Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a milling and drilling integrated fixture for a compressor bracket. Background Art

[0002] Compressor brackets are typically welded to the outside of the compressor housing and are used to secure the compressor within the system, ensuring stable operation. The key to compressor bracket design lies in its shape. A well-designed shape can better secure and support the compressor, preventing movement or vibration during operation, thereby ensuring compressor stability and efficiency.

[0003] The structural shape of the compressor bracket is generally complex, with uneven three-dimensional structures on the upper and lower surfaces and different heights on the left and right ends, making it difficult to clamp it during milling and drilling.

[0004] The existing fixture structure for clamping the compressor bracket consists of a pressure plate, a pull seat and a cylinder. The pressure plate is rotatably installed on the pull seat, and the cylinder pushes the pressure plate to tighten or disengage the bracket. The installation of the pull seat generally adopts a method of opening a sinking groove on the fixture, placing the pull seat in the groove and then fixing it with bolts. The clamping points on the upper end surface of the compressor bracket are at different heights, so the depth of the corresponding sinking groove is also not uniform. This makes it difficult to process the working surface of the fixture, and the height of the pull seat cannot be adjusted after installation. Utility Model Content

[0005] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, the utility model provides a compressor bracket milling and drilling integrated fixture which is simple to process and convenient for adjusting the pull seat height.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a compressor bracket milling and drilling integrated jig, including a mounting table, the compressor bracket is positioned and arranged on the mounting table, and the mounting table is provided with a clamping assembly that is respectively pressed against the front and rear end faces of the compressor bracket; the clamping assembly includes a pressure plate, a pull seat and a cylinder, the cylinder is fixed to the bottom surface of the mounting table, the cylinder piston rod passes through the mounting table and is hinged to the pressure plate connecting end, the middle part of the pressure plate is rotatably connected to the pull seat, the pull seat and the mounting table can be raised and lowered, and the cylinder pushes the pressing end of the pressure plate to press or disengage the front and rear end faces of the compressor bracket.

[0007] Preferably, the mounting plate is provided with a threaded hole corresponding to the position of the pull seat, and the lower end of the pull seat has a stud that matches the threaded hole. The pull seat and the mounting plate are connected by a threaded connection, which is simple and convenient to operate and reduces the difficulty of jig processing.

[0008] Furthermore, a swing arm is provided between the pressing plate and the pull seat, the upper end of the swing arm is hinged to the middle of the pressing plate through a pin shaft, and the lower end of the swing arm is hinged to the upper end of the pull seat through a pin shaft.

[0009] In order to better position the compressor bracket, the mounting plate is provided with a left positioning column supported on the bottom surface of the left end of the compressor bracket and a right positioning column supported on the bottom surface of the right end of the compressor bracket.

[0010] Since the pressing point at the left end of the compressor bracket is in a suspended state, in order to improve the supporting strength of the pressing point, a support column is fixed to the mounting plate on the inner side of the left positioning column, and the support column corresponds to the pressing end of the pressure plate pressed on the end face of the compressor bracket.

[0011] The beneficial effect of the present invention is that the present invention changes the conventional installation method of the prior art in which the pull seat is placed in a groove and then fixed with bolts, to a method in which the pull seat and the mounting plate are connected by threaded cooperation, which makes it easy to adjust the height of the pull seat, and only threaded holes need to be opened on the mounting plate, which also reduces the processing difficulty of the fixture.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0018] like Figure 1 、 Figure 2The shown compressor bracket milling and drilling integrated jig includes a mounting plate 1, two left positioning columns 4 distributed at a front-to-back spacing are embedded at the left end of the upper plane of the mounting plate 1, and two right positioning columns 5 distributed at a front-to-back spacing are embedded at the right end of the upper plane of the mounting plate 1. The left and right ends of the compressor bracket 2 are respectively positioned and supported on the left positioning column 4 and the right positioning column 5; at the same time, a concave cavity matching the bottom shape of the left end of the compressor bracket 2 is also opened on the mounting plate 1 on the inner side of the left positioning column 4.

