Description

Technical Field

[0001] This utility model relates to the field of plastic parts adhesive bonding fixtures, and in particular to a new type of high-efficiency plastic parts adhesive bonding fixture. Background Technology

[0002] Current plastic part bonding processes commonly suffer from drawbacks such as low operational efficiency, insufficient positioning accuracy, uneven force application, and poor curing stability. Traditional bonding primarily relies on manual hand operation or simple fixtures, which is not only time-consuming and labor-intensive but also makes it difficult to accurately control the bonding position and pressure, easily leading to glue overflow, misalignment, or incomplete bonding, thus affecting product yield. Especially when multi-point synchronous pressing or bonding complex curved surfaces is required, existing tooling often lacks reliable linkage mechanisms and pressure holding functions, requiring operators to repeatedly adjust the fixtures, resulting in low efficiency and difficulty in ensuring consistency.

[0003] In addition, plastic parts are relatively weak, and excessive local pressure can easily cause deformation, while insufficient pressure may result in an incomplete adhesive layer, affecting the final bonding strength. During the curing process of the adhesive, traditional tooling often cannot provide a continuous and stable clamping force. When the workpiece is disturbed by external forces or when its own stress is released, it is prone to displacement, causing bonding failure. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is: how to provide a new and efficient plastic part gluing fixture to ensure operational stability and reliability when clamping workpieces.

[0005] To achieve the above objectives, this utility model proposes a novel and efficient plastic part gluing fixture, which includes a base, a housing, an operating shaft, a locking shaft, a first gear, a second gear, a rack, a chuck, a guide post, a first rod, a second rod, and a clamping unit. The clamping unit is arranged opposite to each other and located on the top wall of the housing. The clamping unit includes a connecting block, a rotating arm, a support base, and a pressure arm.

[0006] The base is connected to the bottom of the housing. The operating shaft and the locking shaft are rotatably connected to the side wall of the housing, respectively. The first gear and the second gear are fixedly connected to the operating shaft, and the pawl is fixedly connected to the locking shaft. When the locking shaft rotates, the pawl engages with the second gear to restrict the rotation of the operating shaft and the first gear.

[0007] The rack passes through the top wall of the housing, with its lower part inside the housing and its upper part outside the housing. The lower part of the rack meshes with the first gear. The rack is arranged vertically. The guide post is threaded to the side wall of the housing. The end of the guide post facing the inside of the housing abuts against the outer wall of the rack. The guide post is arranged horizontally.

[0008] The connecting block is fixedly installed on the upper part of the rack. One end of the rotating arm is rotatably connected to the connecting block, and the other end of the rotating arm is rotatably connected to one end of the pressure arm. The other end of the pressure arm is provided with a pressing part. The position between the rotating connection of the rotating arm and the pressure arm and the pressing part is rotatably connected to the support base through a rotating shaft. The support base is fixedly installed on the top wall of the outer shell.

[0009] One end of the first rod is fixedly connected to the rack, the first rods are arranged in parallel, the other end of the first rod is connected to the second rod, the second rod is perpendicular to the first rod, and the top of the second rod is connected to the connecting block in the clamping unit located on the other side.

[0010] Furthermore, the axial direction of the operating shaft is parallel to the axial direction of the locking shaft.

[0011] Furthermore, the first gear, the second gear, and the chuck are located inside the housing.

[0012] Furthermore, the guide post is threadedly connected to the side wall of the housing to adjust the horizontal distance between the end of the guide post and the outer wall of the rack.

[0013] Furthermore, the top wall of the outer casing is used to support the workpiece, and the clamping part is used to clamp the workpiece.

[0014] Compared with related technologies, the novel and efficient plastic parts gluing fixture proposed in this utility model has the following advantages:

[0015] The connection between the base and the outer shell provides stable support for the overall structure. The first and second gears on the operating shaft mesh with the rack to form a gear and rack transmission mechanism. The rack can be driven to move smoothly in the vertical direction by rotating the operating shaft, ensuring the reliability and accuracy of power transmission.

[0016] The pawl on the locking shaft engages with the second gear, which can lock the operating shaft after it has been rotated to a predetermined position, preventing the clamping position from shifting due to accidental rotation and ensuring the stability of the workpiece's fixed state.

[0017] The guide post is threaded to the side wall of the housing, and its end abuts against the outer wall of the rack. By adjusting the thread, the horizontal distance between the guide post and the rack can be precisely controlled, thereby guiding and limiting the movement of the rack, preventing the rack from shaking or deviating during movement, and improving the accuracy of the mechanism's operation.

[0018] In the clamping unit, the connecting block, rotating arm, pressure arm and support base form a lever structure. The rotational connection of the rotating arm and pressure arm, in conjunction with the rotating shaft of the support base, can convert the vertical motion of the rack into the downward pressing action of the pressure arm. Through the lever principle, the clamping force is increased, so that the clamping part can firmly clamp the workpiece.

