Description

Technical Field

[0001] This application relates to the technical field of part processing, and in particular to a pushing mechanism. Background Art

[0002] When processing parts, the workbench surface for processing parts has side walls. Therefore, when fixing parts, only a pushing mechanism and the side walls are needed to fix the parts between the pushing mechanism and the side walls, and then the parts to be processed can be cut and processed.

[0003] Generally, a linear cylinder is directly used to fix the parts to be processed. The entire length of the cylinder is in the radial direction of the workbench surface, so the requirement for the radial dimension of the workbench surface is relatively large. In addition, the accuracy of the linear cylinder itself is relatively low, and it is easily affected by air pressure when fixing workpieces, resulting in unstable fixing. Summary of the Utility Model

[0004] This application provides a pushing mechanism, aiming to solve the above technical problems existing in the prior art.

The dimension of the first limiting groove in the first direction is greater than the dimension of the pushing block in the first direction, so that there is a gap between the side wall of the first limiting groove and the pushing block. During the movement of the wedge block in the first direction, the first inclined surface abuts against the abutting arc surface to make the pushing block move in the second direction, and the end of the pushing block away from the abutting arc surface can cooperate with the abutted part to make the pushing block deflect in the gap.

[0007] In some embodiments, the pushing mechanism includes a base, a pushing block is disposed on the base, the first limiting groove includes a first groove section and a second groove section that are in communication with each other.

The first part is disposed in the first groove section, the second part is disposed in the second groove section, and the size of the first part in the first direction is greater than the size of the second groove section in the first direction.

[0008] In some embodiments, the pushing mechanism further includes a baffle and an elastic member. The baffle is located at one end of the base away from the wedge block. The baffle is connected to the base. The elastic member is elastically supported between the pushing block and the baffle.

[0009] In some embodiments, the elastic member includes a spring. The pushing block has a compression groove. The elastic member is at least partially located in the compression groove. The elastic member is elastically supported between the baffle and the bottom wall of the compression groove.

[0010] In some embodiments, the base includes a second limiting block. The second limiting block and the first limiting block are spaced apart in the second direction to form a second limiting groove extending in the first direction. The wedge block moves in the second limiting groove.

[0011] In some embodiments, the pushing mechanism includes a driving cylinder. The driving cylinder is connected to the wedge block. The driving cylinder is used to drive the wedge block to move in the first direction. The driving cylinder is fixed to the first limiting block and the second limiting block.

[0012] In some embodiments, the pushing mechanism further includes a side pushing block. The side pushing block is connected to one end of the pushing block away from the wedge block. The side pushing block extends in the second direction. The pushing block abuts against the abutted member through the side pushing block.

[0013] In some embodiments, the side pushing block includes a first side top portion and a second side top portion that are connected to each other. The first side top portion and the second side top portion both extend in the first direction. The first side top portion protrudes from the second side top portion in the direction away from the first limiting block in the second direction.

[0014] In some embodiments, one side of the first side top portion away from the first limiting block is serrated and extends in the first direction.

The size of the first limiting groove in the first direction is larger than the size of the pushing block in the first direction, so that there is a gap between the side wall of the first limiting groove and the pushing block. During the process of the wedge block moving in the first direction, the first inclined surface contacts the contact arc surface to make the pushing block move in the second direction, and one end of the pushing block away from the contact arc surface can cooperate with the contacted part to make the pushing block deflect in the gap. Through the above implementation manner, during the process of the wedge block moving in the first direction, by contacting the contact arc surface, the pushing block is pushed to move in the second direction, and the pushing block deflects in the first limiting groove with the contact arc surface as the fulcrum, thereby increasing the contact surface with the contacted part, so that the accuracy of fixing the contacted part is higher and the fixing is more stable.

[0033] To solve the technical problems existing in the related art, the present application provides a pushing mechanism. Refer to Figure 1 and Figure 2 , Figure 1 is the first perspective view of an embodiment of the pushing mechanism provided by the present application. Figure 2 is Figure 1 the enlarged structural schematic diagram of the pushing mechanism shown.

