Description

Technical Field

[0001] This application relates to the field of precision machinery technology, and in particular to a jig. Background Technology

[0002] In the field of electric screwdriver assembly and quality control, concentricity is a core parameter affecting tightening accuracy and reliability. Currently, concentricity testing of electric screwdrivers mostly relies on manual operation, where the screwdriver and testing tool are held by hand. This method poses certain safety hazards, and during large-scale testing of electric screwdrivers, human error is significant, making prolonged operation impossible, thus reducing the accuracy and efficiency of concentricity testing. Therefore, the industry urgently needs a high-precision, high-efficiency, and high-safety concentricity testing method. Utility Model Content

[0003] In view of this, this application provides a fixture that can solve at least one of the above-mentioned technical problems.

[0004] This application provides a fixture configured to assemble an electric screwdriver and a testing component. The electric screwdriver includes a screwdriver bit. The fixture includes a base and a fixing module and a position adjustment module mounted on the base. The fixing module includes a fixing groove configured to detachably assemble the electric screwdriver. The position adjustment module includes a transmission component and a mounting platform, the mounting platform being configured to be driveably connected to the transmission component. The mounting platform is configured to assemble the testing component, and the transmission component is configured to drive the mounting platform to move, causing the testing component to abut against the screwdriver bit and detect the concentricity of the electric screwdriver.

[0005] The fixture provided in this application allows the electric screwdriver to be installed in a fixed slot and the test piece to be installed on a mounting table. This eliminates the need for manual handling of the electric screwdriver and the test piece to perform the concentricity test, thus achieving mechanized operation and improving the safety of the testing process. At the same time, the spatial position of the test piece can be precisely adjusted through the position adjustment module, which facilitates batch testing of the concentricity of the electric screwdrivers and improves the accuracy and efficiency of the concentricity test process.

[0006] In some embodiments, the fixing module includes a support frame and a fixing block. The support frame is detachably connected to the base, and the fixing block is detachably connected to the support frame. The fixing groove is formed on the top of the fixing block away from the base. The movement direction of the mounting platform is defined as a first direction, the thickness direction of the base is defined as a second direction, and the fixing groove passes through the fixing block along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0007] The electric screwdriver is fixed by a fixing groove formed by the recess on the fixing block. The fixing groove has a simple structure and the electric screwdriver is easy to install and remove from the fixing groove, which can improve the efficiency of electric screwdriver concentricity testing.

[0008] In some embodiments, the fixing module further includes a support plate and a pressure assembly, the support plate being detachably connected to the top of the support frame away from the base; the pressure assembly includes a bracket, a handle, a first connector, a second connector, and a pressure member; the bracket is detachably connected to the support plate, the bracket having a first pivot and a second pivot, the handle having a third pivot and a fourth pivot, the first connector being rotatably connected to the first pivot and the third pivot, the second connector being rotatably connected to the second pivot and the fourth pivot, and the pressure member being fixedly connected to the second connector; the handle is configured to move along the second direction, causing the pressure member to abut against the electric screwdriver.

[0009] By applying downward pressure to the electric screwdriver fixed in the mounting slot using the pressurizing component, the installation stability of the electric screwdriver can be further improved, the impact of external vibration or the vibration of the electric screwdriver itself on the detection accuracy during the concentricity test can be reduced, and the accuracy of the electric screwdriver concentricity test can be improved.

[0010] In some embodiments, the second connector is provided with a receiving portion, and the pressurizing member includes a main body, a first clamping portion and a second clamping portion; the first clamping portion and the second clamping portion are detachably connected to the main body; the receiving portion is sleeved on the main body, the first clamping portion abuts against the upper end of the receiving portion away from the base, and the second clamping portion abuts against the lower end of the receiving portion facing the base, so that the second connector is configured to drive the pressurizing member to move along the second direction.

[0011] By setting the first clamping part and the second clamping part, the length of the exposed receiving part of the main body can be adjusted, thereby adjusting the downward pressure applied to the electric screwdriver by the pressure assembly to adapt to the fixing process of electric screwdrivers of different specifications or strengths, and improving the applicability of the fixture.

