Abstract

The utility model discloses a clamp for a bottom hole of a boring sliding fork spline. The clamp for the bottom hole of the boring sliding fork spline comprises a base, wherein a fixed mounting rack and an automatic centring clamping mechanism are arranged on the base, the fixed mounting rack is provided with a fixed V-shaped block, the automatic centring clamping mechanism is provided with a movable V-shaped block of the same size and shape with the fixed V-shaped block, and an opening of the fixed V-shaped block is arranged opposite to an opening of the movable V-shaped block. The automatic centring clamping mechanism is adopted so as not to use manual clamping, alleviate labor intensity, reduce machining cost, and improve locating accuracy. A cylinder/hydraulic cylinder is adopted as a driving device of the automatic centring clamping mechanism which is in gear rack transmission so that the automatic centring clamping mechanism is scientific in principle, and easy to machine and manufacture. Morevoer, locating and clamping can be completed in only two steps. The clamp for the bottom hole of the boring sliding fork spline can also be applied to machining operation for holes of other similar parts.

Description

Boring slip yoke spline bottom outlet is used anchor clamps
Technical field
The utility model belongs to the Machining Technology field, is specifically related to a kind of boring slip yoke spline bottom outlet and uses anchor clamps.
Background technology
The anchor clamps of existing boring slip yoke spline bottom outlet; Adopt manually and clamp; Be made up of column, pressure head, rotating clamp, handle, V-block, complex structure, complex operation, labor strength are big, inefficiency, maintenance dismounting difficulty, production cost are high, and can not guarantee that the excircle of workpiece center is coaxial with the circle of contact center of V-block; This position error will occur, causes machining accuracy low.
The utility model content
The utility model is in order to solve weak point of the prior art, and the boring slip yoke spline bottom outlet that provides a kind of and can fully improve machining accuracy and operating efficiency, alleviate labor strength, reduce production costs is used anchor clamps.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: boring slip yoke spline bottom outlet is used anchor clamps; Comprise base, said base is provided with fixing and mounting bracket and automatic centering clamping mechanism, and fixing and mounting bracket is provided with fixedly V-block; The movable V-block that automatic centering clamping mechanism is provided with fixedly V-block is big or small, shape is identical, fixedly the opening of V-block and movable V-block is oppositely arranged.
Said automatic centering clamping mechanism comprises pneumatic/hydraulic cylinder, connecting rod, following tooth bar, gear, upper rack and movable installing rack; Following tooth bar and upper rack horizontal slip respectively are arranged on the base, and the clutch end of pneumatic/hydraulic cylinder is in transmission connection through connecting rod and following tooth bar, and upper rack is positioned at directly over the following tooth bar; Gear is between upper rack and following tooth bar; Following tooth bar is connected by meshing transmission through gear and upper rack, and movable installing rack is located on the upper rack, and movable V-block is located on the movable installing rack.
Adopt technique scheme, the utility model uses automatic centering clamping mechanism, needn't use manual clamping, has alleviated labour intensity, has reduced processing cost, has improved positioning accuracy.It is Power Drive Unit that automatic centering clamping mechanism adopts pneumatic/hydraulic cylinder, and through the rack-and-pinion transmission, the principle science, is easy to processing and manufacturing, and the location clamps and only needed for two steps accomplished.
The utility model also can be used for the operations in the hole of other like parts.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; The boring slip yoke spline bottom outlet of the utility model is used anchor clamps; Comprise base 1, base 1 is provided with fixing and mounting bracket 2 and automatic centering clamping mechanism, and fixing and mounting bracket 2 is provided with fixedly V-block 3; Automatic centering clamping mechanism is provided with and fixing V-block 3 sizes, movable V-block 4 that shape is identical, and fixedly the opening of V-block 3 and movable V-block 4 is oppositely arranged.
Automatic centering clamping mechanism comprises pneumatic/hydraulic cylinder 5, connecting rod 6, following tooth bar 7, gear 8, upper rack 9 and movable installing rack 10; Following tooth bar 7 and upper rack 9 horizontal slip respectively are arranged on the base 1; The clutch end of pneumatic/hydraulic cylinder 5 is in transmission connection through connecting rod 6 and following tooth bar 7; Directly over the tooth bar 7, gear 8 was between upper rack 9 and following tooth bar 7 under upper rack 9 was positioned at, and following tooth bar 7 is connected by meshing transmission through gear 8 and upper rack 9; Movable installing rack 10 is located on the upper rack 9, and movable V-block 4 is located on the movable installing rack 10.
When work is used; The piston rod of pneumatic/hydraulic cylinder 5 is to left movement, promotes connecting rod 6 motions, connecting rod 6 drive down tooth bar 7 along base 1 to left movement; 8 motions of following tooth bar 7 driven gears; Gear 8 drives upper racks 9 and moves right, and upper rack 9 drive activity installing racks 10 move right with movable V-block 4, and movable V-block 4 is clamped in movable V-block 4 with the location of workpiece 11 and fixedly between the V-block 3; Otherwise the piston rod of pneumatic/hydraulic cylinder 5 moves right, and then can realize unclamping of work piece 11.
