Description

Technical Field

[0001] The invention relates to the technical field of tooling for compressor covers, and in particular to a turning tooling for a front cover of an air-conditioning compressor of a new energy vehicle. Background Art

[0002] In the turning process of the front cover of the air-conditioning compressor of new energy vehicles, tooling plays a vital role. It not only ensures the processing accuracy, but also prevents errors caused by vibration and displacement by firmly fixing the workpiece, and improves production efficiency, and reduces preparation time through fast and accurate clamping. At the same time, tooling is also an important guarantee for operational safety, effectively preventing the workpiece from getting out of control due to centrifugal force under high-speed rotation. In order to meet the processing requirements, the tooling must have high-precision positioning and repeated positioning capabilities to ensure the consistency of the workpiece position, as well as good adaptability to cope with the clamping requirements of different models of front covers. In actual applications, common types of tooling include mechanical, hydraulic / pneumatic, and specially customized tooling fixtures, each of which has the advantages of simple and reliable structure, easy adjustment, large clamping force, and high positioning accuracy, but it also needs to be flexibly selected according to the characteristics of the workpiece and processing requirements to ensure the smooth progress of the processing process.

[0003] The traditional fixture for the front cover of the compressor of new energy vehicles is limited by its single-station design mode, which integrates the product positioning and clamping functions. This has caused a series of safety hazards in actual operation. Specifically, when the operator is carefully positioning the product, if it is accidentally slightly touched by the outside world or an operating error occurs, the cylinder clamping mechanism of the fixture may respond immediately and move instantly, greatly increasing the risk of pinching the fingers or palms of the workers, posing a direct threat to the safety of the operators.

[0004] In addition, when it is necessary to change the processed product, the operator has to put his upper body deep into the core area of ​​the processing center or equipment. In this process, since cutting fluid is widely present as an indispensable chemical auxiliary material, its long-term inhalation or direct skin contact will cause irreversible damage to the respiratory system and skin health of the workers, seriously affecting their physical health and the comfort of the working environment. And it may also be accompanied by mechanical risks.

[0005] Therefore, it is very necessary to invent a turning tool for the front cover of the air-conditioning compressor of a new energy vehicle. Summary of the invention

[0006] The present invention provides a turning tool for the front cover of the air-conditioning compressor of a new energy vehicle. The present invention provides the following technical solutions: it includes a workstation conversion plate, a positioning base, a tooling fixture table and a lever cylinder. Two positioning bases arranged in a mirror-symmetrical manner are fixedly installed on the workstation conversion plate. One of the positioning bases is located between several of the lever cylinders, and the other positioning base is away from the lever cylinder. The lever cylinder is fixedly installed at the upper end of the tooling fixture table, and the workstation conversion plate is arranged in the middle position of the tooling fixture table.

[0007] Preferably, a conversion and adjustment mechanism is installed on the tooling fixture table, wherein the conversion and adjustment mechanism is connected to the workstation conversion plate.

[0008] Preferably, the tooling fixture table is provided with a through T-slot, and the cross-sectional shape of the slot is T-shaped, that is, the bottom slot wall of the slot is provided with bosses protruding inward equidistantly, and the bosses and the two side walls of the slot form a T-shaped cross-sectional structure, and the workstation conversion plate is arranged in the through slot of the tooling fixture table and fits with the slot body.

[0009] Preferably, support seats are fixedly installed on both sides below one end of the tooling fixture table, two support seats are provided, and the support seats are located below the lever cylinder.

[0010] Preferably, a reinforcing side plate is fixedly mounted on the outer side of each of the support seats, the reinforcing side plate is fixed to the side surface of the tooling fixture table, and the reinforcing side plate is a right-angled triangle structure.

[0011] Preferably, the conversion and adjustment mechanism includes a lifting plate, a cylinder, a spline shaft and a spline sleeve, one end of the lifting plate is fixed to the output end of the cylinder fixedly mounted on the tooling fixture table, the other end of the lifting plate is rotatably connected to the lower end of the spline shaft, the spline shaft slides through the spline sleeve, and is fixedly connected to the center of the workstation conversion plate.

[0012] Preferably, the spline sleeve is rotatably mounted on a fixing frame fixedly mounted on the fixture table, and the spline sleeve is located below the fixture table.

[0013] Preferably, the spline shaft is provided with a spline protrusion, and the spline sleeve is provided with a spline groove that fits with the spline protrusion of the spline shaft.

[0014] Preferably, the conversion and adjustment mechanism also includes a driven belt pulley, a driving belt pulley, a transmission belt and a driving motor component. The driven belt pulley is fixedly connected to the spline sleeve, and the driven belt pulley and the driving belt pulley are equipped with the transmission belt. The driving belt pulley is fixed to the output end of the driving motor component fixedly installed on the tooling fixture table.