[0012] In some embodiments, the transmission assembly includes a transmission base, a transmission screw, and a guide rod. The transmission base is detachably connected to the base, and the transmission screw and the guide rod are detachably connected to the transmission base. The mounting platform has a transmission hole and a guide hole. The mounting platform is configured to be mounted on the transmission base through the engagement of the transmission hole and the transmission screw, and the engagement of the guide hole and the guide rod. The transmission screw is configured to drive the mounting platform to move when rotated.

[0013] The cooperation between the transmission screw and the guide rod allows the mounting platform to move linearly and the displacement distance of the mounting platform to be controlled, thereby accurately adjusting the spatial position of the test piece. This facilitates batch testing of the concentricity of electric screwdrivers and improves the detection accuracy and efficiency of the concentricity detection process.

[0014] In some embodiments, the transmission assembly further includes a turntable connected to one end of the transmission screw, the turntable being configured to drive the transmission screw to rotate.

[0015] Using a turntable to control the rotation of the transmission screw can improve the efficiency of adjusting the mounting platform position, thereby improving the efficiency of detecting the concentricity of the electric screwdriver.

[0016] In some embodiments, the transmission assembly further includes a locking member, the mounting platform having a locking hole, and the locking member being configured to engage with the locking hole and restrict movement of the mounting platform.

[0017] After the mounting platform is moved to the preset position, the movement of the mounting platform is restricted by the locking device, so that the position of the test piece is fixed. At this time, the position of the electric screwdriver is also fixed, which can improve the detection accuracy of the electric screwdriver concentricity.

[0018] In some embodiments, the mounting platform is configured to fix the detection element by magnetic connection.

[0019] The test piece is connected to the mounting platform using a magnetic attraction method, which greatly improves the efficiency of assembly and disassembly.

[0020] In some embodiments, the base includes a plurality of support pads configured to adjust the height of the base.

[0021] By using support pads to adjust the height of the base, the structural error in concentricity detection caused by height differences in different areas of the base is reduced, thus improving detection accuracy. At the same time, the support pads can also provide a certain degree of shock absorption, reducing the shaking of the base and thus reducing the impact of base shaking on detection accuracy, further improving the accuracy of electric screwdriver concentricity detection.

[0022] In some embodiments, the fixing module further includes a reinforcing member that connects the support frame to the base.

[0023] The reinforcement can improve the installation stability of the support frame on the base, reduce the shaking of the support frame, and thus reduce the impact of the shaking of the support frame on the detection accuracy, thereby improving the accuracy of the electric screwdriver concentricity detection.

[0029] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] To address the problems of poor safety, low efficiency, and low accuracy in existing electric screwdriver concentricity testing methods, this application provides a fixture 10 that employs a mechanized device to improve the safety, efficiency, and accuracy of electric screwdriver concentricity testing.

[0031] Please refer to Figure 1The fixture 10 includes a base 1 and a fixing module 2 and a position adjustment module 3 mounted on the base 1. The base 1 provides a mounting platform for the fixing module 2 and the position adjustment module 3. The fixing module 2 is used to fix an electric screwdriver (not shown). The position adjustment module 3 includes a mounting platform 32, which is used to fix the detection element 20 and move the detection element 20. In some embodiments, the detection element 20 can perform concentricity detection on electric screwdrivers with different heads. For example, the shape of the electric screwdriver head includes, but is not limited to, flathead, crosshead, starhead, hexagonal, Torx, or square head. Depending on the required detection accuracy, the detection element 20 can be a dial indicator or a micrometer, which can be selected according to actual needs.

[0032] In some embodiments, please continue to refer to Figure 1 The base 1 includes multiple support pads 11, which are configured to adjust the height of the base 1. Adjusting the height of the base 1 using the support pads 11 reduces structural errors in concentricity detection caused by height differences between different areas of the base 1, thus improving detection accuracy. Simultaneously, the support pads 11 also provide some shock absorption, reducing the shaking of the base 1 and consequently minimizing the impact of the shaking on detection accuracy, further improving the accuracy of electric screwdriver concentricity detection.

