Technical Field
[0001] This application relates to the technical field of jigs, and more particularly, to a clamping device. Background Art
[0002] The existing clamping devices are cumbersome to operate when clamping a target piece, and when the target piece is small, the problem of inaccurate positioning easily occurs, affecting work efficiency. Utility Model Content
[0003] This application provides a clamping device to solve the problem that the existing clamping device is prone to inaccurate positioning and affects work efficiency.
[0004] This application provides a clamping device. The clamping device is used to clamp a target piece. The clamping device includes a sleeve, a clamping assembly, a ejector rod, and a limiting member. The sleeve is provided with an inner hole, and the axis of the inner hole is along a first direction. The clamping assembly includes a clamping member and an elastic member. The clamping member has a first end and a second end opposite to each other along the first direction. The first end is slidably fitted to the sleeve along a second direction, and the second end is provided with a clamping portion. The elastic member elastically abuts against the clamping member to apply an elastic force along the second direction to the clamping member, so that the clamping portion tends to displace in the direction of the target piece. The ejector rod is slidably fitted to the inner hole along the first direction, and the ejector rod forms an inclined wedge fit with the first end of the clamping member. The limiting member is slidably fitted to the sleeve along the second direction. The clamping device has an initial state and a clamping state. In the initial state, the limiting member limits the ejector rod at a position close to the clamping assembly along the first direction to limit the clamping member at a position away from the target piece. In the clamping state, the limiting member releases the limit on the ejector rod, the ejector rod is located at a position away from the clamping assembly along the first direction, and the elastic member elastically presses the clamping member against the target piece.
[0005] When the clamping device in this application is in use, when the clamping device is in the initial state, the limiting member limits the ejector rod, causing the ejector rod to press down the clamping member, and the clamping member moves away from the center of the sleeve, releasing the target piece. When the clamping device is in the clamping state, the limiting member releases the limit on the ejector rod, the ejector rod moves upward, and the clamping member is abutted by the elastic member to approach the center of the sleeve and clamp the target piece. It is convenient to use and has precise clamping and positioning for small-sized objects.
[0006] In a possible implementation manner, one end of the ejector rod away from the clamping assembly has a connected first end face and a first inclined face. The first end face is perpendicular to the first direction, and the first inclined face intersects the first direction obliquely. One end of the limiting member close to the ejector rod is provided with a second end face and a second inclined face. The second end face is perpendicular to the first direction, and the second inclined face intersects the first direction obliquely. And the second inclined face forms an inclined wedge fit with the first inclined face. When the limiting member displaces along the second direction until the first end face abuts against the second end face, the ejector rod is limited by the limiting member. When the limiting member displaces along the second direction until the first inclined face cooperates with the second inclined face, the ejector rod is unlocked.
[0007] In a possible implementation, the clamping device further includes a reset ejector rod. The reset ejector rod is slidably disposed in the inner hole along a first direction, and the reset ejector rod is disposed on the side of the ejector rod away from the clamping assembly along the first direction. The limiting member further includes a third inclined surface, and the third inclined surface is disposed on the side of the limiting member close to the reset ejector rod. The reset ejector rod further includes a fourth inclined surface, and the fourth inclined surface is disposed on the side of the reset ejector rod close to the limiting member. The third inclined surface and the fourth inclined surface are in inclined wedge fit. The limiting member can move between a limiting position and a reset position along a second direction. When the limiting member is in the limiting position, the first end face abuts against the second end face to limit the ejector rod. When the fourth inclined surface presses down the third inclined surface along the first direction, the limiting member moves along the second direction towards the reset position side to release the limitation on the ejector rod.
[0008] In a possible implementation, the reset ejector rod further includes a connecting portion, and the connecting portion is disposed on the side of the reset ejector rod away from the ejector rod along the first direction. The sleeve further includes a top end, and a connecting hole is provided in the top end. The clamping device further includes a fixing cover, and the fixing cover is disposed on the side of the connecting portion away from the ejector rod. The connecting portion is slidably fitted in the connecting hole.
[0009] In a possible implementation, the first end further includes an abutting surface, and the abutting surface is disposed on the side of the first end facing the ejector rod. The ejector rod includes a pressing surface, and the pressing surface is disposed on the side of the ejector rod facing the clamping member along the first direction. The pressing surface is in fit with the abutting surface so that when the ejector rod presses down the clamping member, the clamping member can move along the second direction.
