Description

Technical Field

[0001] This utility model relates to the field of cylinder block processing technology, and in particular to a positioning device for processing air conditioning compressor cylinder blocks. Background Technology

[0002] The air conditioning compressor is a core component of an air conditioning system, primarily responsible for compressing low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure gas, which then releases heat in the condenser, thus achieving the function of cooling or heating. Air conditioning compressors typically consist of multiple precision components, with the cylinder block being one of the key parts. The manufacturing process of the cylinder block requires multiple precision machining steps, such as drilling, milling, and grinding, to ensure that its dimensional accuracy and geometric tolerances meet design requirements. Due to the complex structure of the cylinder block, precise positioning and fixation are necessary during machining. Traditional positioning methods usually rely on manual operation or simple fixtures, which are insufficient to meet the requirements of high-precision machining.

[0003] A search revealed that utility model patent CN216576781U discloses a machining and positioning device for an air conditioning compressor cylinder body. The device includes a mounting plate with a base fixed to its top. A slide rail is provided at the top of the base, and a sliding connector is connected inside the slide rail. A machining table is connected to the top of the sliding connector. Side plates are fixed to the left and right sides of the machining table, and a drive box is connected to the outer end of each side plate. A drive structure is installed inside the drive box, and a moving plate is connected to one side of the drive structure. A pressure plate is connected to the right side of the moving plate, and positioning posts are provided at the four corners of the moving plate near the pressure plate. A receiving box is fixed to the side of the side plate near the moving plate. Through the drive structure, moving plate, and pressure plate, the cylinder body can be limited and fixed, achieving precise positioning and making the equipment more efficient.

[0004] However, this machining positioning device has certain limitations; it cannot perform angle flipping or overturning operations while the cylinder body is clamped. In actual machining processes, the cylinder body typically requires multi-faceted machining. When overturning is required, the operator must first release the cylinder body from the clamping state, manually perform the overturning operation, and then reposition and clamp it. This process not only increases machining time and reduces production efficiency but may also introduce errors during multiple clamping operations, affecting machining accuracy.

The two sets of racks are respectively slidably connected to the top of the two sets of guide rails, and the two sets of external gear rings and the two sets of racks are separate. The two sets of racks are not meshed. The inside of each rack is threaded with a threaded rod.

[0029] The specific embodiments of this utility model will be described in further 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 its scope.

[0030] Please see Figure 1-10 This utility model provides a positioning device for machining air conditioner compressor cylinder bodies, including a positioning worktable 1 and two sets of clamping seats 7 for holding the cylinder bodies, with the two sets of clamping seats 7 arranged symmetrically. Support columns 2 are symmetrically fixed on the left and right sides of the upper surface of the positioning worktable 1. Fixed side plates 3 are slidably connected to the inner sides of the two sets of support columns 2. Height adjustment components 4 for adjusting the synchronous lifting and lowering of the two sets of fixed side plates 3 are connected inside the support columns 2. Side covers 31 are fixedly fastened to the side of the two sets of fixed side plates 3 away from the support columns 2 by bolts. A rotating cylinder 5 is rotatably connected to the center position of the side of the fixed side plate 3 away from the support columns 2. The end of the rotating cylinder 5 away from the fixed side plate 3 rotates through the side cover 31. A drive component 6 for driving the two sets of rotating cylinders 5 to rotate synchronously is connected inside the side cover 31. The two sets of clamping seats 7 are slidably connected to the side of the two sets of rotating cylinders 5 away from the fixed side plates 3, and an adjustment component 8 for adjusting the position of the clamping seats 7 is connected to one side of the rotating cylinder 5. A machining table 9 for placing the cylinder body is fixedly connected to the center position of the upper surface of the positioning worktable 1.

[0031] This invention uses a drive assembly 6 to drive two sets of rotating cylinders 5 to rotate synchronously, thereby enabling the rotating cylinders 5 to drive the two sets of clamping seats 7 and the cylinders held inside them to achieve angle flipping or overturning operations. Unlike traditional methods, when it is necessary to flip the cylinder, the operator does not need to release the cylinder clamps. Instead, the cylinder can be flipped or overturned directly by driving the two sets of rotating cylinders 5 to rotate synchronously through the drive assembly 6. This not only greatly reduces tedious manual operation and processing time, significantly improving production efficiency, but also effectively avoids the error problems that may be introduced by multiple clamping.