[0015] Preferably, the transmission belt is an internally toothed belt, and the driven belt pulley and the driving belt pulley are provided with raised gear teeth that mesh with the transmission belt.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention abandons the single-station design mode of traditional fixtures. This innovative transformation is not only about the improvement of technical integration, but also about the profound consideration of operational safety. By introducing components such as station conversion plates, positioning bases, fixture tables and lever cylinders, and creatively adopting a double-station design, that is, clearly distinguishing between product positioning and clamping functions, the risk of accidental touch by operators during fine positioning is fundamentally avoided. This design effectively reduces the safety hazard of pinching fingers or palms, provides operators with a safer and more reliable working environment, and significantly improves the safety of the overall operation.

[0017] 2. Another highlight of the present invention is the ingenious design of its conversion and adjustment mechanism, which cleverly combines the advantages of belt drive, cylinder drive and spline sliding mechanism to achieve flexible and efficient station conversion. This innovation not only makes product position transfer easy and smooth, but also greatly simplifies manual operations during the processing, reducing unnecessary steps and waiting time. More importantly, it promotes the automation and intelligentization of the processing process, significantly improves processing efficiency, reduces dependence on manual operations, and improves the overall efficiency of the production line.

[0018] 3. The overall structural design of the present invention fully considers various needs in actual production. Through the separate design of the positioning and clamping double stations, it not only optimizes the production process, but also significantly reduces the potential risks in subsequent operations. Specifically, the removable design of the positioning station eliminates the need for workers to go deep into the processing equipment, thereby reducing direct contact with harmful substances such as cutting fluids and reducing health risks. At the same time, this design also reduces accidental injuries that may occur due to mechanical movement, providing strong support for safety management of the production site.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] As attached Figure 1-6 As shown: The turning tool for the front cover of the air-conditioning compressor of a new energy vehicle provided by the present invention comprises a workstation conversion plate 1, a positioning base 2, a tool fixture table 3 and a lever cylinder 5. Two positioning bases 2 arranged in a mirror-symmetrical manner are fixedly installed on the workstation conversion plate 1, one of the positioning bases 2 is located between a plurality of the lever cylinders 5, and the other positioning base 2 is far away from the lever cylinder 5. The lever cylinder 5 is fixedly installed at the upper end of the tool fixture table 3, and the workstation conversion plate 1 is arranged in the middle position of the tool fixture table 3. The positioning base 2 close to the lever cylinder 5 is a clamping station, and conversely, the station far away from the positioning base 2 is a positioning station.

[0028] Furthermore, the fixture table 3, as the core component of the entire fixture, not only carries the conversion adjustment mechanism 4, but also provides stable support and flexible adjustment capabilities for the workstation conversion plate 1 through its unique design. A through-going T-slot is provided on the fixture table 3. This design cleverly utilizes the structural advantages of the T-shaped cross-section. The T-slot body formed by the boss of the bottom groove wall and the two side walls realizes the tight fit and stable installation of the workstation conversion plate 1. This design not only ensures the stability of the workstation conversion plate 1 during the processing, but also facilitates its fine-tuning or quick replacement to meet the processing requirements of automobile air-conditioning compressor front covers of different specifications or shapes.

[0029] Furthermore, in order to further improve the load-bearing capacity and stability of the fixture table 3, support seats 7 are fixedly installed on both sides below one end thereof. These support seats are not only located below the lever cylinder 5, providing a solid support foundation for the entire device, but also further enhance the stability of the structure through the introduction of the reinforcement side plate 6. The reinforcement side plate 6 is fixed to the outer side of the support seat 7 and the side surface of the fixture table 3 in a right-angled triangle structure. This design not only optimizes the mechanical distribution, but also improves the overall impact resistance of the device, ensuring stability and safety during the processing.

[0030] Furthermore, the conversion and adjustment mechanism 4 is a key component for realizing the conversion and adjustment of the workstation, and its internal structure is complex and precise. The mechanism mainly includes components such as a lifting plate 41, a cylinder 42, a spline shaft 43 and a spline sleeve 44. The lifting plate 41 is driven by the cylinder 42 to move up and down, and its other end is rotatably connected to the lower end of the spline shaft 43. The spline shaft 43 is a core component for transmitting power and rotation. The spline protrusion on the spline shaft 43 fits tightly with the spline groove on the spline sleeve 44, ensuring smooth and accurate rotation. The spline sleeve 44 is rotatably mounted on the fixed frame 55 on the fixture table 3, providing stable support for the entire conversion process.

