Description

Technical Field

[0001] This utility model relates to the field of locking structure technology, and in particular to the locking structure of a clamp drive module. Background Technology

[0002] In the field of plastic welding machines, the fixture drive module is a key component for achieving automation and precision in welding operations. By driving the fixture to move on the guide rail, the plastic parts to be welded can be accurately delivered to the welding position, greatly improving welding efficiency and quality.

[0003] Currently, common clamp drive modules typically consist of two sliding plates mounted on a guide rail. A motor is mounted on one plate, and the clamp is mounted on the other. When the motor starts, it drives the clamp to move along the guide rail. However, during equipment operation, existing structural designs do not effectively fix and constrain the sliding plate at the motor mounting end. This leads to displacement or wobbling of the sliding plate at the motor mounting end under the vibration and driving force generated by the motor. This not only affects the accuracy of clamp movement and reduces the quality stability of plastic welding, but may also cause equipment failure due to abnormal movement of the sliding plate, shortening equipment lifespan and increasing maintenance costs and downtime. Therefore, this invention proposes a locking structure for the clamp drive module. Utility Model Content

[0004] The purpose of this utility model is to address the problem that in the commonly used plastic welding machine fixture drive module, the sliding plate at the motor mounting end lacks effective fixed constraint, which easily causes displacement and shaking during motor operation, resulting in a decrease in welding accuracy and quality, as well as equipment failure and increased maintenance costs. The present invention proposes a locking structure for the fixture drive module.

[0005] The technical solution of this utility model: a locking structure for a fixture drive module includes two sets of fixed plates mounted on a welding machine base, with two sets of sliding rods fixedly connected between the two sets of fixed plates; a positioning plate and a moving plate slidably connected to the two sets of sliding rods; a servo motor mounted at the bottom of the positioning plate; and the output end of the servo motor driving the moving plate through a lead screw nut; and a locking assembly mounted on one set of the sliding rods, which is used to lock the positioning plate.

[0006] Optionally, two sets of linear bearings are slidably connected to the two sets of sliding rods respectively, and the positioning plate and the moving plate are provided with mounting grooves corresponding to the linear bearings on their sides, and the linear bearings are installed in the mounting grooves.

[0007] Optionally, the locking assembly includes a knob disposed on the side of the positioning plate away from the linear bearing, a threaded sleeve fixedly connected to the side of the knob near the positioning plate, both the knob and the threaded sleeve being slidably connected to a slide rod, and the threaded sleeve being threadedly connected to the positioning plate.

[0008] Optionally, a stop inner ring is provided between the positioning plate and the threaded sleeve. The stop inner ring is sleeved on the outer ring of the slide rod. The stop inner ring is slidably connected in the positioning plate. The outer ring of the stop inner ring has an opening.

[0009] Optionally, a compression ring is fixedly connected to the end of the threaded sleeve away from the knob. The compression ring has a right-angled triangle cross-section, and the two ends of the stop inner ring are provided with oblique angles corresponding to the compression ring.

[0010] Optionally, a baffle is installed on the top of the positioning plate.

[0011] Optionally, the movable plate is provided with a clamp.

[0014] Furthermore, by adopting a knob and threaded sleeve design, operators can easily rotate the threaded sleeve to control the locking inner ring to tighten or loosen the slide bar, thereby achieving quick locking and unlocking of the positioning plate;

[0029] Example

[0030] like Figure 1 and Figure 2As shown, the locking structure of the clamp drive module proposed in this utility model includes two sets of fixing plates 2 installed on the welding base 1, and two sets of sliding rods 3 are fixedly connected between the two sets of fixing plates 2. The positions of the fixing plates 2 and the sliding rods 3 are fixed. This stable basic structure provides a reliable support frame for the operation of subsequent components and ensures the stability of the entire locking structure during operation.

[0031] Furthermore, the aforementioned locking structure includes a positioning plate 4 and a moving plate 5 slidably connected to two sets of sliding rods 3. Two sets of linear bearings 41 are slidably connected to the two sets of sliding rods 3 respectively. The sides of both the positioning plate 4 and the moving plate 5 have mounting grooves 42 corresponding to the linear bearings 41. The linear bearings 41 are installed in the mounting grooves 42, allowing the positioning plate 4 and the moving plate 5 to move smoothly, effectively reducing frictional resistance during movement, lowering energy consumption, and increasing the service life of the positioning plate 4 and the moving plate 5. A servo motor 7 is installed at the bottom of the positioning plate 4. The output end of the servo motor 7 drives the moving plate 5 through a lead screw nut. A clamp 8 is provided on the moving plate 5. After the positioning plate 4 is fixed, when the servo motor 7 starts, it drives the moving plate 5 to move, which in turn drives the clamped plastic part to move through the clamp 8, facilitating the welding operation. This transmission method enables precise control of the movement of the plastic part, meeting the high-precision process requirements of plastic welding. The top of the positioning plate 4 is equipped with a baffle 6, which serves as a protective measure to effectively prevent external debris from entering and affecting the operation of internal components, while also providing a certain degree of safety protection for operators.

