Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioner housing processing and clamping technology, and in particular to a clamping fixture and automotive air conditioner housing processing and clamping device. Background Technology

[0002] The automotive air conditioning compressor is the heart of the automotive air conditioning refrigeration system, playing the role of compressing and transporting refrigerant vapor. Compressors are divided into two types: fixed displacement and variable displacement. According to different working principles, air conditioning compressors can be divided into fixed displacement compressors and variable displacement compressors.

[0003] Currently available clamping fixtures for machining automotive air conditioning housings typically clamp and fix the housing around its perimeter. However, since machining is required around the perimeter of the housing, some existing equipment, although equipped with a rotating device, lacks a structure that limits the movement of the housing. This can easily lead to misalignment when the housing is rotated, affecting the accuracy of subsequent machining.

[0004] Therefore, this utility model proposes a clamping fixture and a clamping device for processing automotive air conditioning housings to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping fixture and a clamping device for processing automotive air conditioning housings, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a clamping fixture and a clamping device for processing automotive air conditioning housings, comprising a worktable and a guide rail, wherein the guide rail is fixedly installed around the top surface of the worktable.

[0007] A drive motor is fixedly installed at the center of the bottom of the workbench, a rotating rod is fixedly installed on the top of the drive motor, and a disc is fixedly installed on the top of the rotating rod.

[0008] A lead screw is rotatably mounted on the surface of guide rail one. A slider is threaded onto the surface of lead screw one. A retaining ring is fixedly mounted on one side of the surface of slider one. A guide rail two is fixedly mounted on the top of slider one. A lead screw two is rotatably mounted on the surface of guide rail two. A slider two is threaded onto the surface of lead screw two. A pressure block is fixedly mounted on the bottom side of one side of slider two. A base is fixedly mounted on the bottom of the surface of guide rail two.

[0009] Preferably, a servo motor is fixedly installed on one side of the guide rail. The servo motor drives the lead screw to rotate, causing the slider to slide on the threaded surface of the lead screw, and simultaneously causing the retaining ring to make frictional contact with the surface of the placed disc.

[0010] Preferably, the retaining ring is a semi-circular ring, and there are four retaining rings in total. The four retaining rings are evenly distributed around the outer surface of the placement disk and are slidably engaged with the surface of the placement disk by a slider.

[0011] Preferably, the top of the disc is movably placed with the car air conditioner housing, and the bottom support is L-shaped, with the top engaging with the bottom surface of the car air conditioner housing.

[0012] Preferably, a servo motor is fixedly installed on the top of the guide rail. The servo motor drives the lead screw to rotate, and the slider drives the pressure block to rise and fall on the threaded surface of the lead screw, and engages with the top surface of the car air conditioner housing.

[0013] Preferably, support columns are fixedly installed around the bottom surface of the workbench, and a control panel is provided on the front of the workbench.

[0014] A clamping device for processing automotive air conditioning housings, characterized in that it includes clamping fixtures comprising any one of the above-mentioned features.

[0015] Compared with the prior art, the beneficial effects of this utility model are: The worktable's top four guide rails, in conjunction with a servo motor, drive a lead screw to rotate, causing a slider and four evenly distributed semi-circular retaining rings to slide precisely. This allows the retaining rings to make frictional contact with the surface of the placement disc, initially limiting the circumferential positioning of the automotive air conditioning housing on the disc, adapting to the circumferential fixing requirements of housings of different diameters. The placement disc is driven by a bottom drive motor via a rotating rod, allowing for multi-angle rotation of the housing in conjunction with processing steps, improving processing flexibility. The top guide rail of slider one, in conjunction with a servo motor, drives a lead screw to rotate, causing slider two and a pressure block to rise and fall, forming an upper and lower clamping structure with the L-shaped base at the bottom of guide rail two. The base supports the bottom of the housing, and the pressure block presses against the top of the housing, achieving longitudinal stability and secure fixing. The coordinated clamping in both the circumferential and longitudinal directions completely prevents housing displacement during processing. Simultaneously, the control panel allows for convenient operation of each motor, enabling precise adjustment of clamping parameters. The structural design of the four retaining rings and the L-shaped base ensures even force distribution on the housing, preventing clamping deformation. The entire device is adaptable to different specifications of air conditioning housings, offering high clamping efficiency and strong fixing reliability. Attached Figure Description

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example 1: Please refer to Figure 1 A clamping fixture and a clamping device for processing automotive air conditioning housings, comprising a worktable 100 and a guide rail 200, wherein the guide rail 200 is fixedly installed around the top surface of the worktable 100.

