Description

Technical Field

[0001] The utility model relates to the technical field of electric clamp testing, in particular to a performance testing device for an electric clamp. Background Art

[0002] An electric gripper, also known as an electric clamp, electric gripper or electric claw, is an automated end effector that is driven by a motor to achieve opening and closing actions. Its main function is to simulate human hands to grasp, carry, assemble and other operations on objects. It is widely used in industrial automation production lines, robotic systems, logistics sorting and other fields.

[0003] Taking the electric gripper with two degrees of freedom as an example, this type of electric gripper is usually equipped with two grippers, which move back and forth relative to each other in one direction to clamp or release the clamped part, and rotate in a plane to position the clamped part. In order to ensure the stable performance of the electric gripper, the rotation accuracy and clamping accuracy of the electric gripper need to be strictly tested and verified. When the rotation accuracy is poor, it will cause the positioning error of the clamped part, or even the inability to grasp, affecting the process of the entire automated production line. When the clamping accuracy is low, that is, the clamping force of each batch is inconsistent or the clamping force repeatability is low, the originally set clamping force parameters will not meet the current use environment, and the clamping force will be too large or too small. The clamped part is very likely to fall off due to the small clamping force during the movement, or be damaged by the clamping force due to the large clamping force. Therefore, it is particularly important to test and verify the key parameters of the electric gripper to ensure the consistency and repeatability of the electric gripper to reduce the failure rate of equipment equipped with electric grippers.

[0071] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0072] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0073] The embodiment of the utility model discloses a performance testing device for an electric clamping jaw 01, comprising a clamping fixing seat 11, a clamping finger rotation detection member 12, a main shaft rotation detection member 13 and an information processor.

[0074] As attached Figure 1 and 2As shown, the clamping seat 11 is fixedly arranged to clamp and fix the electric clamp 01, which can ensure that the clamping fingers 011 of the electric clamp 01 can rotate normally with the main shaft during the test, and can ensure that the two clamping fingers 011 open and close normally during the test, and can also ensure that the outer shell of the electric clamp 01 is fixed, avoiding malfunction of the electric clamp 01 during the test and affecting the accuracy of the test results.

[0075] The gripping finger rotation detection member 12 is detachably connected to the first side of the gripping fixed seat 11, and the spindle rotation detection member 13 is detachably connected to the second side of the gripping fixed seat 11, that is, the gripping finger rotation detection member 12 and the spindle rotation detection member 13 are respectively arranged on both sides of the gripping fixed seat 11 to align with different parts of the electric gripper 01. The detachable connection between the gripping finger rotation detection member 12 and the spindle rotation detection member 13 is convenient for replacement and can flexibly adjust the positions of the two detection members to compensate for the assembly error of the electric gripper 01.

[0076] The finger rotation detection member 12 is aligned with the two fingers 011 of the electric gripper 01, and is used to detect the positions of the two fingers 011 of the electric gripper 01 when the electric gripper 01 rotates. The spindle rotation detection member 13 is aligned with the spindle of the electric gripper 01, and is used to detect the position of the spindle of the electric gripper 01 when the electric gripper 01 rotates. The finger rotation detection member 12 and the spindle rotation detection member 13 can be laser displacement sensors, but are not limited thereto, and can also be ultrasonic sensors, etc.

[0077] The information processor is connected to the finger rotation detection member 12 and the spindle rotation detection member 13 respectively, and is used to receive and process the signals sent by the finger rotation detection member 12 and the spindle rotation detection member 13 to test the test accuracy of the electric gripper 01. Of course, the information processor includes a signal receiving unit, a signal judging unit and a signal sending unit. The signal receiving unit is used to receive the position signal sent by the two detection members. The signal judging unit is electrically connected to the signal receiving unit so that the signal judging unit is used to judge whether the signal received by the signal receiving unit is a trigger signal. The signal sending unit is electrically connected to the signal judging unit so that the signal sending unit sends the judgment signal generated by the signal judging unit to an actuator such as an alarm or a display. The specific setting methods of the signal receiving unit, the signal judging unit and the signal sending unit can refer to the prior art; in the present utility model, only the application scenarios of the above three are changed, and no substantial improvement is made thereto. The information processor with this structure is widely used in existing automatic control equipment, such as MCU, DSP or single-chip microcomputer. The key point of the present utility model is that the information processor combines each detection member and each actuator in pairs.

