Abstract
The utility model exhaust valve seat clamp system, comprises holder, and described holder is provided with upper and lower two connecting plates, and the side of described two connecting plates is connected and fixed by gripper shoe; Described connecting plate offers holes for clamping, is provided with wedge in described holes for clamping, the one side that described wedge is relative with gripper shoe is parallel with gripper shoe; Described upper junction plate is provided with a fixed block, and described fixed block is provided with vertical chute, is fixed with a thread bush in described chute, and the top of described wedge is rotatably connected to a screw rod, and described screw rod coordinates with thread bush.Can be clamped workpiece by wedge.By rotating screw bolt, mobile wedge, under the effect on inclined-plane, wedge slowly clamps workpiece.Because the bonded area of wedge and workpiece is large, and the process control of clamping, clamping force increases gradually, and therefore, workpiece can not be clamped power damaged deformation.Be threaded and can make wedge self-locking man-hour adding, prevent wedge motion in processing, play fixing effect.
Description
Technical field
The utility model relates to a kind of clamp system, is specifically related to a kind of exhaust valve seat clamp system.
Background technology
Cylinder cap is arranged on above cylinder body, forms combustion chamber from top seal cylinder.It often contacts with high-temperature high-pressure fuel gas, therefore bears very large thermic load and mechanical load.The cylinder head inside of water-cooled engine is shaped with cooling jacket, and the cooling water hole of cylinder cap lower surface communicates with the cooling water hole of cylinder body.Recirculated water is utilized to carry out the high-temperature part such as cooling combustion room.Cylinder cap being also equipped with Valve seat, valve guide hole, for being installed into, exhaust valve, also having inlet channel and exhaust passage etc.The cylinder head of gasoline engine is processed with the hole of installing spark plug, and the cylinder head of diesel engine is processed with the hole of installing fuel injector.The cylinder head of cammer is also processed with cam shaft bearing bore, in order to install camshaft.The exhaust valve seat thermal conductivity of aluminium alloy is good, is conducive to the reduced overall ratio improving cylinder.But the hardness of aluminium alloy is lower, and work in-process very easily deforms.To cause in the factor of distortion be on the one hand fixture itself cause workpiece local clamping force excessive deformation, be the distortion that in processing, process tool causes on the other hand.
Utility model content
The purpose of this utility model is to provide a kind of exhaust valve seat clamp system, by structural design optimization workpiece stressed improved, prevents the pinching deformation of workpiece.
For achieving the above object, the technical solution of the utility model is: exhaust valve seat clamp system, comprises holder, and described holder is provided with upper and lower two connecting plates, and the side of described two connecting plates is connected and fixed by gripper shoe; Described connecting plate offers holes for clamping, is provided with wedge in described holes for clamping, the one side that described wedge is relative with gripper shoe is parallel with gripper shoe; Described upper junction plate is provided with a fixed block, and described fixed block is provided with vertical chute, is fixed with a thread bush in described chute, and the top of described wedge is rotatably connected to a screw rod, and described screw rod coordinates with thread bush.
When adopting technique scheme, can be clamped workpiece by wedge.By rotating screw bolt, mobile wedge, under the effect on inclined-plane, wedge slowly clamps workpiece.Because the bonded area of wedge and workpiece is large, and the process control of clamping, clamping force increases gradually, and therefore, workpiece can not be clamped power damaged deformation.In addition, the connected mode of screw thread, can make wedge self-locking man-hour adding, and prevents wedge motion in processing, plays fixing effect.
Further, the bevel angle of described wedge is 6 °.
Further, described fixed block is locked by two studs.
Further, described screw rod is provided with stage clip between thread bush and wedge.This setting can in use have a precompose firmly to wedge.
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 utility model exhaust valve seat clamp system embodiment.
Detailed description of the invention
As shown in Figure 1, the utility model exhaust valve seat clamp system, comprises holder, and the side that holder is provided with upper and lower two connecting plates 1, two connecting plates 1 is connected and fixed by gripper shoe 2; Connecting plate 1 offers holes for clamping, is provided with wedge 3 in holes for clamping, the bevel angle of wedge is 6 °.The one side that wedge 3 is relative with gripper shoe 2 is parallel with gripper shoe 2.The holes for clamping of upper junction plate is greater than the supported hole of lower clamping plate, and the left end of supported hole is plane, and right-hand member is inclined-plane.Upper junction plate is provided with a fixed block 4, and fixed block 4 is locked by two studs 5.Fixed block 4 is provided with vertical chute, is fixed with a thread bush in chute, is rotatably connected to a screw rod 42 on the top of wedge 3, and this screw rod 42 coordinates with thread bush.Screw rod 42 is provided with stage clip 6 between thread bush and wedge 3.This setting can in use have a precompose firmly to wedge 3.
The utility model gathers, and can be clamped by wedge 3 to workpiece 7.By rotating screw bolt 42, drive wedge 3 to move, under the effect on inclined-plane, wedge 3 pairs of workpiece 7 slowly clamp.Because wedge 3 is large with the bonded area of workpiece 7, and the process control of clamping, clamping force increases gradually, and therefore, workpiece 7 can not be clamped power damaged deformation.In addition, the connected mode of screw thread, can make wedge 3 self-locking man-hour adding, and prevents wedge 3 in processing from moving, plays fixing effect.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; without departing from the concept of the premise utility; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