[0010] In a possible implementation, the sleeve is a cylindrical tubular structure, and the second direction is the radial direction of the sleeve. There are multiple clamping members, and the multiple clamping members are arranged at intervals in the circumferential direction and can move closer to each other inwardly in the radial direction to clamp the target member, or move away from each other in the radial direction to release the target member.
[0011] In a possible implementation, the target member includes a cylindrical section. The radially inner surface of the clamping member is an abutting surface for abutting against the cylindrical section.
[0012] In a possible implementation, the clamping device further includes a guide rod. The guide rod is disposed along the second direction, one end of the guide rod is connected to the sleeve, and the other end extends into the inner hole along the second direction. The first end is slidably fitted with the guide rod, and an elastic member is disposed on the guide rod. The elastic member is disposed between the first end and the sleeve so that the clamping member has a tendency to move away from the elastic member.
[0013] In a possible implementation, the ejector rod further has a fitting groove. The fitting groove is provided at one end of the ejector rod close to the clamping member along the first direction and extends along the first direction towards the end away from the clamping member. The guide rod corresponds to the fitting groove along the first direction.
[0014] In a possible implementation, the sleeve is provided with a sliding groove that penetrates through the side wall of one side of the sleeve along the second direction. The limiting member is slidably fitted in the sliding groove. The limiting member is further provided with a limiting pin groove that is perpendicular to the second direction. The sleeve further includes a limiting pin that is fitted in the limiting pin groove, and the limiting pin cooperates with the limiting pin groove to limit the movement of the limiting member in the second direction.

[0066] Embodiment
[0067] See Figure 1 and Figure 2, this embodiment provides a clamping device 100 for clamping a target 10. The clamping device 100 includes a sleeve 11, a clamping assembly 12, a push rod 13, and a limiting member 14. The sleeve 11 is provided with an inner hole 111, and the axis of the inner hole 111 is along the first direction Z. The clamping assembly 12 includes a clamping member 121 and an elastic member 123. The clamping member 121 has a first end 1211 and a second end 1213 opposite to each other along the first direction Z. The first end 1211 is slidably engaged with the sleeve 11 along the second direction X, and a clamping portion 122 is provided at the second end 1213. The elastic member 123 elastically abuts against the clamping member 121 for applying an elastic force along the second direction X to the clamping member 121, so that the clamping portion 122 tends to displace in the direction of clamping the target 10. The push rod 13 is slidably engaged with the inner hole 111 along the first direction Z, and the push rod 13 forms an inclined wedge fit with the first end 1211 of the clamping member 121. The limiting member 14 is slidably engaged with the sleeve 11 along the second direction X.
[0068] See Figures 3 to 6 , in this embodiment, the clamping device 100 has an initial state (see Figure 3 and Figure 4 ) and a clamping state (see Figure 5 and Figure 6 ). In the initial state, the limiting member 14 limits the push rod 13 at a position close to the clamping assembly 12 along the first direction Z to limit the clamping member 121 at a position away from the target 10. In the clamping state, the limiting member 14 releases the limit on the push rod 13, the push rod 13 is located at a position away from the clamping assembly 12 along the first direction Z, and the elastic member 123 elastically presses the clamping member 121 against the position of clamping the target 10.
[0069] In this embodiment, in the initial state, by pressing down the clamping member 121 by the push rod 13 along the first direction Z, the clamping member 121 is limited on the side away from the inner hole 111 along the second direction X, and the clamping member 121 is in a released state.
[0070] In this embodiment, by providing an elastic force by the elastic member 123, the clamping member 121 has a tendency to move towards the target 10 side, and the target 10 can be released from the limit by pressing down the push rod 13, with convenient operation and more accurate clamping and positioning.
[0071] In this embodiment, the push rod 13 is slidably disposed in the inner hole 111, which is convenient for positioning and pressing down.
