[0002] The clamping force detection device for the fixture is mainly used to detect the clamping force of the fixture during the clamping process, ensuring that the clamping performance of the fixture meets the design requirements and production standards. This device, through a high-precision pressure sensor and drive system, can simulate actual use scenarios and accurately measure the magnitude of the force generated by the fixture during the clamping process.

[0003] When testing the clamping force of a fixture, a mounting post is typically installed on the fixture base, and a pressure sensor is mounted on the mounting post. The fixture clamps the mounting post, allowing the pressure sensor to detect the clamping force value, thus completing the clamping force test. However, in actual use, because the clamping plates of the fixture are replaceable, allowing it to clamp workpieces of different sizes, the mounting post needs to be disassembled and replaced when testing the clamping force of fixtures with different clamping plates. This results in frequent disassembly and assembly of the mounting post on the fixture base. Since the mounting post is generally installed on the fixture base using bolts or other fasteners, the disassembly and assembly process is quite cumbersome and needs improvement.

[0033] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0034] The following is in conjunction with the appendix Figures 1-8 This embodiment will be described in further detail.

[0035] Combined with appendix Figures 1-8 The clamping force detection device of the clamp in this embodiment includes a base 100, a clamping seat 103 on the upper side of the base 100; a support column 101 is provided at the four corners of the upper side of the base 100, a top platform 102 is provided between the upper ends of the multiple support columns 101, a cavity is provided in the top platform 102, a sliding groove communicating with the cavity is provided on the lower side of the top platform 102 along its length direction, and a clamping assembly is provided on the lower side of the top platform 102.

[0036] The clamping assembly includes a movable plate 104 disposed on the top platform 102. The movable plate 104 is L-shaped. The upper end of the movable plate 104 extends into the cavity through a slide groove. A clamping plate 107 is fixedly provided at the lower end. A rotatable lead screw 800 is provided in the cavity along its length direction. The extension end of the movable plate 104 is threaded onto the lead screw 800.

[0037] The upper side of the clamp 103 and the center position are provided with an insertion groove 306 with an upper opening along its height direction. The insertion groove 306 is provided with a pluggable mounting post 105. A detection component is press-fitted onto the mounting post 105 by a press-fitting component. The detection component includes a pressure sensor 201.

[0038] The clamp 103 has a cavity 303 with opposite sides, and a locking component is provided in the cavity 303. The mounting post 105 has a corresponding locking hole 202. The locking component is inserted into the corresponding locking hole 202 to fix the mounting post 105 on the clamp 103. The clamp 103 also has an unlocking component to release the locking component from fixing the mounting post 105.

[0039] In actual use, the pressure sensor 201 is pressed onto the mounting post 105 using a press-fitting component, so that the pressure sensor 201 can be installed on the mounting post 105. The mounting post 105 is inserted into the insertion slot 306, and the locking component is inserted into the corresponding locking hole 202, so that the mounting post 105 can be fixed in the insertion slot 306, thus enabling the mounting post 105 to be installed on the clamp 103.

[0040] Combination Figure 8 As shown, in actual use, the lead screw 800 has symmetrical and opposite threads. A motor 801 is installed in the cavity through a mounting bracket. The output end of the motor 801 passes through the mounting bracket and is connected to one end of the lead screw 800, so that the motor 801 can drive the lead screw 800 to rotate. Since the slide groove is adapted to the moving plate 104, the slide groove can limit the moving plate 104, so that the rotation of the lead screw 800 can drive the two moving plates 104 to move closer or further away from each other, so that the two moving plates 104 can drive the corresponding clamping plates 107 to move closer to each other to clamp the mounting column 105. Specifically, the pressure sensor 201 corresponds to the clamping plate 107, so that when the clamping plate 107 clamps the mounting column 105, the clamping plate 107 can clamp the pressure sensor 201, so that the pressure sensor 201 can detect the clamping force generated when the two clamping plates 107 clamp.

[0041] Specifically, the detection components also include a processor and a display screen. The pressure sensor 201 is electrically connected to the processor, and the processor is electrically connected to the display screen, so that the data detected by the pressure sensor 201 can be transmitted to the processor, and after processing by the processor, the specific values ​​are displayed on the display screen for the operator to view.

[0042] When it is necessary to remove the mounting post 105 from the clamp 103, the unlocking component is designed to drive the locking component to disengage from the corresponding lock hole 202, thereby releasing the fixed installation of the mounting post 105 on the clamp 103. At this time, the operator holds the mounting post 105 and pulls it out of the insertion slot 306, thus completing the removal of the mounting post 105 from the clamp 103.

[0043] Combination Figures 2-3 As shown, the cavity 303 is located on both sides of the insertion slot 306 and is connected to the insertion slot 306. The lower end of the mounting post 105 is provided with an insertion block 203, and the side wall opposite to the insertion block 203 is provided with a first inclined surface 204.

[0044] The locking assembly includes a fixed rod 301 arranged along the length of the cavity 303, a locking block 304 slidably arranged on the fixed rod 301, and a second inclined surface 600 adapted to the first inclined surface 204 at one end of the locking block 304 facing the insertion groove 306; the fixed rod 301 is also provided with a first spring 302, which is used to push the locking block 304 into the corresponding lock hole 202.

