Description

Technical Field

[0001] This utility model relates to the field of diaphragm pump processing technology, and in particular to a fixture for a diaphragm pump elbow. Background Technology

[0002] Diaphragm pumps, also known as control pumps, are a major type of actuator. They change the fluid flow rate by receiving control signals from the regulating control unit and using power. They are a new type of conveying machinery that can transport various corrosive liquids, liquids containing particles, and high-viscosity, volatile, flammable, and highly toxic liquids.

[0003] The elbow of a diaphragm pump is an important component in the pump's structure. It connects the diaphragm chambers on both sides of the pump, thereby enabling liquid transport. The elbow is usually connected to the pipeline using a flange.

[0004] In conventional elbow production, drilling and grinding are required to ensure the sealing of the connection. Therefore, the elbow needs to be clamped. In streamlined production, the elbow needs to be positioned during clamping to ensure that the processing part corresponds to the processing equipment. Conventional clamping equipment is difficult to achieve accurate positioning, requiring manual intervention, which is time-consuming and labor-intensive and not conducive to the streamlined production process. Summary of the Invention

[0005] In view of this, the present invention provides a fixture for a diaphragm pump elbow to solve the above-mentioned technical problems.

[0006] A fixture for a diaphragm pump elbow includes a main body, a first clamping mechanism disposed on the main body, and a second clamping mechanism disposed on the main body. The diaphragm pump elbow is a product for assembling a diaphragm pump, including a first connecting end, a second connecting end, and multiple bolt holes disposed on the first and second connecting ends. The main body includes a base plate, a partition plate vertically disposed on the base plate, and multiple product positioning pins disposed on the partition plate. The partition plate has multiple insertion holes and multiple mounting holes concentrically disposed with respect to the insertion holes. Each product positioning pin is disposed on the surface of the partition plate and includes a floating pin disposed in the insertion hole, a spring disposed between the floating pin and the partition plate, and a pin sleeve disposed in the mounting hole. When the product positioning pins are set on the partition, four product positioning pins are set on each workstation. Two product positioning pins are set as a group and located on both sides of the partition. The four product positioning pins on both sides correspond to the positions of the bolt holes in the four rectangular arrays. The two product positioning pins on the same side correspond to the two bolt holes located diagonally. The first clamping mechanism includes a first driving component set on the base plate, a first pressure block set on the first driving component, multiple first support blocks set on one side of the first driving component, and multiple first leveling plates set on both sides of the first support blocks. One end of the first pressure block is fixed to the first driving component by fasteners, and the other end has a V-shaped notch with a clearance groove at the bottom of the V. The bottom of the first support block is fixed to the base plate by fasteners, and the top has a U-shaped notch. The second clamping mechanism includes a second driving component set on the base plate, a second pressure block set on the second driving component, multiple second support blocks set on one side of the second driving component, and multiple second leveling plates set on both sides of the second support blocks. One end of the second pressure block is fixed to the first drive assembly by fasteners, and the other end has a U-shaped bayonet.

[0007] Furthermore, four reinforcing ribs are provided on the first connecting end.

[0008] Furthermore, the main body also includes multiple tooling positioning pins disposed on the base plate, and two handles disposed on both sides of the partition.

[0009] Furthermore, the tooling positioning pin is a cylindrical pin that passes through the base plate, and four tooling positioning pins are provided, which are respectively located at the four corners of the base plate.

[0010] Furthermore, the floating pin includes a cylindrical body, an insertion end located at one end of the body, a support ring located on the body, and a spring groove located at the other end of the body away from the insertion end. The insertion end is a free end located at one end of the body, and the end is a frustum-shaped structure. The support ring is disposed on the body and is an annular structure with a diameter larger than the diameter of the body. The spring groove is a circular groove and is concentric with the body.

[0011] Furthermore, one end of the spring abuts against the bottom of the spring groove, and the other end abuts against the partition plate.

[0012] Furthermore, one end of the pin sleeve is a sleeve fitted over the outside of the floating pin, and the other end is an annular plate-like structure. The inner diameter of the plate-like structure is larger than the diameter of the main body and smaller than the diameter of the abutment ring.

[0013] Furthermore, the first driving component includes two slide rail structures arranged side by side, a connecting plate spanning the two slide rail structures, and two cylinders for driving the connecting plate to move. The extension direction of the slide rail in the slide rail structure is perpendicular to the partition plate. The connecting plate is fixed on the two sliders. The driving ends of the cylinders are respectively connected to both ends of the connecting plate. The driving direction is consistent with the extension direction of the slide rail. The structure of the second driving component is the same as that of the first driving component, but the driving direction is opposite.

[0021] 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.

