Abstract
Description
Technical Field
[0001] This application relates to the field of auxiliary equipment technology for the production of micro vacuum pumps, and in particular to a positioning bracket for the production of micro vacuum pumps. Background Technology
[0002] In the production process of miniature vacuum pumps, precise positioning of the pump body is a key step to ensure the efficient completion of assembly, testing and other processes.
[0003] Currently, most companies in the industry use simple tooling fixtures to perform positioning operations. These tooling fixtures have obvious defects. On the one hand, their positioning method is singular, and they can only fix the pump body from a single direction or a limited angle. This makes it difficult to meet the demand for multi-directional stable clamping of micro vacuum pumps in complex production processes. When performing precision assembly or multi-angle testing, the pump body is prone to displacement, resulting in a decrease in production accuracy.
[0004] On the other hand, existing tooling fixtures generally lack a pre-positioning structure. When placing the pump body, operators cannot quickly place it in the ideal initial position and can only adjust it through repeated trial and error. This not only consumes a lot of time, but frequent movement may also scratch the surface of the pump body and affect product quality. Therefore, a positioning bracket for the production of miniature vacuum pumps is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a positioning bracket for the production of miniature vacuum pumps, so as to solve the problems mentioned in the background art.
[0006] The positioning bracket for manufacturing a miniature vacuum pump provided in this application adopts the following technical solution:
[0007] A positioning bracket for manufacturing a miniature vacuum pump includes a support frame and a pump body. The outer wall of the support frame is fixedly connected to an mounting plate by multiple fixing plates. The outer wall of the mounting plate is equipped with a positioning mechanism for quickly fixing the pump body.
[0008] The positioning mechanism includes two clamping plates and two positioning rods. The two clamping plates are located on the left and right outer walls of the pump body and are in contact with the outer walls of the pump body. The two positioning rods are located on the upper and lower outer walls of the pump body. The positioning rods are equipped with second sliders through an elastic connection mechanism. The outer walls of the clamping plates are fixedly connected to first sliders. The outer wall of the mounting plate opposite to the pump body is rotatably connected to a rectangular turntable through a rotating shaft. The outer walls of multiple ends of the rectangular turntable are rotatably connected to curved rods. The outer walls of the two first sliders and the two second sliders opposite to the pump body are all fixedly connected to moving blocks. The end of the curved rod away from the rectangular turntable is rotatably connected to the moving block.
[0009] Preferably, the outer wall of the mounting plate is provided with multiple sliding grooves, and the two second sliders are slidably connected to the two first sliders on the inner wall of the multiple sliding grooves.
[0010] Preferably, a cylinder is fixedly mounted on the outer wall of the mounting plate away from the pump body via a mounting bracket, and the output end of the cylinder is fixedly connected to the outer wall of one of the moving blocks.
[0011] Preferably, the elastic connection mechanism includes a connecting plate fixedly connected to the outer wall of the second slider, two slide rods slidably connected to the outer wall of the connecting plate, and a positioning rod fixedly connected to the ends of the two slide rods.
[0012] Preferably, a spring is sleeved on the outer wall of the slide rod, one end of the spring is fixedly connected to the outer wall of the connecting plate, and the other end is fixedly connected to the outer wall of the positioning rod.
[0013] In summary, this application includes the following beneficial technical effects:
[0014] 1. This utility model, by setting clamping plates on the left and right sides of the pump body and positioning rods on the upper and lower sides, can simultaneously clamp the pump body in four directions. Compared with the existing single-direction or limited-angle fixing methods, it can effectively prevent the pump body from shifting during complex production processes such as precision assembly and multi-angle testing. This all-round stable clamping can ensure that the pump body maintains accurate positioning in each production stage, thereby significantly improving the production accuracy of the micro vacuum pump and ensuring that the product quality meets high standards.
