Abstract
The invention relates to a novel locating and clamping device used when a middle sleeve on a forklift is grinded. The novel locating and clamping device is mainly composed of a centering shaft, a left location plate, two adjusting rods, a right location plate, an elastic sleeve, locking nuts and three jackscrew bolts. The left location plate is fixed on the centering shaft through a fixing pin, the other end of the centering shaft is provided with the right location plate, the elastic sleeve is arranged between the centering shaft and the right location plate, the elastic sleeve is locked by the locking nuts through a right lateral pressing plate, a supporting plate is installed on the right side of a shaft shoulder of the centering shaft, an adjusting rod penetrates through the left location plate, the right location plate and the supporting plate, the two ends of the adjusting rod are locked through nuts, and the jackscrew bolts penetrate through the right location plate to be connected with the supporting plate. By means of the technical scheme, the novel locating and clamping device is low in manufacturing cost, small in workpiece deformation, high in machining accuracy and convenient to disassemble.
Description
Technical field
The present invention relates to fork truck manufacturing equipment field, be specifically related to a kind of for novel positioning clamping device during intermediate sleeve grinding on fork truck.
Background technology
In dragging formula fork truck, there is a kind of typical large diameter thin wall part---intermediate sleeve, its diameter of bore is 102mm, external diameter is 107mm, wall thickness is only 5mm, and the accuracy of form and position between each size of this part has relatively high expectations, and roundness of external circle error requirements is less than 0.0050mm.Because part wall thickness is thinner, bowlder outside grinding, if do not taken measures, usually can make workpiece produce larger distortion because of reasons such as clamping force, grinding force, grinding heat, internal stress, can not guarantee the crudy of part.
Summary of the invention
The object of the invention is to overcome the problem that prior art exists, provide a kind of for novel positioning clamping device during intermediate sleeve grinding on fork truck.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of for novel positioning clamping device during intermediate sleeve grinding on fork truck, mainly by centration axis, left location-plate, two adjusting rods, right location-plate, resilient sleeve, locking nut and three jackscrew bolts form, described left location-plate is fixed in described centration axis by steady pin, at the described centration axis other end, described right location-plate is installed, between described centration axis and described right location-plate, be provided with described resilient sleeve, described resilient sleeve is locked by described locking nut by right side pressing plate, shaft shoulder right side in described centration axis is provided with gripper shoe, described adjusting rod is through described left location-plate, right location-plate and gripper shoe, and described adjusting rod two ends are by nut check, described jackscrew bolt is connected with described gripper shoe through described right location-plate.
Further, described resilient sleeve is taper, and internal taper is 20 degree, and described adjusting rod and described jackscrew bolt are respectively 180 degree and 120 degree are distributed on described right location-plate, staggers mutually in the position of described adjusting rod and described jackscrew bolt.
The invention has the beneficial effects as follows:
Adopt technical solution of the present invention, low cost of manufacture, can prevent workpiece deformation, and machining accuracy is high, and convenient disassembly, and product percent of pass is high.
