Description

Technical Field

[0001] This application relates to the technical field of fixtures, and more particularly, to a clamping device and an assembly device. Background Art

[0002] When some existing clamping devices clamp small parts to the assembly position, problems such as inaccurate positioning and part dropping are likely to occur, affecting work efficiency. Summary of the Utility Model

[0003] This application provides a clamping device and an assembly device to solve the problems of inaccurate positioning and dropping of existing clamping devices, which affect work efficiency.

[0004] This application provides a clamping device. The clamping device is used to clamp a workpiece. The clamping device includes a base, a first handle, a first clamping member, a second handle, two second clamping members, a first elastic member, and a second elastic member. The first handle is rotatably mounted on the base. The first clamping member is slidably engaged with the base in a first direction. The first clamping member abuts against the first handle and can slide in the first direction under the drive of the first handle to abut against the workpiece in the first direction. The second handle includes a pushing portion and a manipulating handle. The pushing portion is slidably engaged with the base in the first direction. The manipulating handle is connected to the pushing portion and corresponds to the first handle in the first direction. The two second clamping members are respectively slidably engaged with the base in a second direction, and the two second clamping members are respectively wedge-fitted on both sides of the pushing portion in the second direction, so that the second handle can move in the first direction to drive the two second clamping members to approach or separate from each other in the second direction to clamp the workpiece in the second direction. Wherein, the second direction is perpendicular or obliquely intersects with the first direction. The first elastic member elastically abuts between the first clamping member and the base in the first direction, so that the first clamping member has a tendency to move towards the workpiece side in the first direction. The second elastic member elastically abuts between the second clamping member and the base, so that the second handle has a tendency to move in the second direction to cause the two second clamping members to approach each other.

[0005] This application drives the first clamping member to clamp the workpiece between the first clamping member and the base in the first direction through the first handle, and the second handle wedge-fits the two second clamping members to drive the two second clamping members to clamp the workpiece in the second direction. At the same time, the first handle corresponds to the second handle in the first direction, so that the first handle can rotate and drive the second handle to move in the first direction, realizing the clamping effect on the workpiece in two directions, with simple operation, accurate positioning, and not likely to drop.

[0006] In a possible implementation, the first handle includes a rotating shaft, an operating end, and a abutting end. The rotating shaft is rotatably fitted to the base. The operating end and the abutting end are respectively located on both sides of the rotating shaft. The first clamping member includes a first clamping portion and a sliding block. The first clamping portion is connected to the sliding block. The sliding block is provided with an abutting groove extending along a first direction. The first clamping portion is configured to abut the workpiece against the base along the first direction. The abutting end extends into the abutting groove and is limited between the opposite groove surfaces of the abutting groove along the first direction.

[0007] In a possible implementation, the base further includes a convex wall provided at one end of the base away from the first clamping member along the first direction, and the convex wall corresponds to the first clamping portion along the first direction.

[0008] In a possible implementation, two first grooves are formed on a side of the pushing portion opposite to the operating handle. The first grooves extend obliquely and divide the pushing portion into a central convex block and side convex blocks on both sides. The second clamping member protrudes with a first convex block along a second direction, and a second convex block protrudes from a free end of the first convex block to form a second groove corresponding to a side surface of the second clamping member. The projections of the first grooves and the second grooves along the vertical direction coincide, so that the side convex blocks can extend into the second grooves and the second convex blocks can extend into the first grooves, thereby forming an inclined wedge fit between the two second clamping members and the pushing portion.

[0009] In a possible implementation, the second clamping member includes a sliding portion, a clamping portion, a third elastic member, and a floating push head. The sliding portion is connected to the clamping portion. The sliding portion is slidably fitted to the base along the second direction.

The floating push head is slidably fitted to the installation groove. The third elastic member is installed in the installation groove, and two ends of the third elastic member respectively abut against the bottom surface of the installation groove and the bottom surface of the floating push head opposite to the bottom surface of the installation groove along the vertical direction. The pushing portion can drive the two second clamping members to approach each other along the second direction through the inclined wedge fit to clamp the workpiece between the two floating push heads.

[0010] In a possible implementation, the base is provided with a suction hole corresponding to the workpiece along the vertical direction. The clamping device further includes a suction assembly connected to the suction hole.

[0011] In a possible implementation, the base includes a top cover, an intermediate block, and a bottom cover. The top cover is connected to the intermediate block to form a first accommodation space. The first clamping member is slidably disposed in the first accommodation space and can move between opposite side walls of the accommodation space along the first direction. The bottom cover is connected to a side of the intermediate block opposite to the top cover to form a second accommodation space. The pushing portion is slidably disposed in the second accommodation space and can move between opposite side walls of the second accommodation space along the first direction.