[0015] 2. This utility model utilizes the cooperation of a positioning rod and an elastic connecting mechanism. Before the pump body is clamped by the left and right side clamping plates, the positioning rod is pre-contacted with the upper and lower surfaces of the pump body by elastic force, quickly adjusting the pump body to the ideal initial position and completing the pre-positioning and centering operation. This design avoids the process of repeated trial and error adjustments by the operator, greatly saving working time and improving production efficiency. At the same time, it reduces the risk of surface scratches caused by frequent movement of the pump body, effectively improving the appearance quality and overall quality of the product and reducing the defect rate.

Detailed Implementation
[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0021] This application discloses a positioning bracket for the production of a miniature vacuum pump. (Refer to...) Figure 1-3 A positioning bracket for the production of a miniature vacuum pump includes a support frame 1 and a pump body 4. The support frame 1 serves as the basic support structure for the entire positioning bracket, and its outer wall is fixedly connected to the mounting plate 3 through multiple fixing plates 2, providing a stable mounting base for the subsequent positioning mechanism.
[0022] The positioning mechanism is the core component for quickly fixing the pump body 4. Two clamping plates 8 are located on the left and right outer walls of the pump body 4, which can directly fit against the side walls of the pump body 4 to clamp the pump body 4 laterally. Two positioning rods 12 are located on the upper and lower outer walls of the pump body 4, and the positioning rods 12 are connected to the second slider 7 through an elastic connection mechanism. Specifically, the elastic connection mechanism includes a connecting plate 9 fixedly connected to the outer wall of the second slider 7. Two sliding rods 10 are slidably connected to the outer wall of the connecting plate 9. The positioning rods 12 are fixedly connected to the ends of the two sliding rods 10. A spring 11 is sleeved on the outer wall of the sliding rods 10. One end of the spring 11 is fixedly connected to the outer wall of the connecting plate 9, and the other end is fixedly connected to the outer wall of the positioning rod 12. This elastic connection mechanism enables the positioning rods 12 to achieve elastic pre-positioning of the upper and lower sides of the pump body 4 through the compression and rebound of the spring 11 when subjected to external force.
[0023] A first slider 6 is fixedly connected to the outer wall of the clamping plate 8. A second slider 7 is slidably connected to the inner wall of a plurality of grooves 5 opened on the outer wall of the mounting plate 3. A rectangular turntable 15 is rotatably connected to the outer wall of the mounting plate 3 away from the pump body 4 via a rotating shaft. A crank rod 14 is rotatably connected to the outer wall of a plurality of ends of the rectangular turntable 15. A moving block 13 is fixedly connected to the outer wall of the two first sliders 6 and the two second sliders 7 away from the pump body 4. The end of the crank rod 14 away from the rectangular turntable 15 is rotatably connected to the moving block 13. At the same time, a cylinder 17 is fixedly installed on the outer wall of the mounting plate 3 away from the pump body 4 via a mounting bracket 16. The output end of the cylinder 17 is fixedly connected to the outer wall of one of the moving blocks 13.
[0024] In actual use, the pump body 4 is placed on the positioning bracket. At this time, the positioning rods 12 located on the upper and lower sides of the pump body 4, with the help of the elastic force of the springs 11 in the elastic connection mechanism, first contact the upper and lower surfaces of the pump body 4, perform preliminary position limitation and center alignment of the pump body 4, and complete the pre-positioning operation. Then, the cylinder 17 is started. The output end of the cylinder 17 pushes the moving block 13 connected to it to move. The moving block 13 drives the rectangular turntable 15 to rotate through the crank rod 14. The rectangular turntable 15 then drives the other three moving blocks 13 to move synchronously through the other crank rods 14. Driven by the moving blocks 13, the first slider 6 and the second slider 7 slide in the slide groove 5 respectively, thereby causing the clamping plate 8 and the positioning rod 12 to move towards the pump body 4 at the same time, and finally achieve a firm clamping of the pump body 4 in four directions. In this process, the existence of the elastic connection mechanism ensures that the positioning rod 12 can not only ensure the stable fixation of the pump body 4 when it is finally clamped, but also avoid damage to the pump body 4 due to excessive rigid clamping force.
[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
