[0002] At present, the electric hammer cylinder is an important component of the electric hammer. It is usually a cylindrical cavity. Through the reciprocating motion of the piston in the cylinder, electrical energy or other forms of energy are converted into mechanical energy, thereby realizing the impact function of the electric hammer. The inner wall burr removal equipment for electric hammer cylinder processing is usually a tool specially designed to remove the burrs generated on the inner wall of the electric hammer cylinder during the processing process.

After the inner slider and the friction pad slide slightly with the cylinder body, the limiting rod and the elastic ring slide under the restriction of the inclined groove, thereby increasing the inward clamping force and limiting the sliding of the cylinder body, thereby avoiding that during the grinding and cleaning process, there is only the clamping force to limit the position of the cylinder body, but no friction to limit the rotation of the cylinder body, which causes the cylinder body to rotate during work, affects the burr cleaning and easily causes scratches on the surface of the cylinder body, and a limiting block is fixedly installed on the outside of the arc clamp frame, and the limiting block is symmetrically installed along the center position of the axis of the arc clamp frame, and the inner wall of the limiting block is slidably installed with an arc groove plate, and the end of the arc groove plate away from the limiting block is fixedly connected to the outside of the pneumatic chuck.

[0011] Preferably, the pneumatic chuck comprises a fixed plate, and the bottom of the fixed plate is fixedly connected to the top of the slot frame, and a slag collecting groove is provided at the center position of the top of the fixed plate, and a vertical plate is fixedly installed on the top of the fixed plate, and the vertical plate is evenly installed along the center position of the slag collecting groove, and a clamping hole is provided at the center position of the outer side of the vertical plate, and a clamping cylinder is fixedly installed at the clamping hole of the vertical plate, and the piston rod end of the clamping cylinder is fixedly connected to a connecting plate, and both sides of the connecting plate are fixedly connected to one end of the arc slot plate away from the limiting block, An arc groove block is fixedly connected to one end of the connecting plate away from the clamping cylinder.

In the process of the grinding head rotating to contact the inner wall of the cylinder body, it can be ensured that when the downward speed is too fast, the reaction force of the inner wall of the cylinder body on the grinding block can be buffered to avoid damage to the cylinder body, and the bottom of one of the clamping rings fits with the top of the connecting shaft.

[0014] The present invention provides a cylinder inner wall burr cleaning device for electric hammer cylinder processing. It has the following beneficial effects:

[0015] 1. The burr removal device for the inner wall of the cylinder used for electric hammer cylinder processing uses the inclined groove of the arc clamp frame and the characteristic that the farther the inclined groove is from the inner slider, the closer it is to the inside. During the process of grinding the inner wall of the cylinder to remove burrs, the cylinder is subjected to rotational force. At this time, through the friction between the friction pad and the cylinder, when the cylinder rotates slightly, through the inclined groove on the outside of the arc clamp frame, after the inner slider and the friction pad slide slightly with the cylinder, the limiting rod and the elastic ring slide under the restriction of the inclined groove, thereby increasing the inward clamping force and limiting the sliding of the cylinder, so as to avoid that during the grinding and cleaning process, there is only the clamping force to limit the position of the cylinder, but no friction to limit the rotation of the cylinder, which causes the cylinder to rotate during work, affects the burr cleaning and easily causes scratches on the surface of the cylinder.

[0016] 2. The burr removal equipment for the inner wall of the cylinder body used for electric hammer cylinder processing drives the clamping parts to clamp the cylinder body through the arc groove blocks symmetrically installed on the connecting plate, so that the cylinder body is clamped by the same force on the outside and is located in the center position, and the upper and lower sides are clamped at the same time, which can avoid the cylinder body tilting caused by the grinding head moving up and down during the grinding and cleaning of burrs.

[0017] 3. The burr cleaning equipment for the inner wall of the cylinder body used for electric hammer cylinder processing uses the elastic deformation characteristics of the gasket ring to make the inner clamp block and the side clamp block cooperate better. The rebound force generated by the gasket ring deforms the rubber pad on the outside of the inner clamp block to cooperate with the anti-slip mechanism to limit the rotation of the cylinder body. At the same time, the side clamp blocks on both sides cooperate with the inner clamp block to contact the cylinder body through three points, so as to better contact the outside of the cylinder body for clamping.

