Description
Technical field
The utility model relates to thermostat manufacture field, specifically a kind of frock clamp of thermostat valve seat.
Background technology
Thermostat is the valve of controlling coolant flow paths.Be a kind of automatic temperature-regulator, conventionally contain the temperature module, open and close flowing of air, gas or liquid by expansion or shrinkage.And the valve seat of described thermostat is often assembled by the valve seat laminating of two of left and right, in this course in order to ensure the sealing of thermostat inner chamber, the relative binding face of left and right valve seat just needs higher flatness, and expansion or shrinkage that the working environment of described thermostat is often accompanied by frequent replacement change, and therefore ensure that the flatness of the binding face on this valve seat just seems particularly important.
In prior art, the multiple tracks surface treatment such as milling, the polishing grinding of grinding machine through face miller reaches the technical requirement for the end face flatness of thermostat valve seat often, and in this course, how accurate clamping is located this thermostat valve seat just becomes a great problem in industry.First, the outer surface of thermostat valve seat is irregular globoidal structure, therefore the effectively clamping and positioning of fixture clamping by common left and right, secondly, what in prior art, this thermostat valve seat was more is to form by die casting, therefore the dimensional accuracy of its outer surface is often poor, can cause the mismachining tolerance of to be processed of thermostat valve seat to become large during thus using outer surface poor precision as clamping and positioning point, affects Surface Machining precision.
Summary of the invention
Technical problem to be solved by this invention is: a kind of frock clamp that can fix to clamp thermostat valve seat and make to be processed good processing accuracy of thermostat valve seat is provided.
The technical solution used in the present invention is: the frock clamp that a kind of thermostat valve seat is provided, it comprises base plate, base plate is provided with for support product and pillar that the upper surface of product is the level of state, support bar, the first push rod and the second push rod, and the sidewall of one end and product leans for the backstay of spacing product along continuous straight runs motion, it also comprises the compact heap of being located on base plate in the second through hole arranging in horizontal direction for stretching into product and compressing the inwall of the second through hole towards vertical direction downwards, one end of stretching in the second through hole of compact heap is provided with the flange extending towards the outside that deviates from position, compact heap axis, the cross sectional shape that described flange is vertically gone up matches with the cross sectional shape of the second through hole of product, the below of one end away from product of described compact heap is provided with support column, the lower end of support column and the upper surface of base plate in described compact heap stretches into the second through hole of product and described in while compressing the inwall of the second through hole lean, described compact heap is provided with the through hole of strip, described base plate be provided with one with compact heap on the guide post that is slidably matched of the through hole of strip, the lower end of guide post is fixedly connected with base plate, its upper end extends to the top of compact heap and the through hole of break-through strip, the upper end of described guide post is provided with external screw thread, described guide post is provided with and coordinates with the external screw thread of guide post for ordering about the descending locking nut of compact heap, on described guide post, cover has a spring, the lower end of described spring is fixedly connected with base plate, the upper end of spring and the lower surface of compact heap lean,
The upper end of described pillar is provided with the projection matching with the first through hole on product, it is up big and down small inflation port that described projection is provided with aperture, and in inflation port, be provided with the jacking block matching in the longitudinal section of a vertical direction and the longitudinal section of inflation port, the diameter of the lower surface of jacking block is less than the aperture of the upper surface of inflation port, and the diameter of the lower surface of jacking block is greater than the aperture of the lower surface of inflation port, described jacking block is fixedly connected with underrun one adjusting bolt of inflation port.
Its operation principle is in simple terms: first, the first through hole of product is placed on outside the projection on pillar, and make each location point and the support bar on product, the upper surface of the first push rod and the second push rod against, thereby ensure that product is the level of state, rotate subsequently product and make a bit the leaning with backstay of lateral wall of product, complete thus the location of the position of product, then, tighten by the hexagon socket head cap screw on projection, the inwall in trend compact heap extrusion expansion hole, make thus the madial wall of the lateral wall of inflation port and the first through hole of product fastening, finally, promote compact heap, one end of compact heap is extend in product, and screw locking nut, thereby trend compact heap overcomes the elastic force of spring makes the flange of one end of stretching into product of compact heap and the laminating of the inwall lower end of the second through hole of product and tight fit.
Adopt after above structure, the frock clamp of thermostat valve seat of the present invention compared with prior art has the following advantages: first, product is in installation process, its outer surface is not subject to very large clamping force, therefore product is difficult for because the clamping force of fixture causes distortion, secondly, support bar, pillar, the position of the strong point of the first push rod and the second push rod all can be adjusted according to different product, even if the strong point can be located at the good position of dimensional accuracy on product, therefore make the mismachining tolerance of the product that in product processing, the error due to clamping precision causes drop to minimum, finally, compress product by the inwall in the second through hole, compress effective, thereby and the precision of the higher upper surface that makes the product processing of precision in through hole is also higher.
As preferably, on described base plate, be also provided with a cushion block for support product lower surface, the lower surface of described cushion block and the upper surface of base plate are slidably matched, and cushion block is provided with the strip through hole of upper and lower break-through, the length direction of strip through hole is parallel with the length direction of cushion block, base plate is provided with two caging bolts that cushion block is slided along the length direction of strip through hole, and the extended line of the intersection point line of the axis of two caging bolts and base plate place horizontal plane is positioned at the lower end of product, the thickness of the vertical direction of one end of the close product of described cushion block is less than the thickness in the centre position of cushion block, and one end of the close product of cushion block is connected by chamfered transition with centre position.
As preferably, on the inwall of inflation port, along some grooves that are circumferentially with of self axis, whole grooves runs through the upper surface of projection vertically, and radially runs through the lateral wall of projection simultaneously.By groove is set, be divided into some annular slice structures by projection, thus with the distortion towards outside that is conducive to projection.
