Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibration processing technology, and in particular to a clamping device for workpieces subjected to vibration. Background Technology
[0002] Currently, in vibration processing technology, such as sheet metal edge grinding, a pressure beam is used to clamp the sheet metal during the grinding process. However, the height of the pressure beam is only suitable for pressing sheets of the same thickness. When changing to sheets of different thicknesses, the height of the pressure beam needs to be manually adjusted to match the thickness of the sheet being ground, resulting in low work efficiency. More importantly, by using a fixed pressure beam, the vibration experienced by the sheet metal during edge grinding is directly transmitted through the pressure beam to the adjusting screws of its support frame. This can easily cause the adjusting screws to loosen, leading to a decrease in the height of the pressure beam and potentially causing the sheet metal to crack. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model according to the specific circumstances.
[0029] The following is combined with Figures 1 to 3 This invention describes a clamping device for workpieces subjected to vibration operation, according to an embodiment of the present invention.
[0030] A clamping device for vibrating workpieces includes a drive mechanism 1, a clamping arm 2, and a clamping beam 3. The drive mechanism 1 is mounted and fixed above the worktable. One end of the clamping arm 2 is hinged to the rear end of the drive mechanism 1, and the other end of the clamping arm 2 is hinged to the drive end of the drive mechanism 1. The other end of the clamping arm 2 is also hinged to the clamping beam 3.
[0031] The drive mechanism 1 drives the clamping arm 2 to swing up and down with the rear hinge point as the fulcrum; when the clamping arm 2 swings down, the pressure beam 3 applies pressure to the vibrating workpiece 4.
[0032] The drive mechanism 1 is equipped with an adjustment component 125. The drive mechanism 1 is electrically connected to the pressing height detection system. The drive mechanism 1 adjusts the adjustment component 125 according to the detection result of the pressing height detection system to control the downward swing stroke of the pressing arm 2.
[0033] In a preferred embodiment of the clamping device for workpieces subjected to vibration, this utility model provides an example, such as... Figures 1 to 3 As shown, the clamping device consists of a drive mechanism 1, a clamping arm 2, and a clamping beam 3, which realizes automatic clamping of the vibrating workpiece 4, reducing labor costs and improving work efficiency. The drive mechanism 1 is mounted and fixed above the worktable. One end of the clamping arm 2 is hinged to the rear end of the drive mechanism 1, and the other end of the clamping arm 2 is hinged to the drive end of the drive mechanism 1. The other end of the clamping arm 2 is also hinged to the clamping beam 3, so that the drive mechanism 1 drives the clamping arm 2 to swing up and down around the rear hinge point. When the clamping arm 2 swings down, the clamping beam 3 applies pressure to the vibrating workpiece 4 to achieve clamping. At the same time, the vibration force on the vibrating workpiece 4 can be dispersed through the multiple hinge points of the clamping arm 2. Because it is a drive clamping device (rather than a fixed mechanical structure clamping device), it is less affected by the vibration force. Therefore, the entire clamping device is basically unaffected by the vibration force and is more suitable for clamping workpieces in vibrating operations.
[0034] More importantly, the drive mechanism 1 can detect the height of the vibrating workpiece 4 (if the vibrating workpiece 4 is a sheet material, the height is the thickness of the sheet material) through the clamping height detection system. Based on the detection result, the adjustment component 125 is adjusted to control the downward swing stroke of the clamping arm 2, automatically adapting to different heights of the vibrating workpiece 4, avoiding excessive pressure on the vibrating workpiece 4, and eliminating the need for manual adjustment, thus improving the degree of automation. At the same time, the drive mechanism 1 can also detect whether the workpiece has been delivered to the correct position through the workpiece arrival detection system, and determine when the clamping arm 2 should press down (the clamping arm 2 remains raised when no workpiece is detected), avoiding collision between the pressure beam 3 and the sheet material, thereby realizing a fully automatic clamping process.
[0035] Furthermore, the drive mechanism 1 includes a drive bracket 11 and a drive unit 12; the middle part of the drive bracket 11 is fixed to the fixed bracket 5 above the worktable, the rear end of the drive bracket 11 is hinged to one end of the clamping arm 2, the drive unit 12 is installed at the front end of the drive bracket 11, the drive rod 121 of the drive unit 12 is hinged to the other end of the clamping arm 2, and the extension and retraction movement of the drive rod 121 causes the other end of the clamping arm 2 to swing up and down.