[0018] 4. The burr cleaning equipment for the inner wall of the cylinder used for electric hammer cylinder processing increases the buffer distance while ensuring that the deformation pressure remains unchanged through the oppositely installed elastic gaskets. When the grinding head rotates and contacts the inner wall of the cylinder, it can ensure that when the downward speed is too fast, the reaction force of the inner wall of the cylinder on the grinding block can be buffered to avoid damage to the cylinder.

[0031] The frame body is composed of a base 4, a slot frame 5 and a cross beam 7 and has a frame supporting the structural components.

Cylinders 8 are fixedly installed on both sides of the slot frame 5, and the piston rod ends of the cylinders 8 are fixedly connected to both sides of the bottom of the cross beam 7;

[0032] A pneumatic chuck 1, which is used to clamp the cylinder body, and the pneumatic chuck 1 is fixedly installed on the top of the slot frame 5;

[0033] An anti-skid mechanism 3, which is used to assist the pneumatic chuck 1 in limiting the rotation of the cylinder body during the cylinder body burr cleaning process, and the anti-skid mechanism 3 is fixedly installed on the outer side of the pneumatic chuck 1;

[0034] The motor 6 is fixedly mounted at the center of the top of the crossbeam 7, and the output end of the motor 6 passes through the crossbeam 7 and extends to the bottom thereof;

[0035] A grinding head 2, which is used to clean the burrs on the inner wall of the cylinder body under the drive of the motor 6, and the top end of the grinding head 2 is connected to the output end of the motor 6;

[0036] The anti-slip mechanism 3 includes an arc clamp frame 31, and the upper and lower sides of the arc clamp frame 31 are provided with oblique grooves, the oblique grooves are located on one side of the outer side of the arc clamp frame 31, and a limiting rod 36 is slidably installed in the oblique groove of the arc clamp frame 31, and an elastic ring 37 is fixedly installed at the oblique groove of the arc clamp frame 31, and an inner sliding block 35 is fixedly installed at the center position of the outer side of the limiting rod 36, and the inner sliding block 35 is located on the side of the inner wall of the arc clamp frame 31 away from the oblique groove, and the outer side of the inner sliding block 35 is slidably adapted to the inner wall of the arc clamp frame 31, and in the process of the connecting plate 106 moving toward the center position, the arc groove plate 33 is driven to move toward the center position, so that the position between the limiting block 32 and the arc groove plate 33 changes, and the arc clamp frame 31 is driven to move toward the center position. In the process of approaching the center position, the friction pad 34 contacts the outer side of the cylinder body and cooperates with the rubber pad 110 to clamp the cylinder body, and the outer side of the inner sliding block 35 is fixedly installed with a friction pad The pad 34 is made of rubber material and has friction patterns on its surface. The farther the inclined groove of the arc clamp frame 31 is from the inner slider 35, the closer it is to the inside. A limiting block 32 is fixedly installed on the outer side of the arc clamp frame 31, and the limiting block 32 is symmetrically installed along the center position of the axis of the arc clamp frame 31. When grinding and cleaning the burrs on the inner wall of the cylinder body, the cylinder body is subjected to rotational force due to the friction between the burrs and the grinding head 2. At this time, through the friction between the friction pad 34 and the cylinder body, when the cylinder body rotates slightly, through the inclined groove on the outer side of the arc clamp frame 31, after the inner slider 35 and the friction pad 34 slide slightly with the cylinder body, the limiting rod 36 and the elastic ring 37 slide under the restriction of the inclined groove, thereby increasing the inward clamping force and limiting the sliding of the cylinder body. The inner wall of the limiting block 32 is slidably installed with an arc groove plate 33, and the end of the arc groove plate 33 away from the limiting block 32 is fixedly connected to the outer side of the pneumatic chuck 1.