[0012] In a possible implementation, the middle block is further provided with a first through hole, and the first handle extends vertically out of the first through hole. The bottom cover is further provided with a second through hole, and the second through hole corresponds to the first through hole vertically. The first handle and the operating handle extend vertically out of the second through hole. The operating handle is provided with a mating groove, and the mating groove corresponds to the first handle in the first direction, so that the first handle can rotate into the mating groove and move along the first direction together with the operating handle, thereby driving the second clamping member to move away from the workpiece along the second direction.

[0013] In a possible implementation, the workpiece includes a plate body and a connecting portion, and the plate body extends along the second direction. The connecting portion is connected to the middle portion of the plate body along the second direction. The base is further provided with a third groove, and the third groove is provided in the middle of the base close to the workpiece.

[0093] Embodiment

[0094] Referring to Figure 1 and Figure 2 In this embodiment, an assembly device 1000 is provided for pressing and installing a workpiece 11 onto a target part 10. The assembly device 1000 includes a base 100, a fixture 200, a clamping device 500, a support member 300, and a pressing component 400. The fixture 200 is installed on the base 100, and the fixture 200 is used for clamping the target part 10. The clamping device 500 is used for clamping the workpiece 11. The workpiece 11 corresponds to the target part 10 along the vertical direction Z. The support member 300 is installed on the base 100. The support member 300 includes a column 301 and a cross beam 302. The two columns 301 are installed on both sides of the base 100 along the second direction Y, and the column 301 elastically supports the cross beam 302 along the vertical direction Z. The cross beam 302 is erected on the two columns 301. The clamping device 500 is installed in the middle of the lower side of the cross beam 302 along the vertical direction Z. The workpiece 11 is clamped on the clamping device 500, and the workpiece 11 faces the target part 10 along the vertical direction Z. The cross beam 302 is further provided with a third through hole 3021. The third through hole 3021 corresponds to the first handle 13 and the operating handle 152 along the vertical direction Z, so that the first handle 13 and the operating handle 152 can extend out of the third through hole 3021 along the vertical direction Z. The pressing component 400 can press down the cross beam 302 along the vertical direction Z, and further press down the clamping device 500, so that the workpiece 11 is pressed against and fitted to the target part 10. The pressing component 400 includes a pressing cylinder 401 and a pressing part 402. The pressing part 402 is connected to the lower end of the pressing cylinder 401 along the vertical direction Z. The pressing part 402 has a pressing surface 4021 and a square groove 4022. The square groove 4022 is opened in the middle of the pressing part 402 along the second direction Y. The square groove 4022 corresponds to the third through hole 3021 along the vertical direction Z, so that when the pressing part 402 presses down, the first handle 13 and the operating handle 152 can extend into the square groove 4022 along the vertical direction Z. The square groove 4022 can move along the first direction X and press against and drive the operating handle 152 and the first handle 13 with its groove wall along the first direction X, so as to unlock the clamping of the workpiece 11 by the clamping device 500.

[0095] In this embodiment, the clamping device 500 clamps the workpiece 11 along the vertical direction Z, so that the workpiece 11 corresponds to the target part 10 along the vertical direction Z. The pressing component 400 presses the clamping device 500 by pressing down the support member 300, so that the workpiece 11 is pressed and fitted onto the target part 10. In this way, the workpiece 11 can be installed onto the target part 10 along the vertical direction Z, and the operation is simple.

[0096] Referring to Figures 3 to 6, in this embodiment, the clamping device 500 is used to clamp the workpiece 11. The clamping device 500 includes a base 12, a first handle 13, a first clamping member 14, a second handle 15, two second clamping members 16, a first elastic member 17, and a second elastic member 18. The first handle 13 is rotatably mounted on the base 12. The first clamping member 14 is slidably engaged with the base 12 along the first direction X. The first clamping member 14 abuts against the first handle 13 and can slide along the first direction X under the drive of the first handle 13 to abut against the workpiece 11 along the first direction X. The second handle 15 includes a pushing portion 151 and a manipulation handle 152. The pushing portion 151 is slidably engaged with the base 12 along the first direction X. The manipulation handle 152 is connected to the pushing portion 151 and corresponds to the first handle 13 along the first direction X. The two second clamping members 16 are respectively slidably engaged with the base 12 along the second direction Y, and the two second clamping members 16 are respectively wedge-fitted on both sides of the pushing portion 151 along the second direction Y, so that the second handle 15 can move along the first direction X to drive the two second clamping members 16 to approach or separate from each other along the second direction Y to clamp the workpiece 11 along the second direction Y. Wherein, the second direction Y is perpendicular or obliquely intersects with the first direction X. The first elastic member 17 elastically abuts between the first clamping member 14 and the base 12 along the first direction X, so that the first clamping member 14 has a tendency to move toward the workpiece 11 along the first direction X. The second elastic member 18 elastically abuts between the second clamping member 16 and the base 12, so that the second handle 15 has a tendency to move along the second direction Y, causing the two second clamping members 16 to have a tendency to approach each other.