[0022] like Figures 1 to 6 The diagram shows a structural schematic of the fixture for a diaphragm pump elbow provided by this utility model. The fixture includes a main body 10, a first clamping mechanism 20 disposed on the main body 10, and a second clamping mechanism 30 disposed on the main body 10. It is conceivable that the fixture may also include other functional modules such as fasteners, electrical control equipment, etc., which are technologies well known to those skilled in the art and will not be described in detail here.

[0023] The diaphragm pump elbow is a product 40 used for diaphragm pump assembly, including a first connecting end 41, a second connecting end 42, and multiple bolt holes 43 provided on the first connecting end 41 and the second connecting end 42. Both the first connecting end 41 and the second connecting end 42 are flange heads to facilitate flange connection. The first connecting end 41 is also provided with four reinforcing ribs 411 to enhance its structural strength. The bolt holes 43 are located on the flange heads of the first connecting end 41 and the second connecting end 42 and are arranged in a rectangular array to facilitate fastener insertion for flange connection.

[0024] The main body 10 includes a base plate 11, a partition 12 vertically disposed on the base plate 11, a plurality of tooling positioning pins 13 disposed on the base plate 11, a plurality of product positioning pins 14 disposed on the partition 12, and two handles 15 disposed on both sides of the partition 12.

[0025] The partition 12 can be fixed to the base plate 11 by fasteners and located on the center line of the base plate 11 to divide the base plate 11 into two areas, thereby providing the first clamping mechanism 20 and the second clamping mechanism 30 respectively.

[0026] The partition 12 is provided with a plurality of insertion holes 121 for mounting the product positioning pin 14, and a plurality of mounting holes 122 concentrically arranged with the insertion holes 121. Each insertion hole 121 is closed at the bottom and the opening direction is towards the first clamping mechanism 20 or the second clamping mechanism 30. The specific arrangement will be described in detail below in conjunction with the product positioning pin 14. The opening direction of the mounting hole 122 is consistent with that of the insertion hole 121, and the diameter is larger than that of the insertion hole 121, so as to form a snap-fit ​​step at the opening of the insertion hole 121, thereby for mounting the product positioning pin 14. The specific structure of the product positioning pin 14 will be described in detail below. Correspondingly, a plurality of fixing holes for fasteners can also be provided on the mounting hole 122.

[0027] The tooling positioning pin 13 is a cylindrical pin that passes through the base plate 11 and is used for positioning the fixture tooling of this application, so as to facilitate its placement on the working position of the production equipment. In one embodiment of this application, four tooling positioning pins 13 are provided and are respectively located at the four corners of the base plate 11.

[0028] Each of the product positioning pins 14 is disposed on the surface of the partition plate 12 and includes a floating pin 141 disposed in the insertion hole 121, a spring 142 disposed between the floating pin 141 and the partition plate 12, and a pin sleeve 143 disposed on the mounting hole 122.

[0029] The floating pin 141 can be a one-piece die-cast metal part or an injection-molded plastic part, and includes a columnar body 1411, an insertion end 1412 located at one end of the body 1411, a support ring 1413 located on the body 1411, and a spring groove 1414 located at the other end of the body 1411 away from the insertion end 1412. The insertion end 1412 is a free end located at one end of the body 1411, and the end is a frustum-shaped structure to form a guide structure so that the floating pin 141 can be inserted into the bolt hole 43. The support ring 1413 is disposed on the body 1411 and is an annular structure with a diameter larger than the diameter of the body 1411, so as to cooperate with the pin sleeve 143 to install the floating pin 141 in the insertion hole 121 and prevent the floating pin 141 from leaving the insertion hole 121 under the elastic action of the spring 142. The spring groove 1414 is a circular groove and is concentric with the main body 1411 to allow the spring 142 to be inserted and abutted. The bottom of the spring groove 1414 is provided with a through hole penetrating the main body 1411 to prevent the main body 1411 from being pressed on the partition 12 and sucked in by atmospheric pressure, thus preventing it from rebounding smoothly.

[0030] One end of the spring 142 abuts against the bottom of the spring groove 1414, and the other end abuts against the partition 12, so as to generate an elastic force on the floating pin 141 away from the partition 12.

[0031] The pin sleeve 143 can be fixed in the mounting hole 122 by fasteners. One end of the pin sleeve 143 is a sleeve that can be fitted over the floating pin 141, and the other end is an annular plate structure. The inner diameter of the plate structure is larger than the diameter of the main body 1411 and smaller than the diameter of the abutment ring 1413, so that the floating pin 141 can move within a certain range, and the pin sleeve 143 will not disengage from the insertion hole 121 due to the abutment of the abutment ring 1413.

