Description
Technical Field
The utility model relates to an anchor clamps, in particular to anchor clamps for processing special-shaped workpiece.
Background
The special-shaped parts are frequently used in industry and life, but the special-shaped parts are difficult to process. The exhaust gas exhaust valve of the truck is also a special-shaped valve. In the research and development process of processing of truck exhaust valve products, because the products are lost-wax casting blanks, the positioning reference fluctuation is large, the positioning reference is difficult to find, the products are divided into a plurality of processes, the positioning and clamping are repeated, the single beat in the process is long, the process quality management and control risk is large, the working time is wasted, and the overall efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing an anchor clamps for processing special-shaped workpiece solves the problem that anchor clamps were changed to repeated location and frequency.
The technical scheme is as follows: the utility model relates to a clamp for processing a special-shaped workpiece, which comprises a body; the body is provided with clamping components which are arranged oppositely at left and right, and each clamping component comprises a first fixed block with a fixed pin, a shell with a built-in telescopic rod and a hydraulic cylinder for driving the telescopic rod in the shell to extend or reset; the fixing pin and the telescopic rod are located at the same height and are oppositely arranged, the hydraulic cylinder is arranged below the body, and the hydraulic cylinder rod penetrates through the body and extends into the shell.
Through adopting above-mentioned technical scheme, its business turn over gas port of truck tail gas discharge valve is inside circular, consequently, when centre gripping discharge valve, discharge valve's one end cover is in the locating pin, drives the hydraulic cylinder, and hydraulic cylinder drive telescopic link extension is in order to imbed into discharge valve's the other end, has just so accomplished the location and the locking to discharge valve.
Furthermore, transition blocks are arranged at two ends of the body and fixedly connected with a rotating mechanism used for driving the body to rotate through pin shafts.
Furthermore, a plurality of positioning blocks are arranged on the body between the first fixing block and the first shell and used for positioning the exhaust valve.
Furthermore, a cushion block is arranged on the body between the first fixing block and the first shell, and the cushion block is in threaded connection with the body to adjust the height of the cushion block.
Furthermore, a positioning rod for positioning the center of the exhaust valve is arranged on the body between the first fixing block and the first shell.
Has the advantages that: compared with the prior art, the utility model: the exhaust valve is locked and positioned only once through the clamping assembly, so that the working time is saved; the fixture can also rotate, and the exhaust valve on the fixture can be machined at different angles.
Drawings
FIG. 1 is a schematic structural diagram of a fixture for machining a profiled exhaust valve.
Detailed Description
As shown in fig. 1, a fixture for processing a special-shaped workpiece comprises a body 1; the exhaust valve clamping device is characterized in that the clamping components 2 which are arranged oppositely at the left and the right are arranged on the body 1, at least two groups of clamping components 2 are arranged on the body 1 for processing at least two exhaust valves in a one-step mode, and one exhaust valve is clamped by one clamping component 2.
The clamping assembly 2 comprises a first fixed block 22 with a fixed pin 21, a shell 24 with a built-in telescopic rod 23 and a hydraulic cylinder 25 for driving the telescopic rod 23 in the shell 24 to extend or reset; the fixed pin 21 and the telescopic rod 23 are positioned at the same height and are oppositely arranged, the hydraulic cylinder 25 is arranged below the body 1, and the rod of the hydraulic cylinder 25 penetrates through the body 1 and extends into the shell 24.
The inside of the air inlet and the air outlet of the exhaust valve are circular, so that when the exhaust valve is clamped, one end of the exhaust valve is sleeved in the positioning pin to drive the hydraulic cylinder 25, the hydraulic cylinder 25 drives the telescopic rod 23 to extend to be embedded into the other end of the exhaust valve, and the positioning and the locking of the exhaust valve are completed.
When the exhaust valve needs to be machined by other parts, in order to avoid dismounting and mounting the exhaust valve again to obtain a new machining angle, the clamp can rotate to obtain the angle of the exhaust valve to be machined, therefore, transition blocks 3 are arranged at two ends of the body 1, and the transition blocks 3 are fixedly connected with a rotating mechanism for driving the body 1 to rotate through pin shafts.
In order to obtain a more accurate machining angle of the exhaust valve, a plurality of positioning blocks 4 are arranged on the body 1 between the first fixing block 22 and the first shell 24, the positioning blocks 4 are used for positioning the exhaust valve, and a positioning rod 6 used for positioning the center of the exhaust valve is arranged on the body 1 between the first fixing block 22 and the first shell 24
As the exhaust valve is shaped like a special body, the surface height of the exhaust valve is inconsistent, in order to better support the exhaust valve, a cushion block 5 is arranged on the body 1 between the first fixing block 22 and the first shell 24, and the cushion block 5 is in threaded connection with the body 1 to adjust the height of the cushion block 5.
