Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts manufacturing, in particular to a valve block workpiece processing tool. Background Art

[0002] The automobile expansion valve is installed at the inlet of the automobile evaporator and mainly plays a throttling role. After the high-temperature and high-pressure liquid refrigerant passes through the throttling hole of the expansion valve, it becomes a low-temperature and low-pressure mist-like hydraulic refrigerant, creating conditions for the evaporation of the refrigerant; at the same time, it controls the flow of the refrigerant. The expansion valve needs to be processed more precisely, so a specific fixture is needed to clamp and fix the expansion valve.

[0003] Chinese patent CN212311828U proposes a processing fixture for the valve body of an expansion valve, including a working platform, a fixture, a valve body placement plate, a first motor and an electro-hydraulic device. A valve body placement plate is provided in the middle of the top of the working platform, a rotating disk is provided in the middle of the top of the valve body placement plate, and a second motor is connected to the bottom of the rotating disk. Clamps are provided at both ends of the top of the valve body placement plate, a rubber pad is bonded to the inner end of the clamp, a shock-absorbing device is fixedly welded to the middle of the outer side of the clamp, the outer end of the shock-absorbing device is connected to the first motor, and the outer end of the first motor is connected to the electro-hydraulic device through a hydraulic rod. Ventilation holes are distributed at both ends of the top of the working platform, and a dust collection hopper is connected to the bottom of the ventilation hole. An activated carbon filter plate is provided on the inner side of the dust collection hopper.

[0004] However, in the above patent, the working status of each clamping component still needs to be manually identified when processing the expansion valve, which is relatively cumbersome and prone to misjudgment, affecting product production efficiency and quality.

[0005] Based on this, the present invention designs a valve block workpiece processing tool to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a valve block workpiece processing tool.

[0008] A valve block type workpiece processing tooling, comprising a support mounting block;

[0009] Several groups of processing raw materials are connected to the upper end of the support mounting block;

[0010] The support mounting blocks on the left side of the processing material are connected with self-detecting clamping components for clamping the processing material from the back and front and automatically detecting the working status;

[0011] The lower end of the processing raw material is connected to a positioning and pressing component for installing and positioning the processing raw material and pressing and fixing the processing raw material from the right side of the processing raw material;

[0012] The self-detection clamping assembly includes a clamping assembly and an airtightness self-detection assembly. The upper and rear ends of the support mounting block on the left side of the processing raw material are fixedly connected with the clamping assembly, and the support mounting block on the left side of the clamping assembly is fixedly connected with the airtightness self-detection assembly.

[0013] Furthermore, the clamping assembly includes a corner cylinder, a pressure plate and a pressure column. The upper end and the rear end of the support mounting block on the left side of the processed raw material are fixedly connected with the corner cylinder, the output end of the corner cylinder is fixedly connected with the pressure plate, the end of the pressure plate away from the corner cylinder is fixedly connected with the pressure column, the end of the pressure column close to the processed raw material is in contact with the processed raw material, and the left end of the pressure plate is in contact with the airtightness self-inspection assembly.

[0014] Furthermore, the airtightness self-test component includes a support block, a slide groove, an air inlet, an air outlet, a plunger, a spring and a ventilation groove. The support block on the left side of the pressure plate is fixedly connected to the support mounting block, the upper end of the support block is provided with a slide groove, the support block at the left end of the slide groove is provided with an air inlet, and the support block on the right side of the slide groove is provided with an air outlet. The inside of the slide groove is slidably connected to the plunger, the right end of the plunger is in contact with the pressure plate, a spring is fixedly connected between the left end of the plunger and the left inner wall of the slide groove, and the middle part of the plunger is provided with a ventilation groove.

[0015] Furthermore, the spring is always in a state of compression deformation.

[0016] Furthermore, the positioning and clamping assembly includes a positioning and mounting assembly and left and right positioning and clamping assemblies. The positioning and mounting assembly is connected to the support and mounting block at the lower end of the processed raw material, and the lower end of the processed raw material is connected to the positioning and mounting assembly. The left and right positioning and clamping assemblies are connected to the support and mounting block on the right side of the processed raw material, and the left ends of the left and right positioning and clamping assemblies are in contact with and connected to the processed raw material.

[0017] Furthermore, the positioning and mounting assembly includes a mounting groove, a first cylinder and a positioning stop block. A mounting groove is provided on the supporting mounting block at the lower end of the processed raw material, and the lower end of the processed raw material is clamped in the mounting groove. The first cylinder is fixedly connected to the supporting mounting block in front of the mounting groove, and the output end of the first cylinder is fixedly connected to the positioning stop block, and the positioning stop block is in contact with the processed raw material at one end close to the processed raw material.

[0018] Furthermore, the left and right positioning and clamping assemblies include a second cylinder, a driving pressure block and a clamping push block. The second cylinder is fixedly connected to the bottom of the support mounting block on the right side of the mounting groove. The output end of the second cylinder passes through the support mounting block and is fixedly connected to the driving pressure block. The left end of the driving pressure block is slidingly connected to the clamping push block. The lower end of the clamping push block is slidingly connected to the support mounting block. The left side wall of the clamping push block is in contact with the processed raw material.

[0019] Furthermore, the side walls of the driving pressing block and the pressing pushing block that are close to each other are inclined surfaces that fit together.

[0020] The utility model has the following technical effects:

[0021] When the positioning and pressing assembly has finished positioning the raw material for processing, the utility model starts the angle cylinder, the angle cylinder drives the pressure plate to rotate a quarter of a turn and move downward, the pressure plate drives the pressure column to rotate a quarter of a turn and move downward, so that the pressure column squeezes the raw material for processing from above and behind, thereby realizing the limited pressure of the raw material in the front and back directions and the up and down directions, ensuring the stability of the raw material during processing. At this time, due to the effect of the spring restoring force, the plunger moves to the rightmost end, and the air groove is located on the inner side of the air outlet hole, so that the air outlet hole is connected with the slide groove through the air groove, and the gas entering the slide groove from the air inlet hole is discharged through the air outlet hole, thereby detecting that the air flow in the slide groove increases, and when it is necessary to loosen the raw material for processing, the angle cylinder is started. The cylinder and the corner cylinder drive the pressure plate to move upward and rotate. When the pressure plate rotates to contact the plunger, it squeezes the plunger into the inside of the slide. At this time, the plunger squeezes the spring to cause the spring to compress and deform. When the plunger moves to the vent groove and separates from the air outlet, the air outlet is blocked by the plunger, so that the gas inside the slide cannot be distributed to form an airtight state, and the air flow inside the slide is reduced. It can be seen that when the gas leaks in the slide, the pressure plate drives the pressure column to press the processed raw materials. When the slide is in an airtight state, the pressure column separates from the processed raw materials. At this time, the processed raw materials are unlocked, so that the working status of each pressure plate can be judged by detecting the air tightness of the slide. There is no need to manually open the door to confirm with the naked eye, which improves work efficiency, reduces misjudgment of personnel operation, and makes production smoother.

[0022] When the pressing block moves to the left, it squeezes the raw material to the left, thereby realizing the positioning of the raw material and limiting and fixing the raw material in the left and right directions. When the front side wall of the raw material needs to be processed, it only needs to start the first cylinder to retract the positioning block. Under the limitation of the self-detecting pressing assembly and the pressing push block on the raw material, the front side wall of the raw material can be processed conveniently without replacing the fixture, thereby improving production efficiency.

[0043] The positioning and pressing assembly 3 includes a positioning and mounting assembly 31 and left and right positioning and pressing assemblies 32.