[0019] A total of four sets of clamping assemblies 3 are installed on the mounting plate 1 between the left positioning column 4 and the right positioning column 5, two of which are spaced apart at the front and rear sides of the left end of the compressor bracket 2 to press the front and rear end faces of the left end of the compressor bracket 2; the other two sets of clamping assemblies 3 are spaced apart at the front and rear sides of the right end of the compressor bracket 2 to press the front side of the compressor bracket 2.

[0020] like Figure 3 As shown, the clamping assembly 3 includes a pressure plate 3-1, a pull seat 3-2 and a cylinder 3-3, wherein the cylinder 3-3 is fixed on the bottom surface of the mounting table 1, the piston rod of the cylinder 3-3 passes through the mounting table 1 and is hinged to the connecting end of the pressure plate 3-1 through a pin, the middle part of the pressure plate 3-1 is rotatably connected to the pull seat 3-2 through a pin shaft, and a swing arm 3-4 is provided between the pressure plate 3-1 and the pull seat 3-2, the upper end of the swing arm 3-4 is hinged to the middle part of the pressure plate 3-1 through a pin shaft, and the lower end of the swing arm 3-4 is hinged to the upper end of the pull seat 3-2 through a pin shaft.

[0021] A threaded hole is provided on the mounting plate 1 corresponding to the position of the clamping assembly 3, and the lower end of the pull seat 3-2 has a stud that cooperates with the threaded hole on the mounting plate 1. During installation, the height of the pull seat 3-2 on the mounting plate 1 can be easily adjusted by cooperating between the stud on the pull seat 3-2 and the threaded hole on the mounting plate 1, thereby meeting the clamping requirements of the left and right ends of the compressor bracket 2 with different heights.

[0022] Since the pressing point below the left end of the compressor bracket 2 is in a suspended state, a support column 6 is fixed to the mounting plate 1 on the inner side of the left positioning column 4. The support column 6 corresponds to the pressing end of the pressure plate 3-1 pressed on the end face of the compressor bracket 2, which can improve the supporting strength of the compressor bracket 2 at this position.

[0023] During installation, the bottom surface of the left end of the compressor bracket 2 is embedded in the concave cavity of the mounting table 1, and the left and right ends of the compressor bracket 2 are respectively positioned and supported on the left positioning column 4 and the right positioning column 5, and the position of the support column 6 is adjusted to support the bottom surface of the left end of the compressor bracket 2; then, by cooperating between the studs on the pull seat 3-2 and the threaded holes on the mounting table 1, the height of the pull seat 3-2 on the mounting table 1 is adjusted, and then the cylinder 3-3 is started, and the piston rod of the cylinder 3-3 extends to push the pressure plate 3-1 to rotate around the upper end of the swing arm 3-4, and the front end of the pressure plate 3-1 is pressed tightly against the end faces on both sides of the compressor bracket 2. After the compressor bracket 2 is positioned and clamped on the jig, the compressor bracket 2 can be milled and drilled; after the milling and drilling of the compressor bracket 2 is completed, the piston rod of the cylinder 3-3 retracts, pulling the front end of the pressure plate 3-1 up and disengaging from the end faces on both sides of the compressor bracket 2, and the processed compressor bracket 2 can be removed.

[0024] This fixture changes the conventional installation method in the prior art of opening grooves of different heights on the mounting plate 1, placing the pull seat 3-2 in the groove and then fixing it with bolts. The pull seat 3-2 is connected to the mounting plate 1 by threaded fitting, so that the height of the pull seat 3-2 can be adjusted as required to meet the clamping requirements, and the adjustment is convenient. Only corresponding threaded holes need to be opened on the mounting plate 1, which also reduces the overall processing difficulty of the fixture.

[0025] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
