TECHNICAL FIELD
[0001] The utility model relates to the technical field of fixture, especially relates to a rack plate automatic positioning fixture device. BACKGROUND
[0002] The air conditioner compressor is the core component of the air conditioner refrigeration system, which compresses the low-pressure gaseous refrigerant into high-pressure gaseous refrigerant through the motor operation, and drives the refrigerant to circulate in the closed loop of the air conditioner system. The pipeline system of the air conditioner compressor usually needs to be connected by using a special flange disc part when connecting, and the special flange disc part needs to be processed at the machining equipment.
[0003] At present, the flange disc part of the pipeline of the air conditioner compressor is usually clamped and machined by the inner support clamp during processing, but the clamping method of the existing inner support clamp when clamping the flange disc part is relatively simple, and the stress point is small, so that the stability of the flange disc part of the air conditioner compressor during clamping and machining is poor, which easily affects the machining quality of the flange disc part of the air conditioner compressor. Therefore, we propose a rack plate automatic positioning fixture device. UTILITY MODEL CONTENTS
[0004] The main purpose of the utility model is to provide a rack plate automatic positioning fixture device, which is provided with a limiting seat at the inner support chuck of the turning and milling composite main shaft, and a positioning pin is also provided for positioning the air conditioner compressor parts. After the inner support chuck and the limiting seat clamp and hold the air conditioner compressor parts in a limiting mode, the positioning pin is clamped into the groove on the surface of the air conditioner compressor parts for positioning and clamping. The fixture device and the rack plate form a relatively stable whole, which better adapts to the cooperative machining requirements of the air conditioner compressor parts and ensures that the air conditioner compressor parts can be automatically and stably clamped and machined at the inner support chuck. The problems in the background art can be effectively solved.
[0005] To achieve the above purpose, the technical scheme adopted by the utility model is as follows:
[0006] An automatic positioning fixture device for a machine frame includes a milling and turning spindle and an inner support chuck. The inner support chuck is installed at the milling and turning spindle. The device also includes a limiting seat, a support rod seat A, a support rod C, a positioning pin, a positioning block, a spring, a snap ring pin, a support rod B, a support rod A, and a support rod seat B. The outer sleeve of the inner support chuck's claws has a limiting seat for clamping and limiting air conditioning compressor parts. The surface of the milling and turning spindle's shaft disc is fixed with a support rod seat A for supporting and installing support rod C. A positioning pin for clamping and holding air conditioning compressor parts is installed in the head groove of support rod C via a snap ring pin. A positioning block is installed at the support rod C behind the positioning pin. A hexagonal screw that screws into a hexagonal nut extends rearward from the head groove of the positioning block. A spring is fitted outside the hexagonal screw and rests against the positioning block. Support rod C is installed below support rod A via support rod B, and support rod seat B is installed at the tail of support rod A.
[0007] Furthermore, the tail rod of the support rod C is locked to the seat of the support rod seat A by bolts, and the support rod C is screwed to the support rod B and the support rod A from bottom to top with bolts, and the tail rod of the support rod A is locked to the support rod seat B by bolts;
[0008] By adopting the above technical solution, the support rod C and the support rod seat A are bolted together, and the support rod C is also bolted together with the support rod B and the support rod A. At the same time, the support rod A and the support rod seat B are also bolted together. This connection method has the advantages of convenient installation and disassembly, and strong and reliable connection. It facilitates the installation, debugging, maintenance and replacement of parts of the clamping device in actual use, while ensuring the stability and rigidity of the entire support structure during operation, and can effectively support and position related parts.
[0009] Furthermore, pin holes are provided through the surfaces of the support rod C and the positioning pin, and snap ring pins are inserted and installed at the pin holes of the support rod C and the positioning pin.
[0010] By adopting the above technical solution, a snap ring pin can be inserted and installed at the pin hole of the support rod C and the positioning pin, and the positioning pin can rotate at the support rod C with the help of the snap ring pin.
[0011] Furthermore, a groove is provided on the surface of the support rod C behind the positioning pin, and a positioning block is inserted into the groove of the support rod C. A mounting hole for screwing bolts is vertically provided between the support rod C and the bottom surface of the positioning block.
[0012] By adopting the above technical solution, after the positioning block is clamped in the groove at the support rod C, the support rod C and the positioning block can be firmly connected by screw bolts.
[0013] Furthermore, the top of the pin block of the positioning pin has a protruding pin plate;
[0014] By adopting the above technical solution, the positioning pin and pin plate can be inserted into the groove of the air conditioner compressor parts for positioning and clamping.
[0015] Furthermore, a through hole is provided in the head block groove of the positioning block, and an internal hexagon screw protrudes backward from the through hole of the positioning block.
[0016] By adopting the above technical solution, the through hole of the positioning block can be used to screw in the internal hexagonal screw and the hexagonal nut for installation.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This utility model sets a limiting seat at the inner support chuck of the milling and turning composite spindle, and sets a positioning pin for positioning the air conditioner compressor parts. After the inner support chuck and the limiting seat limit the air conditioner compressor parts in an inward recessing clamping manner, the positioning pin is then engaged in the groove on the surface of the air conditioner compressor parts for positioning and clamping. This allows the fixture device and the frame plate to form a relatively stable whole, better adapting to the collaborative processing needs of the air conditioner compressor parts, and ensuring that the air conditioner compressor parts can be automatically and stably clamped at the inner support chuck for processing.
[0019] Furthermore, the bracket rod C and bracket rod seat A, the bracket rod C and bracket rod B, and the bracket rod A and bracket rod seat B are all connected by bolts. This method makes the installation and disassembly of the clamping device very convenient in actual use, and facilitates debugging, maintenance and replacement of parts. Attached Figure Description
