Description

Technical Field

[0001] This invention relates to the field of measuring equipment technology, and in particular to auxiliary measuring fixtures and measuring systems. Background Technology

[0002] Fixtures are a broad category of tools used in woodworking, metalworking, fitter work, machinery, electrical control, and other handicrafts. They are primarily used to assist in controlling position and / or movement. Fixtures can be divided into three categories: process assembly fixtures, project testing fixtures, and circuit board testing fixtures.

[0003] After Hosing completes the side laser marking on the wireless charging connector of the smartwatch, the dimensions of the side marking position need to be measured. However, due to the special location of the side marking, conventional measurement methods cannot effectively measure it.

[0004] Currently, there is no low-cost, high-efficiency fixture-assisted measurement method. After the product is placed on the testing platform, the hosing moves with the platform, making accurate positioning impossible. This leads to large measurement errors and the risk of dimensional defects. Furthermore, during the hosing's adjustment and movement for testing, there are risks of positional shifts, unstable positioning, and unstable gripping points, requiring repeated calibration of the hosing's positioning and gripping points, resulting in low testing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary measuring fixture and measuring system to solve the problems of low measuring efficiency and inability to guarantee the measuring accuracy of the product under test.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An auxiliary measurement fixture for assisting in the measurement of a product under test includes a fixture frame and a positioning shaft. The positioning shaft is rotatably connected to the fixture frame and can rotate around its axis. An equally spaced positioning component and an assembly component are fixedly connected to the positioning shaft. The equally spaced positioning component allows the assembly component to be positioned at one of multiple measurement positions, and the positioning shaft rotates at the same angle between any two adjacent measurement positions. The assembly component includes a positioning frame, a sliding frame, and a handle. The positioning frame is fixed to the positioning shaft, and an elastic element is clamped between the positioning frame and the sliding frame. The elastic element can drive the sliding frame to slide along the working direction and stop at the assembly position. The positioning frame and the sliding frame located at the assembly position can fix the product under test. The handle allows the sliding frame located at the assembly position to move relative to the positioning frame.

[0008] As a preferred technical solution for auxiliary measurement fixtures, the product to be tested is an annular tube, a fixed clamp is fixed on the positioning frame, and a movable clamp is fixed on the sliding frame. Both the fixed clamp and the movable clamp are arc-shaped parts, and the fixed clamp and the movable clamp located at the assembly position can simultaneously abut against the inner surface of the product to be tested.

[0009] As a preferred technical solution for auxiliary measuring fixtures, the side of the product to be measured has a through hole for threading, and the fixed fixture has a protruding positioning pin that can be matched and connected to the through hole.

[0010] As a preferred technical solution for auxiliary measurement fixtures, the product to be tested is an annular tube, and when the product to be tested is fixed to the assembly component, the product to be tested is coaxial with the positioning shaft.

[0011] As a preferred technical solution for auxiliary measuring fixture, the positioning frame is provided with a fixed shaft, the handle is rotatably connected to the fixed shaft and can rotate around the axis of the fixed shaft, the elastic element is used to push the sliding frame and make the sliding frame contact the handle, and the sliding frame can move closer to or away from the positioning frame as the handle rotates.

[0012] As a preferred technical solution for auxiliary measuring fixtures, the handle is a rod-shaped component with one end being a contact end and the other end being a free end. By screwing the free end of the handle, the handle can rotate between a first position and a second position. When the handle is in the first position, the sliding frame contacts the side of the handle, placing the sliding frame in the assembly position. When the handle is in the second position, the sliding frame contacts the end face of the contact end of the handle, causing the sliding frame to leave the assembly position.

[0013] As a preferred technical solution for auxiliary measuring fixture, at least one guide rod is fixedly connected to the positioning frame, and a clearance hole is provided on the sliding frame. The number of clearance holes is the same as the number of guide rods, and each guide rod passes through one clearance hole. Both the guide rod and the clearance hole extend along the working direction.

[0014] As a preferred technical solution for the auxiliary measuring fixture, the elastic element includes a spring, the number of which is the same as the number of guide rods, and each guide rod is fitted with a spring, the two ends of which are respectively connected to the sliding frame and the positioning frame.

[0015] As a preferred technical solution for auxiliary measurement fixtures, the positioning shaft passes through the fixture frame, and the equally spaced positioning component and the assembly component are located on both sides of the fixture frame.

