Description

Technical Field

[0001] The present invention relates to the field of mechanical technology, in particular to a four-axis hydraulic double-station tooling for a brake caliper based on continuous operation. Background Art

[0002] As key equipment in the caliper manufacturing field, hydraulic tooling plays an irreplaceable role in the entire production process. It is tailored for caliper manufacturing. With advanced hydraulic technology, it greatly improves the workers' operating efficiency and enables caliper production tasks to be completed more efficiently.

[0003] This tooling is a powerful tool for caliper manufacturing that combines efficiency and precision. In terms of efficiency, it reduces the time and errors of manual intervention through automated hydraulic operation, making the previously cumbersome caliper manufacturing process smoother and faster, significantly shortening the production cycle. In terms of precision, the hydraulic tooling provides stable and precise pressure control, ensuring that all caliper components are precisely matched during the manufacturing process, thereby guaranteeing the overall quality of the caliper.

[0004] However, there are many problems with the existing hydraulic caliper tooling. Its functions are relatively simple, mainly focusing on the hydraulic clamping of the main process of the caliper. Once the auxiliary process is involved, additional tooling must be added, which not only greatly prolongs the operation time, but also when changing the main process product, the operation of replacing the bridge plate is also very cumbersome, seriously affecting the convenience of operation.

[0005] In order to solve the processing difficulties of auxiliary processes, the existing technology adopts the solution of installing cylinders on the front and back sides of the bridge plate, but this brings many disadvantages. On the one hand, installing cylinders on the front and back sides greatly increases the space occupied by tooling, which restricts both the workshop layout and the equipment placement. At the same time, the cost of purchasing cylinders and their supporting air pipes is high, and the subsequent maintenance costs continue to rise. The air pipes need to be replaced regularly due to aging and damage, and the maintenance of cylinders also requires a large amount of capital investment. This undoubtedly increases production costs, compresses corporate profit margins, and weakens the price competitiveness of products in the market.

[0006] On the other hand, there are serious defects in installing a clamping mechanism on the back of the bridge plate. Since the clamping mechanism requires manual adjustment, even if two are adjusted at the same time, it is difficult to ensure the uniformity of the clamping action, and errors are inevitable. Moreover, during the processing, locking failure is prone to occur, causing the caliper to shake during processing. This not only seriously affects the product quality, but also causes deviations in the relative position of the processing tool and the caliper, resulting in a large number of defective and waste products, increasing production costs, but also greatly restricts the efficient and high-quality production of the caliper. The quality of products in different batches fluctuates greatly, making it difficult to meet the market demand for high-quality and high-precision calipers. Frequent manual operations also increase the labor intensity of workers, and are prone to operational errors due to fatigue and negligence, making it difficult to standardize and normalize the entire processing process.

[0007] To this end, the present invention proposes a four-axis hydraulic double-station tooling for a brake caliper based on continuous operation. Summary of the Invention

[0008] The purpose of the present invention is to provide a four-axis hydraulic double-station tooling for brake calipers based on continuous operation to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a four-axis hydraulic double-station tooling for brake calipers based on continuous operation, comprising a bridge plate, a hydraulic fixing part is symmetrically installed on the top of the bridge plate, a clamping plate is symmetrically fixedly connected to the bottom of the bridge plate, and processing parts are provided at the clamping plate and the hydraulic fixing part, the bridge plate is connected to an external driving device, a ratchet group is symmetrically installed on the outside of each hydraulic fixing part, a gear group is installed on the outside of the hydraulic fixing part, an energy storage part is installed between the gear group and the ratchet group, a limit box is installed on the outside of the energy storage part, and an auxiliary fixing part that cooperates with the gear group is installed on the bottom of the bridge plate;

[0010] When the hydraulic fixing part clamps the workpiece, it drives the ratchet group to rotate and drives the gear group to compress the energy storage part to a pre-tightened state. The limit box will lock the potential energy of the energy storage part. When the bridge plate is flipped over, the limit box releases the limiting effect on the energy storage part, and the energy storage part releases elastic potential energy to drive the gear group to move and clamp the workpiece on the back of the bridge plate through the auxiliary fixing part.

