During valve production, valves need to be fixed in place to facilitate drilling, grinding, or polishing operations.

[0003] In the existing technology, the existing valve production fixing device is generally fixed by a clamp. The valve can be fixed by the operation of the power structure on both sides of the clamp with the cooperation of the clamp plate.

[0004] In current technologies, valve fixing is not stable, and valve deformation is easily caused during clamping. The clamping force is difficult to control, and the clamping efficiency is low. After clamping, the clamping position needs to be compared and calibrated, and the clamping accuracy is poor. Therefore, a valve production fixing device is proposed to address the above problems.

[0010] Preferably, a warning light is installed on the top side of the base, and the two electrode rings, the warning light and the power supply are connected in series. The two electrode rings are connected by contact, which can adjust the pressure state in time by the flashing state of the warning light to avoid excessive clamping and to position the shape of the valve body.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1-3 This utility model provides a valve production fixing device, including a base 1; a limiting structure 5 is fixed in the middle of the top side of the base 1, and a clamping structure 6 and a first fixing plate 7 are respectively fixed at both ends of the top side of the base 1.

[0026] A support 2 is fixed to the top side of the base 1. The support 2 is located directly below the limiting structure 5. The clamping structure 6 includes a second fixing plate 61. A hydraulic cylinder 62 is mounted on one side of the second fixing plate 61. A limiting sleeve 63 is fixed to the output end of the hydraulic cylinder 62. A rod 65 is movably inserted into the limiting sleeve 63. A second fixing post 68 is fixed to one end of the rod 65. A limiting plate 67 is fitted on the outside of the limiting sleeve 63. A second spring 64 is fixed between the end face of the second fixing post 68 and the limiting plate 67. Electrode rings 66 are fixed on the opposite surfaces of the second fixing post 68 and the limiting plate 67. Second fixing angle plates 69 are arranged in a ring array on the second fixing post 68.

[0027] A first fixing post 9 is fixed to one side of the first fixing plate 7. First fixing angle plates 8 are arranged in a circular array on the first fixing post 9. Both the first fixing angle plates 8 and the first fixing post 9 are triangular structures. The first fixing post 9 and the second fixing post 68 are coaxial. A "V"-shaped groove is provided on the top side of the support 2. The valve body 3 is placed on the support 2. A warning light 4 is installed on the top side of the base 1. Two electrode rings 66, the warning light 4, and the power supply are connected in series. The two electrode rings 66 are connected by contact. During operation, when manufacturing the valve, it is necessary to fix the valve and then drill holes at the valve stem assembly position. To improve drilling efficiency, the valve body 3 is placed on the support 2. Since the top side of the support 2 has a "V" shape, and the main body of the valve body 3 is generally cylindrical, drilling can be performed after the valve body 3 is placed. With the position facing upward, the hydraulic cylinder 62 pressurizes the valve body 3, pushing the second fixed post 68 deeper into one end of the valve body 3. With the cooperation of the first fixed post 9, it extends into the other end of the valve body 3. The cooperation of the first fixed angle plate 8 and the second fixed angle plate 69 achieves clamping support for the valve body 3, ensuring that the central axis of the valve body 3 is synchronized with the first fixed angle plate 8 and the second fixed post 68. This ensures effective clamping of the valve body 3, preventing reciprocating clamping after clamping, improving clamping efficiency, and ensuring clamping stability. Under continuous pressurization by the hydraulic cylinder 62, the limiting sleeve 63 is pushed forward, compressing the second spring 64. When the two electrode rings 66 contact, the warning light 4 flashes, promptly stopping the pressurization operation of the hydraulic cylinder 62, ensuring stable clamping, and avoiding over-clamping. This allows for controllable clamping of the valve body 3.

[0028] Please see Figure 4The limiting structure 5 includes two limiting seats 51, which are symmetrically arranged. The bottom sides of the two limiting seats 51 form an inverted "V" shape. The two limiting seats 51 are connected by a connecting rod 52. A positioning plate 53 is fixed to the outer side of the limiting seat 51. A positioning rod 54 and a guide post 55 are vertically fixed to the top side of the base 1. The positioning plate 53 has a positioning hole and a guide hole. The top end of the positioning rod 54 passes through the positioning hole, and the top end of the guide post 55 passes through the guide hole. A first spring 56 is disposed between the positioning plate 53 and the base 1, and the first spring 56 is sleeved on the outside of the guide post 55. The seat 51 and the support 2 are arranged vertically and vertically. During operation, in order to ensure the stability of clamping the valve body 3, the valve body 3 is clamped and fixed by the joint operation of the second fixed column 68 and the first fixed column 9, and by the cooperation of the first fixed angle plate 8 and the second fixed angle plate 69. During the clamping and fixing process of the valve body 3, the horizontal position of the valve body 3 will be raised. When the valve body 3 is raised, the drilling position is corrected to the middle position along the bottom slope of the limiting seat 51, so as to ensure that the drilling position of the valve body 3 after clamping is stuck between the two limiting seats 51, which can further support the valve body 3, ensure the accuracy and stability of clamping the valve body 3, and better ensure the drilling effect.

[0029] Working principle: To improve drilling efficiency, the valve body 3 is placed on the support 2. Since the support 2 has a "V" shape on its top side, and the valve body 3 is generally cylindrical, after the valve body 3 is placed, the drilling position is set upwards. Pressure is applied by the hydraulic cylinder 62, which pushes the second fixing post 68 into one end of the valve body 3. With the cooperation of the first fixing post 9, it penetrates into the other end of the valve body 3. With the cooperation of the first fixing angle plate 8 and the second fixing angle plate 69, the valve body 3 is clamped and supported, ensuring the center of the valve body 3. The shaft is synchronized with the first fixed angle plate 8 and the second fixed column 68, which can effectively clamp the valve body 3 without reciprocating after clamping, thus improving clamping efficiency and ensuring clamping stability. Under the continuous pressure of the hydraulic cylinder 62, it can push the limit sleeve 63 forward to compress the second spring 64. When the two electrode rings 66 contact, the warning light 4 is energized and flashes, which can stop the pressure operation of the hydraulic cylinder 62 in time, ensuring clamping stability and avoiding over-clamping. It can position the shape of the valve body 3 and achieve controllable clamping.

[0030] To ensure the stability of clamping the valve body 3, the valve body 3 is clamped and fixed by the joint operation of the second fixing post 68 and the first fixing post 9, and the cooperation of the first fixing angle plate 8 and the second fixing angle plate 69. During the clamping and fixing process of the valve body 3, the horizontal position of the valve body 3 will be raised. When the valve body 3 is raised, the drilling position is corrected to the middle position along the bottom slope of the limiting seat 51, ensuring that the drilling position of the valve body 3 after clamping is stuck between the two limiting seats 51, which can further support the valve body 3, ensure the accuracy and stability of clamping the valve body 3, and better ensure the drilling effect.