[0032] In this utility model, the height adjustment component 4 can indirectly adjust the height of the two sets of clamping seats 7 and the cylinder body clamped on their inner sides by adjusting the synchronous lifting of the two sets of fixed side plates 3. This allows the operator to conveniently and quickly control the height of the cylinder body to meet different processing needs and improve processing accuracy and efficiency.

[0033] Working principle: By adjusting component 8, the operator can drive two sets of clamping seats 7 to clamp and position the cylinder body placed on the processing table 9. After the cylinder body is clamped, the operator can perform processing operations on the cylinder body with the support of the processing table 9. If it is necessary to rotate or flip the cylinder body, the operator can first raise the height of the cylinder body held by the two sets of clamping seats 7 using the height adjustment component 4 to ensure sufficient rotation space between the bottom of the cylinder body and the processing table 9, thus providing sufficient freedom for subsequent flipping. Next, the operator drives the rotating cylinder 5 to rotate using the drive component 6, thereby causing the two sets of clamping seats 7 and the cylinder body held by them to rotate or flip. After flipping, the operator lowers the height of the two sets of clamping seats 7 and the cylinder body held by them again using the height adjustment component 4 until the cylinder body is stably placed on the processing table 9. At this time, the cylinder body is in a stable processing state, and the operator can then perform processing operations on the cylinder body with the support of the processing table 9.

[0034] Furthermore, vertical slide rails 11 are provided on the front and rear sides of the support column 2. The vertical slide rails 11 are fixedly connected to the upper surface of the positioning workbench 1. Multiple sets of pulleys 34 that slide and cooperate with the vertical slide rails 11 at the corresponding positions are fixedly connected to the side of the fixed side plate 3 near the support column 2.

[0035] Specifically, when the height adjustment component 4 adjusts the height of the two sets of fixed side plates 3, the fixed side plates 3 drive the pulley group 34 to slide inside the vertical slide rail 11 at the corresponding position. The cooperation between the vertical slide rail 11 and the pulley group 34 plays a guiding and positioning role for the fixed side plates 3, ensuring that the fixed side plates 3 can move smoothly along the path of the vertical slide rail 11.

[0036] Furthermore, the support column 2 has a hollow structure. A through slot 21 is provided on the side of the support column 2 near the fixed side plate 3. The upper end of one set of support columns 2 is fixedly connected to a motor fixing housing 22. The height adjustment component 4 includes two sets of threaded rods 41 and a motor 44. The two sets of threaded rods 41 are rotatably connected to the inside of the two sets of support columns 2, and the lower ends of the two sets of threaded rods 41 rotatably pass through the positioning worktable 1 and are fixedly fitted with synchronous pulleys 42. The outer sides of the two sets of synchronous pulleys 42 are fitted with and engaged with synchronous belts 43. The upper end of one set of threaded rods 41 rotatably passes through the support column 2 at the corresponding position and is fixedly connected to the output end of the motor 44. The motor 44 is fixedly connected to the inside of the motor fixing housing 22. The outer side of the threaded rod 41 is threadedly fitted with a nut seat 45, and the nut seat 45 is fixedly connected to the side of the fixed side plate 3 near the support column 2.

[0037] Specifically, when the position of the fixed side plate 3 needs to be adjusted by the height adjustment component 4, the control motor 44 operates. The output shaft of the motor 44 drives one set of threaded rods 41 to rotate. With the cooperation of the synchronous belt 43 and the two sets of synchronous pulleys 42, the other set of threaded rods 41 also rotates synchronously, thereby driving the nut seats 45 on the outside of the two sets of threaded rods 41 to move synchronously, and thus driving the two sets of fixed side plates 3 to move synchronously.