[0034] The pushing mechanism 10 includes a wedge block 110, a first limiting block 120, and a pushing block 130. The wedge block 110 includes a first inclined surface 111, and the wedge block 110 is configured to move in the first direction X; the first limiting block 120 is formed with a first limiting groove 121 extending along the second direction Y, and the first direction X and the second direction Y intersect; the pushing block 130 is located in the first limiting groove 121, and one end of the pushing block 130 facing the wedge block 110 has an abutting arc surface 131, and the abutting arc surface 131 is configured to abut against the first inclined surface 111. The dimension of the first limiting groove 121 in the first direction X is greater than the dimension of the pushing block 130 in the first direction X, so that there is a gap between the side wall of the first limiting groove 121 and the pushing block 130. During the movement of the wedge block 110 along the first direction X, the first inclined surface 111 abuts against the abutting arc surface 131 to cause the pushing block 130 to move along the second direction Y, and one end of the pushing block 130 away from the abutting arc surface 131 can cooperate with the abutted member 20 to cause the pushing block 130 to deflect in the gap.

[0035] The wedge block 110 includes a first inclined surface 111, and the surface opposite to the first inclined surface 111 may be parallel to the first direction X. The wedge block 110 may further include a bottom surface, and the bottom surface may be perpendicular to both the first inclined surface 111 and the surface opposite to the first inclined surface 111, which helps the wedge block 110 to move in the first direction X.

[0036] The first limiting block 120 is formed with a first limiting groove 121 extending along the second direction Y, and the side wall of the first limiting groove 121 may be parallel to the second direction Y. The first limiting groove 121 may belong to one first limiting block 120, or the first limiting groove 121 may belong to two first limiting blocks 120. That is to say, a first limiting groove 121 may be cut out in one first limiting block 120; a groove may be dug out in each of the two first limiting blocks 120, and the two first limiting blocks 120 are arranged at intervals facing each other. Thus, the first limiting groove 121 may be jointly formed by the two grooves of the two first limiting blocks 120.

[0037] The pushing block 130 is located in the first limiting groove 121. The dimension of the pushing block 130 in the third direction Z perpendicular to the first direction X and the second direction Y matches the dimension of the first limiting groove 121 in the third direction Z. Thus, the first limiting block 120 can limit the pushing block 130 in the third direction Z. One end of the pushing block 130 abuts against the first inclined surface 111, and the plane where the other end is located can be parallel to the first direction X and can abut against the abutted member 20. The end abutting against the first inclined surface 111 is provided with an abutting arc surface 131. Therefore, when the wedge block 110 moves in the first direction X, the first inclined surface 111 can abut against the abutting arc surface 131 to make the wedge block 110 push the pushing block 130 to move in the second direction Y. In addition, the dimension between the two side walls of the first limiting groove 121 spaced in the first direction X is larger than the dimension of the pushing block 130 in the first direction X. Thus, there is a gap between the pushing block 130 and the first limiting groove 121. When the surface of the abutted member 20 in contact with the pushing block 130 is uneven or the contact surface between the pushing block 130 and the abutted member 20 is small, that is, when the pushing block 130 cannot fit with the abutted member 20, since there is a gap between the pushing block 130 and the first limiting block 120 in the first direction X, the pushing block 130 uses the abutting arc surface 131 as a fulcrum, so that the pushing block 130 can cooperate with the abutted member 20 to deflect in the gap, thereby increasing the contact area with the abutted member 20.

[0038] Through the above embodiments, during the process of the wedge block 110 moving in the first direction X, by abutting against the abutting arc surface 131, it pushes the pushing block 130 to move in the second direction Y. The pushing block 130 deflects in the first limiting groove 121 with the abutting arc surface 131 as a fulcrum, thereby increasing the contact surface with the abutted member 20. Thus, the accuracy of fixing the abutted member 20 is higher and the fixing is more firm.

