Description

Technical Field

[0001] The utility model relates to the technical field of compressor housing manufacturing equipment, in particular to a compressor housing clamping and transporting device. Background Art

[0002] In the current compressor manufacturing process, the compressor housing needs to go through multiple processes such as stamping, casting, and machining. The transportation between these processes, especially the handling of semi-finished housings, has long been a bottleneck for improving production efficiency. In existing technologies, traditional clamping and handling methods have exposed many shortcomings when dealing with compressor housings with irregular shapes and diverse specifications. Specifically, they are reflected in the following aspects:

[0003] Clamping difficulties caused by irregular shapes: Compressor housings are usually irregular shapes such as semi-ovals and special-shaped curved surfaces, rather than standard circles or squares. This directly makes it difficult for traditional clamping tools to achieve stable and reliable clamping. For example, common claw-type or chuck-type fixtures need to be customized for workpieces of specific shapes and cannot adapt to the challenges posed by the irregular shape of the compressor housing. This leads to poor versatility, the need for frequent tooling replacement, and difficulty in meeting the needs of mass and flexible production. More importantly, irregular shapes can easily lead to unstable clamping, causing slippage, deviation, or damage during transportation, thereby affecting production efficiency and product quality, and even posing a safety hazard.

[0004] Tooling challenges caused by diverse specifications: Compressor housings come in numerous models, each with significant differences in size, shape, and weight, further exacerbating the versatility issues of traditional tooling. Different housing specifications often require the design and manufacture of specialized fixtures. This not only increases production costs but also prolongs the production lead time, making it impossible to meet the flexible production needs of multiple varieties and small batches. This also increases tooling storage and management costs. Frequent tooling changes not only reduce production efficiency but also increase operator workload and the potential for safety risks due to operational errors.

[0005] Therefore, there is an urgent need to develop a clamping device that can achieve automated and efficient transfer. Utility Model Content

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0026] The compressor casing clamping and transferring device provided in this embodiment is mainly used in compressor production lines to realize the automatic transfer of compressor casings between different processes. It effectively solves the problems of unstable clamping and low transfer efficiency caused by irregular casing shapes and diverse specifications in the existing technology, improves production efficiency and reduces labor intensity.

[0027] like Figures 1 to 4 As shown, the compressor casing clamping and transporting device of this embodiment includes:

[0028] Two guide rails 10 are arranged in parallel and opposite to each other, and are used to carry and guide the movement of the clamping head assembly 30.

[0029] The linear conveying mechanism 20 is provided between the two guide rails 10 and is used to convey the compressor casing along the conveying direction. In actual implementation, the linear conveying mechanism 20 can be in various forms such as chain type and belt type to meet different conveying requirements.

[0030] The clamping head assemblies 30 are arranged in pairs between the guide rails 10, and multiple groups are arranged in intervals along the conveying direction for clamping and transporting the compressor housing.

[0031] A driving mechanism (not shown) is connected to the chuck assembly 30 and is used to drive the chuck assembly 30 to move along the conveying direction. In actual implementation, the driving mechanism can be in various forms such as a motor and a cylinder to provide reliable power.

[0032] The clamping head assembly 30 includes a base 31, a follower 32, a guide pulley 33, a first arm 34 and a second arm 35. The base 31 is connected to the power output end of the driving mechanism (generally by bolt connection), and the follower 32 is slidably mounted on the lower surface of the base 31. The follower 32 slides relative to the base 31 and has a clamping direction perpendicular to the conveying direction. A mechanism is also provided between the base 31 and the follower 32 so that the follower 32 slides away from the clamping direction when no external force is applied and remains in the pre-clamping direction. The guide pulley 33 is rotatably mounted on the side of the follower 32 facing away from the clamping direction, with the axial direction of the guide pulley 33 perpendicular to the clamping direction. One end of each of the first arm 34 and the second arm 35 is pivotally connected to the side of the follower 32 facing away from the guide pulley 33. The first arm 34 and the second arm 35 are arranged at an angle to form a clamping opening for clamping the compressor housing, with the opening direction of the clamping opening being consistent with the clamping direction. Rubber blocks 37 are provided at the free ends of the first arm 34 and the second arm 35. The rubber blocks 37 are used to directly contact the compressor housing, increase the clamping friction, and prevent the housing from slipping or being damaged. During implementation, the material of the rubber blocks 37 can be selected based on the material of the housing to achieve the best clamping effect.

