Activity orientation.
Summary of the invention
The purpose of the utility model is to provide a kind of to need to carry out in advance each point of part of vehicle body before fine positioning
The part pre-compressing device of compression.
To achieve the above object, part pre-compressing device designed by the utility model include clamping nut, threaded sleeve,
Compressed spring, head part pin and fine positioning locating piece, the clamping nut spiral are fixed on the internal screw thread of described threaded sleeve one end
Kong Zhong, the head part pin and the compressed spring are placed in the hollow cavity of the threaded sleeve, the minor diameter end of the head part pin
End is stretched out from the pin hole of the threaded sleeve other end, and the threaded sleeve spiral is mounted on the fine positioning locating piece
In thread bush pore.
Preferably, it is twisted outside part of the threaded sleeve beyond the thread bush pore on the fine positioning locating piece
Tightly there is pressure nut, the lower end surface of the pressure nut is abutted with the upper surface of the fine positioning locating piece.
Preferably, the threaded sleeve protrudes into the part of the thread bush pore on the fine positioning locating piece
Length be less than the thread bush pore length.
Preferably, the head part pin can be fully retracted to the thread bush pore of the fine positioning locating piece
It is interior.
The beneficial effects of the utility model are: part is in centering after using the part pre-compressing device of the utility model
The end elder generation of head part pin and feature contacts, guarantee part is in essence under the action of the elastic force of head part pin is supplied to by compressed spring
Positioning before always be in preloading condition so that part be unlikely to premature contact to fine positioning locating piece and cause part deformation or
Surface scratching.

Each part numbers are as follows in figure: part pre-compressing device 10 (wherein, clamping nut 1, threaded sleeve 2, pressure nut
3, compressed spring 4, head part pin 5, fine positioning locating piece 6)；Erection support 20, part 30.
Specific embodiment
It is described in further detail below in conjunction with details of the drawings and specific embodiments to the utility model.
Fig. 1, Fig. 2, Fig. 3 and Fig. 4 are please referred to, the part pre-compressing device 10 that the utility model is preferably implemented includes compressing spiral shell
Cap 1, threaded sleeve 2, pressure nut 3, compressed spring 4, head part pin 5 and fine positioning locating piece 6,1 spiral of clamping nut are fixed on
One end (upper end) of threaded sleeve 2, head part pin 5 and compressed spring 4 are placed in the hollow cavity of threaded sleeve 2, head part pin 5 it is small straight
Diameter end is stretched out from the pin hole of 2 other end of threaded sleeve (lower end) under the resilient force of compressed spring 4, threaded sleeve 2
Spiral is mounted in the thread bush pore on fine positioning locating piece 6.Threaded sleeve 2 is beyond the thread bush on fine positioning locating piece 6
The part of pore is compressed by pressure nut 3.
Above-mentioned part pre-compressing device 10 in fine positioning locating piece 6 by screwing in threaded sleeve 2 and passing through pressure nut 3
It compresses locking, head part pin 5 and compressed spring 4 is put into threaded sleeve 2, then by clamping nut 1 by head part pin 5 and compressed spring
4 enclose wherein and compress.The length that threaded sleeve 2 protrudes into the part of the thread bush pore on fine positioning locating piece 6 is less than screw thread
The length of collar aperture, the i.e. lower end of threaded sleeve 2 are non-bulging in thread bush pore.It is fixed that head part pin 5 can be fully retracted to fine positioning
In the thread bush pore of position block 6.
Fig. 5 and Fig. 6 are please referred to, two group part pre-compressing devices 10 are fixed on erection support 20, real to part 30
Existing pre-pressing.Under the guidance that two sides are oriented to when centering, the end of head part pin 5 is first contacted with part 30 part 30, passes through compression
Spring 4 guarantees that part 30 is in preloading condition always before fine positioning under the action of being supplied to the elastic force of head part pin 5, so that zero
Part 30, which is unlikely to premature contact, leads to the deformation or surface scratching of part 30 to fine positioning locating piece 6.
The part pre-compressing device of the utility model is suitable for the pre-pressing of sheet parts, fixed in pressing essence for part
Pre-pressing before position can effectively prevent part because directly deforming caused by contact compact heap.