[0033] Please refer to Figure 2 The fixing module 2 includes a fixing groove 221, which is formed on the top of the fixing block 22 away from the base 1. The movement direction of the mounting platform 32 is defined as the first direction X, and the thickness direction of the base is defined as the second direction Z. The fixing groove 221 extends through the fixing block 22 along the third direction Y. In some embodiments, the fixing module 2 includes a support frame 21 and a fixing block 22. The support frame 21 is a plate-like structure and is configured to be detachably connected to the base 1 to provide a mounting position for the fixing block 22. The fixing block 22 is configured to be detachably connected to the wall of the support frame 21. The shape of the fixing groove 221 matches part of the shape of the electric screwdriver, so that the electric screwdriver can be snapped into the fixing groove 221. This application uses the fixing groove 221 formed by the recess on the fixing block 22 to fix the electric screwdriver. The structure of the fixing groove 221 is simple, and the electric screwdriver is easy to install and remove from the fixing groove 221, which can improve the efficiency of the electric screwdriver concentricity test. The first direction X, the second direction Z, and the third direction Y are perpendicular to each other.

[0034] In some embodiments, please refer to Figure 2 and Figure 3The fixing block 22 is positioned close to the top of the support frame 21 along the second direction Z. The fixing module 2 also includes a support plate 23 and a pressure assembly 24. The support plate 23 is detachably connected to the top of the support frame 21 away from the base 1, and the pressure assembly 24 is detachably mounted on the support plate 23. Specifically, the pressure assembly 24 includes a bracket 241, a handle 242, a first connector 243, a second connector 244, and a pressure component 245. The bracket 241 is detachably connected to the support plate 23. The bracket 241 has a first rotating shaft 2411 and a second rotating shaft 2412 distributed along the first direction X. The handle 242 has a third rotating shaft 2421 and a fourth rotating shaft 2422 distributed along its length. The first connector 243 has a first shaft hole 2431 and a second shaft hole 2432, and the second connector 244 has a third shaft hole 2441 and a fourth shaft hole 2442. This allows the first connector 243 to be configured to... The first shaft hole 2431 is rotatably connected to the first rotating shaft 2411, and rotatably connected to the third rotating shaft 2421 via the second shaft hole 2432. The second connecting member 244 is configured to rotatably connect to the second rotating shaft 2412 via the third shaft hole 2441, and rotatably connect to the fourth rotating shaft 2422 via the fourth shaft hole 2442. The pressure member 245 is configured to be fixedly connected to the second connecting member 244. Thus, when the handle 242 is moved along the second direction Z by an applied force, the pressure member 245 can move along the second direction Z to abut against the electric screwdriver through the cooperation of the bracket 241, the first connecting member 243, and the second connecting member 244. By applying downward pressure to the electric screwdriver fixed in the fixing groove 221 through the pressure assembly 24, the installation stability of the electric screwdriver can be further improved, the influence of external vibration or the vibration of the electric screwdriver's own rotation on the detection accuracy during the subsequent concentricity test can be reduced, and the accuracy of the electric screwdriver concentricity detection can be improved.

[0035] In some embodiments, the second connector 244 is provided with a receiving portion 2443 that extends through the second connector 244 along the second direction Z. The pressure member 245 includes a main body 2451, a first clamping portion 2452 and a second clamping portion 2453. The first clamping portion 2452 and the second clamping portion 2453 are detachably connected to the main body 2451. At least a portion of the width of the first clamping portion 2452 and the second clamping portion 2453 is greater than the width of the receiving portion 2443. The receiving portion 2443 is sleeved on the main body 2451. The first clamping portion 2452 abuts against the upper end of the receiving portion 2443 along the second direction Z, and the second clamping portion 2453 abuts against the lower end of the receiving portion 2443 facing the base 1. This allows the pressure member 245 to move along the second direction Z when the second connector 244 moves along the second direction Z. In this application, the first clamping part 2452 and the second clamping part 2453 are detachably connected to the main body part 2451. The positions of the first clamping part 2452 and the second clamping part 2453 on the main body part 2451 can be adjusted to adjust the length of the exposed receiving part 2443 of the main body part 2451. The resistance force applied to the electric screwdriver by the main body part 2451 of different lengths is different, thereby adjusting the downward pressure applied to the electric screwdriver by the pressure assembly 24 to adapt to the fixing process of electric screwdrivers of different specifications or strengths, and improving the applicability of the fixture 10.

