Abstract
The utility model provides a hub valve hole punching positioning device. The device comprises a positioning head (1), a sleeve rod (2), a bolt (3) and a spring (4), wherein a square groove (11) is formed on the positioning head (1); the positioning head (1) is cylindric; a buffer cambered surface (12) is formed on the positioning head; the sleeve rod (2) is formed by a sleeve (21) and a positioning rod (22); the positioning rod (22) is formed above the sleeve (21); the upper part of the positioning head (1) is inserted and sleeved in the sleeve (21); the bolt (3) is connected on the sleeve (21) and the front end of the bolt is compressed in the square groove (11) on the positioning head (1); the spring (4) is inserted and sleeved in the positioning head (1); and one end of the spring (4) applies force to the positioning head (1) and the other end thereof applies force to the sleeve rod (2). The device has the following beneficial effects that: the device can reasonably position the hub and ensure the drill bit to punch the valve hole in the absolutely central position of the hub valve hole.
Description
Technical field:
The utility model relates to the wheel hub production technical field, inflates before the aperture of door wheel hub positioner of use more specifically to wheel hub.
Background technology:
After the aluminium alloy wheel hub castings production is accomplished; The aluminum alloy wheel hub casts need utilize the punching drilling machine to come the valve port place punching to the aluminum alloy wheel hub casts; During punching, be that manual work is placed into the aluminum alloy wheel hub casts on the workbench of punching drilling machine, and then cooperate the pulling claw clamping and positioning again through the manual location of manual work; With the aluminium alloy wheel hub positioning and fixing on the punching Drilling machines bench, and then the punching of the drill bit through drilling machine.Its weak point is: locate the aluminum alloy wheel hub casts like this, owing to adopt artificial location, cooperate the pulling claw clamping and positioning again, being prone to cause the valve port of being up to not is definitely in the center.General wheel hub order client is not very high to the status requirement of the valve port centre bore of wheel hub, so the method that aperture of door is inflated in this location can satisfy most wheel hub order requirement of client.And resemble the wheel hub of Bayerische Motorne Werke Aktiengeellschaft's demand, and the position of valve port there is very strict requirement, if go punching by prior art location aluminium alloy wheel hub again, then be prone to cause the valve port of being up to, thereby form substandard products not in the center.
The utility model content:
The purpose of the utility model is exactly the deficiency to prior art, and a kind of wheel hub valve port punching positioner is provided, and it can use wheel hub to navigate to rational position, lets the drilling machine drill bit get valve port in position, absolute center, wheel hub valve port place.
The technological solution of the utility model is following:
Wheel hub valve port punching positioner, it is made up of positioning head, loop bar, screw and spring, forms square groove on the positioning head, positioning head be cylindric and its on form the buffering cambered surface;
Loop bar is made up of sleeve and backstay, and upper cartridge forms backstay;
The top sleeve of positioning head is in sleeve, and screw is screwed onto on the sleeve and front end is pressed in the square groove on the positioning head, and the spring sleeve is in positioning head, and spring one end active force acts on power in loop bar in positioning head, the other end.
It is protruding to form ring on the said backstay, encircles the clamping that forms two positioned opposite on protruding and parallel and uses the plane.
The beneficial effect of the utility model is:
It can use wheel hub to navigate to rational position, lets the drilling machine drill bit get valve port in position, absolute center, wheel hub valve port place.

Among the figure: 1, positioning head; 11, square groove; 12, buffering cambered surface; 2, loop bar; 21, sleeve; 22, backstay; 23, ring is protruding; 231, the plane is used in clamping; 3, screw; 4, spring.
The specific embodiment:
Embodiment: see shown in Fig. 1 to 4, wheel hub valve port punching positioner, it is made up of positioning head 1, loop bar 2, screw 3 and spring 4, forms square groove 11 on the positioning head 1, positioning head 1 for cylindric and its on form and cushion cambered surface 12;
The top sleeve of positioning head 1 is in sleeve 21, and screw 3 is screwed onto on the sleeve 21 and front end is pressed in the square groove 11 on the positioning head 2, and spring 4 sleeves are in positioning head 1, and spring 4 one end active forces act on power in loop bar 2 in positioning head 1, the other end.
It is protruding 23 to form ring on the said backstay 22, encircles the clamping that forms two positioned opposite on protruding 23 and parallel with plane 231.
Operation principle: see Fig. 5,6, shown in 7, have only last half valve port 51 on the aluminum alloy wheel hub casts 5, when aluminum alloy wheel hub casts 5 bores valve port, earlier aluminum alloy wheel hub casts 5 is placed on the workbench of drilling machine.
The utility model is to be fixed on the drilling attachment of rotary drilling cephalic disc of drilling machine; When moving downward under the driving of drilling attachment at cylinder; Along with positioning head 1 slowly moves downward; Aluminum alloy wheel hub casts 5 buffering cambered surface 12 with on run to rational position automatically under the contact-making surface extruding force effect of half valve port 51; Accomplish when being inserted into last half valve port, 51 foots when positioning head 1, aluminum alloy wheel hub casts 5 navigates to the position that can be beaten the centermost hole by drill bit naturally, with the pulling claw clamping aluminum alloy wheel hub casts 5 is fixed tightly on the workbench then; Just can the rotary drilling cephalic disc, utilize the drill bit on the drill bit dish exactly the center that valve port is drilled in last half valve port 51 to be formed valve port as shown in Figure 8.
Clamping with plane 231 makes things convenient for drilling attachment to clamp loop bar 2; Positioning head 1 is fixed together through screw 3 and loop bar 2, is to change positioning head 1 for ease, in the time need boring valve port to the wheel hub of different model; Just can in time change positioning head 1, remove to locate the wheel hub of different model.
