Description

Technical Field

[0001] This utility model relates to the field of valve processing equipment technology, and more specifically, to a valve fixture for an adjustable machining center. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control the flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium.

[0003] In the field of valve machining, traditional fixtures often suffer from poor versatility. A single fixture typically only fits a specific model or specification of valve. When machining different types of valves, the entire fixture must be replaced, increasing equipment costs and time spent changing fixtures, severely impacting machining efficiency. Furthermore, many fixtures are single-station clamping units, capable of holding only one valve at a time, resulting in low efficiency. Therefore, this paper researches and improves upon existing structures to provide an adjustable valve fixture for machining centers, aiming to achieve greater practical value. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an adjustable valve fixture for machining centers. It can effectively solve the problems of poor versatility, time-consuming replacement, and single clamping station of traditional valve fixtures. By setting up replaceable tooling and multiple clamping components, it can realize the rapid clamping and fixing of valves of different models and specifications. At the same time, the multi-station design improves processing efficiency and reduces equipment costs and changeover time.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] An adjustable valve fixture for a machining center includes a machining center connecting plate. A fixed template is installed on the top of the machining center connecting plate. Multiple replaceable tooling is installed at the middle position of the top of the fixed template. A clamping bracket is fixedly connected to both ends of the top of the fixed template by bolts. Multiple lead screws are fixedly connected to the clamping bracket by fastening nuts. A clamping pad is rotatably connected to the bottom end of the lead screw.

[0009] Furthermore, the top of the machining center connecting plate is fixedly connected with two positioning pins B, and the bottom of the fixed template is provided with positioning holes B corresponding to the positions of the positioning pins B. The machining center connecting plate and the fixed template are engaged with each other through the positioning holes B and the positioning pins B.

[0010] Furthermore, a positioning pin A is fixedly connected to the top of the fixed template corresponding to the position of the replaceable tooling, and a positioning hole A is opened at the bottom of the replaceable tooling. The fixed template and the replaceable tooling are engaged by the positioning pin A and the positioning hole A.

[0011] Furthermore, the clamping bracket includes a column fixed to the top of one end of the fixed template and a mounting base fixed to the bottom of the other end of the fixed template. A crossbeam is rotatably connected to the top of the column, and a hook is fixedly connected to the bottom of the end of the crossbeam away from the column. A positioning rod is rotatably connected to the top of the mounting base via a pin, and the top end of the positioning rod is engaged with the hook.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) This solution, by setting up a replaceable tooling and a matching structure with positioning pin A and positioning hole A, can quickly replace the tooling according to the shape and size of different valves without replacing the entire fixture body, greatly improving the adaptability to various valve models and effectively solving the problem of poor versatility of traditional fixtures. At the same time, the machining center connecting plate and the fixed template achieve precise positioning and quick assembly and disassembly through positioning pin B and positioning hole B. The crossbeam of the clamping bracket and the positioning rod adopt a hook snap-fit ​​design. Combined with the adjustment method of screw and fastening nut, the operation steps are simplified when changing valve models or performing maintenance, which greatly shortens the changeover time and reduces the increase in equipment costs and production efficiency losses caused by frequent fixture replacement.

[0017] (2) This solution, by setting multiple replaceable tooling on the top of the fixed template and cooperating with multiple screws and clamping pads to form a clamping assembly, forms a multi-station clamping structure, which can clamp and fix multiple valves at the same time, significantly improving the batch processing efficiency in the processing process and reducing the waiting time for single workpiece processing.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] Example:

[0034] Please see Figures 1-5 An adjustable valve fixture for a machining center includes a machining center connecting plate 1, a fixed template 2 installed on the top of the machining center connecting plate 1, multiple replaceable tooling 3 installed at the middle position of the top of the fixed template 2, and clamping brackets 4 fixedly connected to the two ends of the top of the fixed template 2 by bolts. Multiple lead screws 5 are fixedly connected to the clamping brackets 4 by fastening nuts, and clamping pads 6 are rotatably connected to the bottom end of the lead screws 5.

[0035] See Figure 5 The top of the machining center connecting plate 1 is fixedly connected with two positioning pins B7. The bottom of the fixed template 2 is provided with positioning holes B corresponding to the positioning pins B7. The machining center connecting plate 1 and the fixed template 2 are engaged by the positioning holes B and the positioning pins B7.

[0036] See Figure 5 The top of the fixed template 2 is fixedly connected to the position of the replaceable tooling 3 with a positioning pin A8. The bottom of the replaceable tooling 3 is provided with a positioning hole A. The fixed template 2 and the replaceable tooling 3 are engaged by the positioning pin A8 and the positioning hole A.

[0037] See Figure 2 The clamping bracket 4 includes a column 401 fixed to the top of one end of the fixed template 2 and a mounting base 402 fixed to the bottom of the other end of the fixed template 2. A crossbeam 403 is rotatably connected to the top of the column 401. A hook 404 is fixedly connected to the bottom of the end of the crossbeam 403 away from the column 401. A positioning rod 405 is rotatably connected to the top of the mounting base 402 through a pin. The top of the positioning rod 405 is engaged with the hook 404.

[0038] See Figure 2 The crossbeam 403 has multiple through holes, through which the lead screw 5 passes and is fixedly connected to the crossbeam 403 by fastening nuts.

[0039] See Figure 2 The top of the positioning rod 405 has a locking hole, and the hook 404 is engaged with the positioning rod 405 through the locking hole.

[0040] In use: First, fix the machining center connecting plate 1 to the worktable of the machining center with bolts to ensure a stable installation. Next, select the appropriate replaceable tooling 3 according to the model and specifications of the valve to be processed, align the positioning hole A at the bottom of the tooling with the positioning pin A8 at the top of the fixed template 2, and snap it into place downwards to achieve precise positioning of the replaceable tooling 3 and the fixed template 2. Then, align the positioning hole B at the bottom of the fixed template 2 with the positioning pin B7 at the top of the machining center connecting plate 1, so that the fixed template 2 is placed stably on the machining center connecting plate 1, completing the initial positioning. After that, place the valve to be processed on the replaceable tooling 3 and adjust the valve position to the correct posture required for processing. Then, rotate the crossbeam 403 of the clamping bracket 4 to cover the valve, and rotate the positioning rod 405 around the pin on the mounting base 402 so that the locking hole at the top of the positioning rod 405 engages with the hook 404 at the bottom of the crossbeam 403, thereby fixing the position of the crossbeam 403. Next, adjust the position of the lead screw 5 in the through hole of the crossbeam 403 according to the height and shape of the valve. Rotate the fastening nut to move the lead screw 5 downwards, causing the clamping pad 6 to fit tightly against the valve surface. Continue tightening the fastening nut until the valve is securely clamped, preventing displacement during processing. After completing the above steps, the machining center can be started to process the valve. When it is necessary to change to a different model of valve, simply loosen the fastening nut, move the lead screw 5 upwards to disengage the clamping pad 6 from the valve surface, then rotate the positioning rod 405 to separate the hook 404 from the locking hole. Flip the crossbeam 403, remove the processed valve, and then follow the above clamping steps to replace the replaceable fixture 3 and clamp the new valve. The entire replacement process is quick and convenient, effectively improving processing efficiency.