[0032] For details, please refer to Figures 2 to 5The aforementioned locking structure includes a locking assembly 9 mounted on a set of slide rods 3, which is used to lock the positioning plate 4. The locking assembly 9 includes a knob 93 located on the side of the positioning plate 4 away from the linear bearing 41. A threaded sleeve 94 is fixedly connected to the knob 93 near the positioning plate 4. Both the knob 93 and the threaded sleeve 94 are slidably connected to the slide rods 3. The knob 93 facilitates the rotation of the threaded sleeve 94, allowing the operator to easily and conveniently operate the locking assembly 9. The threaded sleeve 94 is threaded into the positioning plate 4. After being threaded into the positioning plate 4, the threaded sleeve 94 moves along its own length direction when rotated. This threaded transmission method has the characteristics of simple structure and reliable transmission, accurately converting the rotational motion of the knob 93 into linear motion. A stop inner ring 91 is provided between the positioning plate 4 and the threaded sleeve 94. The stop inner ring 91 is fitted onto the outer ring of the slide rod 3 and is slidably connected to the positioning plate 4. The outer ring of the stop inner ring 91 has an opening 92. A compression ring 95 is fixedly connected to the end of the threaded sleeve 94 away from the knob 93. When the threaded sleeve 94 is rotated, the compression ring 95 rotates synchronously, and when the threaded sleeve 94 moves, the compression ring 95 moves synchronously. Through this linkage structure design, precise control of the stop inner ring 91 is achieved. The compression ring 95 has a right-angled triangle cross-section, and the two ends of the stop inner ring 91 are provided with bevels corresponding to the compression ring 95. When the threaded sleeve 94 rotates and drives the extrusion ring 95 to approach the linear bearing 41, the inclined surface of the extrusion ring 95 contacts the inclined angle of one end of the stop inner ring 91, causing the stop inner ring 91 to grip the slide rod 3, thereby fixing the position of the stop inner ring 91. In turn, the positioning plate 4 is fixed by the limiting effect of the stop inner ring 91, preventing the positioning plate 4 from shifting during operation. This unique locking method can provide a strong and stable locking force, effectively cope with the vibration and driving force generated by the motor operation, and ensure the accuracy of the movement of the fixture 8 and the reliability of the equipment operation during plastic welding.

[0033] In this embodiment, the positioning plate 4 needs to be fixed first. The operator rotates the knob 93, which drives the threaded sleeve 94 to rotate. Since the threaded sleeve 94 is threadedly connected to the positioning plate 4, the rotating threaded sleeve 94 moves along its own length. When the threaded sleeve 94 moves, it drives the compression ring 95 to move synchronously. The compression ring 95 has a right-angled triangle cross section. When it approaches the linear bearing 41, its inclined surface contacts one end of the stop inner ring 91 at an angle, compressing the stop inner ring 91. Because the stop inner ring 91 is fitted on the outer ring of the slide rod 3 and the outer ring has an opening 92, it will hug the slide rod 3 after being compressed, thereby fixing its own position. In turn, the positioning plate 4 is firmly locked through the limiting effect, resisting the vibration and driving force generated by the motor operation, and ensuring the accuracy of the movement of the clamp 8 and the reliability of the equipment operation.

[0034] When the position of the clamp 8 needs to be adjusted, the servo motor 7 starts because the position of the positioning plate 4 is locked. The moving plate 5 is driven by the lead screw nut. With the assistance of the linear bearing 41, the moving plate 5 slides smoothly along the slide bar 3, thereby driving the clamp 8 to move and sending the clamped plastic part to the welding position, thus achieving precise control.

[0035] When it is necessary to move the positioning plate 4 again, turn the knob 93 in the opposite direction. The compression ring 95 releases the compression on the inner stop ring 91, the inner stop ring 91 releases the slide rod 3, and the positioning plate 4 can be moved again.

[0036] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
