Description

Technical Field

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

[0002] As a key device in the field of caliper manufacturing, the hydraulic tooling plays an irreplaceable role in the entire production process. It is specifically customized for caliper manufacturing. With advanced hydraulic technology, it greatly improves the operation efficiency of workers, enabling the caliper production task to be completed more efficiently.

[0003] This kind of tooling is a sharp weapon for caliper manufacturing that combines high efficiency and precision. In terms of high efficiency, through automated hydraulic operations, it reduces the time and errors of manual intervention, making the originally cumbersome caliper manufacturing process smoother and faster, and significantly shortening the production cycle. In terms of precision, the hydraulic tooling can provide stable and accurate pressure control, ensuring that all components of the caliper can achieve high-precision fitting during the manufacturing process, thus guaranteeing the overall quality of the caliper.

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

[0005] To solve the problem of auxiliary process machining, the existing technology adopts the scheme 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 floor space occupied by the tooling, restricting both the workshop layout and the equipment placement. At the same time, the cost of purchasing cylinders and their supporting air pipe lines is high, and the subsequent maintenance cost also continues to rise. The air pipes need to be replaced regularly due to aging and damage, and a large amount of capital investment is required for the repair and maintenance of the cylinders, which undoubtedly raises the production cost, compresses the enterprise profit space, and weakens the price competitiveness of the product in the market.

[0006] On the other hand, installing a clamping mechanism on the back of the bridge plate also has serious defects. Since this clamping mechanism requires manual adjustment, even if two are adjusted simultaneously, it is difficult to ensure the unity of the clamping action, and errors will inevitably occur. Moreover, during the processing, the locking failure is likely to occur, resulting in the caliper shaking during processing. This not only seriously affects the product quality, causing deviations in the relative position between the processing tool and the caliper, resulting in a large number of defective and waste products, increasing the production cost, but also greatly restricts the efficient and high-quality production of the caliper. The product quality fluctuates greatly among different batches, 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 it is easy to cause operation errors due to fatigue and negligence, making it difficult to standardize and regularize the entire processing process.

[0007] Therefore, the present invention proposes a four-axis hydraulic double-station tooling for brake calipers 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 purpose, the present invention provides the following technical solution: A four-axis hydraulic double-station tooling for brake calipers based on continuous operation, including a bridge plate. Hydraulic fixing parts are symmetrically installed on the top of the bridge plate. Clamping plates are symmetrically and fixedly connected to the bottom of the bridge plate, and workpieces are arranged at both the clamping plates and the hydraulic fixing parts. The bridge plate is connected to an external driving device. Ratchet groups are symmetrically installed on the outside of each hydraulic fixing part. Gear groups are installed on the outside of the hydraulic fixing parts. Energy storage parts are installed between the gear groups and the ratchet groups. A limit box is installed outside the energy storage parts. An auxiliary fixing part that cooperates with the gear group is installed at the bottom of the bridge plate; 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 the pre-tightened state. The limit box will lock the potential energy of the energy storage part. When the bridge plate is flipped, the limit box releases the limiting effect on the energy storage part, and the energy storage part releases the elastic potential energy to drive the gear group to act, and clamps the workpiece on the back of the bridge plate through the auxiliary fixing part.

[0010] Preferably, the hydraulic fixing part includes a base plate and a hydraulic cylinder fixed on the surface of the bridge plate, and clamping blocks rotatably connected to the hydraulic cylinder and the base plate on both sides respectively. The rotation centers of each clamping block extend and intersect with each other to form a rotating shaft located between the two clamping blocks.

[0011] Preferably, the gear group includes a driving tooth column and a driven tooth column rotatably connected to the top and bottom of the bridge plate respectively.

[0012] Preferably, a first transmission belt is drivingly connected between the driving tooth column and the driven tooth column, and the first transmission belt is specifically a belt.

[0013] Preferably, the energy storage member includes a telescopic rod with one end rotatably connected to the driving tooth column and the other end fixedly connected to the ratchet wheel set, and a torsion spring disposed between the driving tooth column and the ratchet wheel set.

[0014] Preferably, the ratchet wheel set includes a driving ratchet wheel column rotatably connected to the top of the bridge plate and a driven ratchet wheel column fixed to the fixed end of the telescopic rod. The torsion spring is fixed between the driven ratchet wheel column and the driving tooth column. When the driving ratchet wheel column rotates, it will drive the driven ratchet wheel column to rotate toward the side close to the workpiece.

[0015] Preferably, a second transmission belt is drivingly connected between the driving ratchet wheel column and the rotating shaft of the clamping block, and the second transmission belt is specifically a toothed belt.

[0016] Preferably, the limiting box includes a box body fixed to the top of the bridge plate. A sliding hole is horizontally formed 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 meshes with the driving tooth column.

[0017] Preferably, the auxiliary fixing member includes a convex strip fixed to the bottom of the bridge plate. A fixed rack is slidably connected to the surface of the convex strip. The shape of the side of the fixed rack close to the workpiece is adapted to the shape of the workpiece, and the fixed rack meshes with the driven tooth column.