[0033] During operation, in the initial state, the clamping head assembly 30 is located on both sides of the compressor housing, and the return spring 36 makes the follower 32 in a position away from the clamping direction. At this time, the first arm 34 and the second arm 35 are not in contact with the compressor housing; when the driving mechanism drives the base 31 to move along the guide rail 10, it also drives the follower 32 to move along the conveying direction. When the follower 32 continues to move, the guide pulley 33 will gradually contact the guide rail 10. At this time, the guide rail 10 will apply a force to the guide pulley 33 that is opposite to the clamping direction of the follower 32. The force compresses the return spring 36 and prompts the follower 32 to move along the clamping direction, that is, the follower 32 gradually approaches the compressor housing. As the follower 32 moves along the clamping direction, the first arm 34 and the second arm 35 of the clamping head assembly 30 also move inward, and the two clamping ports opposite to each other gradually clamp the compressor housing firmly. Once the compressor housing is firmly clamped, the driving mechanism can drive the clamping head assembly 30 and the compressor housing to move to the work station that needs to be processed, such as deburring.

[0034] After completing a specific process, the driving mechanism continues to drive the base 31 to move until the guide pulley 33 disengages from the guide rail 10. At this time, the return spring 36 will be quickly released, pushing the follower 32 to slide in the direction away from the clamping. The movement of the follower 32 will directly cause the first arm 34 and the second arm 35 to release the compressor housing. At this time, the compressor housing continues to move under the drive of the linear conveying mechanism 20 to complete the unloading process.

[0035] In addition, the first arm 34 and the second arm 35 are pivotally connected to one end of the follower 32 and are both provided with mutually meshing gear teeth (not shown in the figure). This gear tooth meshing design enables the first arm 34 and the second arm 35 to maintain synchronous movement during the rotation process, that is, in actual application, by rotating the first arm 34 or the second arm 35, the gear tooth meshing structure will drive the other arm to rotate synchronously, so that the opening size of the clamping mouth can be adjusted conveniently and quickly to adapt to compressor housings of different specifications, thereby realizing the flexible clamping of housings of different sizes by the clamping head assembly 30, further improving the versatility and applicability of the device; and the rubber blocks 37 at the free ends of the first arm 34 and the second arm 35 have a certain elasticity, and will not cause excessive pressure on the housing surface even when the clamping force is large, thereby avoiding scratches or scrapes on the housing surface during clamping and transportation, and effectively protecting the surface quality of the compressor housing.

[0036] Through the above-mentioned structural design, the device realizes stable clamping and automatic transfer of irregularly shaped compressor casings, effectively improves production efficiency, and significantly reduces the labor intensity of workers.

[0037] In some embodiments, as Figure 2 、 Figure 3As shown, it also includes an L-shaped connecting plate 40, the first arm 34 and the second arm 35 are rotatably pivoted to one side plate of the L-shaped connecting plate 40, and the other side plate of the L-shaped connecting plate 40 is fixed with at least two threaded columns 41. The side of the follower 32 away from the guide pulley 33 is provided with a screw hole adapted to the threaded column 41, and the threaded column 41 is connected to the follower 32 through the screw hole.

[0038] In specific implementation, by rotating the threaded column 41 on the L-shaped connecting plate 40, the initial position of the clamping head assembly 30 in the clamping direction can be easily fine-tuned. This design provides a simple and effective adjustment method. For example, when it is necessary to clamp a smaller compressor housing, the threaded column 41 can be unscrewed a little, so that the initial position of the clamping head assembly 30 in the clamping direction moves outward (close to the side of the compressor housing), thereby reducing the initial width distance between the two clamping openings; conversely, when it is necessary to clamp a larger compressor housing, the threaded column 41 can be screwed in a little, so that the initial position moves inward, thereby increasing the initial width of the clamping opening. In this way, the clamping head assembly 30 can achieve adaptive clamping of compressor housings of different specifications without adjusting the installation position of the entire base 31, thereby improving the versatility and flexibility of the device, simplifying the operating steps, and shortening the adjustment time of the production line.

