Description

Technical Field

[0001] The present invention relates to the field of repair fixtures, in particular to a tool fixture for repairing an injection molding machine base based on a repair material. Background Art

[0002] The base of an injection molding machine usually consists of legs and a table. The legs serve as the core load-bearing structure, bearing the dynamic loads and vibrations during equipment operation for a long time. During continuous use, the key stress-bearing areas of the legs are prone to cracks due to metal fatigue. If not repaired in time, the cracks will accelerate and cause the base structure to fail, seriously affecting the accuracy and safety of the equipment.

[0003] The current mainstream repair process is divided into two steps. First, the repair agent is manually applied to the crack location, and then a mechanical clamp is used to apply extrusion pressure in a direction perpendicular to the crack to allow the repair agent to penetrate the crack and solidify. The core of this process is to ensure that the repair agent fully fills the inside of the crack to avoid residual gaps forming stress concentration points. To improve the filling effect, the clamps need to be tightened step by step from the middle of the crack to both ends during operation, simulating the "suturing" effect to push the repair agent deep into the crack, ultimately achieving dense filling and reliable bonding.

[0004] However, traditional repair fixtures only provide mechanical clamping force and cannot actively replenish repair agents deep into the cracks. Relying on manual pre-coating of repair agents makes it difficult to ensure that the repair agents are fully filled inside narrow cracks, especially for deep and long cracks, which has limited effect. Secondly, the clamping process requires manual adjustment of the locking force of multiple fixtures in sequence. The steps are cumbersome and rely on the operator's experience. It is difficult to ensure that the clamping force applied by each fixture is uniform, which can easily lead to local extrusion of repair agents or insufficient pressure. At the same time, it is impossible to achieve synchronous two-way clamping, that is, to apply pressure from the middle of the crack to both sides simultaneously, which reduces the process controllability and efficiency of "suture-type" extrusion. Summary of the Invention

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a tooling fixture for repairing the base of an injection molding machine based on a repair material, comprising a U-shaped frame, a movable plate is provided on the right side of the U-shaped frame for sliding left and right through a guide column, two support plate frames are fixedly installed on the right side of the U-shaped frame and arranged symmetrically up and down, a linkage plate located on the right side of the movable plate is rotatably arranged between the two support plate frames, and a feeding mechanism for replenishing the repair agent into the cracks and a locking mechanism that gradually applies extrusion force from the middle to the outside are jointly provided on the support plate frame and the linkage plate.

[0006] The feeding mechanism includes a rotating cover rotatably arranged on the left side of the movable plate, a pushing plate matching the shape of the inner side of the rotating cover is arranged on the inner side of the rotating cover for sliding left and right, and a collecting assembly for centrally pushing the repair agent is arranged inside the pushing plate.

[0007] The locking mechanism includes a plurality of threaded columns arranged on the linkage plate through a linkage assembly. The plurality of threaded columns are arranged in a cross shape, and the threaded columns distributed outward from the middle gradually move to the right.

[0008] Preferably, the left side of the U-shaped frame is provided with two abutment plates symmetrically arranged up and down for sliding left and right, and the left sides of the two abutment plates are fixedly installed with an X-shaped frame through a connecting column, and the left side of the U-shaped frame is rotatably connected to an adjusting screw threadedly connected to the X-shaped frame.

[0009] Preferably, the collecting assembly includes a rectangular groove opened in the middle of the pushing plate, a pushing block is provided inside the rectangular groove of the pushing plate for sliding left and right, and extension plates are hinged on the front and rear sides of the pushing block.

[0010] Preferably, two waist-shaped grooves are arranged symmetrically front to back on the upper and lower inner walls of the rectangular groove of the pusher plate, and raised columns are fixedly installed on the upper and lower side surfaces of the extension plate, and the notches of the raised columns are fitted and connected to the corresponding waist-shaped grooves.

[0011] Preferably, a plurality of material guiding square holes are provided on the pushing block along its length direction, and a baffle is hinged on the upper side wall of the material guiding square holes of the pushing block.

[0012] Preferably, a dome column is provided on the lower side wall of the pushing block material guide square hole for sliding along the length direction of the pushing block, a return spring is provided between the dome column and the pushing block, and a limiting plate is fixedly installed on the right end of the lower side wall of the pushing block material guide square hole.

[0013] Preferably, a feed pipe is fixedly installed on the right side of the pushing block, the right end of the feed pipe is rotatably connected to the left end of the middle threaded column, and a flow channel for the repair agent to flow is opened inside the feed pipe.

[0014] Preferably, four sliding rods are fixedly installed on the left side of the linkage plate and are arranged at equal intervals around the middle threaded column. The sliding rods slide left and right and are inserted into the interior of the rotating cover. Except for the middle one, the left ends of the threaded columns arranged up and down are fixedly installed with extrusion plates.