[0072] In this embodiment, one end of the ejector rod 13 away from the clamping assembly 12 has a connected first end face 131 and a first inclined face 132. The first end face 131 is perpendicular to the first direction Z, and the first inclined face 132 intersects the first direction Z obliquely. One end of the limiting member 14 close to the ejector rod 13 is provided with a second end face 141 and a second inclined face 142. The second end face 141 is perpendicular to the first direction Z, and the second inclined face 142 intersects the first direction Z obliquely. And the second inclined face 142 is in wedge fit with the first inclined face 132. When the limiting member 14 is displaced along the second direction X until the first end face 131 abuts against the second end face 141 (see Figure 5 ), the ejector rod 13 is limited by the limiting member 14. When the limiting member 14 is displaced along the second direction X until the first inclined face 132 cooperates with the second inclined face 142 (see Figure 3 ), the ejector rod 13 is unlocked.
[0073] In this embodiment, the first inclined face 132 and the second inclined face 142 are arranged oppositely, so that the first inclined face 132 can abut against the second inclined face 142 in the clamping state, and the first end face 131 can abut against the second end face 141 in the initial state, so that the limiting member 14 limits the movement of the ejector rod 13 along the first direction Z.
[0074] In this embodiment, the abutment of the first end face 131 and the second end face 141 realizes the limitation. After the limiting member 14 moves, the first end face 131 and the second end face 141 are separated, and the abutment of the first inclined face 132 and the second inclined face 142 realizes the unlocking. The structure is simple and the operation is convenient. Among them, the included angle between the first end face 131 and the first inclined face 132 is an obtuse angle, and the included angle between the second end face 141 and the second inclined face 142 is an obtuse angle.
[0075] In this embodiment, the clamping device 100 further includes a reset ejector rod 15. The reset ejector rod 15 is slidably fitted in the sleeve 11 along the first direction Z. The limiting member 14 further includes a third inclined face 143, and the third inclined face 143 is arranged on the side of the limiting member 14 close to the reset ejector rod 15. The reset ejector rod 15 further includes a fourth inclined face 151, and the fourth inclined face 151 is arranged on the side of the reset ejector rod 15 close to the limiting member 14. The third inclined face 143 is in wedge fit with the fourth inclined face 151.
[0076] In this embodiment, the limiting member 14 can move between a limiting position and a reset position along the second direction X. When the limiting member 14 is in the limiting position (see Figure 5 ), the first end face 131 abuts against the second end face 141 to limit the ejector rod 13. When the fourth inclined face 151 presses the third inclined face 143 along the first direction Z (see Figure 3 ), the limiting member 14 moves along the second direction X towards the reset position side, releasing the limitation on the ejector rod 13.
[0077] In this embodiment, when the limiting member 14 is in the limiting position, the first end face 131 abuts against the second end face 141, and at the same time, the third inclined surface 143 abuts against the fourth inclined surface 151. Then, pressing down the reset ejector rod 15 can make the third inclined surface 143 slide relative to the fourth inclined surface 151 and move towards the upper part of the fourth inclined surface 151 in the vertical direction. At the same time, the first end face 131 is separated from the second end face 141, and the first inclined surface 132 abuts against the second inclined surface 142, and the limiting member 14 unlocks the limitation of the ejector rod 13.
[0078] In this embodiment, the first end 1211 further includes an abutting surface 1212, and the abutting surface 1212 is arranged on the side of the first end 1211 facing the ejector rod 13. The ejector rod 13 includes a pressing surface 134, and the pressing surface 134 is arranged on the side of the ejector rod 13 facing the clamping member 121 along the first direction Z. The abutting surface 1212 cooperates with the pressing surface 134 to enable the clamping member 121 to move along the second direction X when the ejector rod 13 presses down the clamping member 121. Wherein, the pressing surface 134 is an inclined surface, and the abutting surface 1212 and the pressing surface 134 are in an inclined wedge fit.
[0079] See Figure 7 , in this embodiment, the reset ejector rod 15 further includes a connecting portion 152, and the connecting portion 152 is arranged on the side of the reset ejector rod 15 away from the ejector rod 13 along the first direction Z (see Figure 3 ). The sleeve 11 further includes a top end 112, and a connecting hole 113 is provided in the top end 112. The clamping device 100 further includes a fixing cover 16, and the fixing cover 16 is arranged on the side of the connecting portion 152 away from the ejector rod 13. The connecting portion 152 is slidably fitted in the connecting hole 113.
[0080] In this embodiment, the reset ejector rod 15 is slidably fitted in the inner hole 111, and the first inclined surface 132, the second inclined surface 142, the third inclined surface 143 and the fourth inclined surface 151 are arranged on the same side of the sleeve 11, which is convenient for fitting and positioning.