[0045] In practical use, the plug-in block 203 is fixedly installed at the lower end of the mounting post 105. When the mounting post 105 needs to be fixedly installed on the clamp 103, the plug-in block 203 is aligned with the plug-in groove 306 and inserted into the plug-in groove 306, so that the two first inclined surfaces 204 on the plug-in block 203 can slide and fit against the corresponding second inclined surface 600. At this time, the mounting post 105 is moved down further, so that the first inclined surface 204 can slide and press against the corresponding second inclined surface 600, so that the second inclined surface 600 can drive the corresponding locking block 304 to interact. The first spring 302 is moved away from and compressed, and the rod retracts into the cavity 303. At this time, the mounting post 105 continues to move downward. When the lower side of the plug block 203 abuts against the bottom wall of the plug groove 306, the two locking holes 202 can be aligned with the corresponding locking blocks 304. Under the action of the first spring 302, the two first springs 302 can push the corresponding locking blocks 304 into the corresponding locking holes 202, so that the mounting post 105 cannot be dislodged from the plug groove 306, thereby allowing the mounting post 105 to be fixedly installed on the clamp 103.

[0046] In actual use, the locking block 304 has a cavity along its length. One end of the fixing rod 301 is inserted into the cavity, and an abutment plate 305 is fixed at the inserted end. Through the setting of the fixing rod 301 and the abutment plate 305, the locking block 304 can slide along the fixing rod 301. When the abutment plate 305 abuts against one side wall of the cavity, the locking block 304 stops sliding, thereby preventing the locking block 304 from sliding out of the corresponding cavity 303.

[0047] One end of the fixing rod 301 is fixedly installed on the corresponding side wall of the cavity 303. A rubber pad is provided on the corresponding side wall of the cavity 303. A rubber pad is also provided on the side wall of the locking block 304 facing the cavity 303. The two ends of the first spring 302 abut against the corresponding rubber pads. By setting the rubber pads, the first spring 302 can be better prevented from moving on the fixing rod 301.

[0048] The plug block 203 is adapted to the plug slot 306, so that the plug block 203 is not easy to move in the plug slot 306, thereby enabling the locking block 304 to be aligned with the lock hole 202.

[0049] The lock hole 202 is adapted to the lock block 304, so that the lock block 304 will not move within the lock hole 202, thereby allowing the mounting post 105 to be better fixed within the insertion groove 306.

[0050] Combination Figures 4-6As shown, in this embodiment, the clamp 103 is provided with a mounting cavity 406, and the side wall of the mounting cavity 406 is provided with a communicating groove 500 that communicates with the corresponding cavity 303. The unlocking component includes a connecting plate 400 provided on the side wall of the corresponding lock block 304. The connecting plate 400 is L-shaped, and one end of the connecting plate 400 extends into the mounting cavity 406 through the communicating groove 500. The end of the connecting plate 400 extending into the cavity is provided with a third inclined surface. The unlocking component also includes a driving member provided in the mounting cavity 406. The driving member is used to drive the two connecting plates 400 to move the corresponding lock blocks 304 away from each other and disengage from the corresponding lock holes 202.

[0051] In this embodiment, the driving component includes a driving block 401. A fourth inclined surface 602 adapted to the third inclined surface is provided on the opposite side wall of the driving block 401. A driving rod 404 is provided on the side wall of the driving block 401. One end of the driving rod 404 extends out of the clamping seat 103 through the mounting cavity 406. A second spring 403 is also sleeved on the driving rod 404. The second spring 403 is used to push the driving block 401 to reset. A T-shaped limiting groove 402 is provided on the bottom wall of the mounting cavity 406 along its width direction. A limiting block 601 extending into the limiting groove 402 is provided on the lower side wall of the driving block 401.

[0052] In actual use, when the locking block 304 is inserted into the corresponding lock hole 202, the two locking blocks 304 can drive the corresponding connecting plate 400 to move along the connecting groove 500, thereby allowing the connecting plate 400 to drive the third inclined surface to fit against the fourth inclined surface 602. When it is necessary to release the fixed installation of the mounting post 105 on the clamp 103, by pulling the drive rod 404 outward, the drive rod 404 can drive the drive block 401 to drive the fourth inclined surface 602 to move along the third inclined surface, thereby allowing the fourth inclined surface 602 to slide and press against the third inclined surface, so that the third inclined surface can drive the connecting plate 400 to drive the corresponding locking block 304 to slide away from the corresponding lock hole 202, thereby releasing the fixed installation of the mounting post 105 on the clamp 103. At this time, the drive rod 404 is released, so that under the action of the second spring 403, the second spring 403 can push the drive block 401 to reset.

[0053] Meanwhile, under the action of the first spring 302, the first spring 302 can drive the third inclined surface to always be in contact with the fourth inclined surface 602. When the driving block 401 is reset, the third inclined surface can slide along the fourth inclined surface 602 and reset, so that the two locking blocks 304 can always be inserted into the insertion slot 306.