[0011] Preferably, the hydraulic fixing part includes a base plate and a hydraulic cylinder fixed to the surface of the bridge plate, and clamping blocks on both sides respectively connected to the hydraulic cylinder and the base plate for rotation. The rotation centers of the clamping blocks on each side extend and intersect with each other to form a rotating shaft located between the two clamping blocks.

[0012] Preferably, the gear set includes a driving gear column and a driven gear column which are rotatably connected to the top and bottom of the bridge plate respectively.

[0013] Preferably, a transmission belt 1 is connected between the driving gear column and the driven gear column, and the transmission belt 1 is specifically a belt.

[0014] Preferably, the energy storage member includes a telescopic rod having one end rotatably connected to the active gear column and the other end fixedly connected to the ratchet assembly, and a torsion spring arranged between the active gear column and the ratchet assembly.

[0015] Preferably, the ratchet group includes an active ratchet column rotatably connected to the top of the bridge plate and a driven ratchet column fixed to the fixed end of the telescopic rod. The torsion spring is fixed between the driven ratchet column and the active tooth column. When the active ratchet column rotates, it will drive the driven ratchet column to rotate toward the side close to the workpiece.

[0016] Preferably, a second transmission belt is connected between the active ratchet column and the rotating shaft of the clamping block, and the second transmission belt is specifically a toothed belt.

[0017] Preferably, the limit box includes a box body fixed to the top of the bridge plate, a sliding hole is transversely opened on the surface of the box body, a rod head tooth plate is slidably connected in the sliding hole, and the rod head tooth plate is engaged with the active gear column.

[0018] Preferably, the auxiliary fixing member includes a convex strip fixed to the bottom of the bridge plate, and a fixed rack is slidably connected to the surface of the convex strip. The shape of the fixed rack close to the workpiece is adapted to the shape of the workpiece, and the fixed rack is engaged with the driven gear column.

[0019] Preferably, a turning rod is fixedly connected between each of the adjacent fixed racks, a circular ring is fixedly connected to the outer surface of the turning rod, and the turning rod is arranged on a side away from the limit box.

[0020] Preferably, the external driving device is a four-axis machining center.

[0021] Preferably, the spring constant of the telescopic rod is smaller than the spring constant of the torsion spring.

[0022] Preferably, a concave hole is opened on the surface of the workpiece, and a convex column that matches the shape of the concave hole is fixedly connected to the surface of the clamping plate, and the convex column is used to perform preliminary positioning of the workpiece.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. This tooling greatly simplifies the operation process in the installation and disassembly of workpieces. When contacting and installing workpieces, the operator only needs to pull the crank to drive the fixed rack to achieve simultaneous clamping or loosening of multiple workpieces. Compared with the traditional tooling method that requires operating the fixtures one by one, this centralized operation method greatly saves time and labor costs, significantly improves work efficiency, and makes the entire processing process smoother and more convenient.

[0025] 2. The tooling cleverly uses the action of the hydraulic cylinder to assist in clamping the workpiece on the back of the bridge plate. When the hydraulic cylinder pushes the clamping block to clamp the top workpiece, it will drive a series of transmission components to move, and ultimately achieve stable clamping of the workpiece on the back of the bridge plate. This method of using hydraulic power for auxiliary clamping can provide continuous and stable clamping force, ensuring that the workpiece will not be displaced or shaken during the processing, thereby ensuring processing accuracy and product quality.

[0026] 3. The tooling has good versatility and can adapt to calipers of the same batch with different specifications. Since the movement of the hydraulic cylinder will affect the movement of subsequent fixed racks and other components, by adjusting the parameters of the hydraulic cylinder, it can flexibly adapt to calipers of different sizes and shapes. This means that when processing calipers of the same batch but with different specifications, the tooling does not need to frequently replace tooling parts, reducing production costs and equipment debugging time, and improving production flexibility and adaptability.

[0027] 4. The tooling is designed and manufactured using standard parts. This feature brings significant cost advantages and maintenance convenience. The use of standard parts makes the tooling parts highly versatile and interchangeable, reducing the procurement cost and inventory management cost of parts. At the same time, when the tooling fails, the standard parts are easy to obtain and replace, making the maintenance process simpler and faster, which can effectively reduce equipment downtime and improve production efficiency.

