Description

Technical Field

[0001] This utility model relates to the field of vehicle processing technology, and specifically to an auxiliary clamping device for vehicle processing workpieces. Background Technology

[0002] Vehicle machining refers to the processing and handling of various parts during vehicle manufacturing or repair to meet the vehicle's design requirements and performance specifications. The engine is a core component of a vehicle, and the machining precision requirements for its parts are extremely high. For example, the engine block, the main body of the engine, requires milling, boring, and other machining processes to ensure the dimensional accuracy and surface roughness of each cylinder, ensuring a good fit and sealing performance of the piston within the cylinder. The crankshaft, a critical component in the engine that bears alternating loads, requires multiple processes such as forging, turning, and grinding to ensure the dimensional accuracy, roundness, and cylindricity of its journals, as well as the surface hardness and roughness, thereby ensuring the engine's power output and stability.

[0003] In the current field of vehicle machining, existing workpiece clamping devices generally have functional limitations, mostly possessing only basic clamping functions and lacking auxiliary clamping capabilities. This deficiency makes the fixture highly susceptible to interference from external forces, irregular workpiece shapes, and other factors during actual workpiece clamping, resulting in numerous instabilities that affect the machining accuracy and efficiency of the workpiece, and cause significant inconvenience to subsequent cutting, grinding, and other processing operations. Therefore, to address the above technical problems, an auxiliary clamping device for vehicle machining workpieces is proposed. Utility Model Content

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] Please see Figure 1 and Figure 2 One embodiment of a vehicle processing workpiece auxiliary clamping device includes a mounting platform 10, a clamping mechanism, and an auxiliary clamping mechanism.

[0020] The clamping mechanism is mounted on the mounting platform 10. The auxiliary clamping mechanism includes a support plate 20, a first spring 201, a clamping seat 202, and a first transmission assembly. The support plate 20 is slidably mounted on the top of the mounting platform 10 in a vertical direction. Multiple sets of first springs 201 are arranged between the support plate 20 and the mounting platform 10. Two sets of through slots 203 are opened opposite each other on the support plate 20. Two sets of clamping seats 202 are slidably mounted opposite each other on the top of the mounting platform 10. The tops of the two sets of clamping seats 202 pass through the two sets of through slots 203 respectively. The first transmission assembly connects the support plate 20 and the two sets of clamping seats 202, and drives the two sets of clamping seats 202 to move closer or further apart when the support plate 20 moves downward or upward.

[0021] In the above embodiment, by placing the workpiece (not shown) on the support plate 20, the weight of the workpiece causes the support plate 20 to move downward and compress the first spring 201. The downward movement of the support plate 20 drives the two sets of clamping seats 202 to move closer to each other via the first transmission component. The relative movement of the two sets of clamping seats 202 can assist in clamping the workpiece on the support plate 20. By relying on the gravity of the workpiece itself to drive the two sets of clamping seats 202 to automatically clamp the workpiece, the auxiliary clamping is convenient, improves the stability of the actual workpiece clamping, avoids affecting the workpiece's processing accuracy and efficiency, and facilitates subsequent processing operations. After processing is completed, the actual clamping is canceled, and then the workpiece is moved upward. At this time, the gravity of the workpiece on the support plate 20 disappears, and the reaction force of the first spring 201 causes the support plate 20 to move upward. The upward movement of the support plate 20 drives the two sets of clamping seats 202 to move away from each other and reset via the first transmission component, thereby facilitating the auxiliary clamping of the workpiece again.

[0022] Specifically, the top of the mounting platform 10 has two sets of T-slots 105 facing each other, and the bottom ends of the two sets of clamping seats 202 are slidably disposed in the two sets of T-slots 105 respectively. This ensures the stability of the sliding of the clamping seats 202.

[0023] Specifically, the top of the mounting platform 10 is provided with multiple sets of connecting posts 101. The support plate 20 is slidably fitted onto the multiple sets of connecting posts 101 in the vertical direction and is limited by the limiting knob 102. Each set of connecting posts 101 is fitted with a first spring 201, and both ends of the first spring 201 abut against the top surface of the mounting platform 10 and the bottom surface of the support plate 20. By setting the connecting posts 101 to cooperate with the support plate 20, the stability of the sliding of the support plate 20 is ensured. The first spring 201 is fitted onto the connecting posts 101, and the connecting posts 101 can guide the extension and retraction of the first spring 201, which can improve the service life of the first spring 201. Furthermore, the support plate 20 and the first spring 201 can be removed by disassembling the limiting knob 102, which is convenient for replacing the first spring 201 if it fails.

[0024] Please refer to the following: Figure 3 Specifically, the first transmission component includes a shift shaft 204; two sets of through slots 203 each have an inclined shift groove 205 on both sides, with the end of the shift groove 205 in the two sets of through slots 203 being the high end; two sets of clamping seats 202 each have a shift shaft 204 on both sides, and the shift shaft 204 is slidably disposed within the shift groove 205. When the support plate 20 moves downward, the shift groove 205 in the two sets of through slots 203 presses against the shift shaft 204, causing the shift shaft 204 to move towards the high end of the shift groove 205, thereby driving the two sets of clamping seats 202 to move relatively closer together. Conversely, when the support plate 20 moves upward, the shift groove 205 presses against the shift shaft 204, causing the shift shaft 204 to move towards the low end of the shift groove 205, thereby driving the two sets of clamping seats 202 to move relatively away from each other, making it convenient to drive the two sets of clamping seats 202 to move relatively closer or further apart.