[0039] In some embodiments, the pushing block 130 includes a second inclined surface 132. The second inclined surface 132 is connected to the abutting arc surface 131. The second inclined surface 132 and the first inclined surface 111 have the same inclination direction with respect to the second direction Y. The first inclined surface 111 and the second inclined surface 132 are at least partially spaced apart in the second direction Y. The abutting arc surface 131 can extend in the direction of the wedge block 110 in the second direction Y, and the extension lengths of the abutting arc surface 131 to both sides of the pushing block 130 can gradually decrease, thereby forming the second inclined surface 132. The inclination angle of the second inclined surface 132 is different from that of the first inclined surface 111, so that there is a gap between the first inclined surface 111 and the second inclined surface 132. Due to the existence of this gap, the abutting arc surface 131 can have a deflection space with respect to the first inclined surface 111. In some embodiments, there can be two second inclined surfaces 132. The two second inclined surfaces 132 are arranged oppositely. The two second inclined surfaces 132 are respectively connected to both sides of the abutting arc surface 131, and the difference in the orientations of the two second inclined surfaces 132 is about 90 degrees. That is to say, the abutting arc surface 131 extends outward with respect to the pushing block 130 in the second direction Y, and the extension distances of the abutting arc surface 131 to both sides of the pushing block 130 gradually decrease to form two second inclined surfaces 132. Thereby, the radius of curvature of the abutting arc surface 131 can be reduced, making the pushing block 130 more flexible when deflecting with the abutting arc surface 131 as the fulcrum.

[0040] See Figure 3 , Figure 3 is a second perspective view of an embodiment of the pushing mechanism provided by the present application.

[0041] In some embodiments, the pushing mechanism 10 includes a base 140. The pushing block 130 is disposed on the base 140. The first limiting groove 121 includes a first groove section 1211 and a second groove section 1212 that communicate with each other. Both the first groove section 1211 and the second groove section 1212 extend along the second direction Y. The dimension of the first groove section 1211 in the first direction X is larger than the dimension of the second groove section 1212 in the first direction X. The second groove section 1212 is farther from the base 140 than the first groove section 1211. The pushing block 130 includes a first part 133 and a second part 134 that are connected to each other. The dimension of the first part 133 in the first direction X is larger than the dimension of the second part 134 in the first direction X. The first part 133 is disposed in the first groove section 1211, and the second part 134 is disposed in the second groove section 1212. The dimension of the first part 133 in the first direction X is larger than the dimension of the second groove section 1212 in the first direction X.

[0042] The pushing block 130 and the first limiting block 120 are both arranged on the upper surface of the base 140. The first limiting groove 121 includes a first groove section 1211 and a second groove section 1212. The first groove section 1211 and the second groove section 1212 are arranged adjacent to each other. The side wall of the second groove section 1212 extends towards each other along the first direction X relative to the first groove section 1211, so that the dimension of the first groove section 1211 in the first direction X is larger than the dimension of the second groove section 1212 in the first direction X. The side of the first groove section 1211 away from the second groove section 1212 is fixed to the base 140. The pushing block 130 includes a first part 133 and a second part 134 which are connected to each other and arranged adjacent to each other. The dimension of the first part 133 in the first direction X is larger than the dimension of the second groove section 1212 in the first direction X. The first part 133 is located in the first groove section 1211. The dimension of the first part 133 in the first direction X is smaller than the dimension of the first groove section 1211 in the first direction X. The dimension of the second part 134 in the first direction X is smaller than the dimension of the second groove section 1212 in the first direction X. That is to say, there is a gap between the pushing block 130 and the first limiting groove 121 in the first direction X, and the gaps can be equal. In addition, the dimension of the first part 133 in the first direction X is larger than the dimension of the second groove section 1212 in the first direction X, so that the pushing block 130 can be restricted in the first limiting groove 121. The dimension of the first groove section 1211 in the third direction Z can match the dimension of the first part 133 in the third direction Z, so that the upper surface of the platform between the first part 133 and the second part 134 is slidably connected to the side wall between the first groove section 1211 and the second groove section 1212. Furthermore, the first limiting block 120 can limit the pushing block 130 in the third direction Z, and the pushing block 130 can fix the abutted member 20 at a fixed height, thereby improving the precision of the pushing mechanism 10.

[0043] In some embodiments, positioning holes and screw holes penetrating the upper surface may be provided at the corresponding positions of the base 140 and the first limiting block 120 in the third direction Z. The positioning holes are convenient for determining the dimension of the first limiting groove 121 in the first direction X. Screw holes penetrating the upper and lower surfaces may be provided on the first limiting block 120 in the third direction Z to fix the first limiting block 120 to the base 140 through screws. The base 140 is fixedly connected to the workbench surface. The base 140 may include fixing parts which may be located on both sides of the base 140 in the first direction X. The fixing parts have screw holes which cooperate with the screw holes of the workbench surface and screws to fix the base 140 on the workbench surface.