[0037] The second embodiment is based on the first embodiment. Figures 5 and 6As shown, the pneumatic chuck 1 includes a fixed plate 101, and the bottom of the fixed plate 101 is fixedly connected to the top of the slot frame 5, and a slag collecting groove 103 is provided at the center position of the top of the fixed plate 101, and a vertical plate 102 is fixedly installed on the top of the fixed plate 101, and the vertical plates 102 are evenly installed along the center position of the circle of the slag collecting groove 103, and the center position of the outer side of the vertical plate 102 is provided with a clamping hole, and the clamping hole of the vertical plate 102 is fixedly installed, and the piston rod end of the clamping cylinder 104 is fixedly connected with a connecting plate 106, and the two sides of the connecting plate 106 are fixedly connected to the end of the arc slot plate 33 away from the limiting block 32, and the connecting plate 106 is driven to approach the center position by the clamping cylinder 104. In the process of approaching, the connecting plate 106 is driven to approach the center position by the connecting plate 104. The connecting plate 106 drives the arc groove block 105 to approach the outside of the cylinder body. During the approach process, the inner clamping block 109 at the center position of the arc surface of the arc groove block 105 first contacts the outside of the cylinder body. At the same time, during the process of the inner clamping block 109 contacting the outside of the cylinder body, it first contacts the cylinder body through the clamped rubber pad 110. In the process of the clamping cylinder 104 constantly approaching the center position, the contact pressure between the inner clamping block 109 and the cylinder body gradually increases. The arc groove block 105 is fixedly connected to one end of the connecting plate 106 away from the clamping cylinder 104. The arc groove block 105 is symmetrically installed along the center position of the axis of the connecting plate 106, and an adjustment groove is opened at the center position of the outer side of the arc groove block 105, and a gasket ring 107 is fixedly installed in the adjustment groove of the arc groove block 105.

[0038] The side of the arc groove block 105 away from the connecting plate 106 is an arc surface, and both ends of the arc surface of the arc groove block 105 are fixedly connected with side clamping blocks 108. The inner wall of the arc groove block 105 is slidably installed with an inner clamping block 109. The inner clamping block 109 contacts the gasket 107. The gasket 107 is made of elastic material. The inner clamping block 109 is located at the center of the arc surface of the arc groove block 105. In the process of increasing pressure, the pressure is transmitted to the gasket 107, so that the gasket 107 is elastically deformed under pressure, and the inner clamping block 109 begins to slide, so that the side clamping blocks 108 on both sides can contact the outside of the cylinder body, and cooperate with the inner clamping block 109 to clamp the outside of the cylinder body. At the same time, in the process of cleaning burrs, the rubber pad 110 deformed under the clamping pressure cooperates with the anti-slip mechanism 3 to limit the rotation of the cylinder body, and a card groove is opened at the center of the outer side of the inner clamping block 109, and the rubber pad 110 is clamped at the card groove of the inner clamping block 109.

[0039] The third embodiment is based on the first and second embodiments. Figures 7 to 9As shown, the grinding head 2 includes a transmission shaft 21, a coupling 25 is installed at the top of the transmission shaft 21, and the top of the transmission shaft 21 is connected to the output end of the motor 6 through the coupling 25, and the bottom end flange of the transmission shaft 21 is connected to the connecting shaft 27, and the bottom of the outer side of the connecting shaft 27 is slidably installed with a sleeve 22. The output end of the motor 6 is connected to the transmission shaft 21 through the coupling 25, driving the transmission shaft 21 to rotate, so that the transmission shaft 21 drives the connecting shaft 27 to rotate, and the connecting shaft 27 drives the sleeve 22 to rotate. During the rotation of the sleeve 22, the grinding block 23 fixed by the groove rotates along the axis of the transmission shaft 21, and the burrs are cleaned after the grinding block 23 contacts the inner wall of the cylinder body. The outer side of the sleeve 22 is evenly provided with grooves, and the outer side of the sleeve 22 is fixedly connected with the grinding block 23 through the groove. A clamping ring 26 is installed at the top of the outer side of the shaft 27. There are two clamping rings 26, and elastic gaskets 24 are installed between the clamping rings 26. The crossbeam 7 is driven downward by the cylinder 8, so that the motor 6 and the grinding head 2 are moved downward as a whole, and cleaning is performed from top to bottom along the inner wall of the cylinder body. At the same time, during the cleaning process, the inner wall of the cylinder body generates an upward limiting force on the downward movement of the grinding block 23, so that the limiting force is transmitted to the clamping ring 26 through the grinding block 23 and the shaft sleeve 22, so that the clamping ring 26 transmits the pressure to the elastic gasket 24, and the limiting force is buffered by the deformation of the elastic gasket 24. At the same time, the relatively arranged elastic gaskets 24 increase the buffering distance without changing the deformation force. There are two elastic gaskets 24 and they are installed oppositely, and the bottom of one of the clamping rings 26 is in contact with the top of the connecting shaft 27.

