[0001] The invention relates to the technical field of semiconductor valve block processing, and in particular to a clamping fixture for rough processing of valve block parts. Background Art

[0002] With the continuous advancement of electronic integrated circuit technology and the rapid development of intelligent manufacturing, the demand for IC equipment is showing an increasing trend. In semiconductor equipment, valve block parts play a vital role and are one of the key components to ensure the normal operation of the equipment. However, since there are many different sizes of valve block parts in IC equipment, and most of these parts are consumable parts, the demand for them is extremely high.

[0003] In the traditional valve block parts processing, precision vises are usually used for clamping. However, this method is not only time-consuming and labor-intensive, reducing processing efficiency, but also requires straightening and alignment during the clamping process, further affecting the machine rate. In addition, when using a vise to clamp parts, there is also a risk of parts floating up, which may have an adverse effect on product quality.

[0004] In view of the above problems, the industry urgently needs a more efficient and stable valve block parts rough machining clamping solution to improve machining efficiency, reduce production costs, and ensure product quality. Therefore, the present invention proposes a new type of valve block parts rough machining clamping fixture. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a clamping fixture for rough machining of valve block parts. The clamping fixture for rough machining of valve block parts makes it possible to install up to 16 valve block parts in each clamping, which greatly reduces the time required for frequent machine shutdowns to replace parts. After a single clamping, the machine can operate continuously for 8 hours, thereby significantly improving machining efficiency and machine rates.

[0006] The technical solution of the present invention is as follows: A clamping fixture for rough machining of valve block parts comprises a base plate, a limit assembly, a zero point plate and a lateral clamping fixture, wherein the zero point plate is fixedly mounted on a workbench of a machining device, and the base plate is detachably fixedly mounted on the zero point plate, and a plurality of installation stations for clamping the valve block are arranged on the base plate, and each installation station is provided with a limit assembly and a lateral clamping fixture.

[0008] The limit assembly comprises a limit block A and a limit block B. The limit block A is arranged at a position close to the length direction of the valve block, and the limit block B is arranged at a position close to the width direction of the valve block.

[0009] The limit block A and the limit block B are fixed on the bottom plate with screws.

[0010] A toothed structure is provided at the position where the limit block A and the valve block are in contact with each other.

[0011] Optionally, the base plate is connected to the zero point plate by bolts.

[0012] Preferably, the bottom plate is fixedly connected to the zero point plate via rivets, a zero point disk is fixedly arranged on the zero point plate, and the rivets are arranged between the bottom plate and the zero point disk.

[0013] The zero point plate is mounted on the base plate by means of a bolt assembly.

[0014] The base plate is made of carbon steel.

[0015] Limit block A and limit block B are made of carbon steel.

[0016] The beneficial effects of the present invention are: 1. The present invention discloses a clamping fixture for rough machining of valve block parts.

DETAILED DESCRIPTION

[0022] like Figure 1 and Figure 2 As shown, the clamping fixture for rough machining of valve block parts includes a base plate 1, a limit block A2, a limit block B3, a zero point plate 4, a screw 5, a lateral clamping fixture 6, a rivet 9 and a zero point plate 10.

[0023] like Figure 3 As shown, the bottom plate 1 is made of carbon steel and is heat-treated to increase rigidity to ensure the stability of the fixture.

[0024] like Figure 4 and Figure 5 As shown, the limit block A2 and the limit block B3 are also made of carbon steel. The limit block A2 is designed with a toothed structure to increase the friction with the valve block 11 to prevent the parts from moving or floating during the processing.

[0025] like Figure 6 As shown, the zero point plate 4 is fixedly mounted on the workbench 12 of the processing equipment to support and position the base plate 1.

[0026] Lateral clamping fixture 6: used to laterally clamp the valve block 11 to ensure the stability of the parts during processing. The following products are specifically selected: MITEE-BITE fixture; brand: Qunqing Machinery; model: MIB-56030.

[0027] Fasteners such as screws 5, bolt assemblies, rivets 9, etc. are used to connect and fix various components, wherein the screw assembly includes a screw assembly 1 7 and a bolt assembly 2 8.

[0028] Processing equipment: including a workbench 12 for installing the zero point plate 4 and processing the valve block 11.

[0029] Pneumatic tool: used to install and remove the rivet 9 to achieve quick connection between the base plate 1 and the zero point plate 4.

[0030] The limit block A2 and the limit block B3 are respectively installed on the bottom plate 1 and fixed with screws 5. The limit block A2 should be set close to the length direction of the valve block 11, and the limit block B3 should be set close to the width direction of the valve block 11.

[0031] A lateral clamping fixture 6 is installed at each installation station of the base plate 1 for laterally clamping the valve block 11 .

[0032] Install the zero point disk 10 on the zero point plate 4 and ensure that it is firm.

[0033] The connection method between the bottom plate 1 and the zero plate 4 is selected according to the actual situation. One method is to connect by bolts, and the other method is to connect by pneumatic rivets 9. If pneumatic rivets 9 are used for connection, it is necessary to reserve a mounting hole for the rivets between the bottom plate 1 and the zero plate 10.

[0034] The bottom plate 1 with the limit block A2 , the limit block B3 and the lateral clamping fixture 6 installed is placed as a whole on the zero point plate 4 .

[0035] If bolt connection is adopted, the bolt assembly is used to fix the bottom plate 1 and the zero point plate 4 together. If pneumatic rivets 9 are used for connection, the rivets 9 are driven into the reserved mounting holes using pneumatic tools to achieve quick connection between the bottom plate 1 and the zero point plate 4.

[0036] Specific use process: (1) Clamping valve block parts: Arrange the 16 blanks of valve block parts 11 on the installation station on the base plate 1 according to the predetermined position and direction. Ensure that the right angle edge of each valve block part fits tightly with the limit block A2 and the limit block B3, and the bottom surface is in close contact with the base plate 1. Use the lateral clamping fixture 6 to clamp the valve block parts 11 diagonally downward to prevent the parts from floating or moving during the processing.

[0037] (2) Processing operation: Place the assembled fixture as a whole on the workbench 12 of the processing equipment, and ensure that the zero point plate 4 is firmly fixed to the workbench 12. Start the processing equipment and perform rough processing on the valve block part 11 according to the predetermined processing technology.

[0038] (3) Disassembly and replacement: After processing, use pneumatic tools to remove the rivets 9 (if pneumatic connection is used), or use bolt assemblies to remove the base plate 1 (if bolt connection is used). Remove the base plate 1 from the zero plate 4 and replace the next batch of valve block parts 11 to be processed. Repeat the above clamping and processing steps until all valve block parts 11 are processed.

[0039] Through the above specific implementation methods, the rough machining of valve block parts can be completed efficiently and stably, thereby improving the machining efficiency and product quality.
