Description

Technical Field

[0001] This utility model relates to the field of valve component processing technology, specifically to a double-sided milling fixture for valve component processing. Background Technology

[0002] Valves, as key devices for controlling fluid flow rate, pressure, and direction, play an indispensable role in industrial production, daily life, and various mechanical equipment. With the continuous advancement of industrial technology and the increasing demands of modern production, higher requirements are being placed on the machining precision and efficiency of valve components. Milling is a common precision machining method in the valve component manufacturing process, and double-sided milling technology is particularly important when high-precision machining of features such as planes, ends, and grooves of valve components is required.

[0003] The patented double-sided milling fixture for valves and pipe fittings, disclosed in announcement number CN215200840U, employs a bidirectional clamping mechanism in conjunction with a fixed V-block and stepped positioning column. This fixture can simultaneously position and clamp two different sides of a product for double-sided processing, thereby improving processing efficiency.

[0004] Although the aforementioned double-sided milling fixture for valve fittings enables machining on both sides, thus improving processing efficiency to some extent, it still has certain shortcomings and areas for improvement in actual operation. Specifically, the fixture cannot automatically switch the positions of the two valve fittings, making milling operations inconvenient.

[0005] Therefore, it is necessary to invent a double-sided milling fixture for machining valve components to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a double-sided milling fixture for processing valve components, so as to solve the problems in the above-mentioned technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a double-sided milling fixture for processing valve components, comprising a base, a support plate fixedly connected to each of the top two ends of the base, a bearing plate rotatably connected between the two support plates, two clamping assemblies provided on the front of the bearing plate, an operation indicator area provided on the surface of the base, one of the clamping assemblies being located above the operation indicator area, and the clamping assembly comprising a loading base plate, an electric push rod, a movable clamping plate and a fixed clamping plate;

[0008] A ball screw is rotatably connected to the back of the support plate, and a No. 1 motor is installed on the back of the support plate. One end of the ball screw is driven to the output shaft of the No. 1 motor. Two moving blocks are connected to the surface of the ball screw through a threaded drive. A No. 1 limiting slide groove is opened in the middle of the support plate. Both moving blocks are slidably connected to the No. 1 limiting slide groove. Both moving blocks pass through the No. 1 limiting slide groove and are fixedly connected to the back of the two loading base plates respectively.

[0009] By setting two clamping components on the carrier plate, and switching between the clamping components to achieve alternating processing, the processing efficiency is improved.

[0010] Preferably, a second motor is installed on one side of one of the support plates, and one end of the bearing plate is connected to the output shaft of the second motor.

[0011] By using a second motor to drive the support plate to rotate 180 degrees, the valve fittings can be automatically swapped at both ends without manual operation, thus improving processing efficiency.

[0012] Preferably, the electric push rod is installed at one end of the front of the loading base plate, the movable clamp is located at the middle position of the front of the loading base plate, and the fixed clamp is fixedly connected to the other end of the front of the loading base plate, and the fixed clamp matches the movable clamp.

[0013] By using an electric push rod to push and pull the movable clamping plate, the clamping assembly can quickly clamp and release the valve fittings.

[0014] Preferably, one end of the electric push rod is fixedly connected to the non-clamping surface of the movable clamping plate, and both the clamping surface of the movable clamping plate and the clamping surface of the fixed clamping plate are fixedly connected with rubber anti-slip pads.

[0015] The design of the rubber anti-slip pads ensures stable clamping of valves and fittings during processing, preventing displacement and slippage.

[0016] Preferably, the loading substrate has a second limiting groove on its front side, and a limiting slider is fixedly connected to one end of the movable clamping plate. The limiting slider is slidably connected to the second limiting groove.

[0017] The sliding connection between the limit slider and the second limit groove ensures the stability and accuracy of the movable clamp during movement.

[0018] Preferably, the number of the second limiting groove and the limiting slider are both set to two, the two second limiting grooves are symmetrically distributed about the center line of the loading substrate, and the two limiting sliders are symmetrically distributed about the center line of the movable clamping plate.

[0019] The two second-level limit grooves and the two limit sliders are symmetrically distributed about their respective center lines, which enhances the stability of the movable clamp during movement.

