Description

Technical Field

[0001] The invention belongs to the technical field of multifunctional fixtures, in particular to a multifunctional fixture for five valve bodies. Background Art

[0002] Five valve bodies are core precision components in the fields of fluid control, pneumatic braking, industrial hydraulics and the like, and are widely used in various complete sets of equipment such as engineering machinery, automobile braking, automatic control and the like. Such valve body members have special-shaped and complex structures, with multiple groups of fluid channels, processed end faces and precision hole systems distributed all over the body. The overall processing procedures are numerous, and the dimensional accuracy, position度 and coaxiality requirements of each processed surface are strict, which places extremely high standards on the positioning reliability, clamping adaptability and structural stability of tooling fixtures. In the large-scale precision processing of five valve bodies, as a core tooling, the fixture directly determines the processing accuracy and finished product consistency of each end face and hole system of the workpiece, and is a key equipment for guaranteeing product processing quality and production efficiency.

[0003] At present, most of the tooling used for processing five valve bodies in the industry are fixed special fixtures or ordinary general vises, with solidified structural forms and single clamping modes, and have obvious technical shortcomings. They cannot adapt to the multi-faceted differentiated precision processing requirements of five valve bodies, and are difficult to meet the requirements of modern flexible production. Traditional fixtures have single clamping function and extremely poor adaptability to processed surfaces. Most existing fixtures adopt fixed single-point and single-angle clamping structures, which can only press and fix a single reference surface of the five valve body, and can only complete milling, drilling and other process operations on the corresponding single processed surface. For processed surfaces of different orientations and different angles such as the top surface, side surface, inclined surface and end surface of the five valve body, compatible clamping and positioning cannot be achieved. When processing different workstations and different processed surfaces, it is necessary to frequently disassemble and replace the fixture and re-align the clamping. The model and die changing process is cumbersome, which greatly reduces the effective processing time of the machine tool and seriously restricts the overall production rhythm. Therefore, it is necessary to improve it. Summary of the Invention

[0018] The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] As shown in Figures 1 to 11 , the present invention provides a multifunctional clamp for five-valve bodies, comprising a bottom plate 1, wherein a top surface of the bottom plate 1 is fixedly connected with a first cross beam 2 and a second cross beam 3, the first cross beam 2 and the second cross beam 3 are spliced into an "丄"-shaped structure, oil cylinder backing plates 14 are installed on both sides of a top of the bottom plate 1, and a top of each of the oil cylinder backing plates 14 is respectively and fixedly connected with a first oil cylinder 4 and a second oil cylinder 5; One end of the first oil cylinder 4 is fixedly connected with a long push rod 6, one end of the long push rod 6 away from the first oil cylinder 4 is fixedly connected with an ejector block flange 7, and one end of the ejector block flange 7 away from the long push rod 6 is fixedly installed with a long push rod ejector block 8; one end of the second oil cylinder 5 is fixedly connected with a short push rod 9, one end of the short push rod 9 is fixedly installed with a short push rod ejector block 10 through the ejector block flange 7, a plurality of stainless steel pipes 12 are arranged at upper ends of the first oil cylinder 4 and the second oil cylinder 5, and the plurality of stainless steel pipes 12 are connected by ferrule fittings 11.

[0020] By adopting the above solution: the "丄"-shaped support base body formed by the first cross beam 2 and the second cross beam 3 can stably carry various positioning cushion blocks and valve body workpieces, and realizes stable installation and positioning of the overall structure in cooperation with the bottom plate 1; the oil cylinder backing plates 14 are used to elevate and limit the first oil cylinder 4 and the second oil cylinder 5, so as to avoid wear and stress deformation caused by direct attachment of the oil cylinders to the bottom plate 1, and improve the operation stability of the oil cylinders; The first hydraulic cylinder 4 drives the long push rod 6 and the second hydraulic cylinder 5 drives the short push rod 9, which in turn drive the long push rod top block 8 and the short push rod top block 10 to achieve bidirectional synchronous clamping action. With the help of multiple sets of stainless steel pipes 12 connected by the ferrule connector 11, the hydraulic oil circuit can achieve stable oil delivery and sealing without oil leakage, ensuring continuous and stable clamping power, and providing reliable power support and structural foundation for subsequent valve body clamping operations with multiple postures and multiple machining surfaces.

[0021] A workpiece pad 13 is installed on one side of the top of the base plate 1, and the top of the workpiece pad 13 is used to place the five valve bodies.

[0022] The above solution is adopted: by setting a workpiece pad 13 on the top of the base plate 1, the five-valve body workpiece can be stably supported at the bottom, avoiding direct contact between the valve body workpiece and the hard base plate 1 to prevent collisions and scratches, effectively protecting the workpiece blank surface and the machining reference surface; at the same time, the workpiece pad 13 can realize the quick positioning and placement of the workpiece, raise the workpiece machining position, avoid the base plate 1 from interfering with the tool machining path, improve the clamping convenience and machining safety, and adapt to the clamping and machining needs of the five-valve body in the basic postures such as conventional flat and side-lying positions.