[0040] During use, the worker places the electric hammer cylinder body to be processed into the center position of the pneumatic chuck 1, and clamps the cylinder body by starting the pneumatic chuck 1. At the same time, during the clamping process, the anti-slip mechanism 3 is driven to clamp the cylinder body. Then the worker starts the motor 6, so that the motor 6 drives the grinding head 2 to rotate, and drives the crossbeam 7 downward through the cylinder 8, so that the crossbeam 7, the motor 6 and the grinding head 2 move downward together to grind the burrs on the inner wall of the cylinder body.

[0041] In the process of clamping the cylinder body by the pneumatic chuck 1, the connecting plate 106 is driven to approach the center position by the clamping cylinder 104. In the process of approaching, the arc groove block 105 is driven to approach the outside of the cylinder body by the connecting plate 106. In the process of approaching, the inner clamping block 109 at the center position of the arc surface of the arc groove block 105 first contacts the outside of the cylinder body. At the same time, in the process of the inner clamping block 109 contacting the outside of the cylinder body, it first contacts the cylinder body through the clamped rubber pad 110. In the process of the clamping cylinder 104 constantly approaching the center position, the contact pressure between the inner clamping block 109 and the cylinder body gradually increases. In the process of increasing pressure, the pressure is transmitted to the gasket 107, so that the gasket 107 is elastically deformed under pressure, and the inner clamping block 109 starts to slide, so that the side clamping blocks 108 on both sides can contact the outside of the cylinder body, and cooperate with the inner clamping block 109 to clamp the outside of the cylinder body. At the same time, in the process of cleaning burrs, the rubber pad 110 deformed under the clamping pressure cooperates with the anti-slip mechanism 3 to limit the rotation of the cylinder body.

[0042] In the process of connecting plate 106 moving toward the center position, arc groove plate 33 is driven to move toward the center position, so that the position between limiting block 32 and arc groove plate 33 changes, and arc clamp frame 31 is driven to move toward the center position. In the process of approaching the center position, friction pad 34 contacts the outside of cylinder body and cooperates with rubber pad 110 to clamp the cylinder body. When grinding and cleaning the burrs on the inner wall of cylinder body, the friction between burrs and grinding head 2 causes the cylinder body to be subjected to rotational force. At this time, through the friction between friction pad 34 and cylinder body, when the cylinder body rotates slightly, through the oblique groove on the outside of arc clamp frame 31, after the inner slider 35 and friction pad 34 slide slightly with the cylinder body, the limiting rod 36 and elastic ring 37 slide under the restriction of the oblique groove, thereby increasing the inward clamping force and limiting the sliding of the cylinder body.

[0043] When cleaning burrs through the grinding head 2, the output end of the motor 6 is connected to the transmission shaft 21 through the coupling 25, driving the transmission shaft 21 to rotate, so that the transmission shaft 21 drives the connecting shaft 27 to rotate, and the connecting shaft 27 drives the sleeve 22 to rotate. During the rotation of the sleeve 22, the grinding block 23 fixed by the slot rotates along the axis of the transmission shaft 21. After the grinding block 23 contacts the inner wall of the cylinder, the burrs are cleaned, and the crossbeam 7 is driven downward by the cylinder 8, so that the motor 6 and the grinding head 2 move downward as a whole, and clean from top to bottom along the inner wall of the cylinder. At the same time, during the cleaning process, the inner wall of the cylinder generates an upward limiting force on the downward movement of the grinding block 23, so that the limiting force is transmitted to the clamping ring 26 through the grinding block 23 and the sleeve 22, so that the clamping ring 26 transmits the pressure to the elastic gasket 24, and the limiting force is buffered by the deformation of the elastic gasket 24. At the same time, the relatively arranged elastic gasket 24 increases the buffering distance without changing the deformation force.
