Description
Technical field
The utility model belongs to special purpose machine tool technological equipment manufacturing technology field, particularly relates to the anchor clamps of automobile synchronizer speed changer tooth hub boring.
Background technology
Along with China's economic development, automobile becomes important traffic and means of transport.In auto manufacturing, automotive transmission is indispensable parts, and wherein synchronizer of automobile transmission tooth hub is processed with its particularity.Adding man-hour at drilling machine, generally is to bore a hole clamping once, process a finished product and want clamping three times, and quality can not be guaranteed, and labor strength is large, and clamping times is many, and upper batch production becomes tight slightly operation.
The utility model content
The utility model purpose: the purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of simple in structure, as long as clamped one time just can be processed three holes, the location reliably, easy to use and brill synchromesh gear hub three hole clamp mechanisms that machining accuracy is high.
Technical scheme: in order to solve the problems of the technologies described above, a kind of brill synchromesh gear hub three hole clamp mechanisms described in the utility model, comprise noumenal seat, body is installed on the noumenal seat, and axle wears in the noumenal seat from body top, workpiece spindle is connected with axle, index plate is arranged between axle and the body, and the one side is provided with pin, and stationary cam and rotating cam are arranged in the noumenal seat, and be sleeved on the described axle, described rotating cam is connected with cam handle.
Be provided with the drill bushing seat in described workpiece spindle one side, drill bushing this drill bushing seat of packing into.
Described stationary cam is connected locking nut and is connected with axle with rotating cam.
Described workpiece spindle is connected with axle by housing screw and opening pad.
Be provided with the groove that cooperates with pin at described index plate.
One end of described pin is connected with spring.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: because that the symmetry in synchromesh gear hub three holes requires is high.Realize the part by one-step clamping, only needed to rotate index dial and just can easily process another hole, thereby greatly improved production efficiency, guaranteed the quality of product.The utility model adopts the special fixture scheme, and is not only simple in structure, is easy to assembling, with low cost, and operation, use, easy to adjust, and machining accuracy is high, can effectively reduce labor strength.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, workpiece; 2, drill bushing seat; 3, drill bushing; 4, spring base; 5, spring; 6, pin; 7, stationary cam; 8, rotating cam; 9, housing screw; 10, opening pad; 11, workpiece spindle; 12, axle; 13, index plate; 14, body; 15, cam handle; 16, locking nut; 17, noumenal seat.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, these brill synchromesh gear hub three hole clamp mechanisms comprise noumenal seat 17, body 14 is installed on the noumenal seat 17, axle 12 wears in the noumenal seat 16 from body 14 tops, workpiece spindle 11 is connected with axle 12, workpiece 1 cooperates housing screw 9 and opening pad 10 and above-mentioned workpiece spindle 11 fastening, also be provided with drill bushing seat 2 in described workpiece spindle 11 1 sides, drill bushing 3 this drill bushing seat 2 of packing into, by drill bushing 3 guiding drill bit centering workpiece 1, guarantee the machining accuracy of product, boost productivity, reduce workman's requirement.Index plate 13 is arranged between axle 12 and the body 14, and the one side is provided with pin 6, is provided with the groove that cooperates with pin 6 at described index plate 13.One end of described pin 6 is connected with spring 5, and this spring 5 is installed in the spring base 4.Stationary cam 7 and rotating cam 8 are arranged in the noumenal seat 17, be sleeved on the described axle 12, and fastening by locking nut 16, described rotating cam 8 is connected with cam handle 15.
During work, unclamp housing screw 9, take down opening pad 10, load onto workpiece 1 with tooth hub three-flute and Internal hole positioning, be loaded on opening pad 10, lock-screw 9 such workpiece are finished with regard to clamping.Deng a hole drill good after, rotating cam handle 15, driving rotating cam 8 unclamps, mandrel 12 again, pin 6 automatic clampings are in the groove of index plate 13, rotating cam handle 15 drives rotating cams 8 and locks again, so just can process another hole.
The above only is preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