[0028] 5. The turning rod is set on the side away from the limit box. This layout design fully considers the actual operation needs of the operator. In actual operation, since the bridge plate needs to rotate, the position of the turning rod is convenient for the operator to hold and slide easily, avoiding inefficiency and misoperation caused by limited operating space or inconvenient operation. The operator can complete the sliding operation of the fixed rack more comfortably and conveniently, further improving work efficiency and operation accuracy.

[0029] 6. The structural design of the tooling fully considers the needs of protection and cleaning. Only the top of the bridge plate is equipped with a limit box for protection. This design can effectively prevent debris, coolant and other impurities from entering the ratchet group, especially the gap between the active ratchet column and the driven ratchet column, to avoid the normal operation and service life of the tooling due to the accumulation of impurities. At the same time, the auxiliary fixing structure at the bottom of the bridge plate is relatively open, which is convenient for operators to clean and maintain, ensuring that the tooling always maintains good working condition.

[0030] 7. This tooling innovatively introduces a concept similar to that of cylinders using external forces to store potential energy, while cleverly avoiding many of the drawbacks of traditional cylinder applications. During tooling operation, when the bridge plate flips, the energy storage component releases elastic potential energy, precisely driving the gear set, which in turn drives the auxiliary fixings to stably clamp the workpiece on the back of the bridge plate. Compared with traditional tooling, this design has obvious advantages. If traditional tooling has a cylinder component on the other side of the bridge plate, it not only requires complex air pipe line adjustments and high investment, but this tooling, through the unique energy storage component design, can ensure that each clamping action is highly consistent, greatly improving the stability of the operation. On the basis of stable clamping, it also effectively avoids the common locking failure problem of traditional tooling. This not only reduces hardware procurement and installation costs, but also significantly reduces subsequent maintenance costs, making the entire processing process more stable and efficient, providing a more reliable guarantee for caliper production.

[0031] 8. The advantages of this tooling are not only reflected in its innovative clamping design, but also in its high practicality and convenience, which fully meets the production needs of calipers. It is not limited to the single function of clamping calipers, but deeply integrates multiple functions to form an efficient production system.

[0032] In actual operation, although the tooling involves force conversion, such as the transmission and conversion of force through hydraulic cylinders, ratchet groups, gear groups and energy storage parts, the operator only needs to perform a few key steps to make the tooling play its full function. For example, in the clamping link, the operator only needs to place the workpiece in the specified position and start the hydraulic cylinder to complete the initial clamping. The subsequent energy storage, bridge plate flipping and clamping of the back workpiece and other actions can be carried out in an orderly manner relying on the structural design of the tooling itself. After the processing is completed, it is only necessary to simply operate the rod head tooth plate and the turning rod to easily complete the workpiece unloading. This simplified operation process greatly reduces the workload of the operator, reduces the possibility of human operation errors, and improves production efficiency. It truly makes complex technology serve simple operations, bringing higher benefits and quality assurance to caliper production. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0046] It should be noted that the external driving device only provides the function of rotating and processing the workpiece 9, and its working principle and specific structure are both existing technologies. Therefore, in view of the versatility of the above structure, its specific principle will not be described in detail later.

[0047] Please refer to Figures 1 to 10As shown, the present invention provides an embodiment: a four-axis hydraulic double-station tooling for brake calipers based on continuous operation, comprising a bridge plate 1, a hydraulic fixing part 2 is symmetrically installed on the top of the bridge plate 1, a clamping plate 3 is symmetrically fixedly connected to the bottom of the bridge plate 1, and processing parts 9 are provided at the clamping plate 3 and the hydraulic fixing part 2, the bridge plate 1 is connected to an external driving device, a ratchet group 4 is symmetrically installed on the outside of each hydraulic fixing part 2, a gear group 5 is installed on the outside of the hydraulic fixing part 2, an energy storage part 6 is installed between the gear group 5 and the ratchet group 4, a limit box 7 is installed on the outside of the energy storage part 6, and an auxiliary fixing part 8 that cooperates with the gear group 5 is installed on the bottom of the bridge plate 1;