[0036] The drive unit 12 is equipped with an adjustment component 125. The drive unit 12 is electrically connected to the pressing height detection system. The drive unit 12 adjusts the adjustment component 125 according to the detection result of the pressing height detection system to control the extension stroke of the drive rod 121.
[0037] In this embodiment, the drive mechanism 1 is mounted and fixed above the workbench via the drive bracket 11. Since the other end of the clamping arm 2 needs to be driven to apply pressure, the drive unit 12 is installed at the front end of the drive bracket 11, and the drive rod 121 of the drive unit 12 (such as a cylinder, electric cylinder, etc.) is hinged to the other end of the clamping arm 2. Then, the rear end of the drive bracket 11 and one end of the clamping arm 2 are hinged as a rotation point, so that the clamping arm 2 can apply downward pressure around the rotation point when the drive rod 121 is extended.
[0038] Furthermore, the drive unit 12 includes a power cylinder 122, a power cylinder bracket 123, and a control component 124; the piston rod at the bottom end of the power cylinder 122 serves as a drive rod 121; the top of the power cylinder 122 is fixedly connected to the bottom of the power cylinder bracket 123; the control component 124 is fixedly connected to the top of the power cylinder bracket 123; the adjustment component 125 is disposed on the top of the power cylinder 122; the drive end of the adjustment component 125 and the bottom of the control component 124 is movably connected in the middle of the power cylinder bracket 123; and the power cylinder bracket 123 is mounted on the front end of the drive bracket 11.
[0039] In this embodiment, the drive unit 12 preferably consists of a power cylinder 122, a power cylinder bracket 123, and a control component 124. The power cylinder 122 is responsible for driving, and the control component 124 is responsible for control. The power cylinder bracket 123 is responsible for mounting the power cylinder 122 and the control component 124 on the front end of the drive bracket 11, so that the adjustment component 125 at the top of the power cylinder 122 can adjust the driving end (such as a planetary reducer under servo motor control) at the bottom of the control component 124 and the moving distance of the adjustment component 125 according to the required descent height detected by the pressing height detection system, thereby realizing pressure control.
[0040] Furthermore, the adjustment assembly 125 includes a limit adjustment nut 1251, a limit adjustment sleeve 1252, and a pressure beam lifting sensing sleeve 1253; the power rod at the top of the power cylinder 122 passes through the limit adjustment nut 1251, the top end of the limit adjustment sleeve 1252 is movably sleeved on the drive end at the bottom of the control assembly 124, the bottom of the limit adjustment sleeve 1252 and the top of the limit adjustment nut 1251 are movably connected, the power rod at the top of the power cylinder 122 moves through the adjustment hole of the limit adjustment nut 1251, and the pressure beam lifting sensing sleeve 1253 is set on the top of the power cylinder 122 and sleeved on the outer periphery of the limit adjustment nut 1251;
[0041] The shorter the distance between the top of the limit adjusting nut 1251 and the top of the limit adjusting sleeve 1252, the shorter the extension stroke of the drive rod 121; the longer the distance between the top of the limit adjusting nut 1251 and the top of the limit adjusting sleeve 1252, the longer the extension stroke of the drive rod 121.
[0042] In this embodiment, to control the distance between the drive end at the bottom of the adjustment control component 124 and the moving distance of the adjustment component 125, the adjustment component 125 is composed of a limit adjustment nut 1251, a limit adjustment sleeve 1252, and a pressure beam lifting sensing sleeve 1253. The power cylinder 122 adjusts the limit adjustment nut 1251 up and down by electric adjustment, so that the distance between it and the top of the limit adjustment sleeve 1252 is shortened or extended, thereby matching the detected workpiece height and controlling the extension stroke of the drive rod 121 (piston rod) of the power cylinder 122 (the power cylinder 122 also senses the stroke through the pressure beam lifting sensing sleeve 1253), thereby realizing automatic adaptation of the clamping degree according to the workpiece height.