[0019] The clamping units on both sides are connected to the first and second rods, enabling synchronous clamping and ensuring uniform force on both sides of the workpiece. This prevents workpiece deformation or adhesive misalignment caused by uneven force. The top wall of the outer shell supports the workpiece, and the clamping part acts precisely on the workpiece. The entire fixture has a compact structure and is easy to operate, efficiently fixing the workpiece during the adhesive bonding process of plastic parts. It provides stable and reliable support for the adhesive bonding operation, improving adhesive bonding quality and production efficiency. Attached Figure Description

[0021] Figure 2 This is a schematic diagram of the structure of a novel and efficient plastic part adhesive tooling according to an embodiment of the present invention. Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] Please see Figures 1-2 As shown, this utility model proposes a novel and efficient plastic part gluing fixture, which includes a base 11, a housing 12, an operating shaft 13, a locking shaft 14, a first gear 21, a second gear 22, a rack 23, a chuck 24, a guide post 25, a first rod 26, a second rod 27, and a clamping unit. The clamping unit is arranged opposite to each other and located on the top wall of the housing 12. The clamping unit includes a connecting block 31, a rotating arm 32, a support base 33, and a pressure arm 34. The top wall of the housing 12 is used to support the workpiece, and the clamping part is used to clamp the workpiece.

[0024] The base 11 is connected to the bottom of the housing 12. The operating shaft 13 and the locking shaft 14 are rotatably connected to the side wall of the housing 12. The axial direction of the operating shaft 13 is parallel to the axial direction of the locking shaft 14. The first gear 21 and the second gear 22 are fixedly connected to the operating shaft 13. The pawl 24 is fixedly connected to the locking shaft 14. When the locking shaft 14 rotates, the pawl 24 engages with the second gear 22 to restrict the rotation of the operating shaft 13 and the first gear 21. The first gear 21, the second gear 22, and the pawl 24 are located inside the housing 12.

[0025] The rack 23 passes through the top wall of the outer casing 12, with the lower part of the rack 23 located inside the outer casing 12 and the upper part of the rack 23 located outside the outer casing 12. The lower part of the rack 23 meshes with the first gear 21, and the rack 23 is arranged in a vertical direction.

[0026] The guide post 25 is threaded to the side wall of the housing 12. The end of the guide post 25 facing the inside of the housing 12 abuts against the outer wall of the rack 23. The guide post 25 is arranged in the horizontal direction. The guide post 25 is threaded to the side wall of the housing 12 to adjust the distance in the horizontal direction between the end of the guide post 25 and the outer wall of the rack 23.

[0027] The guide post 25 is threaded to the side wall of the housing 12, and its end facing the inside of the housing 12 abuts against the outer wall of the rack 23 and is arranged in a horizontal direction. The purpose of this arrangement is to guide and limit the movement of the rack 23, ensuring that the rack 23 moves smoothly in the vertical direction.

[0028] The guide post 25 is threaded to the side wall of the housing 12, and the distance between its end and the outer wall of the rack 23 in the horizontal direction can be adjusted. When the rack 23 moves up and down driven by the gear on the operating shaft 13, the end of the guide post 25 always remains in contact with the outer wall of the rack 23, thereby limiting the horizontal displacement of the rack 23 and preventing the rack 23 from shaking or deviating during movement.

[0029] The guide post 25 effectively improves the accuracy and stability of the rack 23's movement, thereby ensuring the accuracy of the entire clamping unit's operation. Through precise guidance and limiting, the vertical movement of the rack 23 is made more stable and reliable, ensuring that the clamping part can accurately clamp the workpiece and avoiding clamping position deviations caused by rack 23 offset. This provides a guarantee for the stable fixation of workpieces during plastic part gluing operations, improving the overall working accuracy and reliability of the tooling.

[0030] A connecting block 31 is fixedly installed on the upper part of the rack 23. One end of the rotating arm 32 is rotatably connected to the connecting block 31, and the other end of the rotating arm 32 is rotatably connected to one end of the pressure arm 34. A pressing part is provided on the other end of the pressure arm 34. The position between the rotating connection of the rotating arm 32 and the pressure arm 34 and the pressing part is rotatably connected to the support base 33 through a rotating shaft. The support base 33 is fixedly installed on the top wall of the outer shell 12.

[0031] One end of the first rod 26 is fixedly connected to the rack 23. The first rod 26 is arranged in parallel. The other end of the first rod 26 is connected to the second rod 27. The second rod 27 is perpendicular to the first rod 26. The top of the second rod 27 is connected to the connecting block 31 in the clamping unit located on the other side.

[0032] The rotation of the operating shaft 13 drives the first gear 21 and the second gear 22 on it to rotate synchronously. The first gear 21 meshes with the rack 23, thereby driving the rack 23 to move up and down in the vertical direction. The upper part of the rack 23 is fixedly connected to the connecting block 31. One end of the rotating arm 32 is rotatably connected to the connecting block 31, and the other end is rotatably connected to the pressure arm 34. The other end of the pressure arm 34 is provided with a pressing part. The rotatable connection between the rotating arm 32 and the pressure arm 34 is rotatably connected to the support seat 33 fixed to the top wall of the outer casing 12 through a rotating shaft, forming a lever structure.

[0033] When rack 23 moves upward, connecting block 31 drives rotating arm 32 to move. Rotating arm 32, through leverage, causes pressure arm 34 to rotate around the axis of support base 33, and the pressing part of pressure arm 34 moves downward to press the workpiece. Conversely, when rack 23 moves downward, pressure arm 34 lifts up to release the workpiece. At the same time, the pawl 24 on locking shaft 14 can engage with second gear 22, restricting the rotation of operating shaft 13 after it rotates to a predetermined position, ensuring a stable pressing state.

[0034] In addition, the clamping units on both sides are connected to the vertical second rod 27 via the first rod 26. When the rack 23 on one side moves, it drives the connecting block 31 on the other side to move synchronously through the rod, so as to realize the synchronous action of the clamping units on both sides, so that the workpiece is subjected to uniform force on both sides, and to ensure the stability and reliability of clamping.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
