Description

Technical Field

[0001] This utility model relates to the field of motorcycle processing and positioning, specifically to a support clamping device for irregularly shaped parts. Background Technology

[0002] When machining irregularly shaped parts such as motorcycle housings, it involves processing the sides, top surface, and internal oil passages of the product. Therefore, rotary clamping fixtures are commonly used to clamp the product to facilitate machining of different parts. For example, a prior art flipping fixture (publication number: CN213730592U; application date: 2020-09-29) clamps the product using a four-axis rotary table and can achieve 360° rotation without disassembling the part to meet the machining requirements of different surfaces. The applicant has encountered the following problems in practical application:

[0003] 1. Due to fluctuations in the hole spacing and unstable hole diameter during product processing, ordinary locating pins cannot be used to accommodate the fluctuations in product hole diameter and hole spacing.

[0004] 2. If a screw is used to support the product, when the screw extends too far, the screw's rigidity is insufficient, resulting in an unsatisfactory support effect, which in turn affects the product's clamping stability and processing results. Utility Model Content

[0005] The present invention aims to provide a clamping device for supporting irregularly shaped parts, so as to solve the problem that in the prior art, when the screw is used to support the product, the rigidity is insufficient and the support effect is affected when the screw is screwed out too much.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The irregular part supports a clamping device, including a four-axis and a rotary tailstock. A main board is connected between the four-axis and the rotary tailstock. The main board is equipped with a positioning component and a clamping component. The clamping component includes at least two clamping cylinders. The main board is fixed with a support base with the same number of clamping cylinders. The clamping cylinders are installed on the support bases one by one. The support bases are used to support the product, and the clamping cylinders are used to clamp the product.

[0008] Preferably, as an improvement, the support base includes a clamping cylinder base and a support block, wherein the clamping cylinder base and the support block are integrally formed.

[0009] Preferably, as an improvement, the support block is frustum-shaped.

[0010] Preferably, as an improvement, the support block has a clearance notch for avoiding products.

[0011] Preferably, as an improvement, the number of clamping cylinders is three, and the three clamping cylinders are distributed in a triangle.

[0012] Preferably, as an improvement, the positioning component includes an X floating positioning pin, a Y floating positioning pin, an X limiter, and a Y limiter.

[0013] Preferably, as an improvement, the four-axis connection includes a four-axis connecting plate, which is connected to the main board. An oil distribution block is fixed on the four-axis connecting plate, and an oil distributor is connected to the oil distribution block. The oil distribution block has an inlet oil distribution channel and an outlet oil distribution channel. The main board has an inlet oil channel and an outlet oil channel. The oil inlet of the pressing cylinder is connected to the inlet oil distribution channel through the inlet oil channel, and the oil outlet of the pressing cylinder is connected to the outlet oil distribution channel through the outlet oil channel.

[0014] Preferably, as an improvement, the oil inlet channel and the oil outlet channel are arranged side by side along the Y direction within the oil distribution block, and the oil inlet channel and the oil outlet channel are arranged side by side along the Z direction within the main board.

[0015] Preferably, as an improvement, it also includes a base, with a four-axis base plate connected to the bottom of the four-axis shaft and a tailstock base plate connected to the bottom of the slewing tailstock. The four-axis base plate and the slewing tailstock are detachably mounted on the base.

[0016] Preferably, as an improvement, a dovetail groove is provided on the base along the X direction, and the four-axis base plate and the tailstock base plate are detachably connected in the dovetail groove by bolts.

[0017] The principles and beneficial effects of this solution are as follows:

[0018] 1. The product is placed on the motherboard and positioned using X-floating positioning pins, Y-floating positioning pins, X-limiting clips, and Y-limiting clips. It is supported by support blocks on the support base and clamped by a clamping cylinder, thus completing the product clamping and processing. The four-axis spindle and rotary tailstock drive the product on the motherboard to rotate, allowing for the processing of different parts of the product to meet various processing requirements.

[0019] This solution uses floating positioning pins inserted into the product for positioning. Compared with ordinary positioning pins, floating positioning pins can adapt to fluctuations in the product's aperture and hole spacing through their floating properties, thereby better positioning the product and improving the stability of product positioning.

[0020] This solution uses support blocks to support the product. Compared to screw supports, it avoids the problem of insufficient rigidity caused by excessive screw extension, ensuring the rigidity of the support block and thus guaranteeing the product's support effectiveness. Furthermore, the support block and the clamping cylinder base are integrally molded into a support base, serving the dual functions of clamping cylinder installation and product support. This not only facilitates manufacturing but also further enhances the rigidity of the support block. Moreover, the frustum-shaped support block, with its smaller top accommodating the product and clamping cylinder for easy clamping, and its larger base providing sufficient support and stability, further ensures the support block's effectiveness.

[0021] 2. The product is subjected to three clamping cylinders arranged in a triangle, which ensures balanced force distribution and good support stability.

