Description

Technical Field

[0001] This utility model relates to the field of devices for clamping workpieces on processing equipment, and specifically to a device for clamping flat workpieces. Background Technology

[0002] When performing surface milling on large flat workpieces, the flat workpiece is fixed on the machine tool's worktable. The conventional practice is to place the flat workpiece directly on the machine tool's worktable, or to place several blocks of the same height on the machine tool's worktable to support the flat workpiece, and then use a clamping mechanism to press the flat workpiece onto the machine tool's worktable or the blocks.

[0003] Generally, the back of a flat workpiece that contacts the machine tool table or pad is not flat. Therefore, after pressing the flat workpiece onto the machine tool table or pad, it will be forced to elastically deform. Thus, after the milling pressure on the upper surface of the flat workpiece is released, it will spring back, resulting in a decrease in the flatness accuracy of the machined upper surface. Therefore, a suitable workpiece clamping device is needed to clamp the flat workpiece to improve machining accuracy. Furthermore, in actual operation, it is often necessary to machine flat workpieces of different shapes or sizes; therefore, the corresponding workpiece clamping device also needs to be versatile. Utility Model Content

[0004] This utility model provides a flat workpiece clamping device, which can clamp flat workpieces of different shapes or sizes to ensure the processing accuracy of the flat workpieces.

[0005] A flat workpiece clamping device for mounting on the worktable of a processing equipment, comprising:

[0006] Base plate;

[0007] The support assembly has at least two sets, each including a support mounting base and a support head. The support mounting base is mounted on the base plate, and the support head is mounted on the support mounting base. An elastic element is provided between the support head and the support mounting base. The support assembly supports the flat workpiece through the support head. A locking mechanism is also provided between the support head and the support mounting base for locking the position of the support head. The locking mechanism is mounted on the support mounting base and has an operating part.

[0008] The clamping mechanism, having at least two sets, is mounted on the base plate and is used to clamp the flat workpiece onto the support assembly;

[0009] The base plate has mounting holes for support components. The support mounting base is mounted on the base plate by support component mounting screws disposed in the mounting holes. There are multiple mounting holes for support components, so that the installation position of each set of support components is adjustable.

[0010] In one technical solution, the support mounting base includes a cylindrical body with a cylindrical bottom, the support head is inserted into the cylindrical body, the cylindrical body has a threaded through hole on the cylindrical wall, the locking mechanism is a tightening screw screwed into the threaded through hole, the tightening screw locks the support head by tightening the support head, and the end of the tightening screw away from the support head protrudes from the cylindrical body to form the operating part.

[0011] In one technical solution, one end of the support head is a round head, and the support head supports the flat workpiece through the round head.

[0012] In one technical solution, the base plate has mounting holes for a clamping mechanism. The clamping mechanism is mounted on the base plate by clamping mechanism mounting screws disposed in the mounting holes. Multiple mounting holes for the clamping mechanism are arranged so that the mounting position of each clamping mechanism is adjustable.

[0013] In one technical solution, the clamping mechanism includes a clamping mounting base and a driving device. The clamping mounting base includes at least two spaced vertical plates and a top plate connected to the same end of each vertical plate. The clamping mounting base is mounted on the bottom plate through the ends of the vertical plates away from the top plate. The driving device is disposed within the space enclosed by the top plate and the vertical plates, and the driving device is mounted on the top plate.

[0014] In one technical solution, the clamping mechanism includes a clamping mounting base and a driving device. The clamping mounting base is mounted on the base plate, and the driving device is mounted on the clamping mounting base. The driving device has an actuating arm that outputs driving force, and a pressure head is detachably mounted on the actuating arm. The pressure head is used to clamp the flat workpiece onto the support head under the drive of the driving device.

[0015] In one technical solution, the pressure head is detachably mounted on the actuator arm via a pressure head mounting screw, so that the pressure head can be rotated and its position adjusted with the pressure head mounting screw as the pivot.

