Abstract
The utility model relates to the technical field of gear shaft processing, in particular to a gear shaft positioning clamp for a pneumatic actuator, which can meet the requirements of positioning and fixing of gear shafts of different sizes and reduce cost.
Description
Technical Field
The utility model relates to the technical field of gear shaft machining, in particular to a gear shaft positioning clamp for a pneumatic actuator.
Background
The pneumatic actuator is an actuating device for driving the opening and closing or adjusting valve by air pressure, and is also called as a pneumatic actuating mechanism or a pneumatic device. The gear shaft in the pneumatic actuator is an important part, the gear shaft needs to be reliably positioned during machining, the conventional positioning clamp can only realize machining of a single size, and different positioning clamps are adopted for different model sizes, so that the machining cost is too high.
Disclosure of Invention
In order to solve the problems that the whole clamp needs to be replaced for different gear shafts in the prior art and the processing cost is high, the utility model provides the gear shaft positioning clamp for the pneumatic actuator, and a single clamp can meet the requirements of positioning and fixing gear shafts with different sizes, so that the cost is reduced.
The technical scheme is as follows: the utility model provides a gear shaft positioning fixture for pneumatic actuator, it includes the base, be provided with positioning mechanism and clamping mechanism on the base, its characterized in that, positioning mechanism includes the riser, two locating plates of symmetrical arrangement are installed through the bolt to the terminal surface before the riser, the upper end and the lower extreme of locating plate are provided with V-arrangement locating piece respectively, clamping mechanism is including setting up in two hydro-cylinder between the locating plate, the depression bar is connected to the piston rod of hydro-cylinder, the locating plate below be provided with the lower cushion that stacks the arrangement on the base, be provided with threaded rod, top intermediate the lower cushion bottom and be provided with the screw thread counter bore.
The hydraulic oil cylinder is further characterized in that the end part of a piston rod of the oil cylinder is connected with one end of a middle rod through a pin, and the other end of the middle rod is fixed with the compression rod through a screw;
the oil cylinder comprises an upper oil cylinder and a lower oil cylinder.
After the utility model is adopted, the bottom of the gear shaft to be processed is supported on the lower cushion block, the side part of the gear shaft is abutted against the V-shaped positioning block, the gear shaft is pressed by the oil cylinder to realize positioning and fixing, the proper number of lower cushion blocks can be adjusted to meet the requirements of gear shafts with different heights according to the size requirements, when the V-shaped positioning block is unsuitable, the bolts are unscrewed, the positioning plate with the proper size of the V-shaped positioning block is replaced, the oil cylinder, the base and the like do not need to be changed, the universality of the product is strong, the positioning and fixing of the gear shafts with different sizes are met, and the cost is reduced; furthermore, the compression bar can be replaced conveniently according to the requirement.
Drawings
FIG. 1 is a front view of the present utility model; (omitting the compression bar)
Fig. 2 is a top view of the present utility model.
Detailed Description
See fig. 1, fig. 2 shows, a gear shaft positioning fixture for pneumatic actuator, it includes base 1, be provided with positioning mechanism and clamping mechanism on the base 1, positioning mechanism includes riser 2, two locating plates 4 of symmetrical arrangement are installed through bolt 3 to riser 2 front end face, the upper end and the lower extreme of locating plate 4 are provided with V-arrangement locating piece 5 respectively, clamping mechanism is including setting up the hydro-cylinder 6 between two locating plates 4, can set up two, be last hydro-cylinder and lower hydro-cylinder respectively, the better realization compresses tightly the operation, the depression bar 7 is connected to the piston rod of hydro-cylinder 6, be provided with the lower cushion 8 of piling up the arrangement on the base 1 of locating plate 4 below, be provided with screw thread head 9 in the middle of the bottom of lower cushion 8, be provided with screw thread counter bore 10 in the middle of the top, lower cushion 8 can be piled up through the piece, convenient operation, lower cushion 8 can select different thickness.
The end of the piston rod of the oil cylinder 6 is connected with one end of a middle rod 12 through a pin 11, the other end of the middle rod 12 is fixed with a compression rod 7 through a screw 13, and the compression rod 7 can be replaced according to the requirement.
When the gear shaft fixing device is used, the proper number of lower gaskets are selected according to the height of the gear shaft, then the gear shaft is put into the gear shaft from top to bottom, the bottom of the gear shaft is supported on the lower gaskets and leans against the V-shaped positioning block 5, then the oil cylinder 6 is started, the piston rod is retracted, and the pressing rod 7 presses the gear shaft on the V-shaped positioning block 5 to complete fixing.