[0016] The measurement system includes a measurement device and the aforementioned auxiliary measurement fixture, wherein the measurement device is used to measure the product to be measured fixed to the assembly assembly.

[0017] The beneficial effects of this invention are:

[0018] This auxiliary measuring fixture, with its equally spaced positioning components, ensures that the angles of the assembled components change uniformly when their measurement positions are altered, thus achieving equally spaced positioning of the assembled components. These improvements facilitate precise adjustment of the posture of the product under test during measurement operations, thereby ensuring the accuracy and efficiency of the measurement operation. The sliding frame, designed to slide relative to the positioning frame, combined with the handle and elastic elements, determines the method of fixing the product under test, enabling adjustment of the sliding frame's position. These structural improvements facilitate the assembly, disassembly, and fixing of the product under test on the assembled components, achieving accurate fixation and contributing to the smooth completion of the measurement operation.

[0027] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] like Figures 1-3As shown, this embodiment provides an auxiliary measurement fixture for assisting in the measurement of a product under test, including a fixture frame 100 and a positioning shaft 210. The positioning shaft 210 is rotatably connected to the fixture frame 100 and can rotate around its axis. An equally spaced positioning component and an assembly component are fixedly connected to the positioning shaft 210. The equally spaced positioning component enables the assembly component to be positioned in one of multiple measurement positions, and the positioning shaft 210 rotates at the same angle between any two adjacent measurement positions. The assembly component includes a positioning frame 230, a sliding frame 240, and a handle 260. The positioning frame 230 is fixedly connected to the positioning shaft 210, and an elastic element 250 is clamped between the positioning frame 230 and the sliding frame 240. The elastic element 250 can drive the sliding frame 240 to slide along the working direction and stop at the assembly position. The positioning frame 230 and the sliding frame 240 located at the assembly position can fix the product under test, and the handle 260 can move the sliding frame 240 located at the assembly position relative to the positioning frame 230.

[0029] This auxiliary measuring fixture, with the aid of equally spaced positioning components, ensures that the angles of the assembly components change uniformly when the measurement position is altered, thereby achieving equally spaced positioning of the assembly components. These improvements help to accurately adjust the posture of the product under test during measurement operations, thus ensuring the accuracy of the measurement operation and improving its efficiency. The sliding frame 240, which can slide relative to the positioning frame 230, together with the handle 260 and the elastic element 250, determines the method of fixing the product under test, thereby enabling the adjustment of the position of the sliding frame 240. These structural improvements facilitate the disassembly and fixing of the product under test on the assembly components, achieving accurate fixing of the product under test and contributing to the smooth completion of the measurement operation.

[0030] In this embodiment, the product under test is the hosing on the wireless charging connector of a smartwatch, and there is a need to measure the evenly spaced marking positions on the outer surface of the hosing.

[0031] In this embodiment, the jig frame 100 is provided with a plunger 121; the equally divided positioning assembly includes a positioning wheel 220, which is coaxially fixed to the positioning shaft 210. The side of the positioning wheel 220 is recessed with a plurality of positioning grooves 221, which are evenly distributed around the axis of the positioning wheel 220; the plunger 121 can be matched and embedded in the positioning groove 221. When the plunger 121 is embedded in the positioning groove 221, the assembly assembly is in one of a plurality of measurement positions.

[0032] This auxiliary measuring fixture, with the help of the assembly components, facilitates the smooth completion of the measurement operation. The design of multiple evenly spaced positioning grooves 221 around the axis of the positioning wheel 220, along with the matching and embedding of the plunger 121 within the positioning grooves 221, ensures that the angle of change of the assembly components is the same when the measurement position is altered, thereby achieving equal positioning of the assembly components. These improvements help to achieve precise adjustment of the posture of the product under test during measurement operations, thus ensuring the accuracy of the measurement operation and improving its efficiency.

[0033] In this embodiment, the jig frame 100 includes a plunger bracket 120, and the plunger 121 includes a plunger head and an elastic connector. The elastic connector is used to drive the plunger head to move away from the plunger bracket 120 along the length direction of the elastic connector. With the above design, the elastic connector can drive the plunger head to abut against the side of the positioning wheel 220, and can match and connect when the plunger head extends into the positioning groove 221. The above design limits the range of motion of the plunger 121, realizes the planning of the movement trajectory of the plunger 121, and ensures that the plunger 121 can be smoothly matched and embedded in the positioning groove 221, further facilitating the equal positioning of the assembly components.