[0016] In one technical solution, the actuator arm has a split structure, including a first segment and a second segment, which are detachably connected.

[0017] In one technical solution, the end of the actuator arm used to mount the pressure head has a stepped structure, and the stepped structure is located on the side of the actuator arm facing away from the base plate. The stepped surface of the stepped structure has a pressure head mounting hole, and a pressure head mounting screw connected to the pressure head is inserted into the pressure head mounting hole. The head of the pressure head mounting screw is located in the notch structure formed by the stepped structure.

[0018] In one technical solution, the clamping mechanism includes a clamping mounting base and a drive cylinder. The clamping mounting base is mounted on the base plate, and the drive cylinder is mounted on the clamping mounting base to output the clamping force of the flat workpiece.

[0019] The beneficial effects of this utility model are as follows:

[0020] When using the flat workpiece clamping device of this utility model to clamp a flat workpiece, the back of the flat workpiece is supported by the support heads of the support components. Since the support heads are floatingly mounted on the support mounting base, if the back of the flat workpiece is uneven, each support head can be compressed downwards to adapt to the height change of the back of the flat workpiece, achieving multi-point contact support for the uneven back of the flat workpiece. Then, the position of the support heads can be locked by the locking mechanism, and the flat workpiece can be pressed by the clamping mechanism. During the clamping process, the flat workpiece will not be elastically deformed. Therefore, after the clamping force is removed after processing, the flat workpiece will not spring back, ensuring the processing accuracy of the flat workpiece. Since the locking mechanism of each set of support components is mounted on the support mounting base, and the locking mechanism has an operating part, that is, there is no direct installation relationship between the locking mechanism and the base plate. Furthermore, based on the multiple mounting holes of the support components, the installation position of each support component on the base plate is adjustable. Therefore, when it is necessary to clamp flat workpieces of different sizes or shapes, the position of the support components can be adjusted to enable the flat workpiece clamping device to clamp flat workpieces of different sizes or shapes.

[0033] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art.

[0035] In this utility model, a support assembly and a clamping mechanism are installed on the base plate of the flat workpiece clamping device. The support heads of the support assembly are mounted on the support mounting base in a floating manner. When a flat workpiece is placed on the flat workpiece clamping device, the back of the flat workpiece presses down on the support heads, so that each support head can be pressed into the corresponding position according to the shape of the back of the flat workpiece. After the flat workpiece is placed on the support assembly, the position of the support heads is locked by the locking mechanism, and then the clamping mechanism is used to press the flat workpiece on the support assembly. The clamping process will not cause elastic deformation of the flat workpiece. Moreover, the installation position of each set of support assemblies on the base plate can be adjusted. Therefore, for flat workpieces of different sizes or shapes, the position of the support assemblies can be adjusted to meet the clamping requirements of flat workpieces of different sizes or shapes.

[0036] An embodiment of the flat workpiece clamping device of this utility model:

[0037] The flat workpiece clamping device is installed on the worktable of the processing equipment during use. In some embodiments, please refer to... Figure 1 The flat workpiece clamping device includes a base plate 1, a support assembly 2 and a clamping mechanism 3 mounted on the base plate 1.

[0038] The base plate 1 is a rectangular flat plate, though it can also be cubic. Mounting slots 11 are provided at both ends along its length. In use, the base plate 1 engages with the mounting structure on the worktable of the processing equipment via the mounting slots 11, allowing the base plate 1 to be mounted on the worktable, thus enabling the mounting of the flat workpiece clamping device on the worktable. In other embodiments, the shape of the base plate can be changed, such as being a circular plate. The structure for mounting the base plate on the worktable can be any existing structure capable of achieving this function, such as using a pressure plate to press the edges of the base plate onto the worktable; a rectangular shape is preferred here.