[0054] In actual use, through the setting of the limiting groove 402 and the limiting block 601, when the drive rod 404 is pulled outward, the drive rod 404 can drive the drive block 401 to drive the limiting block 601 to move along the limiting groove 402, so that the connecting plate 400 drives the corresponding locking block 304 to slide out of the corresponding lock hole 202. When the limiting block 601 slides against one end of the limiting groove 402, when the drive rod 404 is pulled outward, the drive rod 404 cannot drive the drive block 401 to move along the limiting groove 402. At this time, the third inclined surface is still attached to the fourth inclined surface 602, so as to better prevent the fourth inclined surface 602 from sliding out of the third inclined surface.

[0055] The first end of the connecting plate 400 is fixedly connected to the side wall corresponding to the locking block 304; the drive rod 404 is fixedly installed on the side wall of the drive block 401; and the limiting block 601 is fixedly installed on the lower side of the drive block 401.

[0056] Specifically, a rubber pad is provided on one side wall of the drive block 401, and a rubber pad is provided on the corresponding side wall of the mounting cavity 406. The two ends of the second spring 403 abut against the corresponding rubber pads. By setting the rubber pads, the second spring 403 will not move on the drive rod 404.

[0057] The upper ends of the cavity 303 and the mounting cavity 406 are provided with openings, and a detachable side plate 300 is provided at the opening position by screws. The side plate 300 allows the cavity 303 and the mounting cavity 406 to be opened, thereby facilitating the operator to install the locking and unlocking components.

[0058] In order to facilitate the operator to pull the drive rod 404 outward, in this embodiment, a pull post 405 is fixedly provided at the end of the extended end of the drive rod 404. The pull post 405 facilitates the operator to pull the drive rod 404 outward.

[0059] Combination Figures 2-7 As shown, in this embodiment, the upper end of the mounting post 105 is provided with a mounting groove 700, which is used to install the pressure sensor 201; the pressing component includes an arc plate 702 provided at the upper end of the mounting post 105, and the pressing component also includes a pressing cylinder 106, on which a locking bolt 200 is threaded.

[0060] In actual use, the outer side wall of the pressing cylinder 106 is provided with an arc-shaped pressing groove 701, and the upper side wall of the pressing cylinder 106 is provided with a wiring hole 206.

[0061] In actual use, the lower end of the pressing cylinder 106 is open. The data cable of the pressure sensor 201 is passed through the wiring hole 206 inside the pressing cylinder 106. Then, the pressure sensor 201 is placed in the mounting groove 700. At this time, the pressing groove 701 on the pressing cylinder 106 is aligned with the pressure sensor 201 and covered on the upper side of the mounting post 105, thereby realizing the pressing of the pressure sensor 201 on the mounting post 105. Then, the locking bolt 200 is tightened so that one end of the locking bolt 200 can abut against the arc plate 702, so that the pressing cylinder 106 can be fixedly installed on the mounting post 105.

[0062] The outer wall of the press cylinder 106 is fixedly provided with a threaded cylinder 205, and the locking bolt 200 is threadedly installed in the threaded cylinder 205. By setting the threaded cylinder 205, the pitch of the locking bolt 200 can be increased, thereby increasing the connection strength between the locking bolt 200 and the arc plate 702.

[0063] In practical use, when the mounting post 105 needs to be installed on the clamp 103, the insertion block 203 is aligned with the insertion groove 306 and inserted into the insertion groove 306, so that the two first inclined surfaces 204 on the insertion block 203 can slide and fit against the corresponding second inclined surface 600. At this time, the mounting post 105 is moved down further, so that the first inclined surface 204 can slide and press against the corresponding second inclined surface 600, so that the second inclined surface 600 can drive the corresponding locking block 304 to move away from each other and compress the first spring 302, retracting into the cavity 303, so that the locking block 304 can drive the corresponding connecting plate 400 to move away from each other and disengage from the corresponding fourth inclined surface 602. At this time, the mounting post 105 is driven down further. When the lower side of the insertion block 203 abuts against the bottom wall of the insertion groove 306, the two locking holes 202 can be aligned with the corresponding locking blocks 304, so that under the action of the first spring 302, the two first springs 304 can... 02 can push the corresponding locking block 304 into the corresponding lock hole 202, and at the same time, the locking block 304 can drive the third inclined surface on the corresponding connecting plate 400 to fit against the corresponding fourth inclined surface 602, so that the mounting post 105 can be fixedly installed on the clamp 103; when it is necessary to remove the mounting post 105 from the clamp 103, by pulling the drive rod 404 outward, the drive rod 404 can drive the drive block 401 to drive the fourth inclined surface 602 to move along the third inclined surface, so that the fourth inclined surface 602 can slide and squeeze the third inclined surface, so that the third inclined surface can drive the connecting plate 400 to drive the corresponding locking block 304 to slide away from the corresponding lock hole 202, that is, release the fixed installation of the mounting post 105 on the clamp 103. At this time, the operator holds the mounting post 105 and pulls it out from the insertion slot 306, thus completing the removal of the mounting post 105 from the clamp 103. The removal and installation operation is relatively simple and convenient.

[0064] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