[0044] See Figure 4 , Figure 4 Yes Figure 1 The sectional view of the pushing mechanism shown along the A-A direction.

[0045] In some embodiments, the pushing mechanism 10 further includes a baffle 150 and an elastic member 160. The baffle 150 is located at one end of the base 140 away from the wedge 110. The baffle 150 is connected to the base 140. The elastic member 160 is elastically supported between the pushing block 130 and the baffle 150. When the wedge 110 pushes the pushing block 130 towards the abutted member 20, the elastic member 160 is in a compressed state between the baffle 150 and the pushing block 130. When the wedge 110 returns, the elastic member 160 can push the pushing block 130 back to the initial position. A groove for accommodating the baffle 150 may be provided at the corresponding position of the pushing block 130 and the baffle 150, so that the pushing block 130 can extend out of the base 140 in the second direction Y relative to the base 140, and the stroke of the pushing block 130 can be increased. A clamping groove may be provided at the position where the base 140 is connected to the baffle 150. The clamping groove penetrates through both sides of the base 140 in the first direction X. The size of the clamping groove in the first direction X may be matched with the size of the baffle 150 in the first direction X. The baffle 150 can be clamped in the clamping groove, and the baffle 150 can slide in the clamping groove in the second direction Y to facilitate the assembly of the baffle 150.

[0046] In some embodiments, the elastic member 160 includes a spring. The pushing block 130 has a compression groove 135. The elastic member 160 is at least partially located in the compression groove 135. The elastic member 160 is elastically supported between the baffle 150 and the bottom wall of the compression groove 135. The compression groove 135 is located in the bottom wall of the groove at the corresponding position of the pushing block 130 and the baffle 150. The elastic member 160 is placed in the compression groove 135, which can limit the position of the elastic member 160 in the second direction Y and the third direction Z and prevent the elastic member 160 from falling between the baffle 150 and the pushing block 130. The radial dimension of the elastic member 160 can be close to the radial dimension of the compression groove 135, so that the elastic member 160 can be located in the compression groove 135, and the radial direction of the elastic member 160 can always be parallel or nearly parallel to the second direction Y, thereby ensuring the stability of the elastic member 160 supported between the baffle 150 and the pushing block 130.

[0047] See Figure 5 , Figure 5 is the third perspective view of an embodiment of the pushing mechanism provided by the present application.

[0048] In some embodiments, the base 140 includes a second limiting block 141. The second limiting block 141 and the first limiting block 120 are spaced apart in the second direction Y to form a second limiting groove 142 extending in the first direction X. The wedge block 110 moves within the second limiting groove 142. The surface of the wedge block 110 opposite to the first inclined surface 111 can be parallel to the surface of the second limiting block 141 close to the wedge block 110, and the surface of the wedge block 110 opposite to the first inclined surface 111 can be slidably connected to the surface of the second limiting block 141 close to the wedge block 110. So that the wedge block 110 slides in the first direction X with the surface of the second limiting block 141 close to the wedge block 110 as the reference surface. During the process of the wedge block 110 moving in the first direction X to push the push block 130, the second limiting block 141 can provide a supporting force for the wedge block 110, thereby improving the stability when the push block 130 fixes the abutted member 20. The second limiting block 141 may be provided with a screw hole penetrating through two surfaces in the third direction Z. The base 140 is provided with a corresponding screw hole for the screw hole of the second limiting block 141. The second limiting block 141 and the base 140 are fixed together by screws. A positioning hole may also be provided at the fixed end of the second limiting block 141 and the base 140. The second limiting block 141 can be pre-fixed to the base 140 through the positioning hole and the positioning pin first, and then further fixed by screws.

[0049] In some embodiments, the pushing mechanism 10 includes a driving cylinder 170. The driving cylinder 170 is connected to the wedge block 110. The driving cylinder 170 is used to drive the wedge block 110 to move in the first direction X. The driving cylinder 170 is fixed to the first limiting block 120 and the second limiting block 141. The wedge block 110 can be connected to the driving cylinder 170 through a telescopic rod. The driving cylinder 170 drives the telescopic rod to expand and contract in the first direction X, thereby driving the wedge block 110 to move in the first direction X. The driving cylinder 170 can be fixed to the first limiting block 120, the second limiting block 141 and the base 140 simultaneously in the first direction X. Thus, the fixing effect of the driving cylinder 170 is better, and it can also ensure that when the driving cylinder 170 drives the wedge block 110 to move in the first direction X, the driving cylinder 170, the first limiting block 120, the second limiting block 141 and the base 140 can be in a relatively static state, thereby making the pushing mechanism 10 more stable during operation.