[0078] When the electric gripper 01 rotates, the gripper finger rotation detection component 12 detects the positions of the two gripper fingers 011 of the electric gripper 01, and the spindle rotation detection component 13 detects the spindle position of the electric gripper 01. The gripper finger rotation detection component 12 feeds back the gripper finger 011 position information to the information processor, and the spindle rotation detection component 13 feeds back the spindle position information to the information processor. The information processor receives the feedback signals from the gripper finger rotation detection component 12 and the spindle rotation detection component 13, and determines whether the gripper finger position information and the spindle position information are within the set error range. If so, the rotation accuracy of the electric gripper is qualified, and thus the rotation accuracy of the electric gripper is tested; if not, an alarm instruction is issued;

[0079] By repeatedly measuring the signal fed back by the rotating detection part 12, if the distance measured each time is greatly different, it means that the repeated rotation accuracy of the two clamping fingers 011 of the electric clamp 01 is poor; if the difference is small, it means that the rotation accuracy of the two clamping fingers 011 of the electric clamp 01 is qualified; similarly, by repeatedly measuring the signal fed back by the rotating detection part 13, if the distance measured each time is greatly different, it means that the repeated rotation accuracy of the two clamping fingers 011 of the electric clamp 01 is poor; if the difference is small, it means that the rotation accuracy of the two clamping fingers 011 of the electric clamp 01 is qualified.

[0080] The utility model reasonably arranges the positions of the finger rotation detection member 12 and the spindle rotation detection member 13 relative to the electric clamp 01 , so that the position information obtained is more accurate and the rotation accuracy of the electric clamp 01 can be accurately tested.

[0081] As attached Figures 3 to 7 As shown, the performance testing device of the electric gripper 01 also includes an adjustable bracket 14, which is detachably connected between the gripper finger rotation detection member 12 and the clamping fixed seat 11, and is used to adjust the position of the gripper finger rotation detection member 12 relative to the clamping fixed seat 11, so as to flexibly adjust the position of the gripper finger rotation detection member 12, so that the gripper finger rotation detection member 12 can adapt to electric grippers 01 of different specifications or different installation methods, and has good adaptability.

[0082] The electric gripper 01 can adjust the position of the gripper finger rotation detection member 12 in a single direction, longitudinally, transversely and vertically, to ensure that the gripper finger rotation detection member 12 is aligned with the two gripper fingers 011 of the electric gripper 01, thereby improving the test accuracy. Figure 1 The X-axis direction, the Y-axis direction and the Z-axis direction.

[0083] As attached Fig. 9As shown, the adjustable bracket 14 includes an L-shaped support plate 141, an L-shaped bearing rod 142, an L-shaped connecting rod 143, a longitudinal adjustment component 144, a lateral adjustment component 145 and a vertical adjustment component 146. The bottom end of the L-shaped support plate 141 is fixedly connected to the clamping finger rotation detection member 12, the L-shaped bearing rod 142 is detachably connected to the clamping fixed seat 11, and the L-shaped connecting rod 143 is detachably connected between the L-shaped support plate 141 and the L-shaped bearing rod 142.

[0084] The longitudinal adjustment assembly 144 is disposed between the L-shaped bearing rod 142 and the clamping and fixing seat 11, and is used to adjust the position of the L-shaped bearing rod 142 relative to the clamping and fixing seat 11 in the longitudinal direction. The longitudinal adjustment assembly 144 includes a longitudinal waist-shaped hole disposed on the L-shaped bearing rod 142, a plurality of longitudinal adjustment holes disposed in the longitudinal direction at the bottom end of the right baffle 113 of the clamping and fixing seat 11, and a longitudinal locking member passing through the longitudinal waist-shaped hole and selectively fixedly connected to the longitudinal adjustment hole.

[0085] The transverse adjustment assembly 145 is disposed between the L-shaped bearing rod 142 and the L-shaped connecting rod 143, and is used to adjust the position of the L-shaped connecting rod 143 relative to the L-shaped bearing rod 142 in the transverse direction. The transverse adjustment assembly 145 includes a transverse waist-shaped hole disposed on the L-shaped connecting rod 143, a plurality of transverse adjustment holes disposed in the transverse direction at one end of the L-shaped bearing rod 142 away from the longitudinal waist shape, and a transverse locking member passing through the transverse waist-shaped hole and selectively fixedly connected to the transverse adjustment hole.

