Abstract
The utility model discloses a positioning clamping device for a moving arm cover board. Clamping blocks are moved to the outer periphery of the cover board by a hydraulic cylinder, the width of a lower cover board and a side board is limited by the clamping blocks, and accordingly the width of space between an upper cover board and the lower cover board is positioned. By the positioning clamping device for the moving arm cover board, deformation of the cover board in formation can be eliminated. After a moving arm is assembled and welded, the hydraulic cylinder retracts to disconnect the positioning blocks from the moving arm. The clamping device can be lifted out after a gap is reserved.
Description
Technical field
The utility model relates to a kind of excavator swing arm cover plate positioning clamping device.This device is easy to operate, flexibly, can effectively clamp the upper and lower cover plate of swing arm.
Background technology
At present, we are to rely on common C clamp tool in the upper and lower cover plate of dress weldering swing arm, beat the C clamp tool with manpower, make it clamp the upper and lower cover plate of swing arm, thereby eliminate the gap, let the width dimensions between upper and lower cover plate satisfy dress weldering requirement.But after using a period of time, can be owing to common C clamp wearing and tearing, perhaps placement location is improper, thereby is difficult to guarantee the width dimensions of upper and lower cover plate, in use can cause common C clamp to fly out simultaneously, has very big potential safety hazard.
Summary of the invention
The purpose of the utility model is to provide installs fixture block in a kind of C clamp; Fixture block connects hydraulic jack and conducting electric hydraulic pump, according to the work characteristics of hydraulic jack, through the position motion of oil cylinder; After cover plate reaches required size about making; Clip solid sad cover plate up and down by hydraulic oil, solve the upper and lower cover plate of swing arm can't be located clamping fast in weld clamp problem, practical and convenient quick.
The technical scheme that the utility model adopted is: a kind of swing arm cover plate positioning clamping device; This device comprises fixture block, C clamp, connector, nut, bearing pin, the axis of guide and hydraulic jack; First fixture block (2), second fixture block (4) are installed in the C clamp (3), and second fixture block (4) is connected with hydraulic jack (11), and hydraulic jack (11) has oil pipe (13) to connect electric hydraulic pump (12); First fixture block is fixed by bolts on the C clamp (3); Second fixture block (4) is installed on the axis of guide with connector (6), nut (5), and hydraulic jack (11) is passed the upper cover plate peripheral position through the axis of guide (10) with second fixture block (4), and first fixture block (2) is arranged between lower cover and the side plate.First fixture block (2) is connected with C clamp (3) through bolt (1).Second fixture block (4) has connector (6), hanger (7), bolt and nut (9) to be connected with hydraulic jack (11).
The utility model has the advantages that: swing arm cover plate positioning clamping device, in the upper and lower cover plate of dress weldering swing arm, can utilize this swing arm cover plate positioning clamping device clamping work pieces, it is convenient to make, effectively clamps, and can guarantee the width dimensions between upper and lower cover plate.Easily fast swing arm cover plate positioning clamping device, and efficient height, dependable performance, simple in structure, easily manufactured, with low cost.

The specific embodiment
The most preferred embodiment of the utility model is such: with reference to accompanying drawing,
1, is used in this swing arm cover plate positioning clamping device on the swing arm dress weldering mould, confirms the width dimensions between upper and lower cover plate, make the profile of swing arm correct in assembling;
2, second fixture block (4) is under the traction of hydraulic jack (11): (one) hydraulic jack (11) elongation; Guide effect through the axis of guide (10); Confirm the width dimensions between first fixture block (2) and second fixture block (4); Make the width between the upper and lower cover plate of swing arm correct in assembling, so the length dimension of the axis of guide (10) is not less than the stroke of hydraulic jack (11); (2) hydraulic jack (11) shrinks, and through the guide effect of the axis of guide (10), second fixture block (4) is retracted to swing arm fully disengages, and makes swing arm after assembling is accomplished, move back mould easily;
3, adjust the relative position of first fixture block (2), second fixture block (4) and swing arm cover plate, guarantee swing arm cover plate positioning clamping device in use not can with the relative motion of swing arm main body, avoid having influence on the correctness of fitted position;
4, first fixture block (2) cooperates in assembling with second fixture block (4): first fixture block (2) clamps swing arm cover plate up and down, and the upper and lower cover plate of swing arm width dimensions in assembling is guaranteed;
5, after assembling is accomplished; Hydraulic jack is shunk, and under the traction of hydraulic jack (11), second fixture block (4) unclamps then; First fixture block (2) and second fixture block (4) are all disengaged with the swing arm that assembles, just can swing arm cover plate positioning clamping device be hung.
6. hydraulic jack (11) moves to upper cover plate Outside Dimensions place through the axis of guide (10) with second fixture block (4), and the width position of lower cover and side plate is limited by first fixture block (2), and the width dimensions between upper and lower like this cover plate is able to the location.This assembling-welding fixtures after the weldering of swing arm dress is accomplished, makes the hydraulic jack counteragent owing to adopted hydraulic-driven, can second fixture block (4) not unclamped by manpower, thereby realize separating of clamping device and swing arm.
