Description

Technical Field

[0001] This utility model relates to the field of workpiece clamping technology, and in particular to a clamping mechanism for the top cover of a diaphragm pump. Background Technology

[0002] The top cover of a diaphragm pump is an important component of the pump body structure, such as... Figure 2 The diagram shows the structure of the diaphragm pump cover. During the manufacturing of the diaphragm pump cover, the cover 40 needs to be fixed, which is achieved by machining the cover body 42 using a machining module. Currently, traditional processes involve manually tightening screws to secure the cover 40, which is time-consuming and labor-intensive. Furthermore, the positioning holes 43 on the cover body 42 are of varying sizes, making it difficult to guarantee positioning accuracy. After replacing the cover, the tooling needs to be readjusted, thus reducing production efficiency. Utility Model Content

Each clamping assembly includes a lifting cylinder, a pressure plate disposed at the output end of the lifting cylinder, and two pressure blocks respectively disposed at both ends of the pressure plate. Each positioning assembly includes a positioning seat and two positioning blocks respectively disposed on both sides of the positioning seat. Two positioning grooves are respectively formed on the end face of each positioning block away from the base. A positioning post is movably disposed within each positioning groove. The end of the positioning post away from the bottom of the positioning groove protrudes from the positioning groove and is frustoconical in shape, with its cross-sectional radius gradually increasing towards the other end. A spring is disposed on one side of the positioning post, one end of which abuts against the bottom of the positioning groove, and the other end abuts against the positioning post.

[0016] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0017] like Figure 1The diagram shown is a structural schematic of the diaphragm pump cover clamping mechanism provided by this utility model. The diaphragm pump cover clamping mechanism includes a base 10, at least two clamping components 20 disposed on the base 10, and at least four positioning components 30 respectively disposed on both sides of two of the clamping components 20. It is conceivable that the diaphragm pump cover clamping mechanism also includes other functional modules, such as a drilling processing module, a power supply module, a screw module, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0018] Please refer to the following: Figures 2 to 4 It should be noted that the diaphragm pump cover clamping mechanism is used to clamp multiple covers 40 of the diaphragm pump to stabilize the covers 40, thereby cooperating with the processing module to perform drilling and other operations on the covers 40. Each cover 40 includes a connecting pipe 41 and two caps 42 respectively disposed at both ends of the connecting pipe 41. Each cap 42 has two positioning holes 43 spaced apart, and a through hole 44 is provided between the two positioning holes 43, communicating with the inner tube of the connecting pipe 41. The diaphragm pump cover clamping mechanism clamps the connecting pipe 41, thereby allowing the processing module to process the surfaces of the two caps 42 and the through hole 44.

[0019] The base 10 is used to support the various components so that they can be fitted together to clamp the multiple top covers 40.

[0020] The clamping assembly 20 includes a lifting cylinder 21, a pressure plate 22 disposed at the output end of the lifting cylinder 21, and two pressure blocks 23 disposed at both ends of the pressure plate 22.

[0021] The output direction of the lifting cylinder 21 is toward the side away from the base 10 and perpendicular to the plane of the base 10. The lifting cylinder 21 can drive the pressure plate 22 away from or toward the base 10.

[0022] Two positioning components 30 are respectively disposed on both sides of the lifting cylinder 21, and their arrangement direction is parallel to the length direction of the pressure plate 22. The output end of the lifting cylinder 21 is fixedly connected to the middle section of the pressure plate 22, and the two ends of the pressure plate 22 are fixedly disposed on the side facing the positioning components 30 and the pressure block 23. In this way, the lifting cylinder 21 can drive and move the two pressure blocks 23 away from or towards the two positioning components 30 on both sides, thereby cooperating with the positioning components 30 to release or press the upper cover 40.

[0023] The pressure block 23 is made of POM plastic, which prevents damage to the surface of the upper cover 40 when it is pressed on the upper cover 40. The side of the pressure block 23 facing the positioning component 30 is V-shaped to match the circumferential outer wall of the connecting pipe 41 and to perform a positioning function thereon.

[0024] The positioning component 30 includes a positioning base 31 and two positioning blocks 32 respectively disposed on both sides of the positioning base 31.

[0025] The positioning seat 31 and the pressure block 23 are arranged perpendicular to the plane of the base 10. The positioning seat 31 is V-shaped on the side facing the pressure block 23. Thus, when the upper cover 40 is placed on the positioning seat 31, the tube body of the connecting pipe 41 matches the V-shaped surface of the positioning seat 33, and the connecting pipe 41 is positioned by its own weight. Furthermore, the pressure block 23, driven by the lifting cylinder 21, moves closer to the upper cover 40 and presses the upper cover 40 onto the positioning seat 31, thereby stabilizing the position of the upper cover 40.

[0026] The height of the positioning block 32 corresponds to the height of the positioning seat 31. The positioning block 32 is U-shaped, with its notch facing away from the base 10. The ends of the two side walls opposite to the notch are respectively provided with a slope. In this way, the positioning block 32 supports the cover 42 on the connecting pipe 41, and the position of the notch on the positioning block 32 can avoid the arc part of the connecting pipe 41.

[0027] The positioning block 32 has a positioning groove 33 on its end face away from the base 10, corresponding to the two positioning holes 43 on the cover 42. A positioning post 34 is movably disposed in the positioning groove 33. The end of the positioning post 34 away from the bottom of the positioning groove 33 protrudes from the positioning groove 33 and is frustoconical in shape. The radius of its cross-section gradually increases towards the other end. When the cover 42 is placed on the positioning block 32, the positioning holes 43 are fitted onto the positioning post 34. Different sized positioning holes 43 are matched by the frustoconical end of the positioning post 34, thereby improving the adaptability of the diaphragm pump cover clamping mechanism.

[0028] A spring 35 is provided on one side of the positioning post 34. One end of the spring 35 abuts against the bottom of the positioning groove 33, and the other end abuts against the positioning post 34. Thus, when the cover 42 is placed on the positioning block 32, the cover 42 presses against the positioning post 34 and compresses the spring 35, so that the positioning post 34 can be reset when the upper cover 40 is removed.

[0029] The positioning post 34 has a first step 36 in the middle section, and the positioning groove 33 has a second step 37 near its opening. When the spring 35 rebounds and orients the positioning post 34 toward the opening of the positioning groove 33, the first step 36 and the second step 37 abut against each other, thereby limiting the positioning post 34 in the positioning groove 33.

[0030] Compared with the prior art, the diaphragm pump cover clamping mechanism provided by this utility model uses the lifting cylinder 21 to drive the two pressure blocks 23 to press the cover 40 onto the positioning seat 31. The two cover bodies 42 at both ends of the cover 40 are supported by the two positioning blocks 32, thus stabilizing the cover 40 and facilitating the processing module to process the surfaces of the two cover bodies 42 and the through holes 44. Furthermore, the frustum-shaped end of the positioning post 34 can match positioning holes 43 of different sizes, thereby improving the adaptability of the diaphragm pump cover clamping mechanism. The diaphragm pump cover clamping mechanism can press the two covers 40 together with the positioning assembly 30 using only one lifting cylinder 21, greatly improving production efficiency.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
