Abstract
The invention discloses an abrasive belt polishing machine with a constant-pressure device, which comprises a machine base, a connecting plate arranged on the machine base in a way of being capable of moving front and back and a polishing wheel arranged in front of the connecting plate through a connecting mechanism, wherein the polishing wheel is connected with an abrasive belt; the machine base is connected with a rotatable air cylinder; the free end of a piston rod is connected with the connecting plate through a lever; one end of the lever is hinged with the piston rod, and the other end of the lever is connected with the connecting plate in a rotatable and slidable manner; and the fulcrum of the lever is fixedly connected with the machine base. Through the arrangement of the air cylinder and the lever, the constant-pressure action on a workpiece to be machined can be realized. When the raised part of the workpiece to be machined is pressed against the abrasive belt, namely the pressure applied by the workpiece to be machined on the abrasive belt is higher, the polishing wheel drives the abrasive belt to withdraw, so the condition that the workpiece to be machined is pressed against the abrasive belt too tightly can be prevented effectively. Thus, the service life of the abrasive belt can be prolonged effectively and the rejection rate is reduced.

The specific embodiment
The specific embodiment of the present invention is described with reference to the accompanying drawings.
With reference to Fig. 1 and Fig. 4; A kind of belt sander with constant-voltage equipment comprises that top has the support 1 of side plate 11, and a side of side plate 11 is provided with a plate 2; Connecting plate 2 roughly is the rectangle that is reamed an angle, and connecting plate 2 can forward and backward slippage on support 1.Offer plurality of windows 111 on the side plate 11, and another side of side plate 11 is provided with cylinder 3 (this cylinder 3 is for making the constant voltage cylinder that keeps constant air pressure in the cylinder body).The cylinder body 31 of cylinder 3 articulates with the connecting rod that is fixedly arranged on support 1 33, and cylinder 3 can rotate up and down around the pivot end with connecting rod 33.The free end of cylinder 3 piston rods 32 and an end of lever 4 are hinged, and the other end of lever 4 passes window 111 and is connected in connecting plate 2.Refer again to Fig. 4; Be fixedly connected with the circle wheel 22 that has rotating shaft 21 on the connecting plate 2, the end that lever 4 is connected with connecting plate 2 is provided with the breach 41 of U-shaped, and said rotating shaft 21 is positioned at breach 41; Through above-mentioned setting, can guarantee a end that lever 4 is connected with connecting plate 2 rotatable and can before and after slide.Lever 4 is provided with the rotation seat 5 that can play point action, and lever 4 can rotate around rotation seat 5 during use, and rotation seat 5 is fixedly connected on the side plate 11 of support 1, and when rotation seat 5 during near an end of hinged place, effect is preferable.
Refer again to Fig. 1 and Fig. 4; Connecting plate 2 is fixedly connected with an end of upper and lower two connecting rods 6; The other end of connecting rod 6 protrudes from the front end of connecting plate 2, and be connected with polishing wheel 71 respectively on the other end, following polishing wheel 72, the diameter of last polishing wheel 71 is bigger than the diameter of following polishing wheel 72.Last polishing wheel 71, the middle part of polishing wheel 72 is provided with axis hole (not drawing among the figure) down, and the compartment of terrain is provided with the locating hole 61 that matches with axis hole on the connecting rod 6, and last polishing wheel 71, time polishing wheel 72 can be fixedly connected on upper and lower connecting rod 6 through locating hole 61.Through locating hole 61 is set on connecting rod 6, can regulates the distance between polishing wheel 71 or following polishing wheel 72 and the connecting plate 2 easily, thereby help processing more to be processed of difference.In addition, upper and lower polishing wheel 71,72 can be followed connecting plate 2 easily, the reach operation; After move standby, thereby can save the energy.
Simultaneously with reference to Fig. 2, last polishing wheel 71, polishing wheel 72 is through abrasive band 73 connections down, and abrasive band 73 runs up and processes to machined part.Also be provided with upper and lower two dampings 8 on the support 1, damping 8 and cylinder 3 are positioned at the same side of side plate 11, and damping 8 is connected in connecting plate 2 through window 111.With reference to Fig. 3, damping 8 comprises axostylus axostyle 81 that is fixedly connected on support 1 and the housing 82 that is sheathed on axostylus axostyle 81 simultaneously, connects through linear bearing 83 between housing 82 and the axostylus axostyle 81, and housing 82 can be free to slide on axostylus axostyle 81.Housing 82 is fixedly connected on connecting plate 2, and the two ends of housing 82 are tightly connected through extension airbag 9 and support 1 respectively.
Hold by manipulator for to be processed, and processing on the abrasive band that runs up 73.Lever 4 receives to be processed pressure with the link of connecting plate 2; The link of lever 4 and piston rod 32 receives the pressure of cylinder 3.When to be processed lug boss and abrasive band 73 butts; Abrasive band 73 just can receive bigger pressure; This moment, moved together with connecting plate 2 backward in abrasive band 73; The link of lever 4 and connecting plate 2 is also along with connecting plate 2 moves backward, and lever 4 then travels forward with the link of piston rod 32, and promptly piston rod 32 is compressed.Cylinder 3 adopts the constant voltage cylinder; And the air pressure in the constant voltage cylinder body can remain on a steady state value; Therefore lever 4 can keep above-mentioned state always; Lug boss to machined part adds man-hour, and connecting plate 2 is in the state that backward moves all the time, thereby has prevented that effectively to be processed is pushed up to such an extent that the situation of tension takes place with abrasive band 73.When to be processed not lug boss of processing, the pressure that abrasive band 73 receives reduces, and piston rod 32 stretches, and abrasive band 73 was communicated with connecting plates 2 and travelled forward under the effect of lever 4 this moment.
Above-mentionedly be merely the specific embodiment of the present invention, but design concept of the present invention is not limited thereto, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should belong to the behavior of invading protection domain of the present invention.