[0039] Please refer to Figure 2 and Figure 3 The support assembly 2 includes a support mounting base 21, a support head 22, and a tightening screw 23. The structure of the support mounting base 21 is as follows: Figure 3As shown, the support mounting base 21 includes a cylindrical body 211 with a cylindrical bottom, the cylindrical body 211 having an inner cavity 212, and the support mounting base 21 also includes a flange structure 213 located at the bottom outer side of the cylindrical body 211, the flange structure 213 having a first mounting hole 214. A locking hole 215 penetrating the cylindrical body 211 is also provided on the cylindrical wall, the locking hole 215 being a threaded hole. A tightening screw 23 is installed in the locking hole 215.

[0040] Please refer to Figure 4 The support head 22 includes a cylindrical section 221 and a head 222. The support head 22 is inserted into the inner cavity 212 of the support mounting base 21, and an elastic element is press-fitted between the bottom of the support head 22 and the bottom of the cylindrical base 21. In this way, the support head 22 can be floated on the support mounting base 21 in the vertical direction. The outer peripheral surface of the support head 22 and the inner wall surface of the cylindrical body 211 form a guide structure to guide the movement of the support head 22.

[0041] To lock the position of the support head 22, the support head 22 also includes a locking groove 223 located on the side wall of the cylindrical section 221. The tightening screw 23 constitutes a locking mechanism. When it is necessary to lock the position of the support head 22, the tightening screw 23 can be screwed toward the support head 22, and the tightening screw 23 will press against the bottom of the locking groove 223 to lock the position of the support head 22. The end of the tightening screw 23 away from the support head 22 protrudes from the cylinder 211, forming an operating part for human operation.

[0042] The elastic element can be any suitable elastic element such as a disc spring, compression spring, or rubber block, as long as it can provide a restoring elastic force for the support head 22 when it is pressed down.

[0043] In other embodiments, the locking groove may not be provided on the support head. In this case, the position of the support head is locked by tightening the side wall of the support head with a tightening screw. Of course, the locking mechanism can also be a clamp-type locking mechanism similar to a clamping brake structure, provided at the opening of the inner cavity 212 of the cylinder 211. The clamp-type locking mechanism includes a clamp composed of two half-rings. One half-ring is fixed to the mounting base, and the other half-ring is hinged to the half-ring fixed to the mounting base. When it is necessary to lock the position of the support head, the two half-rings are locked together, and the position of the support head is locked by the two half-rings clamping the support head. As those skilled in the art can know and implement, the locking mechanism can also be any other structure in the prior art that can be used to lock the position of the support head.

[0044] Regarding the structure of the support mounting base, in other embodiments, the support mounting base 21 can also be of other structural forms, such as a rectangular block structure with an inner cavity, a frustum structure, etc. Of course, the support mounting base can also be a column. In this case, the support head is a sleeve-type structure, with the sleeve-type support head fitted onto the column-type support mounting base, and the elastic element disposed within the cavity of the support head. Alternatively, the support mounting base can be a dovetail-shaped slide rail vertically mounted on a base. The support head is mounted on the support mounting base of the dovetail-shaped slide rail via a dovetail groove, and the elastic element is a tension spring with its two ends connected to the support head and the support mounting base respectively. When the support head is compressed and moves downwards, the tension spring is stretched and stores energy.

[0045] Please refer to Figure 5 The clamping mechanism 3 includes a clamping mounting base 31 and a driving device 32. During assembly, the clamping mounting base 31 is mounted on the base plate 1, and the driving device 32 is mounted on the clamping mounting base 31. The driving device 32 has a movable actuating arm 33 capable of outputting driving force. A pressure head 34 is detachably mounted on the actuating arm 33. During operation, the clamping mechanism 3 clamps the flat workpiece onto the support assembly 2 through the pressure head 34. In some embodiments, the pressure head 34 is a cuboid block structure. As those skilled in the art will understand, in other embodiments, the shape of the pressure head can be adapted to meet the usage requirements, such as being disc-shaped.

