Description

Technical Field

[0001] The utility model relates to the technical field of a jig for processing compressor parts, in particular to a jig for processing compressor parts. Background Art

[0002] The jig for compressor parts processing is a tool specially used to assist workers in performing compressor parts processing operations. Some jigs can be regarded as a type of fixture if they have the function of controlling the position and fixing the workpiece. The main function of this tool is to ensure the stability and accuracy of the parts during the processing, thereby improving work efficiency and product quality.

[0003] According to the prior art patent publication number CN 219542901 U, a compressor casing processing fixture is provided with a sliding adjustment groove, a sliding rod and a bolt. This design can adjust the height of the sliding block to adapt to compressor casings of various heights. However, each time the patented fixture fixes the compressor casing, it is necessary to manually unscrew the fixing lock bolts on one side of the two sliding blocks to adjust the clamping height. This process is complicated to operate, and manually adjusting the two sliding blocks separately cannot accurately ensure that the two sliding blocks are at the same level.

[0004] Therefore, a jig for processing compressor parts is needed to solve the problem in the prior art that the two sliding blocks cannot be synchronously adjusted to rise or fall. Utility Model Content

[0005] In order to solve the above technical problems, a jig for processing compressor parts is provided, which solves the problem in the prior art that the two sliding blocks cannot be synchronously adjusted to rise or fall.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a jig for processing compressor accessories, comprising a bottom plate and two vertical rods symmetrically fixed to one side of the top surface of the bottom plate, the vertical rods are slidably provided with adjustment rods, one end of the adjustment rod is threaded with a screw rod, and the opposite ends of the two screw rods are fixed with clamping blocks, characterized in that: the other end of the adjustment rod is provided with a synchronous lifting mechanism for pushing the two adjustment rods, and the synchronous lifting mechanism includes a connecting block fixed to the other ends of the two adjustment rods, an extension plate arranged below the connecting block, two limiting blocks fixed to both sides of the top surface of the extension plate, and a double-sided screw rod rotatably connected between the two limiting blocks;

[0007] A folding shielding component is provided between the connecting block and the bottom plate to prevent debris from splashing onto the double-sided screw;

[0008] The extension plate is fixed on the side wall of the base plate, and transmission blocks are threadedly sleeved on both sides of the double-sided screw rod. One side of the transmission block is slidably connected to the side wall of the base plate, and two fixed blocks distributed at intervals are fixed to the bottom surface of the connection block. The two transmission blocks correspond to the two fixed blocks respectively, and a support rod is hinged between the transmission block and the fixed block.

[0009] Preferably, the folding shielding component includes a plurality of baffles stacked between the connecting block and the bottom plate and two slide rails symmetrically arranged at both ends of the baffles, and the plurality of baffles are hinged in sequence.

[0010] Preferably, a rotating handle is mounted on the limiting block, and one end of the double-sided screw rotates through the limiting block and is fixed to the output shaft of the rotating handle.

[0011] Preferably, sliding columns are fixed at the centers of both ends of the baffle, and the sliding columns are slidably arranged in the slide rails. The baffle on the top layer is hinged to the bottom surface of the connecting block, and the baffle on the bottom layer is hinged to the top surface of the bottom plate.

[0012] Compared with the prior art, the advantages of the utility model are:

[0013] (1) Through the setting of the synchronous lifting mechanism, when it is necessary to adjust the clamping height of the clamping block, the handle can be rotated to drive the double-sided screw to rotate, causing the two transmission blocks to move relative to or away from each other along the rod body of the double-sided screw, and then the connecting block on the top surface of the fixed block is pushed up or down through the support rod. The rise or fall of the connecting block drives the two adjusting rods to rise or fall synchronously, thereby solving the problem of the inability to synchronously adjust the rise or fall of the two sliding blocks in the prior art.

[0014] (2) By setting up the folding shielding component, when the connecting block drives the adjusting rod to rise, it pulls one side of the upper baffle plate, causing several stacked baffle plates to be driven to rise together, and one side of the bottom baffle plate is pulled by the top surface of the bottom plate, causing several baffle plates to unfold. During this process, the sliding columns at both ends of the baffle plate slide in the sliding rail. Similarly, when the connecting block drives the adjusting rod to descend, it pushes the baffle plate on the top layer to drive several baffle plates to descend together. In this way, the baffle plate can be used to prevent the debris generated by the processing of the compressor casing from splashing onto the double-sided screw. At the same time, the rising, unfolding and descending stacking of the baffle plate will not hinder the rising or falling of the connecting block. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0021] Reference Figure 1 , Figure 2 and Figure 3 As shown, a jig for processing compressor parts includes a base plate 1 and two vertical rods 8 symmetrically fixed to one side of the top surface of the base plate 1, and an adjusting rod 3 is slidably arranged on the rod body of the vertical rod 8. A screw rod 5 is threaded through one end of the adjusting rod 3, and a clamping block 4 is fixed to the opposite ends of the two screw rods 5.

