Description

Technical Field

[0001] This utility model relates to the field of positioning fixtures for bow-shaped workpieces, specifically a clamping device for a fixture with positioning function. Background Technology

[0002] In the fields of machinery manufacturing, packaging, and assembly, bow-shaped workpieces, as a common type of irregular structural component, are widely used in industries such as automotive parts, electronic devices, and medical equipment. The fixing and positioning accuracy of these workpieces directly affects the efficiency and product quality of subsequent production processes, thus placing high demands on the adaptability, stability, and versatility of their clamping devices. Currently, the industry commonly uses a conformal clamping solution for clamping and positioning bow-shaped workpieces. This involves designing a clamping structure that perfectly matches the workpiece's shape, based on its curvature, chord length, and notch morphology, and achieving tight clamping by filling the workpiece's curved notch. While this method can guarantee a certain level of positioning accuracy in the mass production of single-model workpieces, it reveals significant shortcomings in the production of multiple models and specifications of bow-shaped workpieces. In actual production, many serialized products often include multiple models of bow-shaped workpieces with the same diameter but different chord lengths. Some products even involve both superior bow shapes (bow shapes with an arc length less than a semicircle) and inferior bow shapes (bow shapes with an arc length greater than a semicircle). Because the structure of traditional fixtures is strictly bound to the shape of specific workpieces, one fixture can only be used for one model of bow-shaped workpiece. When the number of product models increases to more than ten or even dozens, companies need to customize fixtures for each model, resulting in a significant increase in fixture procurement costs, storage costs, and maintenance costs, which seriously restricts the improvement of production efficiency. More importantly, if a simplified clamping solution is adopted to reduce costs (such as rough fixation using only two side clamps), it will cause uncertainty in the workpiece's posture: the bow-shaped workpiece may rotate, tilt, or shift in the fixture, which will not only cause the workpiece to be arranged in a messy manner during the packaging process, affecting the neatness of the product's appearance, reducing the product's display effect and market competitiveness; during the assembly process, posture deviation will cause the workpiece to be unable to accurately align with the assembly benchmark, resulting in problems such as excessive assembly errors, damage to parts, and even production stoppage.

[0019] The clamping adjustment component 6 is set on the first square base 1, and the output end of the clamping adjustment component 6 is in frictional contact with the first clamp 3. The clamping adjustment component 6 is used to adjust the posture of the workpiece, so that multiple sets of workpieces are in the preset posture, which is convenient for assembly or packaging.

[0020] The workpiece posture positioning component 7 includes a positioning signal source and a positioning signal receiver. The positioning signal source is disposed within a first square base 1, and the positioning signal receiver is disposed within a second square base 2. The workpiece posture positioning component 7 can detect the workpiece posture and position it accordingly, facilitating adjustment to a preset posture.

[0021] Furthermore, the first square base 1 and the second square base 2 are provided with clamping slots 8 corresponding to the clamps. The first square base 1 and the second square base 2 are provided with bearings 9 at the center of the clamping slots 8, and the clamps are provided with rotating shafts 10. The clamps are all engaged in the clamping slots 8, and the rotating shafts 10 are coaxially and fixedly connected to the inner ring of the bearings 9. The first clamp 3 is rotatably connected to the first square base 1, and the second clamp 4 is rotatably connected to the second square base 2.

[0022] Furthermore, the first fixture 3 has multiple sets of docking holes 11, which are symmetrically distributed around the circumference.

[0023] Furthermore, the second clamp 4 is provided with docking rods 12 corresponding to multiple sets of docking holes 11, and the docking rods 12 are inserted into the docking holes 11. The docking holes 11 and the docking rods 12 cooperate to prevent the first clamp 3 and the second clamp 4 from rotating relative to each other.

[0024] Furthermore, the first square base 1 is provided with an adjustment component groove 13 that communicates with the clamp groove 8.

[0025] Furthermore, the fixture orientation assembly 6 includes a servo motor 14 and a friction roller 15. The servo motor 14 is fixedly mounted at the bottom of the orientation assembly slot 13, and the output shaft of the servo motor 14 is coaxially connected to the friction roller 15. The friction roller 15 makes frictional contact with the first fixture 3. The servo motor 14 is the power source, driving the friction roller 15 to rotate. The friction roller 15 uses friction to rotate the first fixture 3, the second fixture 4, and the workpiece. The rotation control of the servo motor 14 uses existing technology, and the controller is usually provided by the motor supplier.

[0026] Furthermore, a first inner cavity 16 is formed within the first square base 1, and a second inner cavity 17 is formed within the second square base 2. A through-type wire channel 18 is formed on one side of both the first inner cavity 16 and the second inner cavity 17. The wire channel 18 facilitates the passage of power lines and signal feed lines. The first inner cavity 16 can be connected to the directional component slot 13, allowing the wires of the servo motor 14 to pass through the wire channel 18.