[0046] In some embodiments, the pressure head 34 is detachably mounted on the actuator arm 33 by a pressure head mounting screw 35. Specifically, the actuator arm 33 has a pressure head mounting hole, which is a through hole. The pressure head 34 has a fixing hole, which is a threaded hole. The pressure head 34 is fixed to the actuator arm 33 by inserting the pressure head mounting screw 35 into the pressure head mounting hole and tightening it with the fixing hole. Since the pressure head is mounted using a single pressure head mounting screw 35, loosening the pressure head mounting screw 35 allows the pressure head 34 to rotate and adjust its position around the pressure head mounting screw 35 as a pivot.

[0047] Please refer to Figure 5 The end of the actuator arm 33 for mounting the pressure head 34 has a stepped structure 36, and the stepped structure is located on the side of the actuator arm 33 facing away from the base plate 1. The pressure head mounting hole for mounting the pressure head 34 is set on the stepped structure 36, and the bolt head of the pressure head mounting screw 35 is located in the notch structure formed by the stepped structure 36, thus making the structure of the clamping mechanism more compact.

[0048] In some embodiments, the actuator arm 33 is a split structure, comprising a first segment 331 and a second segment 332. The first segment 331 and the second segment 332 are detachably connected. Specifically, the end of the first segment 331 is a threaded section with external threads, and the end of the second segment 332 facing the first segment 331 has a threaded hole. The detachable connection between the first segment 331 and the second segment 332 is achieved by screwing the threaded section into the threaded hole. The pressure head 34 is mounted on the second segment 332. Thus, if the connection structure between the pressure head 34 and the actuator arm 33 is damaged and difficult to disassemble, the pressure head 34 can be removed and replaced by disassembling the first segment 331 and the second segment 332. The distinction between the first and second segments here is merely for differentiation; the segment with the threaded section can also be the second segment, and the segment with the threaded hole can also be the first segment.

[0049] The structure of the clamping mounting base 31 is as follows Figure 6 As shown, the system includes two spaced-apart uprights 311 and a top plate 312 connected to the same end of the two uprights 311. The base 31 is fixed to the base plate 1 via the ends of the two uprights 311 away from the top plate 312. A drive device 32 is disposed within the space enclosed by the top plate 312 and the two uprights 311, and the drive device 32 is mounted on the top plate 312 with screws. In other embodiments, the base may also have three or more spaced-apart uprights.

[0050] In some embodiments, the drive device 32 is specifically a pneumatic cylinder; in other embodiments, the drive device 32 may also be a hydraulic cylinder or an electric cylinder. Of course, the drive device may also be a motor, with a motion conversion mechanism, such as a rack and pinion mechanism or a screw and nut mechanism, provided between the motor and the actuator arm to convert the rotational motion output by the motor into linear motion. Regarding the structure of the base, in other embodiments, it may also be other structural forms, such as a cylindrical structure, with the drive device disposed within the cavity of the cylindrical structure.

[0051] In order to be applicable to clamping flat workpieces of different shapes, in some embodiments, the base plate 1 has multiple structures for mounting the support mounting base 21 and the clamping mounting base 31, so that the mounting positions of the support assembly 2 and the clamping mechanism 3 on the base plate 1 are adjustable.

[0052] In some embodiments, the first mounting hole 214 on the support mounting base 21 is a light hole; please refer to... Figure 2Multiple hole structures 12 are arranged in a rectangular array on the base plate 1. Some of the hole structures 12 are threaded holes, which are mounting holes for the support components. Four first mounting holes 214 are provided on the flange structure 213 of the support mounting base 21 at 90° intervals around the central axis of the support mounting base 21. The distance between adjacent support component mounting holes on the base plate 1 is equal to the distance between the first mounting holes 214 on the flange structure 213. By inserting support component mounting screws into the first mounting holes 214 and tightening them, the support mounting base 21 can be mounted on the base plate 1.

[0053] The support components have multiple mounting holes, allowing the position of each set of support components 2 to be adjusted. Furthermore, the head 222 of the support head 22 has a round head structure, which minimizes the support contact area between the support head 22 and the flat workpiece. When adjusting the position of the support components 2, the position change of the part of the support head 22 that contacts the flat workpiece is greater, and the position adjustment is more obvious.

