Description

Technical Field

[0001] This utility model relates to the field of cylinder head processing technology, and more specifically to a processing clamping device compatible with different cylinder heads. Background Technology

[0002] Cylinder head machining refers to a series of machining, assembly and inspection activities performed on the engine cylinder head to achieve the specified geometric dimensions, tolerances, surface roughness and functional requirements. The cylinder head is a key component of the engine, bearing the intake manifold, exhaust manifold, spark plug holes, intake and exhaust manifold mating surfaces, etc. Therefore, its machining requires high precision, good surface quality and stable geometry. Chinese Patent CN214722406U discloses a clamping device for machining engine cylinder heads, relating to the field of clamping device technology. It includes a fixed frame with a limiting block fixedly installed on the top of the inner wall of the fixed frame. A threaded rod is threadedly connected to the inside of the limiting block. Control rods B are movably connected to both sides of the limiting block. A control rod A is movably connected to the other end of each control rod B. A clamping block is movably connected to the other end of each control rod A. The two linkage rods are movably connected via a linkage rod. When the control wheel rotates forward, it controls an H-shaped pulley C to drive an H-shaped gear. The H-shaped gear meshes with the H-shaped pulley B, controlling the rotation of the H-shaped pulley A. The rotation of the H-shaped pulley A meshes with the threaded rod, causing it to rise. The rising of the threaded rod controls the two clamping blocks to clamp and fix the cylinder head. This allows for clamping and fixing of both sides of the cylinder head, and it can fix cylinder heads of different widths, while providing a larger operating space during clamping.

[0003] Based on existing solutions and actual production and processing applications, existing cylinder head machining clamping devices are only applicable to cylinder heads of specific models or structures, making them incompatible with cylinder heads of the same series or different models. This results in difficulties in quickly switching between cylinder heads of different specifications, thereby reducing overall flexibility. Therefore, we propose a machining clamping device that is compatible with different cylinder heads to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a machining clamping device that is compatible with different cylinder heads, so as to solve the problem mentioned in the background art that the current cylinder head machining clamping devices can only be applied to cylinder heads of specific models or structures, thus making them incompatible with cylinder heads of the same series or different models.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a machining clamping device compatible with different cylinder heads, including a machining table: The top of the processing table has a first through slot at both the left and right ends, and a first clamping plate is slidably connected in the slot. The bottom of the processing table has a sliding rod fixedly installed at both the front and rear ends, and the rod of the sliding rod is slidably connected to the lower end of the first clamping plate. The bottom of the processing table is provided with a clamping assembly, the frame of the first clamping plate is provided with a fixing assembly, and the top of the processing table is provided with a pushing assembly.

[0006] Preferably, the clamping assembly includes a rotating rod, a hinge plate, a guide rod, a gear, a rack, and an electric push rod. The rotating rod is rotatably connected to the middle position of the bottom of the processing table. The lower end of the rotating rod is fixedly installed with a hinge plate, and both ends of the hinge plate are rotatably connected with guide rods. The upper end of the rotating rod is fixedly installed with a gear. The left end of the bottom of the processing table is slidably connected with a rack, and the rack and gear mesh with each other. The rear end of the bottom of the processing table is fixedly installed with an electric push rod, and the output end of the electric push rod is connected to the rack.

[0007] Preferably, the front guide rod and the rear guide rod in the hinge plate are arranged in an alternating manner, the guide rods are arranged in an inclined manner, and one end of the guide rod is rotatably connected to the middle position of the lower end of the first clamping plate.

[0008] Preferably, the fixing component includes a second through slot, a second clamping plate, a bidirectional threaded rod, and a motor. The first clamping plate has a second through slot on its frame. The second clamping plate is slidably connected to both the front and rear ends of the second through slot. The side wall of the first clamping plate is rotatably connected to the bidirectional threaded rod. The motor is fixedly installed at the rear end of the side wall of the first clamping plate frame.

[0009] Preferably, the rear end of the bidirectional threaded rod is connected to the output end of the motor, and the rod body is connected to the second clamping plate by threads.