[0023] Two conical grooves 27 are symmetrically arranged on both sides of the lower end of the short push rod top block 10, and a filter disc 28 is fixedly connected to the short push rod top block 10 at one end of the two conical grooves 27.

[0024] The above solution involves symmetrically opening conical grooves 27 at the lower end of the short push rod top block 10, and using a filter disc 28 fixed to the end. This allows for the initial interception and diversion of iron filings, dust, and cutting fluid generated during valve body processing. The conical surface structure of the conical groove 27 improves the efficiency of impurity adsorption and diversion, while the filter disc 28 effectively filters large iron filings and impurities, preventing impurities from accumulating on the workpiece clamping contact surface and the processing surface. This prevents impurities from affecting clamping accuracy and scratching the workpiece surface, while ensuring the smooth flow of subsequent negative pressure adsorption pipelines, effectively improving the cleanliness of workpiece processing and clamping positioning accuracy.

[0025] A first pipe 29 is fixedly connected to the end of the conical groove 27 away from the filter plate 28. The tops of the two first pipes 29 are connected to a second pipe 30. A negative pressure machine 31 is fixedly connected to the end of the second pipe 30 away from the first pipe 29. The negative pressure unit 31 is fixed to the side wall of the base plate 1.

[0026] The above solution is adopted: negative pressure suction is generated by the operation of negative pressure machine 31, and the suction is split into two sets of first pipes 29 through the second pipe 30. Together with the conical groove 27, it forms an all-round negative pressure adsorption structure, which can quickly adsorb and collect iron filings, dust and cutting fluid generated during the processing in real time, and remove debris from the workpiece processing surface and clamping contact surface. The negative pressure machine 31 is fixed to the side wall of the base plate 1, which does not occupy the workpiece clamping and processing space. The structure is compact and can realize processing and chip removal simultaneously, avoiding workpiece clamping deviation and processing surface defects caused by debris residue, and continuously ensuring the accuracy of multi-face processing and the surface quality of the workpiece.

[0027] The second crossbeam 3 divides the area above the base plate 1 into two clamping zones, and the structures in the two clamping zones are identical.

[0028] The above solution uses the second crossbeam 3 to separate two sets of independent clamping areas with identical structures, enabling synchronous clamping operations at two stations. The two clamping areas do not interfere with each other and work independently, allowing for the simultaneous clamping and fixing of multiple sets of five-valve body workpieces and multi-face machining. This significantly improves the clamping capacity and machining efficiency of the fixture, adapting to the needs of batch production. At the same time, the symmetrical structure ensures consistent clamping accuracy on both sides, effectively reducing machining errors in batch workpieces and improving the overall machining consistency of the product.

[0029] The top of the workpiece pad 13 is occupied by a five-valve body blank side plate 15, which is held by a long push rod top block 8 and a short push rod top block 10. There are twenty five-valve body blank side plates 15.

[0030] The above solution involves using a workpiece pad 13 to support the side-mounted five-valve body blank 15 at the bottom, and coordinating with the long push rod top block 8 and the short push rod top block 10 for bidirectional clamping and positioning. This allows for the simultaneous side-mounting and clamping of twenty five-valve body blanks. It is suitable for batch processing of the side, side end hole system, and side end face of the five-valve body, allowing for the clamping of multiple workpieces at once without frequent material changes or repeated clamping. This greatly reduces clamping auxiliary time, significantly improves the batch production efficiency of the side processing of the five-valve body, and ensures uniform clamping force, effectively guaranteeing the consistent processing accuracy of the side processing of multiple workpieces.

[0031] The long push rod top block 8 and the short push rod top block 10 internally hold multiple five-valve body blanks horizontally placed 16 and five-valve body horizontal pads 17, with the five-valve body horizontal pads 17 attached to the side wall of the first crossbeam 2. When placing the five-valve body blank horizontally 16 and the five-valve body horizontal pad 17, a 44mm thick workpiece pad is used.

[0032] The above solution is adopted: by adding a five-valve body horizontal pad 17 and positioning it against the side wall of the first crossbeam 2, and cooperating with a 44-thick workpiece pad to adapt to the horizontal installation height, it can accurately adapt to the clamping reference requirements of the five-valve body blank horizontally 16, and accurately raise, limit and support the valve body in the horizontal position. With the long push rod top block 8 and the short push rod top block 10 clamping in both directions, the five valve body workpiece in a horizontal position can be stably fixed. It is effectively adapted to the precision machining of the valve body upper end face, horizontal hole system, horizontal groove and other horizontal machining surfaces. The pad block can eliminate the clamping gap and avoid the workpiece from shifting laterally, which greatly improves the stability and accuracy of multi-face machining in a horizontal position.