[0097] In this embodiment, the first handle 13 drives the first clamping member 14 to clamp the workpiece 11 between the first clamping member 14 and the base 12 along the first direction X. The second handle 15 is wedge-fitted with the two second clamping members 16 to drive the two second clamping members 16 to clamp the workpiece 11 along the second direction Y. At the same time, the first handle 13 corresponds to the second handle 15 along the first direction X, and the second handle 15 can move along the first direction X and drive the first handle 13 to move, realizing the clamping effect on the workpiece 11 in two directions, facilitating the clamping of small workpieces 11, with simple operation, accurate positioning, and not easy to fall off.

[0098] In this embodiment, the first elastic member 17 is a spring. The first elastic member 17 abuts against the first clamping member 14 along the first direction X, so that the first clamping member 14 has a tendency to approach the workpiece 11 along the first direction X, and clamps the workpiece 11 between the first clamping member 14 and the base 12.

[0099] In this embodiment, the second elastic member 18 is a spring. The second elastic member 18 abuts against the second handle 15 along the first direction X, so that the second handle 15 has a tendency to move away from the second clamping member 16, and the two second clamping members 16 are caused to approach each other and clamp the workpiece 11 through wedge-fitting.

[0100] In this embodiment, by providing the first elastic member 17 and the second elastic member 18, the first clamping member 14 and the second clamping member 16 can be clamped without external force operation, and at the same time, the unlocking operation is simplified. By operating the first handle 13 and the second handle 15, the clamping actions of the first clamping member 14 and the second clamping member 16 are changed to clamp and unlock the workpiece 11.

[0101] In this embodiment, the operating handle 152 is provided with a mating groove 153, and the mating groove 153 corresponds to the first handle 13 in the first direction X, so that the first handle 13 can enter the mating groove 153 and rotate to drive the operating handle 152. In this way, the first clamping member 14 and the second clamping member 16 can be operated simultaneously by operating the operating handle 152, and the workpiece 11 can be clamped in the first direction X and the second direction Y.

[0102] See Figure 7 , in this embodiment, the first handle 13 includes a rotating shaft 131, an operating end 132, and an abutting end 133. The base 12 is provided with a shaft hole 1242 (see Figure 9 ), and the rotating shaft 131 is rotatably fitted to the base 12 through the shaft hole 1242. The operating end 132 and the abutting end 133 are respectively located on both sides of the rotating shaft 131. The first clamping member 14 includes a first clamping portion 141 and a sliding block 142, and the first clamping portion 141 is connected to the sliding block 142. The sliding block 142 is provided with an abutting groove 1421, and the abutting groove 1421 extends in the first direction X. The first clamping portion 141 is used to abut the workpiece 11 against the base 12 in the first direction X. The abutting end 133 extends into the abutting groove 1421 and is limited between the opposite side surfaces of the abutting groove 1421 in the first direction X. The abutting end 133 can rotate along the rotating shaft 131 under the drive of the operating end 132, and then abut against the two side walls of the abutting groove 1421 in the first direction X, driving the sliding block 142 to move in the first direction X.

[0103] In this embodiment, the first clamping portion 141 is connected to the sliding block 142 and extends along the vertical direction Z. The first clamping portion 141 is columnar, and the side surface of the first clamping portion 141 in the first direction X is used to abut and clamp the target member 10. The number of columns of the first clamping portion 141 is one, two, or more. It can be understood that the shape of the first clamping portion 141 can also be conical, strip-shaped, or other shapes.

[0104] See Figure 8 and Figure 9 , in this embodiment, the base 12 further includes a convex wall 121, and the convex wall 121 is provided at one end of the base 12 away from the first clamping member 14 in the first direction X (see Figure 3 ), and the convex wall 121 corresponds to the first clamping portion 141 in the first direction X.

[0105] In this embodiment, the convex wall 121 protrudes from the surface of the base 12 along the vertical direction Z, and the side surface of the convex wall 121 faces the first clamping portion 141, so as to clamp the workpiece 11 between the convex wall 121 and the first clamping portion 141.

[0106] In this embodiment, the end surface of the first clamping portion 141 (see Figure 7 ) along the vertical direction Z is substantially flush with the surface of the workpiece 11, and the end surface of the convex wall 121 protruding along the vertical direction Z is substantially flush with the surface of the workpiece 11, so as to facilitate the downward pressing of the workpiece 11 onto the target member 10.