[0020] Support columns 101 are fixedly installed around the bottom surface of the workbench 100, and a control panel 102 is provided on the front of the workbench 100.

[0021] A drive motor 104 is fixedly installed at the center of the bottom of the workbench 100. A rotating rod 105 is fixedly installed on the top of the drive motor 104. A placement disc 103 is fixedly installed on the top of the rotating rod 105. An automotive air conditioner housing is movably placed on the top of the placement disc 103.

[0022] In use, the support columns 101 around the bottom of the workbench 100 provide a stable foundation for the whole, and the control panel 102 on the front provides an operating interface for the subsequent operation of various components; the drive motor 104 at the bottom center of the workbench 100 is the power source for rotation, which drives the placement disc 103 to rotate through the rotating rod 105 on the top, so that the angle of the car air conditioner housing on the top of the placement disc 103 can be adjusted during subsequent processing.

[0023] Example 2: Based on Example 1, please refer to... Figure 3 A servo motor 201 is fixedly installed on one side of the guide rail 200. The servo motor 201 drives the lead screw 202 to rotate, which causes the slider 203 to slide on the threaded surface of the lead screw 202, and simultaneously causes the retaining ring 204 to make frictional contact with the surface of the placed disk 103.

[0024] The retaining ring 204 is a semi-circular ring, and there are four of them. The four retaining rings 204 are evenly distributed around the outer surface of the placement disk 103, and are slidably engaged with the surface of the placement disk 103 by the slider 203.

[0025] In use, the center drive motor 104 at the bottom of the worktable 100 drives the placement disk 103, on which the car air conditioner housing is placed, to rotate via the rotating rod 105, providing a basis for adjusting the processing angle; the servo motor 201 on the surface of the guide rail 200 around the top of the worktable 100 drives the lead screw 202 to rotate, causing the threaded slider 203 to slide, and simultaneously causing the four evenly distributed semi-circular retaining rings 204 on one side of the slider 203 to move closer to the placement disk 103, so that the retaining rings 204 rub against the surface of the placement disk 103 and slide to engage, forming a stable limit on the housing on the placement disk 103 from the circumferential direction.

[0026] Example 3: Based on Example 2, please refer to... Figure 2 and Figure 4 A lead screw 202 is rotatably mounted on the surface of guide rail 200. A slider 203 is threaded onto the surface of lead screw 202. A retaining ring 204 is fixedly mounted on one side of the surface of slider 203. A guide rail 206 is fixedly mounted on the top of slider 203. A lead screw 208 is rotatably mounted on the surface of guide rail 206. A slider 209 is threaded onto the surface of lead screw 208. A pressure block 210 is fixedly mounted on the bottom side of one side of slider 209. A base support 205 is fixedly mounted on the bottom of the surface of guide rail 206. The base support 205 is L-shaped and its top is in contact with the bottom surface of the car air conditioner housing.

[0027] A servo motor 207 is fixedly installed on the top of the guide rail 206. The servo motor 207 drives the lead screw 208 to rotate. The slider 209 drives the pressure block 210 to rise and fall on the threaded surface of the lead screw 208 and engage with the top surface of the car air conditioner housing.

[0028] In use, the servo motor 201 on the guide rail 200 around the top of the worktable 100 drives the lead screw 202 to rotate, causing the slider 203 to slide. This causes the four evenly distributed semi-circular retaining rings 204 on one side of the slider 203 to move closer to and slide into the placement disk 103, thus limiting the housing in the circumferential direction. The guide rail 206 on the top of the slider 203 provides an adjustment basis for longitudinal clamping. The servo motor 207 on its top drives the lead screw 208 to rotate, causing the slider 209 to rise and fall, thereby raising and lowering the slider 209. The bottom pressure block 210 cooperates with the L-shaped base 205 at the bottom of the guide rail 206. The base 205 supports the bottom of the housing, and the pressure block 210 presses the top of the housing to form a stable longitudinal clamping. The circumferential retaining ring 204 limits the movement and works in conjunction with the longitudinal pressure block 210 and the base 205 to ensure that the housing does not shift during processing. At the same time, the drive motor 104 can drive the housing to rotate with the placement disc 103 to meet the processing requirements of multiple angles. The whole system achieves precise adjustment through multi-motor drive and lead screw transmission to adapt to the clamping requirements of housings of different specifications.