[0032] When the product positioning pins 14 are set on the partition 12, four product positioning pins 14 are set on each workstation. Two product positioning pins 14 are set as a group and are located on both sides of the partition 12. The four product positioning pins 14 on both sides correspond to the positions of the bolt holes 43 in the four rectangular arrays. The two product positioning pins 14 on the same side correspond to the two bolt holes 43 located at opposite corners. This achieves stable positioning of the bolt holes 43 of the product on each side, while the product positioning pins 14 on both sides can avoid each other.

[0033] The handles 15 are provided on both sides of the base plate 11 in the extending direction to facilitate lifting of the tooling for handling and movement.

[0034] The first clamping mechanism 20 includes a first driving component 21 disposed on the base plate 11, a first pressing block 22 disposed on the first driving component 21, a plurality of first support blocks 23 disposed on one side of the first driving component 21, and a plurality of first leveling plates 24 disposed on both sides of the first support blocks 23.

[0035] The first driving component 21 includes two slide rail structures arranged side by side, a connecting plate spanning the two slide rail structures, and two cylinders for driving the connecting plate. The extension direction of the slide rails in the slide rail structures is perpendicular to the partition 12. The connecting plate is fixed on the two sliders. The driving ends of the cylinders are respectively connected to both ends of the connecting plate. The driving direction is consistent with the extension direction of the slide rails, thereby pushing the first pressure block 22 closer to and away from the partition 12.

[0036] One end of the first pressure block 22 is fixed to the first drive assembly 21 by fasteners, and the other end is provided with a V-shaped bayonet and an avoidance groove at the bottom of the V. When clamping the product 40, when the second connecting end 42 abuts against the partition plate 12, the first pressure block 22 can avoid the reinforcing rib 411 and press the tube body of the first connecting end 41.

[0037] The bottom of the first support block 23 is fixed to the base plate 11 by fasteners, and the top is a U-shaped opening so that the tube of the second connecting end 42 can be placed on it. The height of the first support block 23 is such that when the product 40 is placed on it, the bolt hole 43 on the second connecting end 42 corresponds to the position of the floating pin 141.

[0038] One end of the first contour plate 24 is fixed to the base plate 11 by fasteners, and the other end extends vertically upward. Two first contour plates 24 are provided on both sides of each first support block 23. The height of the first contour plate 24 is such that when the product 40 is placed on the first support block 23, it can support and abut against the flange of the first connecting end 41. The distance from the side of the first contour plate 24 away from the partition 12 to the partition 12 is less than the distance from the reinforcing ribs 411 on both sides of the first connecting end 41 to the partition 12, thereby preventing the first contour plate 24 from interfering with the reinforcing ribs 411 during the clamping process of the product 40.

[0039] The second clamping mechanism 30 includes a second drive assembly 31 disposed on the base plate 11, a second pressure block 32 disposed on the second drive assembly 31, a plurality of second support blocks 33 disposed on one side of the second drive assembly 31, and a plurality of second leveling plates 34 disposed on both sides of the second support blocks 33.

[0040] The second drive component 31 has the same structure as the first drive component 21, but the drive direction is opposite, thereby pushing the second pressure block 32 closer to and away from the partition 12.

[0041] One end of the second pressure block 32 is fixed to the first drive assembly 21 by fasteners, and the other end is provided with a U-shaped bayonet for pressing the tube body of the second connecting end 42.

[0042] The bottom of the second support block 33 is fixed to the base plate 11 by fasteners, and the top is a flat surface so that the flange of the first connecting end 41 can be placed on it. The height of the second support block 33 is such that when the product 40 is placed on it, the bolt hole 43 on the first connecting end 41 corresponds to the position of the floating pin 141.

[0043] One end of the second contour plate 34 is fixed to the base plate 11 by fasteners, and the other end extends vertically upward. Two second contour plates 34 are provided on both sides of each second support block 33. The height of the second contour plate 34 is such that when the product 40 is placed on the second support block 33, it can support and abut against the flange of the second connecting end 42.

[0044] Compared with the prior art, the clamping fixture for the diaphragm pump elbow provided by this utility model clamps the product 40 by setting the first clamping mechanism 20 and the second clamping mechanism 30. By adopting corresponding support and avoidance for the different shapes at both ends of the product 40, clamping is achieved separately. By setting the fixture positioning pin 13, the product 40 on both sides of the partition plate 12 is positioned and abutted respectively, ensuring that the product 40 will not slide or shift under the clamping of the first clamping mechanism 20 and the second clamping mechanism 30, thus ensuring the stability of clamping the product 40. At the same time, the use of an elastic guiding structure allows the product 40 to be quickly positioned, accelerating the efficiency of assembly line production.

[0045] 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.