[0034] Furthermore, the end of the plunger head that mates with the positioning groove 221 is a spherical head, and the positioning groove 221 is a hemispherical groove. The spherical head can be fitted into the hemispherical groove. The fit between the spherical head and the hemispherical groove is tight and the force is evenly distributed. While successfully completing the fitting, it also reduces the degree of rigid collision between the plunger 121 and the positioning wheel 220. This reduces the risk of damage to the plunger head and the positioning groove 221, reduces the probability of irreversible deformation of the plunger support 120 and positional displacement of the positioning wheel 220, and extends the service life of the auxiliary measuring fixture. Specifically, the plunger head is a sphere.

[0035] Preferably, the elastic connector is a spring, with its two ends connected to the plunger bracket 120 and the plunger head, respectively. The design of using a spring to connect the plunger bracket 120 and the plunger head is simple and reliable, has low production costs, occupies little space, and can smoothly push the plunger head, ensuring the smooth operation of the plunger 121.

[0036] In this embodiment, the product under test is an annular tube. A fixed clamp 231 is fixed on the positioning frame 230, and a movable clamp 241 is fixed on the sliding frame 240. Both the fixed clamp 231 and the movable clamp 241 are arc-shaped components. The fixed clamp 231 and the movable clamp 241, located at the assembly position, can simultaneously abut against the inner surface of the product under test. This design allows the fixed clamp 231 and the movable clamp 241 to support the product under test from the inside, achieving accurate fixation of the product under test and reducing the risk of deformation. The above structure is simple and reliable, with high stability and avoids obstruction of the outer surface of the product under test, facilitating the measurement operation. The arc-shaped structure of the fixed clamp 231 and the movable clamp 241, combined with the annular tube design of the product under test, ensures a proper fit between the assembly components and the product under test.

[0037] Preferably, the elastic element 250 is used to push the sliding frame 240 away from the positioning frame 230, and the handle 260 allows the sliding frame 240 in the assembly position to move towards the positioning frame 230. This design ensures that the operator can adjust the position of the sliding frame 240 using the handle 260, reducing the distance between the fixed clamp 231 and the movable clamp 241. This allows the operator to easily complete the assembly and disassembly of the product under test, ensuring the stability of the assembly component in fixing the product under test.

[0038] Furthermore, the product under test has a through-hole on its side, and the fixed clamp 231 has a protruding positioning pin 232 that can be matched and connected to the through-hole. This design ensures that the product under test can be accurately installed on the assembly component, greatly reducing the risk of positional displacement of the product under test, and also avoiding relative sliding of the product under test relative to the fixed clamp 231 and the movable clamp 241, further improving the stability of the product under test fixed on the assembly component.

[0039] In this embodiment, when the product under test is fixed to the assembly assembly, the product under test is coaxial with the positioning shaft 210. This design avoids positional shifts in the product under test, reduces variables during measurement, and ensures the accuracy of the measurement results. Simultaneously, this design also adjusts the positions of the fixed fixture 231 and the movable fixture 241 on the assembly assembly, facilitating adjustments to the assembly assembly layout. This improves the stress on the positioning shaft 210 during rotation, reduces the risk of damage to the positioning shaft 210, and extends the service life of the auxiliary measuring fixture.

[0040] Preferably, the positioning frame 230 has a protruding fixed shaft 233. The handle 260 is rotatably connected to the fixed shaft 233 and can rotate around the axis of the fixed shaft 233. The elastic element 250 is used to push the sliding frame 240 and bring the sliding frame 240 into contact with the handle 260. The sliding frame 240 can move closer to or away from the positioning frame 230 as the handle 260 rotates. With the above design, the handle 260 can be mounted on the positioning frame 230 by rotating relative to the fixed shaft 233. The above design limits the range of motion of the handle 260, realizes the planning of the movement trajectory of the handle 260, ensures that the handle 260 can push the sliding frame 240 located in the assembly position, and at the same time reduces the space occupied by the handle 260, making it convenient for the operator to perform screwing operations on the handle 260.

