Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
As shown in Figure 1 to Figure 3, the fixed device of a kind of screw tap, including shell 1, the 1 inside front and back of shell be symmetrically arranged with every
Plate 11 is symmetrically arranged with clamping device in shell 1, and the clamping device is set between 1 inner wall of partition 11 and shell, the partition 11
Between be equipped with transmission component, cover board 13 is equipped at the top of the shell 1, is symmetrically arranged with mounting table 4 before and after 13 upper surface of cover board.
Workpiece to be processed is placed on mounting table 4, after starting transmission component, control clamping device is clamped fixation to workpiece,
After the location of workpiece has been fixed, chasing bar 5 can be used, tapping is carried out to workpiece.It include two clamping devices in the present apparatus,
Two workpieces processings can be fixed simultaneously, the time of processing can be saved in this way.
The clamping device includes rotation axis 33, and 33 left and right ends of rotation axis are symmetrically connected with screw rod 31, the silk
The outer end of bar 31 and 1 inner wall of shell are rotatablely connected, and the screw rod 31 is equipped with T-type sliding block 32, the T-type sliding block 32 and screw rod 31
It is threadedly engaged connection, 32 bottom surface of T-type sliding block is connect with 1 inner wall basal sliding of shell, is connected with cone in the rotation axis 33
Gear 1.When bevel gear 1 rotates, since bevel gear 1 and rotation axis 33 are affixed, therefore rotation axis 33 will drive
It rotates, because screw rod 31 is connect with rotation axis 33, and is symmetrically set in 33 both ends of rotation axis, so the screw rod at 33 both ends of rotation axis
31 is oppositely oriented, therefore when rotation axis 33 rotates, screw rod 31 rotates in same direction with rotation axis 33, is cooperatively connected with screw rod 31
T-type sliding block 32 is moved with the rotation of screw rod 31, because the screw rod 31 at 33 both ends of rotation axis is oppositely oriented, two
Upper 32 direction of motion of T-type sliding block of bar 31 is opposite and rate is identical.When two T-type sliding blocks 32 move toward one another gradually to workpiece into
Row clamps.
The transmission component includes worm gear shaft 24, and worm gear 22, the both ends point of worm gear shaft 24 are equipped in the middle part of the worm gear shaft 24
Not Chuan Guo corresponding partition 11, and with partition 11 be rotatablely connected, the both ends of worm gear shaft 24 are equipped with bevel gear 2 25, the cone tooth
It takes turns 2 25 to be cooperatively connected with bevel gear 1, is symmetrically arranged with support plate 12 between the partition 11, is rotated in the support plate 12
It is connected with worm screw 21, the worm screw 21 is cooperatively connected with worm gear 22, and one end of worm screw 21 is connected with motor 23.When motor 23 starts
When, the cooperation of 22 worm screw 21 of worm gear moves, and worm gear 22 drives the bevel gear 2 25 at 24 both ends of worm gear shaft to rotate, due to cone
Gear 2 25 and bevel gear 1 are cooperatively connected, and when bevel gear 2 25 rotates, can rotate with dynamic bevel gear 1, therefore when electricity
After machine 23 starts, clamping device is started to work, and is driven using 22 worm screw 21 of worm gear, there is very big transmission ratio, and two-wheeled engaging tooth
It is contacted between face for line, bearing capacity is higher, and the transmission of worm screw 21 is equivalent to worm drive, is driven, therefore is driven flat for multi-tooth meshing
Surely, noise very little, the transmission of 22 worm screw 21 of worm gear have self-locking performance, when the equivalent that the lead angle of worm screw 21 is less than engagement wheel between cog rubs
When wiping angle, mechanism has self-locking performance, it can be achieved that reverse self-locking, i.e., can only drive worm gear 22 by worm screw 21.When motor 23 stops turning
After dynamic, since the transmission of 22 worm screw 21 of worm gear has self-locking performance, so bevel gear 1 and bevel gear 2 25 can not be freely rotated,
T-type sliding block 32 cannot also move freely, in this way after completing to the clamping of workpiece, as long as motor 23 does not invert, and workpiece
It will not loosen, without specially being positioned to T-type sliding block 32.
In order to adapt to the different size of workpiece to be processed, be equipped with snap-gauge 34 at the top of the T-type sliding block 32, the snap-gauge 34 with
13 lower surface of cover board is slidably connected, and sliding slot 14 is symmetrically arranged on the cover board 13, and 32 top of T-type sliding block and sliding slot 14 slide
Connection when only snap-gauge 34 and work piece interface are long-pending larger, just can guarantee clamping more when snap-gauge 34 is clamped workpiece
Fastening.
When chasing bar carries out tapping to workpiece, pressure can be generated to workpiece, this pressure may cause workpiece in card
It is moved between plate 34, workpiece is influenced to move by pressure in order to prevent, and limiting device, institute are equipped on mounting table 4
Stating limiting device includes limit plate 43, and 43 bottom of limit plate is equipped with rectangle slide bar 42, is equipped with rectangle sliding slot inside the mounting table 4
41, the rectangle slide bar 42 is slidably connected with rectangle sliding slot 41, sliding in rectangle in order to which the position to rectangle slide bar 42 is fixed
41 upper surface of slot is equipped with fastening bolt 44, and the fastening bolt 44 is cooperatively connected with rectangle slide bar 42, when 42 position of rectangle slide bar
After determination, rotation fastening bolt 44 positions rectangle slide bar 42, prevents rectangle slide bar 42 from moving freely.
The utility model discloses a kind of fixed devices of screw tap, can be simultaneously to two by 22 worm screw 21 of worm gear cooperation transmission
Workpiece is positioned, and workpiece to be processed is placed on mounting table, start transmission component after, control clamping device to workpiece into
Row steps up to fix, and after the location of workpiece has been fixed, chasing bar 5 can be used and carry out tapping to workpiece.It include two in the present apparatus
A clamping device can simultaneously be fixed two workpieces processings, can save the time of processing in this way.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed by the utility model, this
For the technical staff in field according to disclosed technology contents, not needing creative labor can be special to some of which technology
Sign makes some simple modification, equivalent change and modifications, belongs to the range of technical solutions of the utility model.
