Description

The bowl-shape Workpiece clamping device of bottom of which has holes
Technical field
The utility model relates to a kind of clamping device, is specifically related to a kind of bowl-shape Workpiece clamping device of bottom of which has holes.
Background technology
Clamping device is important process equipment indispensable in machinery manufacturing industry, can guarantee mechanical processing quality, enhances productivity, reduces production costs, reduce labor intensity.The kind of fixture can be designed to various for workpiece kind, application target, environment for use etc.
For the bowl-shape workpiece of bottom of which has holes, existing clamping device does not have stable impetus at the bowl-shape surface of the work of bottom of which has holes, so it is often unstable to clamp this workpiece.
Utility model content
The defect existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of bowl-shape Workpiece clamping device of bottom of which has holes, and this clamping device can be by the bowl-shape workpiece location of bottom of which has holes stably clamping.
For achieving the above object, the technical solution of the utility model is: the bowl-shape Workpiece clamping device of bottom of which has holes, comprise pedestal and be vertically fixed on the cylinder on pedestal, wherein, also be provided with post wedge, plunger, positioning screw and back-moving spring, described post wedge and pedestal are vertically slidably connected, the piston rod clamping of post wedge lower end and cylinder, upper end inclined-plane is circumferentially set; Described plunger is provided with the clamping limb of the bowl-shape workpiece inwall that coordinates bottom of which has holes, described post wedge both sides are equipped with described plunger, and plunger and pedestal are slidably connected, and inclined-plane, Yu Zhuxie upper end, plunger one end coordinates, the other end is connected with back-moving spring, and the described back-moving spring other end is connected on pedestal; Described positioning screw is axially set in the center of post wedge upper end along post wedge, and positioning screw upper end is provided with clamp nut.
While adopting technique scheme, the bowl-shape workpiece openings of bottom of which has holes down, and screw rod is inserted in the hole of bottom, screw rod upper end with clamp nut by the bowl-shape Work-sheet pressing of bottom of which has holes, Compressed Gas is entered in control cylinder lower end, the piston rod of cylinder protrudes upward, on drive post wedge, move, plunger inclined-plane cooperation due to Yu Qi both sides, post wedge upper end, so post wedge promotes two plungers to two plunger outward sides respectively, the clamping limb of two plungers is from two relative position application of forces of the bowl-shape workpiece inwall of bottom of which has holes, thereby by the bowl-shape piece-holder of bottom of which has holes.The utility model can be by the bowl-shape workpiece location of bottom of which has holes stably clamping.
Further, between described post wedge lower end and piston rod for intermittently coordinating, after the bowl-shape workpiece of bottom of which has holes is clamped, post wedge is stuck between two plungers, piston rod and post wedge shackle portion have intermittently, and piston rod coupled columns wedge has larger impulsive force, and post wedge is easily deviate from.
Further, the inclined-plane of described post wedge upper end is provided with wearing layer, and the inclined-plane of post wedge upper end and the friction of the plunger of both sides are frequent, easily weares and teares in post wedge upper end, and wearing layer is the service life of extended column wedge effectively.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the bowl-shape Workpiece clamping device embodiment of the utility model bottom of which has holes.
The specific embodiment
As shown in Figure 1, a kind of bowl-shape Workpiece clamping device of bottom of which has holes, comprise pedestal 3 and be vertically fixed on the cylinder on pedestal 3, wherein, also be provided with post wedge 2, plunger 4, positioning screw 5 and back-moving spring 6, post wedge 2 is vertically slidably connected with pedestal 3, piston rod 1 clamping of post wedge 2 lower ends and cylinder, upper end inclined-plane 21 is circumferentially set; Plunger 4 is provided with the clamping limb 41 of bowl-shape workpiece 7 inwalls that coordinate bottom of which has holes, post wedge 2 both sides are equipped with plunger 4, and plunger 4 is slidably connected with pedestal 3, and plunger 4 one end coordinate with post wedge 2 inclined-planes, upper end, the other end is connected with back-moving spring 6, and back-moving spring 6 other ends are connected on pedestal 3; Positioning screw 5 is axially set in the center of post wedge 2 upper ends along post wedge 2, and positioning screw 5 upper ends are provided with clamp nut.
In the present embodiment, between post wedge 2 lower ends and piston rod 1 for intermittently coordinating, after the bowl-shape workpiece 7 of bottom of which has holes is clamped, post wedge 2 is stuck between two plungers 4, piston rod 1 has intermittently with post wedge 2 shackle portion, and piston rod 1 coupled columns wedge 2 has larger impulsive force, and post wedge 2 is easily deviate from.The inclined-plane 21 of post wedge 2 upper ends is provided with wearing layer, and plunger 4 frictions of the 21Yu both sides, inclined-plane of post wedge 2 upper ends are frequent, easily weares and teares in post wedge 2 upper ends, and wearing layer is the service life of extended column wedge 2 effectively.
Specific works flow process:
As shown in Figure 1, the bowl-shape workpiece 7 of bottom of which has holes is opening down, and screw rod is inserted in the hole of bottom, screw rod upper end compresses the bowl-shape workpiece of bottom of which has holes 7 with clamp nut, Compressed Gas is entered in control cylinder lower end, the piston rod 1 of cylinder protrudes upward, on drive post wedge 2, move, plunger 4 inclined-planes cooperations due to post wedge 2 Yu Qi both sides, upper end, so post wedge 2 promotes two plungers 4 laterally to two plungers 4 respectively, the clamping limb 41 of two plungers 4 is from two relative position application of forces of bowl-shape workpiece 7 inwalls of bottom of which has holes, thereby by 7 clampings of the bowl-shape workpiece of bottom of which has holes, now, back-moving spring 6 is compressed.Compressed Gas is entered in control cylinder upper end, the piston rod 1 of cylinder shrinks downwards, the downward impact pole wedge 2 of piston rod 1 of cylinder, post wedge 2 is deviate from and moves down from 4 of two plungers, plunger 4, under the restoring force of back-moving spring 6, moves to the inside, thereby the bowl-shape workpiece 7 of bottom of which has holes is unclamped, unclamp clamp nut, can take off the bowl-shape workpiece 7 of bottom of which has holes.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