[0041] Furthermore, the handle 260 is a rod-shaped component, with one end being a contact end and the other end being a free end. By turning the free end of the handle 260, the handle 260 can rotate between a first position and a second position. When the handle 260 is in the first position, the sliding frame 240 contacts the side of the handle 260, placing the sliding frame 240 in the assembly position. When the handle 260 is in the second position, the sliding frame 240 contacts the end face of the contact end of the handle 260, causing the sliding frame 240 to leave the assembly position. Through the above design, the change in the contact position between the contact end of the handle 260 and the sliding frame 240 during rotation can cause a change in the distance between the sliding frame 240 and the positioning frame 230, thereby causing the fixed clamp 231 and the movable clamp 241 to fix or release the product to be tested. The above design is simple and reliable, with high working stability and good adjustment effect. The free end provides a gripping part for the operator, facilitating the operator's turning operation of the handle 260.

[0042] In this embodiment, at least one guide rod 234 is fixedly connected to the positioning frame 230, and the sliding frame 240 has clearance holes. The number of clearance holes is the same as the number of guide rods 234, and each guide rod 234 passes through one clearance hole. Both the guide rods 234 and the clearance holes extend along the working direction. The design of the guide rods 234 and clearance holes effectively limits the movement trajectory of the sliding frame 240, reduces the risk of positional deviation of the sliding frame 240, and ensures the smooth operation of the assembly components.

[0043] Furthermore, the elastic element 250 includes a spring, the same number as the guide rods 234, and each guide rod 234 is fitted with a spring. The two ends of the spring are connected to the sliding frame 240 and the positioning frame 230, respectively. The use of springs in the elastic element 250 is simple and reliable, has low production costs, and occupies little space. It can smoothly fulfill the action requirement of pushing the sliding frame 240 to the handle 260, further ensuring the smooth operation of the assembly.

[0044] In this embodiment, the positioning shaft 210 passes through the fixture frame 100, and the equally spaced positioning component and the assembly component are located on opposite sides of the fixture frame 100. This design optimizes the layout of the equally spaced positioning component and the assembly component, achieving accurate positioning of the positioning shaft 210, reducing the space occupied by the auxiliary measuring fixture, lowering the risk of accidents caused by instability in the auxiliary measuring fixture, and ensuring the stable operation of the auxiliary measuring fixture.

[0045] Preferably, the assembly component is mounted on one end of the positioning shaft 210, and the positioning wheel 220 is fixed to the other end of the positioning shaft 210. This design simplifies the layout of the assembly component and the positioning wheel 220 on the positioning shaft 210, optimizes the stress on the positioning shaft 210, reduces the space occupied, and ensures the smooth rotation of the positioning shaft 210 and the smooth operation of the equally divided positioning component and the assembly component.

[0046] Furthermore, the fixture frame 100 also includes a base 110 and a fixed bracket 130 fixed to the base 110. The positioning shaft 210 passes through the fixed bracket 130 and is rotatably connected to the fixed bracket 130. The plunger bracket 120 is fixed to the base 110, and the plunger 121 is located directly below the positioning wheel 220. The fixed bracket 130 ensures that the positioning shaft 210 can rotate smoothly and reduces the risk of positional displacement of the positioning shaft 210. The design of the plunger bracket 120 being fixed to the base 110 ensures the determination of the relative position of the plunger 121 and the fixed bracket 130, ensuring that the plunger 121 can be accurately matched and embedded in each positioning groove 221, thereby further ensuring the stable operation of the equally spaced positioning assembly.

[0047] Furthermore, an auxiliary bracket 140 is also fixedly connected to the fixed bracket 130, and the positioning shaft 210 passes through the auxiliary bracket 140 and is rotatably connected to it. The auxiliary bracket 140 allows the fixture frame 100 to be rotatably connected to the positioning shaft 210 simultaneously through both the fixed bracket 130 and the auxiliary bracket 140. These improvements effectively enhance the stability of the positioning shaft 210's operation, further reduce the risk of positional displacement of the positioning shaft 210 relative to the fixture frame 100, and further ensure the stable operation of the auxiliary measuring fixture.

[0048] This embodiment also provides a measurement system, including a measurement device and the aforementioned auxiliary measurement fixture. The measurement device is used to measure the product to be measured that is fixed to the assembly assembly.

[0049] With the help of measurement equipment, this measurement system can successfully complete the measurement operation of the product under test located at each measurement position.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