[0022] By setting the adjusting rod 3, the clamping block 4, the screw 5 and the vertical rod 8, when the compressor casing needs to be processed, the compressor casing is placed on the top surface of the base plate 1 between the two vertical rods 8, and then the height of the two adjusting rods 3 on the vertical rods 8 is adjusted according to the height of the casing, and then the two screws 5 are rotated, so that the screws 5 are threadedly rotated forward on the adjusting rods 3, and the two clamping blocks 4 are driven to move relative to each other until the compressor casing in the middle is clamped.

[0023] However, in practice, when the jig is used to clamp the compressor housing, the heights of the adjustment rods 3 on the two vertical rods 8 need to be adjusted respectively, and manual adjustment is difficult to ensure that the two adjustment rods 3 are at the same level.

[0024] In order to solve the above problem, it is worth noting that a synchronous lifting mechanism for pushing the two adjusting rods 3 is provided at the other end of the adjusting rod 3 .

[0025] The synchronous lifting mechanism includes a connecting block 2 fixed to the other end of the two adjusting rods 3, an extension plate 6 arranged below the connecting block 2, two limiting blocks 10 fixed to both sides of the top surface of the extension plate 6, and a double-sided screw 9 rotatably connected between the two limiting blocks 10. The extension plate 6 is fixed to the side wall of the base plate 1, and transmission blocks 11 are threadedly sleeved on both sides of the rod body of the double-sided screw 9. One side of the transmission block 11 is slidably connected to the side wall of the base plate 1. Two fixed blocks 12 distributed at intervals are fixed to the bottom surface of the connecting block 2. The two transmission blocks 11 correspond to the two fixed blocks 12 one by one, and a support rod 7 is hinged between the transmission block 11 and the fixed block 12. A turning handle 13 is installed on one of the limiting blocks 10, and one end of the double-sided screw 9 rotates through the limiting block 10 and is fixed to the output shaft of the turning handle 13.

[0026] Through the setting of the synchronous lifting mechanism, when it is necessary to adjust the clamping height of the clamping block 4, the handle 13 can be rotated to drive the double-sided screw 9 to rotate, causing the two transmission blocks 11 to move relative to or away from each other along the rod body of the double-sided screw 9, and then the connecting block 2 on the top surface of the fixed block 12 is pushed up or down through the support rod 7, and the rise or fall of the connecting block 2 is used to drive the two adjusting rods 3 to rise or fall synchronously, thereby solving the problem of the inability to synchronously adjust the rise or fall of the two sliding blocks in the prior art.

[0027] After using it for a period of time, it was found that the debris generated during the processing of the compressor housing often splashed onto the double-sided screw 9, causing the threaded engagement between the double-sided screw 9 and the transmission block 11 to damage the thread.

[0028] Further, refer to Figures 1 to 3 As shown, it is worth noting that a folding shielding component is provided between the connecting block 2 and the base plate 1 for preventing debris from splashing onto the double-sided screw 9 .

[0029] The folding shielding component includes a plurality of baffles 14 stacked between the connecting block 2 and the base plate 1 and two slide rails 15 symmetrically arranged at both ends of the baffles 14. The plurality of baffles 14 are hinged in sequence. A slide column 16 is fixed at the center of both ends of the baffle 14. The slide column 16 is slidably arranged in the slide rail 15. The top baffle 14 is hinged to the bottom surface of the connecting block 2, and the bottom baffle 14 is hinged to the top surface of the base plate 1.

[0030] By setting the folding shielding component, when the connecting block 2 drives the adjusting rod 3 to rise, one side of the upper baffle 14 is pulled, so that several stacked baffles 14 are driven to rise together, and one side of the bottom baffle 14 is pulled by the top surface of the bottom plate 1, so that several baffles 14 are unfolded. During this process, the sliding columns 16 at both ends of the baffle 14 slide in the sliding rail 15. Similarly, when the connecting block 2 drives the adjusting rod 3 to descend, the baffle 14 on the top layer is pushed to drive several baffles 14 to descend together. During this process, since the two ends of the baffle 14 are restricted by the sliding columns 16 and the sliding rails 15, several baffles 14 can only be stacked layer by layer between the bottom plate 1 and the connecting block 2. In this way, the baffle 14 can prevent the debris generated by the processing of the compressor casing from splashing onto the double-sided screw 9. At the same time, the rising, unfolding and descending stacking of the baffle 14 does not hinder the rising or falling of the connecting block 2.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