[0086] The vertical adjustment assembly 146 is disposed between the L-shaped connecting rod 143 and the L-shaped support plate 141, and is used to adjust the position of the L-shaped support plate 141 relative to the L-shaped connecting rod 143 in the vertical direction. The vertical adjustment assembly 146 includes a vertical waist-shaped hole disposed at one end of the L-shaped connecting rod 143 away from the transverse waist-shaped hole, a plurality of vertical adjustment holes disposed vertically on the L-shaped support plate 141, and a vertical locking member passing through the vertical waist-shaped hole and selectively fixedly connected to the vertical adjustment hole.

[0087] Attached Figure 1 and 2As shown, the performance test device of the electric clamp 01 also includes an adjustment fixing seat 15, which is detachably connected between the spindle rotation detection member 13 and the clamping fixing seat 11, and is used to adjust the position of the spindle rotation detection member 13 relative to the clamping fixing seat 11 in the longitudinal direction, to ensure that the spindle rotation detection member 13 is aligned with the spindle of the electric clamp 01, so that the spindle rotation detection member 13 can adapt to electric clamps 01 of different specifications, and the adaptability of the whole set of testing devices is better. The adjustment fixing seat 15 is specifically L-shaped, and the spindle rotation detection member 13 is fixed at the bottom of the adjustment fixing seat 15. A waist-shaped long strip hole is provided at the bottom of the left baffle 112 of the clamping fixing seat 11, and the adjustment fixing seat 15 is provided with at least one adjustment fixing hole, and a limit locking member is inserted into the waist-shaped long strip hole, and the limit locking member selectively passes through the adjustment fixing hole, so that the adjustment fixing seat 15 is reliably fixed on the clamping fixing seat 11. Of course, the fixing method of the spindle rotation detection member 13 is not limited to this.

[0088] As attached Figure 1 and 2 As shown, the performance test device of the electric clamp 01 also includes a V-shaped support seat 16 with a V-shaped fixing groove 161. The angle of the V-shaped fixing groove 161 is 90 degrees, and it is formed by the intersection of a horizontal support surface and a vertical support surface. The clamping fixing seat 11 is fixed on one side of the V-shaped fixing groove 161, and the clamping fixing seat 11 is specifically fixed on the vertical support surface, so as to simulate the working condition of the electric clamp 01 clamping the clamped object vertically, which is closer to the actual working scene of the clamped object, and the test structure is more accurate.

[0089] As attached Figure 4As shown, the clamping fixing seat 11 includes a U-shaped bottom support plate 111, a left baffle plate 112, a right baffle plate 113, a left top member 114 and a right top member 115. The U-shaped bottom support plate 111 is fixed on one side of the V-shaped fixing groove 161. The U-shaped bottom support plate 111 is used to increase the distance between the electric clamp 01 and the vertical support surface of the V-shaped support seat 16, so that space is reserved between the U-shaped bottom support plate 111 and the V-shaped support seat 16 to prevent the two clamping fingers 011 of the electric clamp 01 from colliding and interfering when rotating or opening and closing. The U-shaped bottom support plate 111 is symmetrically provided with fixed flanges on both sides, which are close to the vertical support surface and are fixed to the V-shaped support seat 16 by fastening screws. The left baffle plate 112 and the right baffle plate 113 are symmetrically fixed on both sides of the U-shaped bottom support plate 111, and a clamping groove is formed between the right baffle plate 113 and the left baffle plate 112. The clamping groove is used to accommodate the electric clamp 01 so that the electric clamp 01 can be fixed vertically. Both the left baffle plate 112 and the right baffle plate 113 can be U-shaped structures to increase strength and avoid bending and deformation and failure to tighten the electric clamp 01. The left side tightening member 114 is fixed on the left side baffle plate 112, and the right side tightening member 115 is fixed on the right side baffle plate 113. The right side tightening member 115 and the left side tightening member 114 cooperate to press and fix the electric clamp 01 in the clamping groove. Both the left side tightening member 114 and the right side tightening member 115 can be conventional clamps, which are convenient for disassembling and assembling the clamp from the clamping groove, making the operation more convenient and conducive to improving the test efficiency. Of course, the structures of the left side tightening member 114 and the right side tightening member 115 are not limited to this.