[0015] Preferably, the linkage assembly includes a cross plate fixedly mounted on the right side of the linkage plate, a plurality of square guide columns fixedly mounted on the left side of the cross plate and connected to the threaded columns for left and right sliding, and a plurality of rotating rings threadedly connected to the threaded columns are rotatably arranged on the linkage plate.

[0016] Preferably, a torque coupling is fixedly installed on the right side of the rotating ring, and a pulley is fixedly installed on the right side of the torque coupling. A No. 1 synchronous belt is wound around the outer sides of the upper and lower pulleys, and a No. 2 synchronous belt is wound around the outer sides of the front and rear pulleys.

[0017] The beneficial effects of the present invention are: 1. The present invention adopts a push plate in the feeding mechanism to temporarily store the repair agent, and by driving the push plate to slide to the left on the inner side of the rotating cover, the repair agent temporarily stored inside the push plate is pushed directly into the crack. When the push plate continues to move to the left, its end face exerts an extrusion force on the repair agent, forcing the repair agent to penetrate into the narrow gap of the crack, effectively filling the deep crack, and avoiding the problem of insufficient filling caused by manual application as much as possible.

[0018] 2. The present invention adopts the synergistic effect of the pushing block and the extension plate in the aggregate assembly. When the pushing block moves to the right, the repair agent passes through the pushing block and is gathered into the V-shaped cavity formed by the pushing block and the expanded extension plate. Then the pushing block moves to the left, and the repair agent is directionally squeezed into the core area of ​​the crack, further significantly improving the deep filling efficiency and effectively avoiding manual feeding operations.

[0019] 3. The present invention adopts the linkage assembly of the locking mechanism to drive the cross-arranged threaded columns to move synchronously, and applies extrusion force to the legs in turn through the threaded columns with different initial positions, thereby realizing progressive locking from the middle threaded column to the outer threaded column, thereby completing the "suture-type" extrusion in one go, replacing the traditional manual tightening steps in sequence, and ensuring that the extrusion force is evenly expanded from the middle of the crack to both ends.

[0020] 4. The present invention uses a pulley in the locking mechanism to drive the threaded column to move through the torque coupling and the rotating ring. The torque coupling automatically disconnects the torque transmission after the threaded column reaches the preset clamping force, so that the extrusion force applied to the support leg by all threaded columns remains consistent, effectively solving the problem of uneven clamping force caused by manual adjustment.

[0031] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0032] See Figure 1 A tooling fixture for repairing the base of an injection molding machine based on repair materials includes a U-shaped frame 1. A movable plate 3 is provided on the right side of the U-shaped frame 1 for sliding left and right through a guide column 2. Two support plate frames 4 symmetrically arranged up and down are fixedly installed on the right side of the U-shaped frame 1. A linkage plate 5 located on the right side of the movable plate 3 is rotatably provided between the two support plate frames 4. A feeding mechanism 6 for replenishing the repair agent into the crack and a locking mechanism 7 that gradually applies extrusion force from the middle to the outside are jointly provided on the support plate frame 4 and the linkage plate 5.

[0033] When it is necessary to repair the cracks on the base legs, the operator first manually applies the repair agent to the position of the crack, and then the operator adds the repair agent to the inside of the feeding mechanism 6. Then the operator moves the U-shaped frame 1 to the outside of the leg and aligns the feeding mechanism 6 to the position of the crack. The U-shaped frame 1 is then fixed to the leg. The repair agent inside it is actively pressurized into the inside of the crack through the feeding mechanism 6 to increase the filling degree of the repair agent inside the crack. Then, the locking mechanism 7 applies extrusion force along the middle of the crack to both ends to seal the repair agent inside the crack, and at the same time, the repair agent is tightly fitted to the leg to improve the bonding strength and density.

[0034] See Figure 1 、 Figure 3 and Figure 4 The feeding mechanism 6 includes a rotating cover 61 rotatably arranged on the left side of the movable plate 3. A pushing plate 62 matching the shape of the inner side of the rotating cover 61 is arranged on the inside of the rotating cover 61 for sliding left and right. A collecting assembly 63 for centrally pushing the repair agent is arranged inside the pushing plate 62.

[0035] See Figure 1 、 Figure 3 、 Figure 6 and Figure 7 The locking mechanism 7 includes a plurality of threaded columns 72 arranged on the linkage plate 5 through a linkage assembly 71. The plurality of threaded columns 72 are arranged in a cross shape, and the threaded columns 72 distributed from the middle to the outside gradually shift to the right.

[0036] See Figure 3 and Figure 4 The collecting assembly 63 includes a rectangular groove opened in the middle of the pushing plate 62. A pushing block 631 is provided inside the rectangular groove of the pushing plate 62 for sliding left and right. The front and rear sides of the pushing block 631 are hinged with an extension plate 632.