[0081] See Figure 8 , in this embodiment, the sleeve 11 is a cylindrical tubular structure, and the second direction X is the radial direction of the sleeve 11. There are a plurality of clamping members 121, and the plurality of clamping members 121 are arranged at intervals in the circumferential direction and can move closer to each other radially inward to clamp the target member 10, or move away from each other radially to release the target member 10. In this embodiment, four clamping members 121 are arranged in the circumferential direction of the sleeve 11, and the four clamping members 121 are evenly distributed in the circumferential direction to clamp the target member 10 at the central position of the sleeve 11.
[0082] In other embodiments, the number of the clamping members can be 2, 3, 5 or more.
[0083] See Figure 8 and Figure 9, in this embodiment, the target part 10 includes a cylindrical section 101 and a bottom plate 102. The bottom plate 102 is circular, and the cylindrical section 101 protrudes from the bottom plate 102. The cylindrical section 101 and the bottom plate 102 are concentrically arranged so that the clamping device 100 can position the target part 10 by clamping the cylindrical section 101. The radially inner surface of the clamping member 121 is the abutting top surface 1221. In the clamping state, the abutting top surface 1221 abuts against the cylindrical section 101 of the target part 10 to clamp the target part 10.
[0084] In other embodiments, the shape of the clamping part of the clamping member can be set according to the shape of the clamped part of the target part.
[0085] In this embodiment, the clamping device 100 further includes a guide rod 17. The guide rod 17 is arranged along the second direction X. One end of the guide rod 17 is connected to the sleeve 11, and the other end extends into the sleeve 11 along the second direction X. The first end 1211 is slidably fitted to the guide rod 17. The elastic member 123 is cooperatively arranged on the guide rod 17. The elastic member 123 is arranged between the first end 1..
[0086] In this embodiment, the elastic member 123 is a spring. The spring is sleeved on the guide rod 17 to provide an elastic force radially inward of the sleeve 11 to clamp the target part 10.
[0087] In this embodiment, the ejector rod 13 is further provided with a mating groove 133. The mating groove 133 is opened at one end of the ejector rod 13 close to the clamping member 121 along the first direction Z and extends along the first direction Z away from the clamping member 121. The guide rod 17 corresponds to the mating groove 133 along the first direction Z.
[0088] In this embodiment, when the ejector rod 13 is pressed down, the guide rod 17 can move along the first direction Z and extend into the mating groove 133 without affecting the abutment between the clamping member 121 and the ejector rod 13.
[0089] See Figure 10 , in this embodiment, the sleeve 11 is provided with a sliding groove 114. The sliding groove 114 penetrates through the side wall of one side of the sleeve 11 along the second direction X. The limiting member 14 is slidably fitted to the sliding groove 114. The clamping device 100 further includes a limit pin 115. The limit pin 115 is fixedly connected to the sleeve 11. The limiting member 14 is further provided with a limit pin groove 116. The limit pin groove 116 is perpendicular to the second direction X. The limit pin 115 is fitted to the limit pin groove 116, and the limit pin 115 can move along the limit pin groove 116 in the second direction X.
[0090] In this embodiment, the limit pin 115 can limit the movement range of the limiting member 14 through the limit pin groove 116, so that the limiting member 14 is in the limit position (see Figure 5 ) and the reset position (seeFigure 3 ) move between them. When the limit pin 115 abuts against the limit pin groove 116 and approaches the groove wall on the side closer to the center of the sleeve 11 in the second direction X, the limit pin 115 is in the reset position, the ejector rod 13 moves upward, the clamping member 121 tightens, and the clamping device 100 is in the clamping state. When the limit pin 115 abuts against the limit pin groove 116 and approaches the groove wall on the side away from the center of the sleeve 11 in the second direction X, the limit pin 115 is in the limit position, the ejector rod 13 presses downward, the clamping member 121 loosens, and the clamping device 100 is in the initial state.
[0091] In summary, the embodiment of the present application provides a clamping device 100. The elastic member 123 provides an elastic force for the elastic member 123 in the second direction X to clamp the target member 10. At the same time, the ejector rod 13 can move along the first direction Z to drive the clamping member 121 to retreat along the second direction X to unlock and clamp the target member 10, and then be limited by the limiting member 14, achieving the effects of clamping and unlocking, with convenient operation and accurate clamping and positioning.