[0018] Preferably, a turning rod is fixedly connected between every two adjacent fixed racks at intervals. A circular ring is fixedly connected to the outer surface of the turning rod, and the turning rod is disposed on the side away from the limiting box.

[0019] Preferably, the external driving device is a four-axis machining center.

[0020] Preferably, the spring constant of the telescopic rod is less than the spring constant of the torsion spring.

[0021] Preferably, concave holes are formed on the surface of the workpiece, and convex columns adapted to the shapes of the concave holes are fixedly connected to the surface of the clamping plate. The convex columns are used for initially positioning the workpiece.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The operation process is greatly simplified in the installation and disassembly links of the workpiece. When contacting and installing the workpiece, the operator only needs to pull the turning rod to drive the fixed rack to act, so as to simultaneously clamp or loosen multiple workpieces. Compared with the traditional tooling that needs to operate the fixtures one by one, this centralized operation method greatly saves time and labor costs, significantly improves work efficiency, and makes the whole processing process more smooth and convenient.

[0023] 2. The tooling cleverly utilizes the movement 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 finally 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 displace or shake during the processing, thus guaranteeing the processing accuracy and product quality.

[0024] 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 components such as the fixed rack, by adjusting the parameters of the hydraulic cylinder, it can flexibly adapt to calipers of different sizes and shapes. This enables the tooling to process calipers of the same batch but with different specifications without frequently replacing tooling components, reducing the production cost and equipment debugging time, and improving the flexibility and adaptability of production.

[0025] 4. The tooling is designed and manufactured using standard parts, which brings significant cost advantages and maintenance convenience. The use of standard parts makes the components of the tooling have high versatility and interchangeability, reducing the procurement cost and inventory management cost of the components. At the same time, when the tooling fails, since the standard parts are easy to obtain and replace, the maintenance process is simpler and faster, which can effectively reduce the equipment downtime and improve the production efficiency.

[0026] 5. The toggle rod is arranged on the side far 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, and at this time the position of the toggle rod is convenient for the operator to easily hold and slide, avoiding inefficiencies and misoperations caused by limited operation space or inconvenient operation. The operator can complete the sliding operation of the fixed rack more comfortably and conveniently, further improving the work efficiency and operation accuracy.

[0027] 6. The tooling fully considers the requirements of protection and cleaning in its structural design. Only the top of the bridge plate is provided with a limit box for protection. This design can effectively prevent impurities such as debris and coolant from entering the ratchet group, especially the gap between the driving ratchet column and the driven ratchet column, avoiding the normal operation and service life of the tooling affected by the accumulation of impurities. At the same time, the auxiliary fixing structure at the bottom of the bridge plate is relatively open, facilitating the operator to clean and maintain, ensuring that the tooling always maintains a good working state.

[0028] 7. This tooling innovatively introduces a concept similar to storing potential energy by external force in the cylinder part, yet cleverly avoids many drawbacks in the application of traditional cylinder parts. During the operation of the tooling, when the bridge plate flips, the energy storage part releases elastic potential energy, precisely driving the gear set to act, and then driving the auxiliary fixing part to stably clamp the workpiece on the back of the bridge plate. Compared with traditional tooling, this design has obvious advantages. If a cylinder part is set on the other side of the bridge plate in traditional tooling, not only complex tracheal line adjustments are required, incurring high costs, but this tooling can ensure that each clamping action is highly consistent through a unique energy storage part design, greatly improving the stability of operation. On the basis of stable clamping, it effectively avoids the common locking failure problem of traditional tooling. This not only reduces the hardware procurement cost, installation cost, but also significantly reduces the subsequent maintenance cost, making the entire processing process more stable and efficient, providing a more reliable guarantee for caliper production.

[0029] 8. The advantages of this tooling are not only reflected in the innovative clamping design, but also in its high practicality and convenience, fully meeting the production requirements of calipers. It is not limited to the single function of clamping calipers, but deeply integrates multiple functions to form an efficient production system. In actual operation, although force conversion is involved inside the tooling, such as force transmission and conversion through hydraulic cylinders, ratchet groups, gear sets, and energy storage parts, etc., the operator only needs to perform a few key steps to make the tooling exert all its functions. For example, in the clamping process, the operator only needs to place the workpiece at the designated position and start the hydraulic cylinder to complete the initial clamping. A series of actions such as subsequent energy storage, bridge plate flipping, and clamping of the workpiece on the back can be carried out orderly relying on the structural design of the tooling itself. After processing, only by simply operating the rod head tooth plate and the toggle lever can the workpiece be easily unloaded. This simplified operation process greatly reduces the working intensity of the operator, reduces the possibility of human operation errors, improves production efficiency, and truly makes complex technology serve simple operations, bringing higher benefits and quality guarantees for caliper production.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] It should be noted that the external driving device only provides the functions of rotating and processing the workpiece 9, and its working principle and specific structure are both prior arts. Therefore, due to the generality of the above structure, the specific principle will not be described in detail hereinafter.