[0090] As attached Figure 6 As shown, the U-shaped bottom support plate 111 is fixed with at least one positioning pin 1111, which cooperates with the structural hole provided on one side of the electric clamp 01 to limit the position of the electric clamp 01 in the clamping groove, and limits the electric clamp 01 from moving randomly relative to the clamping groove due to factors such as gravity during the clamping process, thereby making the test accuracy more accurate.

[0091] As attached Figures 11 to 15 As shown, the electric clamp 01 includes two clamping blocks 012 and two clamping fingers 011. The two clamping blocks 012 are respectively connected to the two clamping fingers 011. The two clamping blocks 012 serve as driving parts, which are used to drive the two clamping fingers 011 to move respectively, so that the two clamping fingers 011 move closer to each other or separate from each other, thereby making the two clamping fingers 011 close and open accordingly.

[0092] The performance test device of the electric clamp 01 also includes a clamping finger detection member 17 and a clamping block detection member 18. The clamping finger detection member 17 is disposed between the two clamping fingers 011 of the electric clamp 01, and is used to detect the clamping force of the clamping finger 011 between the two clamping fingers 011. The clamping block clamping detection member 18 is disposed between the two clamping blocks 012 of the electric clamp 01, and is used to detect the clamping force of the clamping block 012 between the two clamping blocks 012. In other words, the utility model simultaneously measures the clamping force between the two clamping fingers 011 and the two clamping blocks 012, and by comparing the clamping force of the clamping finger 011 and the clamping force of the clamping block 012, it is possible to accurately test the clamping accuracy of the electric clamp 01. It should be noted that, considering that the clamping finger 011 is mounted on the clamping block 012, the clamping block clamping detection member 18 is detachably arranged, when measuring, the clamping finger 011 is first removed from the clamping block 012, and then the clamping block clamping detection member 18 is mounted between the two clamping blocks 012, so as to accurately test the clamping force of the clamping block 012 between the two clamping blocks 012. Both the clamping finger clamping detection member 17 and the clamping block clamping detection member 18 can be pressure sensors, but are not limited thereto.

[0093] As attached Figure 1 and 2 As shown, a transverse adjustment groove 162 is provided on one side of the V-shaped fixing groove 161 away from the clamping fixing seat 11. The performance testing device of the electric clamp 01 also includes a transverse adjustment seat 19, a longitudinal adjustment plate 20 and an adjustment locking member 21. The transverse adjustment seat 19 is slidably arranged in the transverse adjustment groove 162 in the transverse direction, and is used to adjust the position of the clamping finger clamping detection member 17 between the two clamping fingers 011. The longitudinal adjustment plate 20 is fixedly connected to the clamping finger clamping detection member 17, and the longitudinal adjustment plate 20 is slidably arranged in the transverse adjustment seat 19 in the longitudinal direction, and is used to adjust the position of the clamping finger clamping detection member 17 relative to the two clamping fingers 011, so that the clamping finger clamping detection member 17 is aligned with the two clamping fingers 011. The adjustment locking member 21 is used to lock and fix the longitudinal adjustment plate 20 to the transverse adjustment seat 19, to ensure that the position of the clamping finger clamping detection member 17 does not change during the test, the test structure is more accurate, and the test accuracy is higher. The adjustment locking member 21 can specifically be a ball screw, but is not limited to this. The lateral adjustment seat 19 has a vertical flange folded along the vertical direction, and the longitudinal adjustment plate 20 specifically has a connecting flange folded along the vertical direction, and the vertical flange is parallel to the connecting flange and is opposite to each other, and the two are fixedly connected together by adjusting the locking member 21. Of course, the connection method between the lateral adjustment seat 19 and the longitudinal adjustment plate 20 is not limited to this.

[0094] The performance test device of the electric clamp 01 also includes a sliding adjustment seat 22 and a vertical adjustment seat 23. The sliding adjustment seat 22 is fixedly connected to the clamping block clamping detection member 18. The vertical adjustment seat 23 is L-shaped and includes a vertically connected longitudinal support portion 231 and a vertical connection portion 232. Fig.10As shown, the longitudinal support portion 231 is connected to the sliding adjustment seat 22 and is used to provide support for the clamping block clamping detection member 18, and the vertical connection portion 232 is fixedly connected to the clamping fixed seat 11. The longitudinal support portion 231 is provided with a sliding adjustment hole 2311, and the sliding adjustment hole 2311 is penetrated by a sliding locking member 2312.
