Embodiment
The technical solution of the utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
Referring to the clamping device shown in Fig. 1 to 6, it includes fixed seat 1, slidably the first clamping in fixed seat 1
The grip slipper 3 of seat 2 and second, the first clamping 4 being detachably arranged on the first grip slipper 2, it is detachably arranged at the second grip slipper 3
On the second clamping 5, there is in the first clamping 4 first clamp port 4a, there is the second clamp port 5a, the first folder in the second clamping 5
Hold mouthful 4a it is relative with the second clamp port 5a oral area and both be engaged the clamping that can be circumferentially formed to bent axle 10.First folder
It is in the V-type mouth with radian to hold mouthful 4a and the second clamp port 5a, and both, which are engaged, can form to bent axle 10 well to stablize
Grip.
When being clamped to bent axle 10, the first clamp port 4a two sides are respectively with being clamped connecing for shaft part on bent axle 10
Contacting surface is tangent, and the axial line of the intersection point of two tangent tangent line vertical lines and above-mentioned clamped shaft part is located at sustained height position；The
Two clamp port 4a two sides are also tangent with the contact surface of clamped shaft part on bent axle 10 respectively, and two tangent tangent line vertical lines
The axial line of intersection point and above-mentioned clamped shaft part is also at sustained height position.
When different parts on to bent axle 10 are clamped or different bent axles 10 is clamped, it is only necessary to for bent axle
The size and shape of shaft part to be held changes the first clamping 4 with different clamp port 4a, 5a with the second clamping 5 i.e. on 10
Can.Specifically, the clamping 5 of the first clamping 4 and second can be detachably connected to the first grip slipper 2 and second respectively by screw
On grip slipper 3.
The clamping device also include be used for drive the first grip slipper 2 and the second grip slipper 3 synchronously move toward one another with to song
The clamping drive mechanism 7 that axle 10 is clamped.Shown in Figure 3, the clamping drive mechanism 7 includes being fixedly arranged on the first grip slipper 2
First rack 71 of bottom, the second rack 72 for being fixedly arranged on the bottom of the second grip slipper 3, can rotatably it be located at admittedly around Pivot Point Center line
Gear 73 in reservation 1, the gear 73 is along the vertical direction between the first rack 71 and the second rack 72, and gear 73 is simultaneously
It is meshed with the first rack 71, the second rack 72.
Referring to shown in Fig. 1 to Fig. 3, the clamping drive mechanism 7 also includes being used to drive the first grip slipper 2 to slide along direction
Slide and the clamping actuator 6 of clamping force be provided, herein, the clamping actuator 6 use for double-acting type oil cylinder.The oil cylinder 6
Including cylinder body 61 and piston rod 62, cylinder body 61 is regularly located in fixed seat 1 and the external part of piston rod 62 and the first grip slipper 2
It is fixedly connected.When the opposing cylinder 61 of piston rod 62 stretches out, piston rod 62 promotes the first grip slipper 2 to slide along direction towards the
Two grip slippers 3 slide, and the first rack 71 is synchronized with the movement and drives gear 73 to rotate, so as to drive the second rack 72 towards the first tooth
Bar 71 moves and drives the second grip slipper 3 to be moved towards the first grip slipper 2, and then make it that the first clamping 4 and the second clamping 5 are opposite
Move and realize the fixed clamp to bent axle 10.When the opposing cylinder 61 of piston rod 62 is retracted, then the first grip slipper 2 and second presss from both sides
Seat 3 is held synchronously to move in the opposite direction so as to unclamp the clamping to bent axle 10.
In above process, because the first rack 71 engages with the second rack 72 with gear 73, the first grip slipper 2 and
The move toward one another of two grip slipper 3 and both slide displacement is consistent, the first clamping 4 and the second clamping 5 keep synchronous opposite
Move and bent axle 10 is clamped, or keep synchronous opposite direction to move and unclamp the clamping to bent axle 10.
Referring to shown in Fig. 1 to Fig. 6, fixed seat 1 is the body structure with host cavity, the first rack 71, the second rack 72
And gear 73 is housed in the host cavity of above-mentioned body structure.Specifically, the fixed seat 1 includes base 11, is fixedly arranged on base
Two guide holders 12 of 11 left and right sides, formed between two guide holders 12 and base 11 to the first grip slipper 2 and the second folder
Hold the guide slide that seat 3 carries out slide-and-guide.
Herein, the top of the opposite flank of two guide holders 12 is equipped with tapered ramp so that the top shape of guide slide
The guide frame trapezoidal into section, the bottom of the first grip slipper 2, the second grip slipper 3 bottom respectively have can with it is above-mentioned
The slide portion for the oat tail groove structure that guide frame is slidingly fitted.By taking the slide portion 31 of the bottom of the second grip slipper 3 as an example, referring to figure
Shown in 5, the two sides in the slide portion 31 are tapered ramp, and the wherein one side in the slide portion 31 and respective side guide holder 12
Inclined-plane be slidingly fitted and formed to its slide-and-guide.Using such structure not only relatively simple convenience of structure setting, and
And it can also be formed to the first grip slipper 2 and the second grip slipper 3 with stable guiding.
Join each accompanying drawing to show, also regularly set at the top of guide holder 12 on the first grip slipper 2, on the second grip slipper 3
Be equipped with the baffle plate blocked, so can effectively prevent foreign matter drop fixed seat 1 guide slide in and influence clamp driving machine
The normal operation of structure 7.
It is shown in Figure 4, when the clamping device is used to clamp bent axle 10, it usually needs use, that is, use in pairs
Preceding shaft part 101, the rear shaft part 102 using another stack clamping device clamping bent axle 10 of one stack clamping device clamping bent axle 10, two
On individual clamping device the structure of the first clamping 4 and the second clamping 5 then respectively according to the size of preceding shaft part 101 and rear shaft part 102 and
Shape is chosen installation.
When being clamped to bent axle 10, the centre that support base 20 is supported on bent axle 10 can be first passed through, and causes preceding shaft part 101
With the position to be held on rear shaft part 102 respectively between the corresponding clamping 5 of first clamping 4 and second, two oil are then driven
Cylinder 6 moves simultaneously, and after realizing that the synchronous clamping to preceding shaft part 101 and rear shaft part 102, bent axle 10 are clamped, preceding shaft part 101 is with after
The axial line of shaft part 102 can be maintained on same axial line, when being drilled to bent axle 10 and the processing such as end face processes, energy
Enough obtain preferable machining accuracy.
To sum up, clamping device of the present utility model, it can be realized effectively clamps to the stabilization of axial workpiece, for not
During with the bent axle 10 of size or shape, also only need to select the first corresponding clamping 4 and the second clamping 5 to give installation,
Production cost is so greatly reduced compared to existing technologies, is shortened the manufacturing cycle of product, has also been effectively saved sky
Between, there is good practicality.
For above-described embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with technique
Personage can understand content of the present utility model and implement according to this, the scope of protection of the utility model can not be limited with this.
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover the scope of protection of the utility model it
It is interior.
