Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool accessories, in particular to a clamping device for valve processing. Background Art

[0002] Valves are one of the most common control devices in the process of fluid material transportation. They are mainly composed of three parts: valve body, valve stem and valve core. One of the most common equipment in the valve production process is the lathe. The lathe can be used to grind, bore and tap the valve to meet the use requirements. The valve needs to be clamped when it is processed by the lathe. The clamping device is used to clamp the valve blank to make it stable on the lathe, ensuring that the lathe can carry out the processing process on it stably.

[0003] A Chinese patent application (or patent) with the announcement number CN221538902U discloses a positioning tool for valve processing, including a mounting head, a bottom plate is arranged below the mounting head, a first support plate is welded to the bottom of the mounting head, the bottom of the first support plate is connected to a sleeve by hinge rotation, a slide rail is installed below the outer wall of the first support plate, a slider is slidably clamped on the outer wall of the slide rail, a first threaded rod is installed at the bottom of the slider, and the outer wall of the first threaded rod is threadedly connected to a second support plate fixedly connected to the outer wall of the sleeve. The utility model relates to the field of valve technology. The positioning tool for valve processing can adjust the angle of the valve more conveniently after the valve is installed through the cooperation of the mounting head, the bottom plate, the slide rail, the slider, the first threaded rod, the rotating plate, the second threaded rod and the tightening block, and can better process different angles of the valve, which can greatly improve the scope of application of the positioning tool for valve processing and bring convenience to the staff.

[0004] The above-mentioned positioning fixture for valve processing has bolts on its base, and the base is fixedly installed on the surface of a lathe or other workbench by bolts. During the processing, large vibrations will be generated, and this part of the vibration will be transmitted to the workbench or lathe through the base, which will not only generate noise, but also cause certain processing deviations. In addition, a first threaded rod is abutted on one side of the bottom of the first support plate, and a mounting head for installing the valve is welded on the top of the first support plate. The first support plate is rotated by turning the screw rod, and the valve installed on the mounting head is tilted. However, the tilting is not assisted by a limiting structure. Therefore, when the mounting head and the valve thereon are tilted and then the valve is processed, it is easy to cause the valve to flip with the mounting head, resulting in serious failure of the processing work and damage to the processing equipment or valve. To this end, we provide a clamping device for valve processing to solve the above-mentioned problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example 1

[0031] See also Figure 1-5 The utility model is a clamping device for valve processing, comprising a base 1 and a shock absorbing assembly 3 at the bottom of the base 1. The micro damper 302 in the shock absorbing assembly 3 can reduce the vibration generated by the lathe during the valve processing.

[0032] Specifically, a rotary connector 2 is installed on the upper side wall of the base 1, and a shock absorbing assembly 3 is also installed on the bottom of the base 1. The connecting plate 303 in the shock absorbing assembly 3 is connected to the bottom side wall of the base 1 through bolts, and the bottom side wall of the connecting plate 303 is connected to the base 301 through a micro damper 302.

[0033] Furthermore, a buffer pad 301a is bonded to the bottom side wall of the base 301, and the base 301 is connected to the workbench of a lathe for processing the valve through the buffer pad 301a. A fixing frame 101 is fixedly installed on the upper side wall of the base 1, and the base 1 is connected to the rotary connector 2 through the fixing frame 101.

[0034] The operation process of this embodiment is as follows: during use, when the lathe is processing the valve, the vibration generated by the valve will be transmitted to the micro damper 302 through the base 1, and then transmitted to the surface of the processing table through the base 301 and the buffer pad 301a after being damped by the micro damper 302, wherein the micro damper 302 reduces the vibration generated by the lathe during the valve processing.

[0037] Specifically, the base plate 401 in the adjustment component 4 is detachably fixedly mounted on the shaft end of the rotary connector 2, and one end of the base plate 401 is connected to one end of the rotating plate 402 through a rotating shaft 401a, a slide rail 403 is inlaid on the rear side wall of the rotating plate 402, and a rotating rod 404b is slidably installed in the slide rail 403, and the rotating rod 404b is connected to the shaft end of the hydraulic rod 404 through a rotating sleeve 404a sleeved thereon, and a rotating sleeve 404c is also installed at the tail end of the hydraulic rod 404, and a rotating rod 404d is also inserted on the rotating sleeve 404c, and the rotating rod 404d is also rotatably connected to one end of the base plate 401.

[0039] The operation process of this embodiment is as follows: when in use, the hydraulic rod 404 extends or retracts, which pushes the rotating sleeve 404a and the rotating rod 404b on the shaft end to slide in the slide rail 403. When it slides, because it is also pulled by the hydraulic rod 404, it pushes the rotating plate 402 on the slide rail 403 to rotate around the rotating shaft 401a, thereby achieving the effect of adjusting the angle between the bottom plate 401 and the rotating plate 402.
