Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, and in particular to a tooling fixture for multi-faceted processing of a three-way valve. Background Technology

[0002] Currently, metal processing is the process of making various metal parts from metal materials through physical processing methods such as forging, rolling, and cutting. Its processing technology includes stamping, turning, milling, welding, and surface treatment.

[0003] CNC milling is a process that uses a CNC milling machine to cut workpieces with a rotating multi-bladed tool. It achieves automated machining through G-code programming and is suitable for machining complex shapes such as planes, grooves, and curved surfaces.

[0004] However, in actual production, due to the different positions of the workpieces to be processed, the workpieces need to go through multiple processing steps to form. Conventional processes require multiple milling operations, resulting in low processing efficiency, so improvements are needed. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a three-way valve multi-face machining tooling fixture, which can improve the efficiency of workpiece milling.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A multi-faceted machining fixture for a three-way valve includes a base with a placement groove for mounting a workpiece to be processed. The placement groove communicates with the side of the base. Both the upper and lower sides of the base have clearance slots for milling operations, and both clearance slots communicate with the placement groove. An elastic clamping assembly is also provided on the base. The elastic clamping assembly includes a clamping block, a spring, and a locking element. The clamping block is vertically and slidably disposed on one side of the clearance slot. The spring is located between the clamping block and the base. The locking element is threadedly connected to the base and rotatably connected to the clamping block. When the clamping block clamps the workpiece to be processed into the placement groove, the spring is compressed, and the upper end of the locking element abuts against the upper side of the clamping block.

[0008] By adopting the above technical solution, the base is fixed to a CNC milling machine to achieve milling. The raw material of the workpiece to be processed is a bar. A placement groove is provided and communicates with the side, so that the bar can be inserted into the placement groove from the side. The workpiece is clamped and fixed by an elastic clamping component. The clearance slots on the upper and lower sides facilitate the milling of the upper and lower sides of the workpiece. The operation is to flip the workpiece after milling one side and then mill the other side. When the base is erected, the end of the workpiece exposed on the side of the base can be milled. In this way, with the tooling fixture of the technical solution of this application, multi-sided milling of the workpiece can be achieved by simply adjusting the base, which greatly improves the milling efficiency of the workpiece.

[0009] In one possible implementation, a positioning post is provided in the placement groove. When the workpiece to be processed is clamped and fixed in the placement groove, the positioning post is adapted to be positioned at one end of the workpiece to be processed. The axis of the positioning post is perpendicular to the axis of the machining tool of the CNC milling machine.

[0010] By adopting the above technical solution, the positioning column has two main functions: first, to facilitate the positioning operation of the workpiece; and second, to provide a certain auxiliary support. Since the workpiece to be processed has clearance slots on both the upper and lower sides, the workpiece is relatively weak under force during processing on the upper and lower sides. The positioning column can improve the stability of the support force of the workpiece to be processed.

[0011] In one possible implementation, the positioning post is cylindrical, and the positioning snap-fit ​​end of the positioning post is chamfered.

[0012] By adopting the above technical solution, the cylindrical shape and chamfered design of the positioning post facilitate the positioning and docking of the positioning post with the workpiece to be processed.

[0013] In one possible implementation, the base is provided with a plurality of placement slots, and a set of elastic clamping components is provided between each pair of adjacent placement slots, the clamping blocks pressing against the upper side of the two workpieces to be processed.

[0014] By adopting the above technical solution and setting up several placement slots, the synchronous clamping and processing of multiple workpieces can be achieved, thereby improving processing efficiency. By having a set of elastic clamping components for every two workpieces to be processed, the space layout is reasonable, and the number of elastic clamping components used is reduced while meeting the workpiece clamping requirements.

[0015] In one possible implementation, the base is provided with a sliding guide groove, and the clamping block is slidably installed into the sliding guide groove.

[0016] By adopting the above technical solution, the installation of the sliding guide groove mainly involves the stable lifting and lowering operation of the clamping block.

[0017] In one possible implementation, the clamping block has a mounting groove at its lower end, and the spring is installed in the mounting groove. When the clamping block clamps the workpiece to be processed into the placement groove, there is a gap between the lower end of the clamping block and the bottom of the sliding guide groove.

[0018] By adopting the above technical solution, the installation groove is designed to facilitate the stable installation of the spring.

[0019] In one possible implementation, the clamping block is provided with a countersunk groove for embedding and installing the locking head of the locking element.

[0020] By adopting the above technical solution, the countersunk groove is designed to facilitate the concealment of the head of the locking component, reduce its protrusion from the base plane, and reduce the impact on milling operations.

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] 1. The base is fixed to a CNC milling machine to perform milling. The raw material of the workpiece to be processed is a bar. A placement groove is provided and communicates with the side to facilitate the insertion of the bar into the placement groove from the side. The workpiece is clamped and fixed by an elastic clamping component. The clearance slots on the upper and lower sides facilitate the milling of the upper and lower sides of the workpiece. The operation is to flip the workpiece after milling one side and then mill the other side. When the base is erected, the end of the workpiece exposed on the side of the base can be milled. Thus, with the tooling fixture of the technical solution of this application, multi-sided milling of the workpiece can be achieved by simply adjusting the base, which greatly improves the milling efficiency of the workpiece.