[0039] In some embodiments, as Figure 2 、 Figure 3 As shown, the L-shaped connecting plate 40 is provided with a plurality of positioning holes 42, and each of the first arm 34 and the second arm 35 is provided with at least one pin hole. The first arm 34 and the second arm 35 are fixedly connected to the positioning holes 42 on the L-shaped connecting plate 40 via a latch 38. Utilizing this structural design, after adjusting the opening size of the clamping opening, multiple positioning holes 42 are provided on the L-shaped connecting plate 40, and corresponding pin holes are provided on the first arm 34 and the second arm 35, and fixed using the latch 38. This allows the first arm 34 and the second arm 35 to be precisely fixed in different positions, avoiding unstable clamping caused by free movement. When the production line needs to switch from producing small-sized shells to large-sized shells, the operator only needs to pull out the latch 38, move the first arm 34 and the second arm 35 to the positioning hole 42 corresponding to the large-sized shell, and then reinsert the latch 38 to complete the adjustment.

[0040] In some embodiments, as Figure 2As shown, the side of the follower 32 facing away from the clamping direction is fixedly connected to a triangular wheel frame 50, and a wheel axle 51 is pivotally connected to the triangular wheel frame 50. The guide pulley 33 is a waist drum wheel coaxially fixed to the wheel axle 51. In a specific implementation, the triangular wheel frame 50 is firmly connected to the follower 32 by bolts, providing a solid support platform for the guide pulley 33, and the wheel axle 51 is pivotally connected to the triangular wheel frame 50 by means of bearings or bushings, so that the guide pulley 33 can rotate freely around the wheel axle 51. In addition, in this embodiment, the guide pulley 33 adopts the shape of a waist drum wheel, that is, the middle part of the wheel is concave. This design allows the contact surface of the guide pulley 33 to better fit the shape of the guide rail 10 when it contacts the guide rail, thereby improving the stability of the movement.

[0041] In some embodiments, the free ends of the first and second arms 34, 35 are provided with insertion holes, and the rubber block 37 has a connection portion that forms an interference fit with the insertion holes. This structure ensures a secure connection while facilitating maintenance, effectively improving the reliability and service life of the clamping and transferring device while also reducing production and maintenance costs.

[0042] In some embodiments, as Figure 3 、 Figure 4 As shown, a slot 311 is defined on the lower surface of the base 31, and the follower 32 has a guide portion 321 that slidably engages with the slot 311. Two return springs 36 are disposed within the slot 311, with the two ends of the return springs 36 respectively abutting against the guide portion 321 and the wall of the slot 311. In practice, the slot 311 is designed to precisely mate with the guide portion 321, ensuring that the guide portion 321 can slide smoothly within the slot 311. That is, when the follower 32 is moved by an external force, the guide portion 321 slides in a predetermined direction under the guidance of the slot 311, ensuring the stability of its motion trajectory. When the external force is removed, the two return springs 36 simultaneously act on the guide portion 321, pushing it back to its initial position, ensuring the rapid return of the follower 32.

[0043] In some embodiments, as Figure 3 、 Figure 4As shown, the guide slot 311 is provided with a guide rod 312 extending in the clamping direction. The return spring 36 is sleeved on the guide rod 312. The guide slide portion 321 is provided with a slide hole 322 that matches the guide rod 312. In a specific embodiment, the guide rod 312 is fixed to the bottom of the slide slot 311 and extends in the moving direction of the follower 32. The return spring 36 is sleeved on the guide rod 312 and restrained by the slide hole 322 on the guide slide portion 321. When the follower 32 is subjected to an external force and moves in the clamping direction, the guide rod 312 can provide precise guidance, preventing lateral deviation of the follower 32 and ensuring the stability of the motion trajectory. At the same time, under the guidance of the guide rod 312, the return spring 36 compresses and expands more smoothly, ensuring that the rebound force it provides always acts in the correct direction, thereby ensuring that the follower 32 can quickly and stably reset when no external force is applied.

[0044] The compressor casing clamping and transfer device provided in this embodiment, through its angled first and second arms, can stably clamp irregularly shaped casings, effectively preventing the risk of slippage or displacement. Furthermore, in conjunction with a linear conveying mechanism and a drive mechanism, it enables automated transfer of casings, significantly improving production efficiency and reducing manual labor. Furthermore, the device offers excellent versatility and flexibility. Through its adjustable and modular first and second arms, it can accommodate compressor casings of varying specifications and shapes, reducing the need for frequent tooling changes and lowering production costs.