[0036] In some embodiments, the fixing module 2 further includes a reinforcing member 25, which is configured to connect the support frame 21 and the base 1. The reinforcing member 25 can improve the installation stability of the support frame 21 on the base 1, reduce the shaking of the support frame 21, thereby reducing the impact of the electric screwdriver's shaking on the detection accuracy and improving the accuracy of the electric screwdriver concentricity detection.

[0037] Please refer to Figure 4 The position adjustment module 3 includes a transmission assembly 31 and a mounting platform 32. The mounting platform 32 is used to mount the test piece 20. The mounting platform 32 is configured to be connected to the transmission assembly 31. The transmission assembly 31 is used to adjust the position of the mounting platform 32 along the first direction X so that the test piece 20 abuts against the electric screwdriver and tests the concentricity of the electric screwdriver.

[0038] In some embodiments, the detection element 20 and the mounting platform 32 are magnetically connected. Using a magnetic connection to connect the detection element 20 and the mounting platform 32 results in high efficiency in assembly and disassembly.

[0039] In some embodiments, the transmission assembly 31 includes a transmission base 311, a transmission screw 312, and a guide rod 313. The transmission base 311 is detachably connected to the base 1. The transmission base 311 includes a base plate 3111 and two side plates 3112 arranged opposite each other along a first direction X. The transmission screw 312 and the guide rod 313 are located between the two side plates 3112 and are configured to be detachably connected to the two side plates 3112. The mounting platform 32 has a transmission hole 321 and a guide hole 322. The mounting platform 32 is configured to be mounted on the transmission base 311 through the engagement of the transmission hole 321 with the transmission screw 312 and the engagement of the guide hole 322 with the guide rod 313. The transmission screw 312 is configured to drive the mounting platform 32 to move when rotated. In this application, the cooperation between the transmission screw 312 and the guide rod 313 can cause the mounting table 32 to move linearly along the first direction X. The transmission screw 312 can precisely control the displacement distance of the mounting table 32, thereby precisely adjusting the spatial position of the test piece 20, which facilitates batch testing of the concentricity of electric screwdrivers and improves the detection accuracy and efficiency of the concentricity detection process.

[0040] As an optional technical solution of this application, a structure such as a robotic arm can be set on the test piece 20, so that the test piece 20 can be connected to the mounting table 32 by the robotic arm, thereby allowing for more precise adjustment of the position of the test piece 20 and further improving the accuracy of the electric screwdriver concentricity test.

[0041] In some embodiments, the transmission assembly 31 further includes a turntable 314, which is connected to one end of the transmission screw 312. The turntable 314 is configured to drive the transmission screw 312 to rotate. By using the turntable 314 to control the rotation of the transmission screw 312, the efficiency of adjusting the position of the mounting platform 32 can be improved, thereby improving the detection efficiency of the electric screwdriver concentricity.

[0042] In some embodiments, the transmission assembly 31 further includes a locking member 315. The mounting platform 32 has a locking hole 323 that communicates with the guide hole 322. The locking member 315 is configured to cooperate with the locking hole 323 to restrict the movement of the mounting platform 32. After the mounting platform 32 moves to a preset position, the locking member 315 passes through the locking hole 323 and enters the guide hole 322, abutting against the guide rod 313. This causes the end of the locking member 315 to abut against the guide rod 313, thereby restricting the movement of the mounting platform 32 and fixing the position of the detection member 20. At this time, the position of the electric screwdriver is also fixed, which can improve the detection accuracy of the electric screwdriver concentricity.

[0043] It should be noted that when the connection between the various structures in this solution is a detachable connection, it includes, but is not limited to, threaded connection, pin connection, snap connection or strap connection, etc., which can be selected according to actual needs.

[0044] The fixture 10 provided in this application allows the electric screwdriver to be installed in the fixing slot 221. The mounting table 32 is configured to fix the test piece by magnetic connection, eliminating the need for manual handling of the electric screwdriver and the test piece 20 to perform the concentricity test process, thus achieving mechanized operation and improving the safety of the test process. At the same time, the spatial position of the test piece 20 can be precisely adjusted by the position adjustment module 3, facilitating batch testing of the concentricity of the electric screwdrivers and improving the detection accuracy and efficiency of the concentricity test process.

[0045] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application.