[0023] 2. The positioning posts have two main functions: first, to facilitate the positioning of the workpiece; and second, to provide some auxiliary support. Since the workpiece to be processed has clearance slots on both the upper and lower sides, the workpiece is relatively weak under stress during processing on the upper and lower sides. The positioning posts can improve the stability of the workpiece under stress. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] This application discloses a multi-faceted machining fixture for a three-way valve. (Refer to...) Figures 1-5 The system includes a base 1, which has a placement groove 2 for mounting the workpiece 10 to be processed. The placement groove 2 is connected to the side of the base 1. Both the upper and lower sides of the base 1 have clearance slots 3 for milling processing, and both clearance slots 3 are connected to the placement groove 2. An elastic clamping assembly 4 is also installed on the base 1. The elastic clamping assembly 4 includes a clamping block 41, a spring 42, and a locking member 43. The clamping block 41 is slidably positioned on one side of the clearance slot 3. The spring 42 is located between the clamping block 41 and the base 1. The locking member 43 is threadedly connected to the base 1 and rotatably connected to the clamping block 41. When the clamping block 41 clamps the workpiece 10 to be processed into the placement groove 2, the spring 42 is in a compressed state, and the upper end of the locking member 43 abuts against the upper side of the clamping block 41.

[0033] In this embodiment, the workpiece 10 to be processed is a cylindrical rod with a positioning hole 5 extending along its axis. The workpiece 10 is inserted into the placement groove 2 from the side of the base 1 along the axial direction. In this embodiment, the spring 42 is a compression spring 42, and the locking element 43 is a locking bolt. Figure 1 The diagram shows the structure of the workpiece 10 to be processed, the workpiece 10 without being placed, and the workpiece after processing.

[0034] In this embodiment, the base 1 is provided with two rows of placement slots 2, each row has 6 placement slots 2, and each pair of adjacent placement slots 2 is provided with a set of elastic clamping components 4. In this embodiment, there are 6 sets of elastic clamping components 4. The clamping blocks of each set of elastic clamping components 4 are pressed to the upper hemispherical position of the workpiece 10 to be processed in the corresponding two adjacent placement slots 2, which must avoid the milling processing position.

[0035] Furthermore, each placement slot 2 is equipped with a positioning post 6. The positioning post 6 is adapted to and positioned by the positioning hole 5 on the workpiece 10. When the workpiece 10 is clamped and fixed in the placement slot 2, the positioning post 6 is inserted and positioned at one end of the workpiece 10. The axis of the positioning post 6 overlaps with the axis of the workpiece 10 and is perpendicular to the axis of the machining tool of the CNC milling machine. The positioning post 6 is cylindrical, and the positioning and engaging end of the positioning post 6 is chamfered. When milling is performed from both the top and bottom surfaces, the positioning post 6 can provide auxiliary support, achieving positioning and auxiliary force support, thereby improving the stability and accuracy of milling.

[0036] Furthermore, the base 1 is provided with several sliding guide grooves 7, and each clamping block is installed in the sliding guide groove 7 by corresponding lifting and sliding. The sliding guide groove 7 is connected to the upper end face of the base 1, and the sliding guide groove 7 is connected to the clearance grooves 3 on both sides and the placement grooves 2, so as to facilitate the clamping effect of the clamping blocks on the workpiece 10 to be processed.

[0037] Furthermore, each clamping block 41 has an installation groove 8 at its lower end. The spring 42 is installed in the installation groove 8, and one end of the spring 42 extending out of the installation groove 8 presses against the bottom of the sliding guide groove 7. When the clamping block 41 clamps the workpiece 10 to be processed into the placement groove 2, there is a gap between the lower end of the clamping block 41 and the bottom of the sliding guide groove 7. The gap is greater than 1 mm to reduce interference.

[0038] Furthermore, the upper end of the clamping block 41 is provided with a countersunk groove 9 for the locking head of the locking component 43 to be embedded and installed, so as to facilitate the concealment of the bolt head of the locking component 43.

[0039] The implementation principle of a three-way valve multi-face machining fixture according to an embodiment of this application is as follows: each workpiece to be processed is installed in the placement slot 2, and the locking element 43 is screwed on to control the clamping block to move down and clamp the workpiece 10 to be processed. After each workpiece 10 to be processed is installed, the base 1 is installed on the worktable of the CNC milling lathe and fixed for milling the first side. After the processing is completed, it is rotated 180 degrees to process the other side. After the processing of the other side is completed, the base 1 is then erected to mill the end of the workpiece 10 on one side. After the processing is completed, it is rotated 180 degrees to mill the end of the workpiece 10 on the other side. After the processing is completed, the locking elements 43 are screwed on to loosen them. The clamping block moves upward under the elastic restoring force of the spring 42 to unlock the workpiece, and then each processed workpiece can be taken out.

[0040] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