[0054] Please refer to Figure 7 The two upright plates 311 of the base 31 have a second mounting hole 313 at one end that mates with the base plate 1. The second mounting hole 313 is a threaded hole, and some hole structures 12 are through holes. The through holes are mounting holes for the clamping mechanism. The distance between the second mounting holes 313 on the same upright plate 311 is equal to the distance between two adjacent clamping mechanism mounting holes on the base plate 1. By inserting a clamping mechanism mounting screw into the clamping mechanism mounting hole from the side of the base plate 1 facing away from the clamping mechanism 3 and tightening it into the second mounting hole 313, the clamping mounting base 31 can be mounted on the base plate 1. There are multiple clamping mechanism mounting holes, which allows the mounting position of each clamping mechanism 3 to be adjusted. To ensure the flatness of the back side of the base plate 1, the clamping mechanism mounting holes are countersunk holes, so that the head of the clamping mechanism mounting screw can be recessed into the clamping mechanism mounting hole.

[0055] In other embodiments, the mounting holes for the clamping mechanism on the base plate can be smooth holes, and correspondingly, the first mounting hole on the flange structure is a threaded hole. Regarding the mounting method of the clamping mechanism, in other embodiments, the end of the upright plate of the clamping mounting base may have a folded edge, on which a second mounting hole aligned with the mounting hole for the clamping mechanism is opened. The clamping mechanism is mounted on the base plate by setting a clamping mechanism mounting screw in the second mounting hole.

[0056] The mounting structures of the support assembly and the clamping mechanism on the base plate can also be the same. Specifically, the first mounting hole on the support assembly and the second mounting hole on the clamping mechanism are threaded holes of the same size, and the distance between two adjacent first mounting holes on the support assembly is the same as the distance between two adjacent second mounting holes on the same vertical plate. The hole structure on the base plate is a rectangular array of light holes, and the distance between two adjacent light holes is the same as the distance between two adjacent first mounting holes and also the distance between two adjacent second mounting holes on the same vertical plate. Screws are inserted through the back side of the base plate and tightened into the first and second mounting holes to install the support assembly and the clamping mechanism on the base plate. Each light hole is a countersunk hole, so that the head of the screw can be recessed into the light hole, ensuring the flatness of the back side of the base plate.

[0057] In some other embodiments, the support mounting base and the clamping mounting base can also be mounted on the base plate by other structural forms of mounting structure, such as mounting the support mounting base on the base plate by a flange structure of clamping the mounting base with a clamping strip. For the clamping mounting base, a folded edge can also be provided at the end of its upright plate, and the clamping mounting base can be mounted on the base plate by clamping the folded edge with a clamping strip.

[0058] Regarding the number of support components 2 and clamping mechanisms 3, in some embodiments, the flat workpiece clamping device includes three sets of support components 2 and three sets of clamping mechanisms 3. In other embodiments, the number of support components 2 and clamping mechanisms 3 may be unequal. The number of support components 2 may be more than three sets, such as four or five sets, or less than three sets, such as two sets. Regarding the number of clamping mechanisms 3, as those skilled in the art will know, to meet the usage requirements, there may be more than three sets, such as four or five sets, or less than three sets, such as only two sets of clamping mechanisms.

[0059] Taking the milling of the upper side of a flat workpiece as an example, when using the flat workpiece clamping device of this utility model, after the flat workpiece clamping device is installed on the worktable of the processing equipment, the flat workpiece is placed on the support component 2. The bottom surface of the flat workpiece will press down on each support head 22, so that each support component 2 can adapt to the change in the height of the bottom surface of the flat workpiece and change its height. After the flat workpiece is placed, tighten the top screw 23 to lock the position of the support head 22, so as to achieve stable support for the flat workpiece. Then, the pressing mechanism 3 presses the flat workpiece.

[0060] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