[0048] When the hydraulic fixing part 2 clamps the workpiece 9, it drives the ratchet group 4 to rotate, and drives the gear group 5 to compress the energy storage part 6 to a pre-tightened state. The limit box 7 will lock the potential energy of the energy storage part 6. When the bridge plate 1 is flipped over, the limit box 7 releases the limiting effect on the energy storage part 6. The energy storage part 6 releases the elastic potential energy to drive the gear group 5 to move, and clamps the workpiece 9 on the back of the bridge plate 1 through the auxiliary fixing part 8.

[0049] It should be noted that the hydraulic fixing part 2 includes a base plate and a hydraulic cylinder fixed to the surface of the bridge plate 1, and clamping blocks on both sides that are rotatably connected to the hydraulic cylinder and the base plate, and the rotation centers of the clamping blocks on each side extend and intersect with each other to form a rotating shaft located between the two clamping blocks. The gear set 5 includes a driving gear column 51 and a driven gear column 52 that are rotatably connected to the top and bottom of the bridge plate 1, respectively. A transmission belt 1 is connected between the driving gear column 51 and the driven gear column 52, and the transmission belt 1 is specifically a belt. The energy storage component 6 includes a The telescopic rod 61 is connected to the active tooth column 51 at one end, and the other end is fixedly connected to the ratchet group 4, and a torsion spring 62 is provided between the active tooth column 51 and the ratchet group 4. The ratchet group 4 includes an active ratchet column 41 rotatably connected to the top of the bridge plate 1 and a driven ratchet column 42 fixed to the fixed end of the telescopic rod 61. The torsion spring 62 is fixed between the driven ratchet column 42 and the active tooth column 51. When the active ratchet column 41 rotates, it will drive the driven ratchet column 42 to rotate toward the side close to the workpiece 9, and the active ratchet column 41 will rotate. The wheel column 41 and the rotating shaft of the clamping block are connected by a transmission belt 2, which is specifically a toothed belt. The limit box 7 includes a box body 71 fixed to the top of the bridge plate 1, and a sliding hole is opened horizontally on the surface of the box body 71. A rod head tooth plate 72 is slidably connected in the sliding hole. The rod head tooth plate 72 is engaged with the active tooth column 51. The auxiliary fixing member 8 includes a convex strip 81 fixed to the bottom of the bridge plate 1. The surface of the convex strip 81 is slidably connected to a fixed rack 82. The shape of the fixed rack 82 close to the side of the workpiece 9 is the same as the shape of the workpiece 9. They are adapted to each other, the fixed rack 82 and the driven gear column 52 are meshed with each other, and adjacent fixed racks 82 are fixedly connected with a turning rod respectively, and the outer surface of the turning rod is fixedly connected with a circular ring, and the turning rod is arranged on the side away from the limit box 7. The external driving device is a four-axis machining center. The spring constant of the telescopic rod 61 is smaller than the spring constant of the torsion spring 62. A concave hole is opened on the surface of the workpiece 9, and a convex column that is adapted to the shape of the concave hole is fixedly connected to the surface of the splint 3. The convex column is used to perform preliminary positioning of the workpiece 9.

[0050] It should be noted that this hydraulic double-station tooling can complete the processing of both sides of the workpiece in one clamping through standardized positioning and clamping structure. This tooling is particularly suitable for the processing of calipers in the same batch. Since the various parameters of the tooling can be accurately set in advance according to the size and process requirements of the calipers in the same batch, no frequent adjustments are required during the entire processing process. This not only greatly improves the continuity of production, but also avoids errors caused by repeated adjustments of the tooling. The double-station design of the tooling can reduce the frequency of manual changing, and the stable processing process ensures the high consistency of the quality of calipers in the same batch. It is particularly suitable for the small and medium-sized batch high-precision production needs in the fields of automotive braking systems, rail transit braking devices, etc.