[0025] Please see Figure 2 In one embodiment, a placement plate 206 is detachably mounted on the top of the support plate 20, and the top surface of the placement plate 206 is a smooth plane. Specifically, the support plate 20 is fixed to the placement plate 206 by bolts. By providing the placement plate 206, the friction between the workpiece and the support plate 20 can be reduced, thereby facilitating the movement of the workpiece when one set of clamping seats 202 contacts the workpiece, so that the two sets of clamping seats 202 can clamp the workpiece, which facilitates the alignment of the workpiece. Furthermore, the placement plate 206 is detachable, making it easy to replace.

[0026] Please see Figure 1 , Figure 2 and Figure 4 In one embodiment, the clamping mechanism includes a mounting base 30, a screw 301, and a clamping plate 302; the top of the mounting platform 10 is provided with mounting bases 30 located on both sides of the support plate 20, and screws 301 are threadedly connected to both sets of mounting bases 30, and clamping plates 302 are rotatably provided on the opposite ends of both sets of screws 301.

[0027] In the above embodiments, after the two sets of clamping seats 202 assist in clamping the workpiece, the two sets of screws 301 are rotated respectively to drive the two sets of clamping plates 302 to move closer to each other and contact the workpiece, so that the workpiece can be actually clamped. The actual clamping operation is convenient.

[0028] Furthermore, handwheels 306 are coaxially mounted on the opposite ends of both sets of screws 301 to facilitate the rotation of the screws 301.

[0029] Please refer to the following: Figure 5 In one embodiment, the clamping mechanism further includes a second transmission component and a fixing component; a limiting groove 103 is provided at the top of the mounting platform 10, and the bottom ends of the two sets of mounting seats 30 are slidably disposed in the limiting groove 103. The second transmission component is disposed in the limiting groove 103 and connects the two sets of mounting seats 30, so as to drive the other set of mounting seats 30 to slide in the opposite direction when one set of mounting seats 30 slides. The fixing component is disposed on one set of mounting seats 30 and is used to fix or contact fix the mounting seat 30.

[0030] In the above embodiments, the mounting base 30 is fixed by driving the fixing component, and then one set of mounting bases 30 is slid and the other set of mounting bases 30 is driven to move in the opposite direction by the second transmission component. This makes it easy to drive the two sets of mounting bases 30 to move closer or further apart, thereby facilitating the quick adjustment of the initial distance between the two sets of clamping plates 302 according to the size of the workpiece being processed. This is suitable for clamping and processing various workpieces and improves the practicality of the device.

[0031] Specifically, the second transmission component includes a rack 303 and a gear 304. Two sets of mounting seats 30 are each provided with a rack 303. The gear 304 is rotatably mounted within the limiting groove 103, located between the two sets of racks 303, and meshes with both sets of racks 303. When one set of mounting seats 30 slides, it drives the rack 303 to move and drives the gear 304 to rotate. The rotation of the gear 304 meshes with the other set of racks 303, driving the other set of racks 303 to move the other set of mounting seats 30 in the opposite direction, facilitating the relative movement of the two sets of mounting seats 30 closer or further apart.

[0032] Specifically, the fixing component includes a pin 40; a set of mounting bases 30 is provided with a fixing base 305, and the pin 40 is vertically slidably disposed in the fixing base 305. The top of the mounting platform 10 has multiple sets of fixing holes 104 spaced apart along the sliding direction of the mounting base 30, and the bottom end of the pin 40 can pass through any of the fixing holes 104. By moving the pin 40 upward to disengage it from the currently mating fixing hole 104, the fixing of the mounting base 30 can be released. At this time, the mounting base 30 can be slid to adjust the initial distance between the two sets of clamping plates 302. When the mounting base 30 is adjusted to a suitable position, moving the pin 40 downward to pass through the currently mating fixing hole 104 can fix the mounting base 30. Fixing and releasing the mounting base 30 is convenient.

[0033] Based on the above embodiments, the fixing component further includes a second spring 401; a limiting plate 402 is provided on the pin 40, and the second spring 401 is sleeved on the pin 40, with its two ends abutting against the top of the limiting plate 402 and the bottom of the fixing base 305, respectively. By providing the second spring 401, the stability of the pin 40 passing through the fixing hole 104 can be improved.

[0034] The specific implementation of the above-mentioned auxiliary clamping device for vehicle processing workpieces is as follows: By placing the workpiece on the support plate 20, the weight of the workpiece causes the support plate 20 to move downwards and compress the first spring 201. This downward movement of the support plate 20 causes the grooves 205 in the two sets of through slots 203 to press against the dial shaft 204, thus moving the dial shaft 204 towards the higher end of the groove 205. This movement, in turn, drives the two sets of clamping seats 202 to move closer together. This relative movement of the two sets of clamping seats 202 provides auxiliary clamping of the workpiece on the support plate 20. By relying on the workpiece's own weight to drive the two sets of clamping seats 202 to automatically clamp the workpiece, auxiliary clamping is convenient, improving the stability of the actual workpiece clamping, avoiding impact on the workpiece's machining accuracy and efficiency, and facilitating subsequent machining operations. Then, rotating the two sets of screws 301 respectively drives the two sets of clamping plates 302 to move closer together and contact the workpiece, thus performing actual clamping of the workpiece. The actual clamping operation is convenient.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
