Abstract
The invention discloses a selecting/shifting block locking device, which is characterized in that the device is provided with a shift wire joint shaft 1, a snap spring 2, a return spring 6, a sliding sleeve 5, a steel ball 7 and a pressure bracket 3; wherein, the lower part of the engagement wire joint shaft 1 is provided with a symmetrical steel ball hole 8; the steel ball 7 is positioned in the steel ball hole 8; the return spring 6 is sheathed on the engagement wire joint shaft 1; the sliding sleeve 5 is sheathed outside the engagement wire joint shaft 1 and is connected with the pressure bracket 3; the snap spring 2 is also sheathed on the engagement wire joint shaft 1 and is positioned between the pressure bracket 3 and the sliding sleeve 5 as well as the return spring 6. The device is used for solving the problem of fast and automatic clamping of the selecting/shifting block during function check of drag-line automobile gearboxes and realizing fast and automatic clamping function on the selecting/shifting block.
Description
Technical field
The present invention relates to a kind of drag-line gearbox gear-changing and selecting shifting block locking device, especially a kind of when being used for drag-line automobile gearbox function check, the device of shifting block automated exchanged cutter, locking usefulness.
Background technique
The choosing of drag-line automobile gearbox, gear shift function are the mobile completion that drives choosing shelves shifting block and gear shift shifting block through drag-line mechanism.In the car load assembling, can only adopt manual mode that the locking head of backguy is installed on the gear-changing and selecting shifting block; When carrying out large-scale drag-line gearbox function verification; Adopt manual mode dismounting shifting block locking mechanism on the production line, both increased labor intensity, influence manufacturing efficiency again.
Summary of the invention
The objective of the invention is to want to provide a kind of shifting block automated exchanged cutter device, the gear-changing and selecting shifting block that is used for solving drag-line automobile gearbox function check process is the clamping problem fast and automatically, realizes the function of clamping fast and automatically to gear-changing and selecting shifting block.
For realizing that the technological scheme that above-mentioned purpose of the present invention adopts is: the present invention contains engage a gear line coupling shaft, jump ring, Returnning spring, sliding sleeve, steel ball, presses down support; Be provided with the steel ball hole of symmetry in the bottom of engage a gear line coupling shaft, steel ball is positioned at steel ball hole, and Returnning spring is enclosed within on the engage a gear line coupling shaft; Its outside is with sliding sleeve; Sliding sleeve with press down support and link together, on engage a gear line coupling shaft, also be with jump ring, jump ring is pressing down between support and sliding sleeve and the Returnning spring.
Most preferred embodiment of the present invention is for to be provided with circular groove on the top of engage a gear line coupling shaft.
The present invention also is provided with the outstanding step of annular on sliding sleeve.
Slide over mobile position on the engage a gear line coupling shaft by the restriction of the jump ring of engage a gear line coupling shaft, during free state, slide under the effect of Returnning spring and withstand jump ring, steel ball receive sliding sleeve the outstanding step extruding of annular and near the inwall of engage a gear line coupling shaft.
During use, pushing downwards presses down support, promotes the sliding sleeve compression reseting spring; The outstanding position of annular that steel ball is crossed sliding sleeve gets into the bigger activity space in top; At this moment, the present invention is inserted on the gear-changing and selecting shifting block on the test bench, unclamps sliding sleeve; Steel ball receives the extruding of the outstanding step of annular and contacts with the bulb lower surface of shifting block, thereby shifting block is locked.
When grasping locking device; On test bench, install one earlier and grasp cylinder; Circular groove through engage a gear line coupling shaft upper end clamps it, adopts a locking cylinder to promote sliding sleeve then and moves down, thereby make steel ball get into the bigger activity space above the annular outstanding step; Gear-changing and selecting shifting block contacts with the steel ball disengagement, grasps cylinders retract and can gear-changing and selecting shifting block locking device be got hold of.
The present invention is simple and reasonable for structure, can realize the function of clamping fast and automatically of gear-changing and selecting shifting block effectively, and is easy to use.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the gear-changing and selecting shifting block structural representation on the test bench.
Embodiment
Example below in conjunction with accompanying drawing and practical implementation is done further detailed explanation to the present invention.
Can find out that by Fig. 1 the present invention contains engage a gear line coupling shaft 1, jump ring 2, Returnning spring 6, sliding sleeve 5, steel ball 7, presses down support 3, on sliding sleeve 5, be provided with the outstanding step 9 of annular; Top at engage a gear line coupling shaft 1 also is provided with circular groove 10; Be provided with the steel ball hole 8 of symmetry in the bottom of engage a gear line coupling shaft 1, steel ball 7 is positioned at steel ball hole 8, and Returnning spring 6 is enclosed within on the engage a gear line coupling shaft 1; Its outside is with sliding sleeve 5; Sliding sleeve 5 with press down support 3 and link together through screw 4, on engage a gear line coupling shaft 1, also be with jump ring 2, jump ring 2 is pressing down between support 3 and sliding sleeve 5 and the Returnning spring 6.
Use when of the present invention, promote sliding sleeve 5 earlier downwards, thus compression reseting spring 6, bigger activity space above the outstanding step 9 of annular that steel ball 7 is crossed sliding sleeve 5 gets into.At this moment, unclamp after packing into the present invention on the gear-changing and selecting shifting block shown in Figure 2 11, the outstanding 9 extruding steel balls 7 of annular at the effect low sleeve 5 of Returnning spring 6 make steel ball 7 closely contact and gear-changing and selecting shifting block 11 is locked with the bulb lower surface of gear-changing and selecting shifting block 11.
Grasp when of the present invention; Extracting cylinder on the test bench clamps engage a gear line coupling shaft 1 through the circular groove 10 of engage a gear line coupling shaft 1 upper end; Under the promotion of another locking cylinder on the test bench, sliding sleeve 5 moves down, and steel ball 7 gets into the big activity space above the outstanding step 9 of sliding sleeve 5 annulars; Gear-changing and selecting shifting block 11 contacts with steel ball 7 disengagements, grasps cylinders retract and can the present invention be got hold of.