[0051] For details, please refer to the following in the initial stage: Figure 1 and Figure 8As shown, the workpiece 9 is placed on the hydraulic fixing part 2 on the top of the bridge plate 1, and the workpiece 9 is preliminarily positioned. Then, the hydraulic cylinder is started. When the hydraulic cylinder extends, it pushes the clamping block to rotate around its rotation connection point with the base plate, so that the clamping block gradually rotates toward the side close to the workpiece 9 until the workpiece 9 is firmly clamped, completing the initial clamping operation of the workpiece 9 on the top of the bridge plate 1.

[0052] Please refer to Figure 3 , Figure 4 as well as Figure 9 As shown, during the rotation of the clamping block, the rotating shaft of the clamping block on the same side rotates synchronously. The rotating shaft is connected to the active ratchet column 41 through a belt, thereby driving the active ratchet column 41 to rotate. Due to the ratchet shape design of the active ratchet column 41 and the driven ratchet column 42, when the active ratchet column 41 rotates, it will drive the driven ratchet column 42 to rotate synchronously in one direction. During this process, the rod head tooth plate 72 limits the rotation of the active tooth column 51, so the torsion spring 62 is compressed and the elastic potential energy is stored.

[0053] After completing the above operations, the four-axis machining center is controlled to drive the bridge plate 1 to flip until it is convenient for the operator to install other workpieces 9 on the splint 3 at the bottom of the bridge plate 1.

[0054] The operator then completes the positioning and installation of the workpiece 9 by matching the concave hole on the surface of the workpiece 9 with the convex column on the surface of the splint 3. After that, the operator slides the rod head tooth plate 72 so that it no longer engages with the active gear column 51, and the active gear column 51 is no longer restricted.

[0055] Since the energy storage member 6 releases elastic potential energy, it drives the active gear column 51 to rotate in the opposite direction, that is, to rotate in the direction away from the workpiece 9. At this time, the active gear column 51 drives the driven gear column 52 to rotate synchronously through the toothed belt. The rotation of the driven gear column 52 drives the fixed rack 82 to slide along the protruding strip 81 toward the side close to the workpiece 9 until the workpiece 9 is clamped.

[0056] Subsequently, the operator slides the rod head tooth plate 72 back to its original position, so that it meshes with the active gear column 51 again, restricting the rotation of the active gear column 51 . At this time, the main and auxiliary processes of the workpiece 9 can be started.

[0057] When the main and auxiliary processes are completed, the operator pulls out the rod head tooth plate 72 again to release the restriction on the active gear column 51. Then, the operator holds the ring on the outer surface of the crutch and slides the fixed rack 82 toward both sides. At this time, the movement of the fixed rack 82 drives the driven gear column 52 and the active gear column 51 to rotate synchronously.

[0058] Please refer to Figure 10As shown, during this process, the rotation of the active gear column 51 drives the driven ratchet column 42 to rotate. Since the driven ratchet column 42 is restricted by the active ratchet column 41, and when the spring constant of the torsion spring 62 is significantly greater than the telescopic rod 61, the torsion spring 62 is subjected to an external force, such as the torque generated by the rotation of the active gear column 51, the deformation amount is extremely small, and it can be approximately regarded as a rigid connection. At this time, the force generated by the operator sliding the fixed rack 82 will act preferentially on the telescopic rod 61. This is because the spring constant is small and easy to compress, rather than the torsion spring 62, thereby realizing the contraction of the telescopic rod 61. The contraction of the telescopic rod 61 can provide a movement space for the whole composed of the torsion spring 62, the active gear column 51 and the driven ratchet column 42. As the active gear column 51 continues to rotate, the telescopic rod 61 will also be continuously compressed to provide movement space and continuously make the driven ratchet column 42 and the active ratchet column 41 approach and move away from each other.

[0059] At this time, the driven ratchet column 42 rotates along the inclined surface of the active ratchet column 41 and continues to resist under the elasticity of the telescopic rod 61, while the operator continues to slide the fixed rack 82 until the workpiece 9 can be successfully removed.

[0060] Afterwards, the rod head tooth plate 72 is reset, and the bridge plate 1 is rotated again to remove the workpiece 9 on the top of the bridge plate 1, and the restriction of the hydraulic fixing part 2 on the workpiece 9 is released, thus completing a complete processing cycle.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