[0050] In some embodiments, the push mechanism 10 further includes a side push block 180, which is connected to one end of the push block 130 away from the wedge block 110, and extends along the second direction Y. The push block 130 abuts against the abutted member 20 through the side push block 180. The size of the side push block 180 in the first direction X may be larger than the size of the push block 130 in the first direction X, so as to increase the contact area between the push mechanism 10 and the abutted member 20, so as to make the fixation of the abutted member 20 more stable. The extension of the side push block 180 in the second direction Y is equivalent to increasing the push distance of the push mechanism 10 in the second direction Y. When the abutted member 20 is small in size, the side push block 180 can also effectively fix the abutted member 20. The side push block 180 may be provided with a screw hole in the second direction Y, and the push block 130 may be provided with a screw hole corresponding to the side push block 180 in the second direction Y. The side push block 180 can be fixed to the push block 130 by screws.

[0052] In some embodiments, the side top block 180 includes a first side top 181 and a second side top 182 connected to each other, the first side top 181 and the second side top 182 are both extended along the first direction X, and the first side top 181 protrudes from the second side top 182 in the second direction Y in a direction away from the first limit block 120. When the side top block 180 abuts against the abutted member 20, the edge of the abutted member 20 may be tilted upward. At this time, the tilted edge of the abutted member 20 can abut against the first side top 181 and the second side top 182 at the same time, and the abutted member 20 is fixed at the corner where the first side top 181 and the second side top 182 are connected. The first side top 181 can fix the abutted member 20 in the first direction X, and the second side top 182 can fix the abutted member 20 in the third direction Z. Thus, the side top block 180 can not only fix the abutted member 20 in the second direction Y, but also prevent the abutted member 20 from falling off the push-up mechanism 10 due to the upward warping of the edge of the abutted member 20. This embodiment is more suitable for fixing the abutted member 20 with a flat surface. When the side top block 180 abuts against the abutted member 20, it has a larger contact area, and has a better fixing effect on the abutted member 20 with a flat surface.

[0053] In some embodiments, one side of the top of the first side 181 away from the first limiting block 120 is serrated and extends along the first direction X. When the piece to be abutted 20 is a blank piece, that is, when the surface of the piece to be abutted 20 is uneven, the contact area between the piece to be abutted 20 and the side top block 180 is limited. The uneven upper surface of the piece to be abutted 20 in the third direction Z abuts against the lower side of the serrated top of the first side 181 in the third direction Z. The serrated top of the first side 181 can increase the friction with the piece to be abutted 20, thereby reducing the possibility of the piece to be abutted 20 sliding when being abutted, and further ensuring high precision in processing the piece to be abutted 20 such as polishing and cutting.

[0054] In some embodiments, the pushing mechanism 10 may further include a protective cover (not shown in the figure). The protective cover and the base 140 form a cavity for installing the second limiting block 141, the wedge block 110, the pushing block 130, and the first limiting block 120 inside the cavity. The size of the projection of the protective cover in the third direction Z may be the same as that of the base 140 to cover the upper part of the pushing mechanism 10. One side of the protective cover away from the driving cylinder 170 in the first direction X may extend towards the base 140 in the third direction Z to cover the exposed parts of structures such as the first limiting block 120 and the second limiting block 141 in the first direction X. The protective cover can not only prevent debris generated during the processing of the piece to be abutted 20 from entering the inside of the pushing mechanism 10, but also improve the safety of the pushing mechanism 10.

[0055] In summary, during the movement of the wedge block 110 in the first direction X, by abutting against the abutting arc surface 131, the pushing block 130 is pushed to move in the second direction Y. The pushing block 130 deflects in the first limiting groove 121 with the abutting arc surface 131 as the fulcrum, thereby increasing the contact surface with the piece to be abutted 20. As a result, the accuracy of fixing the piece to be abutted 20 is higher and it is fixed more firmly.