[0034] Please refer to as Figures 1 to 10 shown, the present invention provides an embodiment: A four-axis hydraulic double-station tooling for brake calipers based on continuous operation, including a bridge plate 1, hydraulic fixing members 2 are symmetrically installed on the top of the bridge plate 1, clamping plates 3 are symmetrically and fixedly connected to the bottom of the bridge plate 1, and workpieces 9 are provided at both the clamping plates 3 and the hydraulic fixing members 2. The bridge plate 1 is connected to an external driving device. Ratchet wheel groups 4 are symmetrically installed on the outer sides of each hydraulic fixing member 2, gear groups 5 are installed on the outer sides of the hydraulic fixing members 2, energy storage members 6 are installed between the gear groups 5 and the ratchet wheel groups 4, limit boxes 7 are installed outside the energy storage members 6, and auxiliary fixing members 8 that cooperate with the gear groups 5 are installed at the bottom of the bridge plate 1; 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 locks 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 its 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.

[0035] It should be noted that the hydraulic fixing member 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, respectively. 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 an active 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 active gear column 51 and the driven gear column 52, and the transmission belt 1 is specifically a belt. The energy storage member 6 includes a The telescopic rod 61 is rotatably connected to the active tooth column 51 at one end and fixedly connected to the ratchet group 4 at the other end, and a torsion spring 62 is arranged 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. A transmission belt 2 is connected between the wheel column 41 and the rotating shaft of the clamping block, and the transmission belt 2 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 meshed 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, and a fixed rack 82 is slidably connected on the surface of the convex strip 81. The shape of the fixed rack 82 close to 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 turning rods in pairs, 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 adapted to the shape of the concave hole is fixedly connected to the surface of the splint 3, and the convex column is used to preliminarily position the workpiece 9.

[0036] 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 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, there is no need for frequent adjustments during the entire processing process. It 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 small and medium-sized batches of high-precision production needs in the fields of automotive braking systems, rail transit braking devices, etc.

[0037] For details, please refer to the following in the initial stage: Figure 1 and Figure 8 As shown, the workpiece 9 is placed on the hydraulic fixing part 2 on the top of the bridge deck 1, and the workpiece 9 is preliminarily positioned. Then, the hydraulic cylinder is started. When the hydraulic cylinder is extended, the clamping block is pushed to rotate around the rotation connection point between the hydraulic cylinder and 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, thereby completing the initial clamping operation of the workpiece 9 on the top of the bridge deck 1.

[0038] 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, and 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.

[0039] 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 processed parts 9 on the clamping plate 3 at the bottom of the bridge plate 1.

[0040] The operator then completes the positioning and installation of the workpiece 9 by matching the concave holes on the surface of the workpiece 9 with the convex columns on the surface of the splint 3. After that, the operator slides the rod head tooth plate 72 so that it is no longer engaged with the active tooth column 51, and the active tooth column 51 is no longer restricted.

[0041] As the energy storage member 6 releases elastic potential energy, the active gear column 51 is driven 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 convex strip 81 toward the side close to the workpiece 9 until the workpiece 9 is clamped.

[0042] Subsequently, the operator slides the rod head tooth plate 72 back into place to engage it with the driving tooth column 51 again, restricting the rotation of the driving tooth column 51. At this point, the main and auxiliary processes of the workpiece 9 can begin.

[0043] After the main and auxiliary processes are completed, the operator pulls out the rod head tooth plate 72 again to release the restriction on the driving tooth column 51. Subsequently, the operator holds the ring on the outer surface of the crank rod and slides the fixed rack 82 towards both sides. At this time, the movement of the fixed rack 82 drives the driven tooth column 52 and the driving tooth column 51 to rotate synchronously.

[0044] Please refer to Figure 10 As shown, during this process, the rotation of the driving tooth column 51 drives the rotation of the driven ratchet column 42. Since the driven ratchet column 42 is restricted by the driving ratchet column 41, and when the spring constant of the torsion spring 62 is significantly greater than that of the telescopic rod 61, when the torsion spring 62 is subjected to an external force, such as the torque generated by the rotation of the driving tooth column 51, the deformation is extremely small and can be approximately regarded as a rigid connection body. At this time, the force generated by the operator sliding the fixed rack 82 will act on the telescopic rod 61 first. This is because the spring constant is small and it is easy to compress, rather than the torsion spring 62, thus realizing the contraction of the telescopic rod 61. The contraction of the telescopic rod 61 can provide the movement space for the whole composed of the torsion spring 62, the driving tooth column 51 and the driven ratchet column 42. As the driving tooth column 51 rotates continuously, the telescopic rod 61 will also be continuously compressed to provide the movement space and continuously make the driven ratchet column 42 and the driving ratchet column 41 approach and move away from each other.

[0045] At this time, the driven ratchet column 42 rotates along the inclined surface of the driving ratchet column 41 and continuously abuts under the elasticity of the telescopic rod 61, while the operator continuously slides the fixed rack 82 until the workpiece 9 can be successfully removed.

[0046] After that, reset the rod head tooth plate 72, then rotate the bridge plate 1, remove the workpiece 9 on the top of the bridge plate 1, and release the restriction of the hydraulic fixture 2 on the workpiece 9. Thus, a complete processing cycle is completed.

[0047] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the said element.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
