Description
Technical field
The present invention relates to a kind of car gear shifting fork verticality measuring instrument, for detecting the verticality between car gear shifting fork axis hole and pin-and-hole.
Background technology
Gear shift fork is the vitals on automobile gearbox.Existing gear shift fork is generally steel forge piece, be made up of axle sleeve, bulb, leg and wavy surface, axle sleeve is loaded on axle by the shaft hole sleeve at its center, and at the middle part of axle sleeve, radially symmetry offers pin-and-hole, primary and secondary pin is located in pin-and-hole, and axle sleeve and axle are fixed.The assembling of verticality between axis hole and pin-and-hole to gear shift fork is most important, if verticality is not good between axis hole and pin-and-hole, the assembly difficulty of gear shift fork can be increased, affect fastness and the reliability of the connection of gear shift fork, even cause gear shift fork to be difficult to be assembled on axle.Therefore, design the verticality that a set of measurer carrys out special detection gear shift fork to be very important.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of measurer that accurately can detect car gear shifting fork verticality.
Technical scheme of the present invention is as follows: a kind of car gear shifting fork verticality measuring instrument, it is characterized in that: base plate is rectangular flat structure, base plate is fixed with locating shaft, the plate face of this locating shaft and base plate is perpendicular, and the top of locating shaft radially offers detect aperture, back-up block is provided with on the side of described locating shaft, this back-up block is fixed on base plate, setting-in lining in back-up block, latch is worn in described lining, latch coordinates with casing slip, and described latch can through the detect aperture on locating shaft.
Adopt above technical scheme, when needing to detect the verticality between gear shift fork axis hole and pin-and-hole, first gear shift fork is placed on base plate, locating shaft is passed from the axle sleeve of gear shift fork, then gear shift fork is rotated, make the detect aperture on the pin-and-hole aligning locating shaft on gear shift fork axle sleeve, then latch is promoted, latch is moved towards the direction of locating shaft, if latch can through the detect aperture on the pin-and-hole of axle sleeve side and locating shaft, pass from the pin-and-hole of axle sleeve opposite side, then the verticality between this gear shift fork axis hole and pin-and-hole meets the requirements.The present invention not only structure is simple, and parts are few, and easily, cost is low in assembling; And detecting easy and simple to handle, laborsaving, testing result is accurately, reliably, detection efficiency is high.Latch coordinates with the casing slip of setting-in in back-up block, and the smoothness of latch action is good on the one hand, clamping stagnation can not occur; On the other hand, the material that both select hardness to adapt, wearing quality is good, can ensure that latch only does the motion of rectilinear direction.
In order to simplify structure, facilitate processing and fabricating and assembling, guarantee that back-up block connects on base plate firm, described back-up block is box structure, back-up block is connected with base plate by two pins, and back-up block is fixed by two screws and base plate, two pins are positioned on a pair diagonal angle of rectangle, two screws be positioned at rectangle another on diagonal angle.
Described latch is the syllogic column structure that diameter increases successively, and the interlude of latch is located in lining, and the minimal segment of latch can through the detect aperture on locating shaft.The moulding of above structure latch is simple, is easy to processing and fabricating; Step surface between latch minimal segment and interlude is spacing by gear shift fork axle sleeve, and the step surface between interlude and largest segment is spacing by lining, only need promote latch gently when detecting operation, convenient and labor-saving.
For the ease of hand-held operation, make latch insert pin-and-hole easier, the periphery of described latch largest segment is provided with annular knurl, passes through conical surface transition between the end face of latch minimal segment and periphery.
Beneficial effect: the present invention designs ingenious, structure is simple, and implement easily, parts are few, and it is convenient to assemble, and cost is low; Detect easy and simple to handle, laborsaving, testing result accurately, reliably, detection efficiency is high.

Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1 and Figure 2, the present invention is made up of base plate 1, locating shaft 2, back-up block 3, lining 4, latch 5, pin 6 and screw 7 etc.Wherein, base plate 1 is rectangular flat structure, and base plate 1 is provided with locating shaft 2, and this locating shaft 2 is perpendicular with the plate face of base plate 1, and lower end and the base plate 1 of locating shaft 2 are fixed.Radially detect aperture is offered, the two sides of the through locating shaft 2 of detect aperture on the top of locating shaft 2.
As shown in Figure 1 and Figure 2, be provided with back-up block 3 on the side of locating shaft 2, this back-up block 3 is box structure.Back-up block 3 is connected with base plate 1 by two pins 6, and back-up block 3 is fixed by two screws 7 and base plate 1.By the rectangular distribution, two pins 6 are positioned on a pair diagonal angle of rectangle for two pins 6 and two screws 7, two screws 7 be positioned at rectangle another on diagonal angle.
As shown in Figure 1 and Figure 2, fix setting-in lining 4 in back-up block 3, the both ends of the surface of lining 4 are concordant with the corresponding surface of back-up block 3.In lining 4, wear latch 5, the syllogic column structure that latch 5 increases successively for diameter, the interlude of latch 5 is located in lining 4, and is slidably matched with lining 4.The periphery of latch 5 largest segment is provided with annular knurl, and the minimal segment of latch 5 through the detect aperture on locating shaft 2, and can pass through conical surface transition between the end face of latch 5 minimal segment and periphery.
Principle of work of the present invention is as follows:
As Fig. 3, Fig. 4 and shown in composition graphs 1, Fig. 2, gear shift fork is steel forge piece, be made up of axle sleeve 8, bulb 9, leg 10 and wavy surface 11, the center pit of axle sleeve 8 is axis hole 8a, and at the middle part of axle sleeve 8, radially symmetry offers pin-and-hole 8b.When needing to detect the verticality between gear shift fork axis hole 8a and pin-and-hole 8b, first gear shift fork is placed on base plate 1, locating shaft 2 is passed from the axle sleeve 8 of gear shift fork, then gear shift fork is rotated, make the detect aperture on the pin-and-hole 8b aligning locating shaft 2 on gear shift fork axle sleeve 8, then latch 5 is promoted, latch 5 is moved towards the direction of locating shaft 2, if the minimal segment of latch 5 can through the detect aperture on the pin-and-hole 8b of axle sleeve 8 side and locating shaft 2, pass from the pin-and-hole 8b of axle sleeve 8 opposite side, verticality then between this gear shift fork axis hole 8a and pin-and-hole 8b meets the requirements.
