Abstract

The utility model provides a subpressure type combined clamp device, which relates to the light-duty manufacture field, and comprises a worktable and a clamp table. At least one clamp table is arranged on the worktable; the upper part of the clamp table is provided with a gridding-shaped vacuum tank; the bottom of the clamp table is provided with aeration pipelines, and each pipeline is communicated with at least a vacuum tank; the aeration pipelines are connected with each other and are connected with a subpressure device through air inlet pipelines. The commonality of the clamp device is solved after adopting the structure, workpieces with linear and nonlinear multiple-dimension forms can be effectively clamped, and the labor intensity of workers and the cost of a corporation are reduced.

Description

A kind of suction type combination clamping device
Technical field
The utility model belongs to light-duty manufacture field and relates to a kind of clamping device, is specifically related to a kind of suction type combination clamping device of non-linear type body processing.
Background technology
In large-sized processing equipments such as lathe, clamping device a kind of equipment that is absolutely necessary, play the effect that the location that processes raw material is clamped, to guarantee the accuracy of processing, existing large-scale clamping device mostly is manual clamping mode because of being subjected to the restriction of clamp base, promptly adopts the fixing mode of screw that machined object is fixed on the base, operating automation degree is low like this, and labour intensity is big.And this kind clamping device only can be used for one, the processing of two kind of part clamps, if the product change then need be changed clamping device, so existing clamping device versatility is poor, and serious waste phenomenon, and increased and process the required time, be unfavorable for large-scale processing.
For nonlinear workpiece because its shape is lack of standardization, can't be with the clamping of existing clamping device, need adopt special clamping tool man-hour adding, and ten minutes is loaded down with trivial details during assembling, can make the product processed precise decreasing simultaneously, even cause waste product, bring a large amount of losses to enterprise.
Summary of the invention
Problems at existing clamping device existence, for adapting to the use of various main equipments, the utility model provides a kind of brand-new suction type combination clamping device, it adopts the method for negative pressure that workpiece is fixed on the workbench, adopt the versatility that has improved clamping device behind the device of this structure, make that the workpiece of linearity and non-linear multidimensional body is effectively clamped, reduced the cost of working strength of workers and enterprise.
The concrete technical scheme that the utility model adopts is: it comprises workbench and clamps platform, at least one is installed on the workbench clamps platform, latticed vacuum tank is arranged at the top that clamps platform, and the bottom that clamps platform has vent line, and every pipeline all is communicated with at least one vacuum tank; Vent line is connected to each other and is connected with negative pressure device by air inlet pipeline.
After adopting this structure, add linear or nonlinear workpiece to be placed on man-hour and clamp on the platform, workpiece is closely contacted with the clamping platform, be placed with seal in the vacuum tank of clamping platform and workpiece contact portion, the general sealing strip that adopts, contacted each other sealing strip closely connects, and forms an airtight cavity between platform and workpiece bottom surface and is isolated with the external world clamping, and guarantee to have in the interior vacuum tank of this cavity the mouth of pipe of at least one vent line; Negative pressure device that this moment, employing added such as air compressor machine etc. vacuumize by air inlet pipeline and vent line, make and become negative pressure or vacuum environment in the cavity, workpiece can begin the processing to workpiece afterwards being pressed on the clamping platform under the atmospheric effect and being positioned at this moment.
Because vacuum tank is latticed layout, intersect each other, therefore can be according to the shape of workpiece bottom, surround variform cavity with seal, so just go for nonlinear workpiece, reached the versatility of equipment, and because what adopt is vacuum suction, so its effect is more obvious than the effect that adopts mechanical grip.
In order to reach best adsorption effect, generally sealing strip is placed in the contact-making surface outermost one the circle vacuum tank in, its cavity area maximum that surrounds like this, the maximum final adsorption effect of the strength of absorption is best, particularly clamp, adopt this large-area vacuum cavity can reach the purpose of firm and clamping work pieces for large-scale workpiece.For general workbench, a plurality of such clamping platforms can be set on its table top, so just go for the workpiece of different shape, adsorbed the location according to the size of workpiece and the position of needs processing thereof; The vent line that clamps in the platform can be connected as a single entity each other, and entire equipment just only needs a negative pressure equipment to use like this, greatly reduces production cost.For some special process equipments, latticed vacuum tank can directly be set on its workbench, so just can save the clamping platform, and can be according to the placement location of workpiece, the cavity shape and the size of the placement location arbitrary combination its underpart by adjusting sealing strip clamp dynamics for different processing requests provides different absorption, and can increase the versatility of equipment like this, do not need that each is clamped platform and regulate, reduced the step of work.
Adopting the clamping device of this structure, it is simple in structure, realized the many usefulness of one, and its adsorption range great dynamics for workpiece is strong; Because the cavity during its absorption is combined as different shapes arbitrarily, has high equipment interoperability, can be with linear, firm being adsorbed on the workbench of non-linear multidimensional body workpiece, substitute traditional pressing plate clamping mode, more convenient and can realize adsorbing the Long-distance Control of work during operation, it is long to solve the large-scale non-linear multidimensional body parts fixation time, labour intensity is big, the frock manufacture difficulty is big, practical problems such as manufacturing cost height, alleviate working strength of workers greatly, also alleviated the production cost of enterprise.

Fig. 2 is the structural representation that clamps platform in the clamping device;
When being duty, Fig. 3 clamps the cut-away view of platform arbitrarily;
1 workbench among the figure, 2 clamp platform, 3 vent lines, 4 clamp the platform table top, 5 horizontal vacuum tanks, 6 vertical vacuum tanks, the 7 ventilation mouths of pipe, 8 sealing strips, 9 workpiece, 10 connecting lines.
The specific embodiment
The suction type combination clamping device that the utility model provides comprises workbench 1 and clamps platform 2, at least one is installed on the workbench 1 clamps platform 2, latticed vacuum tank 5 and 6 are arranged at the top that clamps platform 2, the bottom that clamps platform 2 has vent line 3, and every pipeline all is communicated with at least one vacuum tank; Vent line 3 is connected to each other and is connected with negative pressure device by air inlet pipeline 10.
Add linear or nonlinear workpiece 9 to be placed on man-hour and clamp on the platform 2, workpiece 9 is closely contacted with clamping platform 2, be placed with sealing strip 8 in the vacuum tank of clamping platform 2 and workpiece 9 contact portions, contacted each other sealing strip closely connects, form an airtight cavity between platform 2 and workpiece 9 bottom surfaces and be isolated clamping, and guarantee to have in the interior vacuum tank of this cavity the mouth of pipe 7 of at least one vent line with the external world; Negative pressure device that this moment, employing added such as air compressor machine etc. vacuumize by air inlet pipeline 10 and vent line 3, make and become vacuum environment in the cavity and become a vacuum cup, workpiece can begin the processing to workpiece afterwards being pressed on the clamping platform under the atmospheric effect and being positioned at this moment.