[0033] The internal clamps of the long push rod top block 8 and the short push rod top block 10 hold multiple five-valve bodies flat 18 and five-valve body flat pads 19. When placing the five valve bodies flat 18 and the five valve body flat pad 19, a 64mm thick workpiece pad is used; The above solution is adopted: by using a 64mm thick workpiece pad in conjunction with a five-valve body flat pad 19 to adapt to the clamping condition of the five-valve body lying flat 18, compared with conventional pads, it can accurately match the machining reference height of the flat valve body, effectively raising the workpiece and avoiding tool interference. The five-valve-body flat pad 19 provides stable support and uniform force to the flat valve body. Combined with the bidirectional top block clamping structure, it can firmly fix the flat five-valve-body workpiece. It is perfectly adapted to milling, drilling and tapping operations on the flat machining surfaces such as the top surface, plane and upper precision hole system of the valve body. The clamping is stable and without shaking, which effectively improves the flatness and positional accuracy of the valve body plane machining.

[0034] The internal clamps of the long push rod top block 8 and the short push rod top block 10 hold the five valve body inclined placement 20, the five valve body inclined pad block A21, the five valve body inclined pad block B22, the five valve body push clamp block 23, and the five valve body 60-degree positioning part 24. After the workpiece pad 13 is removed, the 60-degree positioning piece 24 of the five-valve body is fixed to the first crossbeam 2 and the second crossbeam 3 with bolts. The five-valve body inclined pad A21 and the five-valve body inclined pad B22 are placed on both sides of the five-valve body inclined 20. When the first oil cylinder 4 and the second oil cylinder 5 push the long push rod top block 8 and the short push rod top block 10 to move respectively, the five-valve body placed between the five-valve body push clamping block 23 and the five-valve body 60-degree positioning piece 24 is clamped and fixed. At this time, the inclined surface and its features can be processed.

[0035] Using the above solution: by removing the workpiece pad 13, and using the bolt-fixed 60-degree positioning part 24 of the five valve body to achieve precise angle positioning, and with the five valve body inclined pad A21 and five valve body inclined pad B22 to provide lateral limiting support for the five valve body inclined workpiece 20, and combined with the coordinated clamping of the five valve body push clamping block 23 and the bidirectional top block, the stable clamping of the five valve body in a 60-degree inclined position can be achieved. It effectively solves the technical shortcomings of traditional fixtures that cannot be adapted to clamping the inclined surface of the valve body and cannot process the inclined surface features. Without changing the fixture, the precision machining of irregular surfaces such as inclined surfaces, inclined holes, and inclined grooves of the valve body can be completed by simply changing the positioning parts, which greatly improves the multi-faceted and multi-angle multi-functional machining adaptability of the fixture.

[0036] The internal clamps of the long push rod top block 8 and the short push rod top block 10 hold multiple five-valve body shoulder supports 25 and five-valve body shoulder positioning parts 26; After the workpiece pad 13 is removed, the five-valve body shoulder positioning part 26 is fixed to the first crossbeam 2 and the second crossbeam 3 with bolts. When the first oil cylinder 4 and the second oil cylinder 5 push the long push rod top block 8 and the short push rod top block 10 to move respectively, the five-valve body is clamped and fixed. At this time, the shoulder and its features can be processed.

[0037] Using the above solution: by removing the conventional workpiece pad 13 and mounting the fixed five-valve body shoulder positioning component 26, the irregular structural features of the five-valve body shoulder 25 can be precisely matched, and the position of the valve body shoulder can be exclusively limited and positioned. With the cooperation of the first hydraulic cylinder 4 and the second hydraulic cylinder 5, the bidirectional top block is driven to achieve a close-fitting clamping, which can accurately fix the processing posture of the valve body shoulder. This effectively solves the problems of traditional fixtures being unable to position and clamp the valve body shoulder, and making it difficult to complete the processing of shoulder features. It can stably complete the precision processing of exclusive features such as the end face of the valve body shoulder, shoulder hole, and shoulder step, further enriching the multi-functional clamping conditions of the fixture and realizing full coverage processing of different structures and different processing surfaces of the valve body.

[0038] Working principle and usage process of this invention: First, based on the actual clamping situation of the five valve bodies, select the appropriate fixtures, namely the five valve body positioning fixture A and the five valve body positioning fixture B, as well as the five valve body push clamping block; select the appropriate pads, namely the 32mm thick workpiece pad, the 44mm thick workpiece pad, and the 64mm thick workpiece pad. Secondly, depending on the placement, it can be formed Figure 5 The workpiece removal pad 13 shown can simultaneously process twenty five-valve body side features; Figure 6 The example shown uses a 44mm thick workpiece pad, which can simultaneously process the bottom features of six five-valve bodies. Figure 7 The example shown uses a 64mm thick workpiece pad, which can simultaneously process the bottom features of four five-valve bodies. Figure 8 and Figure 9 As shown, the machinable bevels and shoulders and their features; Hydraulic oil is injected into the first cylinder 4 and the second cylinder 5 through the stainless steel pipe 12, so that the valve body is clamped by the long push rod 6, the top flange 7, the long push rod top block 8, the short push rod 9 and the short push rod top block 10 respectively. The workpiece pad 13 can be replaced to accommodate the other surfaces of the valve body to be processed. When the short push rod top block 10 is about to clamp, the negative pressure machine 31 is started, so that it can draw the conical groove 27 and filter plate 28 into the clamping area through the second pipe 30 and the first pipe 29, and remove the impurities left in the clamping area after each operation.
