Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm pump processing, in particular to a thread turning processing fixture for a diaphragm pump. Background Art

[0002] Diaphragm pumps, also known as control pumps, are a primary type of actuator. They utilize power to change fluid flow by receiving control signals from a control unit. They are a new type of conveying mechanism capable of transporting a variety of corrosive liquids, liquids containing particles, and high-viscosity, volatile, flammable, and highly toxic liquids. Their structural characteristics are the stainless steel rotating fittings mounted on both sides of the pump body. Therefore, when connecting multiple sections of pipe, threads or flanges are required at the joints. Thinner pipes are generally connected using threads.

[0003] Existing threading equipment generally uses CNC lathes to facilitate assembly line operations. However, when using CNC machine tool fixtures, such as chucks and collets, conventional fixtures are not convenient for clamping because the diaphragm pump tubes have protrusions or bends. Therefore, it is necessary to design a fixture for threading diaphragm pump tubes. Summary of the Invention

[0004] In view of this, the utility model provides a thread turning fixture for a diaphragm pump to solve the above technical problems.

The chuck structure comprises a clamping jaw, a mounting ring mounted on the clamping jaw, a pressing assembly mounted on the clamping jaw, and a lifting assembly mounted on the clamping jaw. The clamping jaw comprises a disc-shaped base, a first jaw mounted on the base, and a second jaw spaced apart from and parallel to the first jaw. The first and second jaws extend in the axial direction of the base. The mounting ring is fixed to the base and is located on the other side of the base away from the first and second jaws. The pressing assembly is mounted on the first jaw and comprises a pressing rod mounted at the end of the first jaw and a pressing block mounted on the pressing rod. One end of the pressing rod is mounted at the end of the first jaw, and the other end extends toward the second jaw.

[0016] The following is a further detailed description of 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 scope of protection of the present invention.

[0017] like Figures 1 to 3, which is a schematic structural diagram of a threading fixture for a diaphragm pump provided by the present invention. The threading fixture for a diaphragm pump includes a CNC lathe 10 and a chuck structure 20 disposed on the CNC lathe 10. It is conceivable that the threading fixture for a diaphragm pump also includes other functional modules such as connection circuits and an electrical control unit. These are well known to those skilled in the art and will not be detailed here.

[0018] The CNC lathe 10 is one of the most widely used CNC machine tools. It is mainly used for cutting the inner and outer cylindrical surfaces of shaft parts or disk parts, the inner and outer conical surfaces of arbitrary cone angles, complex rotational inner and outer curved surfaces, and cylindrical and conical threads, and can also perform grooving, drilling, reaming, boring and boring. CNC machine tools automatically process the parts to be processed according to a pre-compiled processing program. It is an existing technology that is widely used in the field of industrial production and should be well known to those skilled in the art, so only a brief description is given here. A lathe spindle 11 and a thread turning tool 12 are provided in the CNC lathe 10. When in use, after the tubular workpiece is clamped by the chuck structure 20, the lathe spindle 11 drives the workpiece to rotate, and the thread is turned by the thread turning tool 12.

[0019] The CNC lathe 10 includes multiple other components, including but not limited to a CNC device, a bed, a spindle box, a tool holder feed system, a tailstock, a hydraulic system, a cooling system, a lubrication system, a chip conveyor, etc., which are all common technologies used in industrial production equipment, so they are not listed one by one in the specification and the drawings.

[0020] The chuck structure 20 is a clamping fixture mounted on the lathe spindle 11 to hold the product being processed and rotate it to complete various operations. The chuck structure 20 includes a clamping jaw 21, a mounting ring 22 mounted on the clamping jaw 21, a pressing assembly 23 mounted on the clamping jaw 21, and a lifting assembly 24 mounted on the clamping jaw 21.

[0021] The clamping jaw 21 includes a disc-shaped base 211, a first claw portion 212 disposed on the base 211, and a second claw portion 213 spaced apart from and parallel to the first claw portion 212. The first claw portion 212 and the second claw portion 213 are both perpendicularly disposed on the edge of the base 211 and may be integrally formed. They extend in the axial direction of the base 211 to form a U-shaped claw.

[0022] The mounting ring 22 is fixed to the base 211 and is located on the other side of the base 211 away from the first claw portion 212 and the second claw portion 213. The mounting ring 22 is an annular structure, concentrically arranged with the base 211, to enable the chuck structure 20 to rotate along its axis when secured to the spindle of the CNC lathe 10. The inner ring of the mounting ring 22 is provided with a threaded structure, which facilitates securing the chuck structure 20 to the spindle of the CNC lathe 10 and facilitates removal and replacement.

[0023] The pressing assembly 23 is disposed on the first claw 212 and includes a pressing rod 231 disposed at the end of the first claw 212 and a pressing block 232 disposed on the pressing rod 231. One end of the pressing rod 231 is disposed at the end of the first claw 212, specifically at the free end away from the base 211, and the other end extends toward the second claw 213. The pressing rod 231 may pass through the first claw 212 and be controlled by a hydraulic mechanism. The pressing mechanism may be a hydraulic, electric, or pneumatic mechanism, as known to those skilled in the art, and is not specifically limited herein. The pressing block 232 is fixed to the end of the pressing rod 231, specifically at the end of the pressing rod 231 away from the free end of the first claw 212. The pressing block 232 has a V-shaped clamping opening, the edges of which may be provided with anti-slip grooves to facilitate gripping of the tubular workpiece during the pressing process.

[0024] The lifting assembly 24 includes two lifting rods 241 provided on the second claw portion 213, and a lifting block 242 spanning the two lifting rods 241. One end of the lifting rod 241 is provided on the second claw portion 213, and the other end extends toward the first claw portion 212. The arrangement direction of the two lifting rods 241 is consistent with the extension direction of the second claw portion 241. The driving mode and installation structure of the lifting rod 241 are consistent with those of the pressing rod 231. The lifting block 242 is provided with two V-shaped clamping openings, and the edges of the clamping openings can be provided with anti-slip grooves. In addition, the clamping opening on the pressing block 232 is located between the two clamping openings of the lifting block 242, so that when the pressing block 232 and the lifting block 242 are clamped, the force on the workpiece is more stable, thereby ensuring the stability of the clamping.

[0025] Compared with the prior art, the threading processing fixture for diaphragm pumps provided by the utility model performs threading operations on products by setting the CNC lathe 10, with high operating efficiency, and can cooperate with robots for streamlined production. By setting the chuck structure 20, automatic clamping of products is achieved, and it can be expanded to cooperate with robots for loading and unloading operations to meet the needs of streamlined production. Moreover, the chuck structure 20 is specially customized according to the specifications of the product, and is more suitable for the product than ordinary chucks on the market. It has strong rigidity and avoids tool vibration. The chuck structure 20 can be set in different sizes and replaced, has strong versatility, is compatible with products of different specifications, and is easy to maintain.
