Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, and in particular to a machining fixture for compressor frames. Background Technology

[0002] Fixtures are a broad category of tools used in woodworking, metalworking, fitter work, machinery, electrical control, and other handicrafts. They are primarily used to assist in controlling position or movement. Fixtures can be divided into three categories: process assembly fixtures, project testing fixtures, and circuit board testing fixtures.

[0003] When machining a compressor frame, a jig is needed to fix it in place, so that it can be cut and ground. Existing jigs for compressor frames are usually manual and use a screw structure to fix the frame. However, when fixing with a screw structure, the screw needs to be turned manually, which is inefficient when there are many fixing points or a large workload. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a compressor frame machining fixture.

[0005] The technical solution of this utility model is: a compressor frame processing fixture, including a base; a plurality of fixing mechanisms disposed on the base for applying downward pressure to the compressor frame; a positioning plate mounted on the base for guiding the placement of the compressor frame; and a plurality of supporting mechanisms disposed on the base for supporting the compressor frame; wherein, the fixing mechanism includes: a cylinder vertically disposed on the base; a pressing member movably connected to the output shaft of the cylinder; a fixing block fixed to the cylinder and located below the pressing member; and a hinge plate whose two ends are movably connected to the pressing member and the fixing block respectively.

[0006] Furthermore, a bearing rod is rotatably connected to the cylinder output shaft, and the bearing rod is fixedly connected to the lower pressure member.

[0007] Furthermore, the fixing mechanism also includes: a support column disposed on the base and close to the base; a buffer pad disposed at the top of the support column, and the pressing end of the pressing member extending above the support column.

[0008] Furthermore, the bottom of the positioning plate is bent at a 90-degree angle to form a mounting component, which is used for screw penetration.

[0009] Furthermore, the top of the positioning plate is tilted outward and bent to form a guide plate.

[0010] Furthermore, the support mechanism includes: a hollow column vertically fixed to the base; a guide rod vertically slidably connected to the interior of the hollow column; a load-bearing head fixed to the guide rod extending to the outside of the hollow column; and a return spring sleeved on the outside of the guide rod, the two ends of which are respectively limited by the load-bearing head and the hollow column.

[0011] Furthermore, a screw that can be screwed onto the hollow column is provided.

[0012] Furthermore, the base is provided with a hook that is detachably threaded.

[0013] The beneficial technical effects of this utility model are as follows: With the setting of the fixing mechanism, when the frame is placed on the support mechanism, the cylinder can drive the tail end of the pressing part to rise through the output shaft when it works. Since the pressing part is rotatably connected to the fixing block through the hinge plate, the tail end of the pressing part will rotate around the hinge plate as the center when it rises, causing the pressing end to fall. The pressing end of the pressing part can be used to press down and fix the frame, thereby replacing the screw fixing method. This eliminates the need for operators to consume a lot of labor and can effectively improve work efficiency. Attached Figure Description

[0020] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0021] See appendix Figure 1-4 As shown, the compressor frame processing fixture of Embodiment 1 includes a base 1; several fixing mechanisms disposed on the base 1 for applying downward pressure to the compressor frame; a positioning plate 3 mounted on the base 1 for guiding the placement of the compressor frame; and several support mechanisms disposed on the base 1 for supporting the compressor frame.

[0022] The compressor frame can be positioned on the support mechanism by the positioning plate 3, and then fixed by the fixing mechanism to place the compressor frame in the designated position, which facilitates the subsequent processing of the frame.

[0023] The fixing mechanism includes: a cylinder 2 vertically mounted on the base 1; a pressing member 21 movably connected to the output shaft of the cylinder 2; a fixing block 23 fixed to the cylinder 2 and located below the pressing member 21; and a hinge plate 24 whose two ends are movably connected to the pressing member 21 and the fixing block 23 respectively.

[0024] When the frame is placed on the support mechanism, the cylinder 2 can drive the tail end of the pressing part 21 to rise through the output shaft. Since the pressing part 21 is rotatably connected to the fixed block 23 through the hinge plate 24, the pressing end will fall when the tail end of the pressing part 21 rises. The pressing end of the pressing part can be used to press down and fix the frame, thereby replacing the fixing method of the screw 44. This eliminates the need for operators to consume a lot of labor and can effectively improve work efficiency.

[0025] The lower pressure end can be protruded or recessed according to the structure of the fixing point, so as to better fit the frame.

[0026] Furthermore, a bearing rod 22 is rotatably connected to the output shaft of cylinder 2, and the bearing rod 22 is fixedly connected to the lower pressure member 21.

[0027] Furthermore, the fixing mechanism also includes: a support column 25 disposed on and near the base 1; a buffer pad 26 disposed at the top of the support column 25; and the pressing end of the pressing member 21 extending above the support column 25.

[0028] When the compressor frame is placed on the support mechanism, there is still a gap between it and the support column 25. When the frame is lowered by the pressure of the pressing member 21, it will be supported by the support column 25 to increase the support force. The buffer pad 26 can reduce rigid impact and avoid damage to the frame when it is pressed down.

[0029] Furthermore, the bottom of the positioning plate 3 is bent at a 90-degree angle to form a mounting piece 31, which is used for the screw to pass through.

[0030] The screws can be used to fix the positioning plate 3 to the base 1.

[0031] Furthermore, the top of the positioning plate 3 is tilted outward and bent to form a guide plate 32.

[0032] When the rack is placed vertically downwards, its position can be determined by the positioning plate 3, and the guide plate 32 will not obstruct the initial insertion of the rack, making the initial insertion of the rack more convenient and unobstructed.

[0033] Furthermore, the support mechanism includes: a hollow column 4 vertically fixed to the base 1; a guide rod 41 vertically slidably connected to the interior of the hollow column 4; a load-bearing head 42 fixed to the guide rod 41 and extending to the outside of the hollow column 4; and a return spring 43 sleeved on the outside of the guide rod 41, the two ends of which are limited by the load-bearing head 42 and the hollow column 4 respectively.

[0034] When the frame is supported by the support mechanism, the load-bearing head 42 will abut against the frame. The load-bearing head 42 will be supported by the return spring 43, so that the frame has a certain amount of room to move. When the fixing mechanism fixes the frame, it will squeeze the return spring 43. The elastic deformation of the return spring 43 can buffer the frame when it is fixed.

[0035] Furthermore, a screw 44 that can be screwed onto the hollow column 4 is provided.

[0036] The screw 44 can fix the hollow column 4 onto the base 1, thus realizing the installation of the hollow column 4.

[0037] Furthermore, the base 1 is provided with a hook 11 that is detachably attached by means of threads.

[0038] The hook 11 allows for easy rope connection, thus facilitating the placement and retrieval of the device.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