[0031] Furthermore, in order to realize the automation and intelligent control of the workstation conversion, the conversion and adjustment mechanism 4 also introduces components such as a driven belt pulley 46, a driving belt pulley 47, a transmission belt 48 and a driving motor component 49. These components together constitute an efficient power transmission system, wherein the transmission belt 48 serves as a bridge connecting the driven belt pulley 46 and the driving belt pulley 47, and through its internal tooth design, it meshes with the raised gear teeth on the belt pulley to achieve stable power transmission. The driving motor component 49 serves as the power source of the entire system, and drives the belt pulley 47 to rotate through the rotation of its output end, thereby driving the entire conversion and adjustment mechanism 4 to complete the task of workstation conversion and adjustment. This design not only improves the processing efficiency, but also reduces the complexity of manual operation and enhances the automation level of the processing process.

[0032] Here’s how it works: First, the initial state and preparation stage: During the turning process of the front cover of the automobile air-conditioning compressor, the tooling of the present invention is in the initial state. At this time, the station conversion plate 1 is firmly installed in the T-slot of the tooling fixture table 3, and the two positioning bases 2 are respectively fixed on both sides of the station conversion plate 1, and are distributed in a mirror-symmetrical manner. The two positioning bases 2 are fixed on the work surface of the machining center by fasteners. The conversion adjustment mechanism 4 will control the position change of the two positioning bases 2, so as long as the positioning base 2 close to the lever cylinder 5 is a clamping station, which is used to clamp the automobile air-conditioning compressor front cover to be processed during the processing; as long as the positioning base 2 is far away from the lever cylinder 5, it is set as a positioning station, which is used to place the front cover to be processed or has been processed for preliminary positioning. The lever cylinder 5 is fixedly installed at the upper end of the tooling fixture table 3, and is in a standby state, ready to provide clamping force when needed.

[0033] Then, the workpiece positioning and clamping process: Workpiece positioning: Open the machine door of the machining center, and control the machining center to move the worktable of the machining center toward the machine door until it reaches the end point. At this time, the positioning station will pass through the machine door and be exposed to the outside. Then, the front cover of the automobile air-conditioning compressor to be processed is placed on the positioning base 2 on the positioning station, that is, the positioning base 2 away from the lever cylinder 5. Through the precise design of the positioning base 2, the front cover is ensured to be accurately positioned in both the horizontal and vertical directions. At this time, the positioning base 2 on the clamping station is in an idle state, waiting to receive the positioned front cover.

[0034] Station conversion: Start the conversion adjustment mechanism 4, the cylinder 42 starts to work, the lifting plate 41 moves up with the help of the cylinder 42, and drives the station conversion plate 1 to move up. When it moves to a suitable height, the driving motor component 49 starts to work, and its output end rotates to drive the driving belt pulley 47 to rotate. The driving belt 48 (internal tooth belt) is meshed with the raised gear teeth on the driven belt pulley 46 to achieve stable power transmission. The rotation of the driven belt pulley 46 drives the spline sleeve 44 to rotate, and then the spline protrusion and the spline groove are tightly fitted to drive the spline shaft 43 and the lifting plate 41 connected thereto to rotate. Start the cylinder 42 again, and the lifting plate 41 moves downward with the help of the cylinder 42 until the station conversion plate 1 is reset to the T-slot of the fixture table 3, and then the positioned front cover is transferred from the positioning station to the clamping station.

[0035] Clamping operation: When the workpiece reaches the clamping station, the lever cylinder 5 starts to work, and its piston rod extends and pushes the clamping mechanism (directly integrated on the lever cylinder 5) to clamp the front cover. The magnitude and uniformity of the clamping force are ensured by the precise control and adjustment of the lever cylinder 5 to ensure stability and accuracy during the processing. At the same time, when the lever cylinder 5 is not working, the lever clamping mechanism is in a vertical state, which does not affect or interfere with the up and down movement of the station conversion plate 1.

[0036] Processing: After the front cover is clamped, the lathe starts the processing operation. At this time, the tooling remains stable to ensure that the front cover will not move or deform during the processing.

[0037] Station conversion and unloading: After processing is completed, repeat the above station conversion steps to transfer the processed front cover from the clamping station to the positioning station. Then, remove the front cover from the positioning base 2 manually or automatically, and prepare to place the next front cover to be processed.

[0038] During the whole process, the tooling of the present invention realizes efficient, stable and safe clamping and processing of the front cover of the automobile air-conditioning compressor during turning through the coordinated work of the work station conversion plate 1, the positioning base 2, the tooling fixture table 3, the lever cylinder 5 and the conversion adjustment mechanism 4.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