[0022] 3. The oil for the clamping cylinder is delivered to the oil distribution block via the oil distributor, and then from the oil distribution block to the oil inlet and outlet channels, finally entering the clamping cylinder. The oil inlet and outlet channels are located inside the main board. Compared with external oil pipes for delivering oil to the clamping cylinder, this avoids the problems of oil pipe entanglement, pulling, and interference with processing during the rotation of the main board, and also improves the aesthetics of the equipment.

[0023] In this design, the oil inlet and outlet channels are arranged side-by-side along the Y-axis, which reduces the thickness (X-axis length) of the oil distribution block. The oil inlet and outlet channels are also arranged side-by-side along the Z-axis within the main board. Compared to arranging them side-by-side along the X-axis, this reduces the X-axis length of the main board, thereby reducing its size and weight, and ultimately lowering costs. Furthermore, arranging the oil inlet and outlet channels side-by-side along the Z-axis within the main board avoids interference with the oil passages along the X-axis that connect to another clamping cylinder, facilitating oil passage layout and machining.

[0024] 4. The four-axis and the rotary tailstock are detachably mounted on the base via the four-axis base plate and the tailstock base plate, respectively. In actual use, the distance between the four-axis and the rotary tailstock can be adjusted as needed to install motherboards of different sizes to adapt to the processing of products of different sizes, thereby improving the versatility and flexibility of the equipment.

[0032] Example:

[0033] like Figure 1 and Figure 2 As shown, the non-standard part supports clamping device, including a four-axis 2, a rotary tailstock 3, and a base 1. The bottom of the four-axis 2 is bolted to a four-axis base plate 21, and the bottom of the rotary tailstock 3 is bolted to a tailstock base plate 31. The four-axis base plate 21 and the rotary tailstock 3 are detachably mounted on the base 1. Specifically, a dovetail groove 11 is opened on the base 1 along the X direction, and the four-axis base plate 21 and the tailstock base plate 31 are detachably connected in the dovetail groove 11 by bolts.

[0034] It also includes a motherboard 5, which is connected to the four-axis 2 and the rotary tailstock 3. Specifically, the four-axis 2 is bolted to the right side of the four-axis connecting plate 22, and the rotary tailstock 3 is bolted to the left side of the tailstock connecting plate 32. The two ends of the motherboard 5 are connected to the four-axis connecting plate 22 and the tailstock connecting plate 32 by bolts.

[0035] The motherboard 5 is equipped with a positioning component and a clamping component. The positioning component includes an X floating positioning pin 82, a Y floating positioning pin 83, an X limit card 8, and a Y limit card 81. The X floating positioning pin 82, the Y floating positioning pin 83, the X limit card 8, and the Y limit card 81 are fixed to the motherboard 5 by bolts. The X limit card 8 and the Y limit card 81 are U-shaped limit cards.

[0036] The clamping assembly includes at least two clamping cylinders 61, and in this embodiment, three clamping cylinders 61 are arranged in a triangular pattern. Each clamping cylinder 61 is a lever-type hydraulic cylinder. The main board 5 has a number of support seats 6 equal to the number of clamping cylinders 61. Each clamping cylinder 61 is mounted one-to-one on a support seat 6. Specifically, in conjunction with… Figure 5 As shown, the support base 6 includes an integrally formed clamping cylinder base 63 and a support block 62, with the clamping cylinder 61 bolted to the clamping cylinder base 63. In this embodiment, the support block 62 is a frustum-shaped support block 62, one of which has a clearance notch 64 for avoiding the product 4.

[0037] Combination Figure 3 and Figure 4As shown, an oil distribution block 7 is bolted to the four-axis connecting plate 22. The oil distribution block 7 is connected to an oil distributor. An oil inlet channel 71 and an oil outlet channel 72 are arranged side-by-side along the Y direction inside the oil distribution block 7, with the oil inlet channel 71 on the outer side and the oil outlet channel 72 on the inner side. An oil inlet channel 51 and an oil outlet channel 52 are arranged side-by-side along the Z direction inside the main plate 5, with the oil inlet channel 51 on top and the oil outlet channel 52 on the bottom. The oil inlets of the three clamping cylinders 61 are connected to the oil inlet channel 71 through the three oil inlet channels 51, and their oil outlets are connected to the oil outlet channel 72 through the oil outlet channels 52. A spare flow channel 73 is reserved inside the oil distribution block 7. For example, the spare flow channel 73 can be used as a vent for airtightness testing. When it is necessary to test whether the product 4 is properly clamped, the spare flow channel 73 can be connected to the airtightness testing device of the machine tool for airtightness testing.

[0038] In practical application, product 4 is placed on the main board 5. X floating positioning pin 82 and Y floating positioning pin 83 are inserted into the positioning holes of product 4, and X limit clip 8 and Y limit clip 81 are engaged with the contour of product 4, thus initially limiting product 4. After product 4 is in place, its edges rest on three support blocks 62. Oil enters from the oil inlet 51 into the clamping cylinder 61, which clamps the edges of product 4, thus completing the positioning of product 4. After positioning, product 4 can be processed. The main board 5 is rotated via the four-axis 2 and the rotary tailstock 3, which in turn rotates product 4, allowing for the processing of different surfaces of product 4.
