared with the prior art, the side processing pressing mechanism provided by the utility model limits the position of the workpiece at the processing station 2 through the pressing unit 10. Each of the pressing units 10 includes a driving device 11 arranged on the positioning fixture 1, and a constant pressure device 12 arranged on the driving device 11. The driving device 11 drives the constant pressure device 12 to lift and press. The driving body 111 in the driving device 11 drives the rotating member 112 to rotate, and a sliding groove 113 is arranged on the side wall of the rotating member 112. A sliding rod 122 is arranged on the constant pressure sleeve 121 of the constant pressure device 12, a return spring 123 accommodated in the constant pressure sleeve 121, and an abutment tip 124 arranged on the free end of the constant pressure sleeve 121. When the sliding rod 122 slides along the sliding section 1132, the sliding rod 122 drives the height of the constant-pressure sleeve body 1211 to change, and the bottom end of the lifting section 1131 slides to the top end of the lifting section 1131. When the sliding rod 122 slides to the lifting section 1131, since the lifting section 1131 is axially arranged along the rotating member 112, the sliding rod 122 enters the lifting section 1131, and the sliding rod 122 slides from the top end of the lifting section 1131 to the bottom end of the lifting section 1131. The reset spring 123 uses its own elastic force to reset the constant-pressure sleeve 121. The reset of the constant-pressure device 121 is to press against the workpiece on the processing station 2 to limit the position of the workpiece. It can be seen from this that the side processing pressing mechanism has a simple structure, convenient operation, low manufacturing cost, and convenient maintenance.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