[0107] In this embodiment, the base 12 is provided with a suction hole 122, and the suction hole 122 corresponds to the workpiece 11 along the vertical direction Z. The clamping device 500 further includes a suction assembly 19, and the suction assembly 19 is connected to the suction hole 122.

[0108] In this embodiment, the suction hole 122 includes three suction pipes 1221 and a confluence pipe 1222. The three suction pipes 1221 correspond to the workpiece 11 along the vertical direction Z, the confluence pipe 1222 is arranged along the second direction Y, one ends of the three suction pipes 1221 are respectively connected to the surface of the base 12, and the other ends are respectively connected to the confluence pipe 1222. The suction assembly 19 provides suction force by connecting to the confluence pipe 1222, so that the suction pipes 1221 adsorb the workpiece 11 along the vertical direction Z to prevent the workpiece 11 from falling along the vertical direction Z.

[0109] See Figure 9 , in this embodiment, the base 12 includes a top cover 123, an intermediate block 124, and a bottom cover 125. The top cover 123 is connected to the intermediate block 124 to form a first accommodation space 126, and the first clamping member 14 (see Figure 5 ) is slidably arranged in the first accommodation space 126 and can move between the opposite side walls of the accommodation space along the first direction X. The bottom cover 125 is connected to the side of the intermediate block 124 facing away from the top cover 123 to form a second accommodation space 127, and the pushing portion 151 (see Figure 5 ) is slidably arranged in the second accommodation space 127 and can move between the opposite side walls of the second accommodation space 127 along the first direction X.

[0110] In this embodiment, the intermediate block 124 is further provided with a first through hole 1241, and the first handle 13 (see Figure 5 ) can extend out of the first through hole 1241 along the vertical direction Z. The bottom cover 125 is further provided with a second through hole 1251, and the second through hole 1251 corresponds to the first through hole 1241 along the vertical direction Z. The first handle 13 and the operating handle 152 (see Figure 5 ) can extend out of the second through hole 1251 along the vertical direction Z.

[0111] See Figure 10 and Figure 11, in this embodiment, two first grooves 1511 are formed on the side of the pushing part 151 opposite to the operating handle 152. The first grooves 1511 extend obliquely and divide the pushing part 151 into a central convex block 1512 and side convex blocks 1513 on both sides. The second clamping member 16 protrudes with a first convex block 161 along the second direction Y, and a second convex block 162 protrudes from the free end of the first convex block 161, so as to form a second groove 163 corresponding to the side surface of the second clamping member 16. The projections of the first grooves 1511 and the second grooves 163 along the vertical direction Z coincide, so that the side convex blocks 1513 can extend into the second grooves 163, and the second convex blocks 162 can extend into the first grooves 1511, thereby enabling the two second clamping members 16 and the pushing part 151 to form an inclined wedge fit.

[0112] In this embodiment, one ends of the two first grooves 1511 are respectively connected to the two side surfaces of the pushing part 151 along the second direction Y, and the other ends of the two first grooves 1511 are respectively communicated with the side surface of the pushing part 151 close to the second clamping member 16 along the first direction X. When the two first grooves 1511 approach the second clamping member 16 along the first direction X, the distance between the two first grooves 1511 along the second direction Y gradually decreases. Thus, through the inclined wedge fit between the second clamping member 16 and the pushing part 151, the second clamping member 16 can approach or move away from each other along the second direction Y, realizing clamping or unlocking.

[0113] In this embodiment, the second clamping member 16 includes a sliding part 164, a clamping part 165, a third elastic member 166 and a floating push head 167. The sliding part 164 is connected to the clamping part 165, and the sliding part 164 is slidably fitted to the base 12 along the second direction Y. The clamping part 165 is provided with an installation groove 1651 on the end surface away from the sliding part 164 along the vertical direction Z. The floating push head 167 is slidably fitted to the installation groove 1651. The third elastic member 166 is installed in the installation groove 1651, and both ends of the third elastic member 166 respectively abut against the bottom surface of the installation groove 1651 and the bottom surface of the floating push head 167 opposite to the bottom surface of the installation groove 1651 along the vertical direction Z. The pushing part 151 can drive the two second clamping members 16 to approach each other along the second direction Y through the inclined wedge fit, so as to clamp the workpiece 11 between the two floating push heads 167.

[0114] In this embodiment, the two floating push heads 167 correspond to the workpiece 11 along the second direction Y, and the two second clamping members 16 approach each other, so that the workpiece 11 is clamped between the two opposite side surfaces of the two floating push heads 167. During the process of the workpiece 11 being pressed down, the floating push head 167 can elastically retreat to ensure that the workpiece 11 is pressed down to be combined with the target part 10.

[0115] In this embodiment, the third elastic member 166 uses a spring.

[0116] In other embodiments, the third elastic member 166 may also be other structures providing elasticity.