[0043] Furthermore, the bottom surface of the pressure beam 3 and the vibrating workpiece 4 make sliding contact.
[0044] In this embodiment, when the vibration intensity is too high, it will still affect the normal operation of the clamping device. Therefore, the bottom surface of the pressure beam 3 and the vibrating workpiece 4 are preferably in sliding contact. When the vibration intensity is not high, the workpiece can be clamped by the pressure applied by the drive mechanism 1. When the vibration intensity is too high, the bottom surface of the pressure beam 3 and the vibrating workpiece 4 can slide relative to each other to alleviate the vibration amplitude, reduce the vibration force on the clamping device, and ensure the normal operation of the clamping device.
[0045] Furthermore, a connecting rod 111 is provided at the rear end of the drive bracket 11, and the bottom end of the connecting rod 111 is hinged to one end of the clamping arm 2.
[0046] In this embodiment, in order to reduce the transmission of vibration force to the drive bracket 11, which could cause the screws in the drive bracket 11 and the fixed bracket 5 above the worktable to loosen, it is preferable to set a connecting rod 111 downward at the rear end of the drive bracket 11. Then, after the height is reduced by the connecting rod 111, it is hinged to one end of the clamping arm 2, thereby changing the direction of force and reducing the vibration force on the drive bracket 11 and the fixed bracket 5.
[0047] Furthermore, the left and right side brackets in the middle of the power cylinder bracket 123 are hinged to the front end of the drive bracket 11, respectively.
[0048] In this embodiment, in order to increase the flexibility of the power cylinder 122 in applying pressure through the piston rod of the drive rod 121 and the accuracy of the pressure direction, it is preferable to install the power cylinder bracket 123 by hinged connection between the left and right side frames in the middle of the power cylinder bracket 123 and the front end of the drive bracket 11, so that the power cylinder bracket 123 can rotate as the other end of the clamping arm 2 is pressed and rotated, thereby adjusting the pressure direction of the power cylinder 122.
[0049] Furthermore, a position switch 1221 is provided on the periphery of the power cylinder 122, and a position sensing block 1211 is sleeved on the drive rod 121. The position switch 1221 is used to sense the position sensing block 1211.
[0050] In this embodiment, some power cylinders 122 are equipped with a protection mechanism. Before applying pressure, the piston rod of the power cylinder 122 needs to be retracted to the correct position before the adjustment component 125 on the top of the power cylinder 122 can be adjusted to change the pressing stroke. This ensures the stability of the operation of the power cylinder 122, such as stable air pressure and accurate stroke. Therefore, a position switch 1221 is provided on the periphery of the power cylinder 122 to sense the position sensing block 1211 sleeved on the drive rod 121. When the drive rod 121 is retracted to the correct position, the adjustment component 125 is activated for adjustment.
[0051] Furthermore, the other end of the clamping arm 2 is hinged to a plug-in round rod 21, and the drive rod 121 is plugged and fixed in the plug-in interface of the plug-in round rod 21, and the position sensing block 1211 abuts against the plug-in interface of the plug-in round rod 21.
[0052] In this embodiment, in order to hinge the other end of the clamping arm 2 to the drive rod 121, a plug-in round rod 21 is first hinged to the other end of the clamping arm 2. The drive rod 121 is fixed inside the plug-in round rod 21 through the plug-in interface of the plug-in round rod 21 to form a fixed relationship. At the same time, after the position sensing block 1211 is sleeved on the drive rod 121, it abuts against the plug-in interface of the plug-in round rod 21, which can limit the position sensing block 1211 and ensure the accuracy of the drive rod 121 retracting into place.
[0053] Furthermore, the pressure beam 3 includes a pressure beam member 31 and at least one pulley 32; the top of the pressure beam member 31 and the other end of the pressure arm 2 are hinged, and the pulleys 32 are arranged from front to back on the bottom surface of the pressure beam member 31, and the pulleys 32 are used to apply pressure to the vibrating workpiece 4.
[0054] In this embodiment, the sliding contact relationship between the bottom surface of the pressure beam 3 and the vibrating workpiece 4 is preferably achieved by arranging pulleys 32 from front to back on the bottom surface of the pressure beam 31.
