At that time, the problem of low quality of the finished product will appear. Therefore, we have made improvements to this and proposed a jig circulation mechanism. Utility Model Content

[0024] Specific reference Figure 1 , Figure 2 A driving assembly 2 is fixedly provided on the side of the first slide 4 away from the linear slide rail 1, a positioning mechanism 3 is fixedly provided on the side of the second slide 5 away from the linear slide rail 1, and a transport assembly 13 for transporting the part body 16 is fixedly provided at both ends of the linear slide rail 1.

[0025] Specific reference Figure 1 , Figure 4The driving assembly 2 includes a first guide rail 204, a servo motor 201 is fixedly installed at one end of the first guide rail 204, a first slider 202 is slidably arranged on the first guide rail 204, a fixed block 203 is fixedly connected to one side of the first slider 202, the fixed block 203 is fixedly connected to the first slider 4, the positioning mechanism 3 includes a three-axis cylinder 301, a connecting rod 302 is fixedly connected to the output end of the three-axis cylinder 301, a connecting block 303 is fixedly installed at one end of the connecting rod 302, and the connecting block 303 is fixedly installed on the second slide rail 1304.

[0026] It should be noted that, by setting up a servo motor 201, the first slider 202 is driven to slide on the surface of the first guide rail 204, and then the first slider 4 fixedly connected to the fixed block 203 is driven to slide on the first slide rail 6. By starting the three-axis cylinder 301, the connecting rod 302 is driven to move toward the direction close to the part body 16, and then the second slider 5 fixedly connected to the fixed block 203 is driven to move toward the direction close to the part body 16 until one side of the part body 16 is pressed tightly to achieve the positioning effect. At this time, the second slider 5 drives the third slider 15 to slide on the track of the third slide rail 14.

[0027] Specific reference Figure 1 , Figure 5 The transport component 13 includes a second guide rail 1305, a motor 1301 is fixedly installed at one end of the second guide rail 1305, a second slider 1302 is slidably arranged at one end of the second guide rail 1305 away from the motor 1301, the upper surface of the second slider 1302 is fixedly connected to the bottom plate 1303, and the upper surface of the bottom plate 1303 is fixedly arranged with a second slide rail 1304.

[0028] In the specific setting, when the part body 16 slides from one end of the linear guide rail 1 to the second guide rail 1304 under the drive of the positioning mechanism 3, the motor 1301 is started to drive the second slider 1302 to slide on the second guide rail 1305, and then the bottom plate 1303 on the second slider 1302 slides along one end of the second guide rail 1305 to the other end, and then the part body 16 is transported to the other end of the second guide rail 1305, and then the bottom plate 1303 is aligned with the linear guide rail 1, and the part body 16 is driven by the positioning mechanism 3 and the driving component 2 on the other side. The body 16 slides on the linear slide 1 on the other side. After the part body 16 is processed, it is transported to the transport assembly 13 at the other end through the positioning mechanism 3 and the driving assembly 2 on the other side. This completes a cycle of processing for the part body 16. In this process, a high-precision servo motor 201 is used to drive the slide rail slider to move in a straight line. In addition to the servo movement memory, a positioning mechanism 3 is added for secondary positioning each time it moves. This ensures that there is no cumulative error in the movement of the fixture and reduces the defective rate of parts after processing.

[0029] Specific reference Figure 1 , Figure 3 A cylinder 12 is fixedly mounted on the lower surface of the linear guide rail 1 , and a mounting block 17 for rotating the positioning rod 8 is fixedly connected to the cylinder 12 .

[0032] When in use, first place the part body 16 on the second slide rail 1304, start the motor 1301 to drive the part body 16 to slide to the end of the second guide rail 1305, until the bottom plate 1303 is aligned with the linear slide rail 1, start the servo motor 201 to drive the first slide plate 4 fixed to the first slider 202 to slide on the first slide rail 6 in the direction close to the part body 16, then start the three-axis cylinder 301 to drive the second slide plate 5 along the track of the third slide rail 14 to approach the part body 16, until one side of the part body 16 is pressed against to play a positioning role, at this time, by starting the cylinder 12 It drives the mounting block 17 to move, and then drives the positioning block 10 to move toward the direction close to the part body 16 until the other side of the part body 16 is pressed tightly to achieve secondary positioning. Then the servo motor 201 is started to drive the first slide 4 to return. At this time, the part body 16 is driven by the second slide 5 to slide from one end of the linear slide 1 to the other end until it slides onto the bottom plate 1303 at the other end. Then the motor 1301 at the other end is started to drive the part body 16 to slide onto the linear slide 1 on the other side.