[0020] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0021] 1. By driving the ball screw with motor No. 1, the two clamping components can be quickly switched, so that while one valve fitting is being milled, the other valve fitting can be quickly prepared, without the need for manual switching, reducing waiting time and thus significantly improving processing efficiency;

[0022] 2. The bearing plate is rotated 180 degrees by the No. 2 motor, so that the two ends of the valve assembly can be interchanged, which makes it convenient to mill the two ends of the valve fitting without the need for manual reversal, further saving time and manpower.

[0031] This utility model provides, for example Figure 1-5A double-sided milling fixture for processing valve components is shown, including a base 1, a support plate 2 fixedly connected to each of the top two ends of the base 1, a bearing plate 3 rotatably connected between the two support plates 2, two clamping components 4 provided on the front of the bearing plate 3, and an operation indication area 5 provided on the surface of the base 1, one of the clamping components 4 being located above the operation indication area 5. The clamping component 4 includes a loading base plate 6, an electric push rod 7, a movable clamping plate 8, and a fixed clamping plate 9.

[0032] A ball screw 10 is rotatably connected to the back of the support plate 3. A motor 11 is installed on the back of the support plate 3. One end of the ball screw 10 is connected to the output shaft of the motor 11. Two moving blocks 12 are connected to the surface of the ball screw 10 through threaded transmission. A first limiting slide groove 13 is opened in the middle of the support plate 3. Both moving blocks 12 are slidably connected to the first limiting slide groove 13. Both moving blocks 12 pass through the first limiting slide groove 13 and are fixedly connected to the back of the two loading base plates 6 respectively.

[0033] In one aspect of this embodiment, a second motor 14 is installed on one side of one of the support plates 2. One end of the bearing plate 3 is connected to the output shaft of the second motor 14. An electric push rod 7 is installed on one end of the front of the loading base plate 6. A movable clamping plate 8 is located at the middle position of the front of the loading base plate 6. A fixed clamping plate 9 is fixedly connected to the other end of the front of the loading base plate 6. The fixed clamping plate 9 matches the movable clamping plate 8. One end of the electric push rod 7 is fixedly connected to the non-clamping surface of the movable clamping plate 8. Rubber anti-slip pads 15 are fixedly connected to both the clamping surface of the movable clamping plate 8 and the clamping surface of the fixed clamping plate 9. A second limiting groove 16 is opened on the front of the loading base plate 6. A limiting slider 17 is fixedly connected to one end of the movable clamping plate 8. The limiting slider 17 is slidably connected to the second limiting groove 16. The number of the second limiting groove 16 and the limiting slider 17 are both set to two. The two second limiting grooves 16 are symmetrically distributed about the center line of the loading base plate 6, and the two limiting sliders 17 are symmetrically distributed about the center line of the movable clamping plate 8.

[0034] The electric actuator 7 mentioned above is an existing technology product, and its specific structure and function will not be described in detail here.

[0035] Working principle of this utility model:

[0036] Refer to the instruction manual appendix Figure 1-5 When using this utility model, firstly, place the two valve fittings between the movable clamping plate 8 and the fixed clamping plate 9 of the two clamping assemblies 4 respectively, and push the movable clamping plate 8 towards the fixed clamping plate 9 by the electric push rod 7 until the valve fittings are clamped.

[0037] Since one of the clamping components 4 is located above the operation instruction area 5, the valve fittings on it can be directly milled by the milling device. After the milling of one end of the valve fitting is completed, the clamping components need to be switched to mill the other valve fitting.

[0038] The first motor 11 drives the ball screw 10 to rotate. The rotation of the ball screw 10 drives the two moving blocks 12 to slide along the first limiting slide groove 13. The sliding of the moving blocks 12 drives the clamping assembly 4 to move, realizing the rapid switching of the clamping assembly 4. The original clamping assembly 4 is moved away, and the other clamping assembly 4 is moved above the operation indicator area 5, which facilitates the milling of one end of another valve fitting.

[0039] After the same end of both valve fittings is milled, the bearing plate 3 is rotated 180 degrees by the second motor 14 so that the two ends of the valve fittings are swapped. Then the other end of the valve fittings is milled. With the cooperation of the first motor 11 and the ball screw 10, the positions of the two clamping components 4 are switched back again so that the other ends of both valve fittings can be milled.

[0040] After milling is completed, the movable clamping plate 8 is pulled back to its initial position by the electric push rod 7, and the valve fittings are released for easy and quick removal.