[0010] Preferably, the pushing assembly includes a chute, a placement plate, and a lead screw, and the chute is provided at the middle position of the top of the processing table. The placement plate is slidably connected in the chute, and the lead screw is rotatably connected in the chute. The rod of the lead screw is connected to the placement plate by a thread.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects: the machining clamping device that is compatible with different cylinder heads can support the machining of various cylinder heads by moving the first clamping plate, thereby realizing the clamping of cylinder heads of the same series or different cylinder heads. At the same time, the movement of the second clamping plate ensures that the reference remains stable throughout the machining process, thereby avoiding batch dimensional deviations caused by workpiece displacement. Then, the movement of the placement plate can push the cylinder head to the position required for machining, thereby achieving rapid positioning on the same fixture and improving the consistency of machining. 1. By meshing the rack and gear, the output end of the electric push rod drives the rack to slide at the bottom of the machining table, thereby driving the rotating rod to rotate and simultaneously driving the hinge plate to rotate. Because both ends of the hinge plate are rotatably connected to guide rods, and one end of the guide rod is inclined and rotatably connected to the first clamping plate, the two sets of first clamping plates can be driven to slide on the groove of the first through slot and the rod of the sliding rod, so that the two sets of first clamping plates can move closer or further apart, thereby clamping the cylinder head. The movement of the first clamping plates can support the processing of various cylinder heads, thereby realizing the clamping of the same series or different cylinder heads, thus improving the utilization rate of the machining center. 2. The output end of the motor is connected to the rear end of the bidirectional threaded rod, and the rod body is connected to the second clamping plate through threads. The operation of the motor can drive the bidirectional threaded rod to rotate, and drive the second clamping plate to slide in the groove of the second through slot. This allows the two sets of second clamping plates to move closer or further apart. The movement of the second clamping plates can fix the cylinder head. The movement of the second clamping plates ensures that the reference remains stable throughout the entire processing, thereby avoiding batch dimensional deviations caused by workpiece displacement and improving processing accuracy. 3. The lead screw is connected to the placement plate by a thread. Rotating the lead screw causes the placement plate to slide within the groove. The movement of the placement plate can push the workpiece to the designated position and move the cylinder head to the required machining position. This allows for rapid positioning on the same fixture, thereby improving machining consistency. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figures 1-6 The present invention provides the following technical solution: A machining clamping device compatible with different cylinder heads includes a machining table 1, a first through groove 2, a first clamping plate 3, a sliding rod 4, a rotating rod 5, a hinge plate 6, a guide rod 7, a gear 8, a rack 9, an electric push rod 10, a second through groove 11, a second clamping plate 12, a bidirectional threaded rod 13, a motor 14, a slide groove 15, a placement plate 16, and a lead screw 17. like Figure 1 , Figure 3 and Figure 4 As shown, when machining the cylinder head, a slide groove 15 is provided at the middle position of the top of the machining table 1, and a placement plate 16 is slidably connected in the slide groove 15. At the same time, a lead screw 17 is rotatably connected in the slide groove 15, and the rod of the lead screw 17 is connected to the placement plate 16 by threads, so that the cylinder head can be placed on the top of the placement plate 16. Then, the lead screw 17 is rotated, and when the lead screw 17 is rotated, the lead screw 17 drives the placement plate 16 to slide in the slide groove 15. Thus, the cylinder head can be moved to the designated position by the movement of the placement plate 16. The cylinder head can be moved to the position required for machining by the movement of the placement plate 16, so that rapid positioning can be achieved on the same fixture. like Figure 1 , Figure 2 , Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6As shown, after the placement plate 16 pushes the cylinder head to the designated position, the top of the processing table 1 has first through slots 2 at both the left and right ends, and a first clamping plate 3 is slidably connected to the inside of the first through slots 2. Sliding rods 4 are fixedly installed at both the front and rear ends of the bottom of the processing table 1, and the rods of the sliding rods 4 are slidably connected to the lower end of the first clamping plate 3. A rotating rod 5 is rotatably connected to the middle position of the bottom of the processing table 1, and a hinge plate 6 is fixedly installed at the lower end of the rotating rod 5. Guide rods 7 are rotatably connected to both the front and rear ends of the hinge plate 6, with the front and rear guide rods 7 of the hinge plate 6 arranged in an alternating state. The guide rods 7 are also inclined, and one end of the guide rod 7 is rotatably connected to the middle position of the lower end of the first clamping plate 3. A gear 8 is fixedly installed at the upper end of the rotating rod 5, and a rack 9 is slidably connected to the left end of the bottom of the processing table 1. Furthermore, an electric push rod 10 is fixedly installed at the rear end of the bottom of the processing table 1. The output end of the electric push rod 10 is connected to the rack 9, so that the electric push rod 10 can be controlled by the controller. When the electric push rod 10 is running, it can drive the rack 9 to slide at the bottom of the processing table 1. Because the rack 9 and the gear 8 mesh with each other, when the rack 9 slides, it can drive the rotating rod 5 to rotate through the gear 8. When the rotating rod 5 rotates, it can drive the hinge plate 6 to rotate synchronously. When the hinge plate 6 rotates, it can drive the first clamping plate 3 to slide on the groove of the first through groove 2 and the rod of the sliding rod 4 through the guide rod 7, so that the two sets of first clamping plates 3 are close to each other or far away from each other. Thus, the movement of the first clamping plate 3 can be adjusted according to the size of the cylinder head, and the movement of the two sets of first clamping plates 3 can clamp the cylinder head. The movement of the first clamping plate 3 can support the processing of various cylinder heads, thereby realizing the clamping of the same series or different cylinder heads. like Figure 1 , Figure 2 , Figure 3 Appendix Figure 4 As shown, after the cylinder head is clamped by the first clamping plate 3, the motor 14 can be controlled to rotate forward and backward by the controller. Since the frame of the first clamping plate 3 is provided with a second through groove 11, and the front and rear ends of the second through groove 11 are slidably connected to the second clamping plate 12, and the bidirectional threaded rod 13 is rotatably connected to the side wall of the first clamping plate 3, and the rod of the bidirectional threaded rod 13 is connected to the second clamping plate 12 by threads. At the same time, the rear end of the bidirectional threaded rod 13 is connected to the output end of the motor 14. When the motor 14 is running, it can drive the bidirectional threaded rod 13 to rotate. When the bidirectional threaded rod 13 rotates, it can drive the second clamping plate 12 to slide in the groove of the second through groove 11, so that the two sets of second clamping plates 12 move closer to the cylinder head, thereby fixing the cylinder head. The movement of the second clamping plate 12 ensures that the reference remains stable throughout the entire processing process, thereby avoiding batch dimensional deviations caused by workpiece displacement. The above completes a series of operations for the machining clamping device compatible with different cylinder heads.