The first circular circuit board 19 is fixedly disposed within the first inner cavity 16, and the multiple sets of laser generators 20 are fixedly disposed on the first circular circuit board 19, with the laser generators 20 positioned on the side of the first circular circuit board 19 facing the first clamp 3. The multiple sets of laser generators 20 are symmetrically distributed circumferentially. The laser generators 20 can be laser diodes. The number of laser generators 20 (with a one-to-one correspondence between the optical aperture and the laser generator 20) determines the positioning accuracy. The light signal points blocked by the workpiece constitute the fuzzy posture of the workpiece. The angle between two adjacent sets of laser generators 20 is the systematic error. The more laser generators 20 there are, the smaller the angle, and the more accurate the positioning.

[0028] Furthermore, the positioning signal receiver includes a second circular circuit board 21 and multiple sets of optical signal receivers 22. The second circular circuit board 21 is fixedly disposed within the second inner cavity 17, and the multiple sets of optical signal receivers 22 are fixedly disposed on the second circular circuit board 21, with the optical signal receivers 22 positioned on the side of the second circular circuit board 21 facing the second clamp 4. The multiple sets of optical signal receivers 22 are symmetrically distributed in a circle, and each optical signal receiver 22 corresponds one-to-one with the laser generator 20. The optical signal receivers 22 can use photodiodes. The optical signal receivers 22 receive the optical signals from the laser generator 20 and convert them into electrical signals. The optical signal receivers 22 that do not receive signals have their light blocked by the bow-shaped workpiece, thus determining the posture of the bow-shaped workpiece. The preset posture is determined by a preset blocking potential, and the high and low potentials are compared to detect whether the preset posture is met. The code used is all existing technology, and the algorithm adopts the method of comparing potential differences.

[0029] Furthermore, the first square base 1 has multiple sets of first optical through holes 23, the first clamp 3 has multiple sets of second optical through holes 24, the second clamp 4 has multiple sets of third optical through holes 25, and the second square base 2 has multiple sets of fourth optical through holes 26. Each of the first optical through holes 23, 24, 25, and 26 corresponds one-to-one with the laser generator 20. Since the light passes through multiple sets of narrow optical through holes, similar to multiple pinhole apertures, collimating lenses and other optical devices are not required.

[0031] Working principle: The working principle of this positioning fixture clamping device is based on the collaborative operation of multiple components. Through an integrated process of rigid support, precise clamping, posture detection and dynamic adjustment, it can achieve stable fixation and posture calibration of various bow-shaped workpieces of the same diameter.

[0032] During operation, the bow-shaped workpiece is first placed between the first clamp 3 and the second clamp 4. The rigid structure of the first square base 1 and the second square base 2 provides clamping force. The two sets of square bases transmit the force to the corresponding clamps through mechanical transmission, causing the first clamp 3 and the second clamp 4 to move closer to each other until the workpiece is tightly clamped in the circular workpiece cavity 5 formed by their cooperation. At this time, the docking rods 12 on the first clamp 3 and the second clamp 4 are precisely inserted into the docking holes 11. Mechanical limiting prevents relative rotation of the clamps, ensuring that the workpiece will not be displaced by external forces during the clamping process.

[0033] After the workpiece is initially clamped, the workpiece attitude positioning component 7 initiates the attitude detection process: On the first annular circuit board 19 within the first square base 1, multiple sets of circumferentially symmetrically distributed laser generators 20 emit detection beams. The light beams pass sequentially through the first optical aperture 23, the second optical aperture 24, the third optical aperture 25, and the fourth optical aperture 26, finally reaching the optical signal receiver 22 on the second annular circuit board 21 within the second square base 2. Because the arc-shaped structure of the bow-shaped workpiece partially blocks the light path, the receivers that do not receive the light signal will form a specific electrical signal combination. By comparing this signal combination with the standard signal of the preset attitude, the current angular offset and tilt state of the workpiece can be determined.

[0034] When the workpiece posture is detected to be inconsistent with the preset requirements, the fixture orientation component 6 initiates the adjustment program: the servo motor 14 drives the friction roller 15 to rotate within the orientation component slot 13, using the friction between the roller and the first fixture 3 to rotate the fixture around the inner ring of the bearing 9 (the first fixture 3 and the second fixture 4 rotate synchronously through a docking structure). During this process, the workpiece rotates together with the fixture, while the workpiece posture positioning component 7 continuously performs beam detection and provides real-time feedback on posture change data. When the signal combination received by the optical signal receiver 22 perfectly matches the preset posture, the servo motor 14 stops working, completing the posture calibration.

[0035] It is worth noting that the device is compatible with various bow-shaped workpieces of the same diameter through the universal design of the circular workpiece cavity 5: regardless of whether the workpiece is of superior or inferior bow shape, as long as its diameter matches the circular workpiece cavity 5, it can be stably clamped; at the same time, the circumferential distribution design of multiple laser generators 20 and optical signal receivers 22 ensures that workpieces of different chord lengths can always achieve posture recognition through changes in the optical path obstruction mode during rotation adjustment. The wire channel 18 provides an integrated wiring path for the power lines and signal lines of the servo motor 14 and the positioning components, avoiding line interference from affecting the stability of the device's operation.

[0036] Through the above process, the device realizes the automated operation from workpiece clamping to posture calibration, which not only solves the problem of adapting traditional fixtures to multiple workpiece models, but also ensures the quality of subsequent packaging and assembly operations through precise posture control.