[0038] Furthermore, a horizontal connecting seat 33 is fixedly connected to the rear side of both sets of fixed side plates 3. A motor fixing housing 331 is fixedly connected to one end of the rear side of the horizontal connecting seat 33. A guide rail 32 is fixedly connected to the lower end of the side plate 3 near the side cover 31. Ear plates 321 are fixedly connected to both the front and rear ends of the upper surface of the guide rail 32. The drive assembly 6 includes two sets of external gear rings 61, two sets of racks 62, and a motor 66. The two sets of external gear rings 61 are respectively fixedly sleeved on the outside of the two sets of rotating cylinders 5. The two sets of racks 62 are respectively slidably connected above the two sets of guide rails 32, and the two sets of external gear rings 61 and the two sets of racks 62 are respectively meshed. Both sets of racks 62 are internally threaded with threaded rods 63. The threaded rods 63 are rotatably connected to the ear plates 321 at corresponding positions. The rear end of the threaded rods 63 passes through the ear plates 321 at corresponding positions and the transverse connecting seat 33 and is fixedly fitted with synchronous pulleys 64. The outer sides of the two sets of synchronous pulleys 64 are fitted with and engaged with synchronous belts 65. The two sets of synchronous pulleys 64 and synchronous belts 65 are both installed in the transverse connecting seat 33. One set of threaded rods 63 passes through the rear wall of the transverse connecting seat 33 and is fixedly connected to the output shaft of the motor 66. The motor 66 is fixedly connected to the inside of the motor fixing housing 331.

[0039] Specifically, when the cylinders held inside the two sets of clamping seats 7 need to be flipped, the second control motor 66 first starts operating. The second motor 66 drives one set of threaded rods 63 to rotate via its output shaft. With the cooperation of the second synchronous belt 65 and the two sets of synchronous pulleys 64, the other set of threaded rods 63 also rotates synchronously, causing the two sets of racks 62 to move in the same direction, thereby driving the two sets of external gear rings 61 and their inner rotating cylinders 5 to rotate synchronously. As the rotating cylinders 5 rotate, the cylinders inside the two sets of clamping seats 7 also synchronously complete the predetermined flipping operation.

[0040] Furthermore, a long slide bar 621 is fixedly connected to the lower surface of the rack 62, and the long slide bar 621 is slidably connected to the inside of the guide rail 32.

[0041] Specifically, when the rack 62 moves, it causes the long slider 621 to slide within the guide rail 32. During this process, the guide rail 32 guides the long slider 621 to move smoothly within the guide rail 32, preventing deviation or jamming.

[0042] Furthermore, a through hole 51 is provided on the side of the rotating cylinder 5 away from the fixed side plate 3. The adjustment assembly 8 includes a threaded short column 81, a central ring 82, and two sets of L-shaped seats 83. The threaded short column 81 is rotatably connected to the inside of the through hole 51. The central ring 82 is threadedly sleeved on the outside of the threaded short column 81. The two sets of L-shaped seats 83 are symmetrically fixed on both sides of the central ring 82. The ends of the two sets of L-shaped seats 83 away from the central ring 82 are fixedly connected to the clamping seat 7. A motor 3 84 is fixedly connected inside the rotating cylinder 5. The end of the threaded short column 81 extending into the inside of the rotating cylinder 5 is fixedly connected to the output shaft of the motor 3 84. A guide 52 is connected between the L-shaped seat 83 and the rotating cylinder 5.

[0043] Specifically, when it is necessary to clamp the cylinder body, the cylinder body can be placed on the machining table 9 first. Then, the two sets of motors 84 are started simultaneously. The output shaft of the motors 84 drives the threaded short column 81 on the corresponding side to start rotating. At this time, under the guidance of the guide 52, the center ring 82 will drive the clamping seat 7 to move towards the cylinder body through the two sets of L-shaped seats 83. Until the two sets of clamping seats 7 firmly clamp the cylinder body, thereby ensuring that the position of the cylinder body will not shift or loosen during subsequent processing. When it is necessary to release the clamping state of the cylinder body, simply control the motors 84 to rotate in the opposite direction.

[0044] Furthermore, the guide member 52 includes two sets of side ears 521, which are respectively fixed on the two side walls of the rotating cylinder 5. The side slide rail 522 is fixedly connected to the end of each set of side ears 521 away from the rotating cylinder 5. A slider 523 is fixedly connected to the side of the L-shaped seat 83 near the side slide rail 522. The slider 523 is slidably connected to the inside of the side slide rail 522 on the corresponding side.

[0045] Specifically, the guide member 52 serves as a guide, ensuring that the L-shaped seat 83 and the central ring 82 can only slide smoothly along the side slide rail 522 via the slider 523. When the threaded short post 81 begins to rotate, due to the threaded engagement between the threaded short post 81 and the central ring 82, the rotation of the threaded short post 81 transmits power to the central ring 82. At this time, the central ring 82 can only move the L-shaped seat 83 back and forth along the inner side of the side slide rail 522 under the constraint of the guide member 52 and guided by the slider 523.

[0046] The above are merely preferred embodiments of this utility model and are not intended to limit this 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 this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