[0037] See Figure 3 、 Figure 5 and Figure 6 A feeding pipe 64 is fixedly installed on the right side of the pushing block 631. The right end of the feeding pipe 64 is rotatably connected to the left end of the middle threaded column 72. A flow channel for the repair agent to flow is opened inside the feeding pipe 64.

[0038] It should be noted that the right part of the flow channel inside the feed pipe 64 is a straight line structure arranged along the radial direction of the feed pipe 64, the middle part of the flow channel inside the feed pipe 64 is a straight line structure arranged along the axis of the feed pipe 64, and the left part of the flow channel inside the feed pipe 64 is a plurality of straight line structures arranged at equal intervals along the circumference of the feed pipe 64. The right part of the flow channel is the feed port, and the feed port of the flow channel is closed by screws.

[0039] In the initial state, see Figure 4The left side of the pushing block 631 is flush with the left side of the pushing plate 62, so that the pushing plate 62 pushes the two extension plates 632 to rotate, and then the left sides of the two extension plates 632 are flush with the left side of the pushing plate 62, and at this time the space formed between the pushing block 631, the right side of the extension plate 632 and the rectangular groove of the pushing plate 62 is used to temporarily store the repair agent.

[0040] When it is necessary to repair the cracks in the base legs, the operator injects the repair agent into the feed port of the flow channel of the feed pipe 64 through a syringe or a manual pump, so that the repair agent moves along the flow channel of the feed pipe 64 and fills the inside of the rectangular groove of the push plate 62, so that the repair agent is located between the push block 631, the right part of the extension plate 632 and the left side wall of the rectangular groove of the push plate 62.

[0041] See Figure 4 and Figure 5 A plurality of material guiding square holes are provided on the pushing block 631 along its length direction, and a baffle 633 is hinged on the upper side wall of the material guiding square hole of the pushing block 631.

[0042] See Figure 4 and Figure 5 A dome column 634 is provided on the lower side wall of the material guiding square hole of the pushing block 631 so as to slide along the length direction of the pushing block 631. A return spring is provided between the dome column 634 and the pushing block 631. A limiting plate 635 is fixedly installed on the right end of the lower side wall of the material guiding square hole of the pushing block 631.

[0043] In the initial state, the return spring pushes the dome column 634 upward by its own elastic force, so that the dome structure on the upper part of the dome column 634 blocks the lower left part of the baffle 633, so that in the initial state, the baffle 633 closes the material guide square hole, preventing the repair agent temporarily stored in the rectangular groove of the push plate 62 from moving directly through the material guide square hole to the left part of the push block 631.

[0044] It should be noted that the repair agent used in this embodiment is in the form of a viscous paste with a certain fluidity. Therefore, the baffle 633 does not need to completely seal the material guide square hole, and the pushing block 631 and the extension plate 632 do not need to completely seal and block the left part of the rectangular groove of the push plate 62. It can also prevent the repair agent from flowing quickly to the outside of the push plate 62.

[0045] See Figure 1 and Figure 2 The left side of the U-shaped frame 1 is provided with two symmetrically arranged abutment plates 11 for sliding left and right. The left sides of the two abutment plates 11 are fixedly installed with an X-shaped frame 13 through a connecting column 12. The left side of the U-shaped frame 1 is rotatably connected to an adjusting screw 14 threadedly connected to the X-shaped frame 13.

[0046] When the operator manually applies the repair agent to the position of the crack, the operator manually passes the U-shaped frame 1 through the outside of the leg with the crack, and makes the rotating cover 61 correspond to the position of the crack. Then the operator manually rotates the rotating cover 61, and at the same time makes the middle threaded column 72 correspond to the middle of the crack, so that the inclination direction of the middle of the rotating cover 61 roughly corresponds to the direction of the crack. Then the operator manually turns the adjusting screw 14, so that the adjusting screw 14 drives the two abutment plates 11 to move synchronously to the right through the X-shaped frame 13 until they abut against the side of the leg.

[0047] When the two abutment plates 11 abut against the side surfaces of the supporting legs, the adjusting screw 14 continues to be rotated. Since the abutment plates 11 are blocked by the supporting legs and cannot move, the adjusting screw 14 drives the U-shaped frame 1 to move to the left until the right side of the U-shaped frame 1 abuts against the side surfaces of the supporting legs. Thus, the U-shaped frame 1 is locked on the supporting legs by the clamping of the supporting legs by the right side of the U-shaped frame 1 and the abutment plates 11.

[0048] It should be noted that the diameter of the right end of the guide column 2 is larger than that of its left end, and a countersunk groove for the right end of the guide column 2 to enter is provided on the right side surface of the movable plate 3. When the U-shaped frame 1 is locked on the support leg, the U-shaped frame 1 drives the right end of the guide column 2 to move completely to the inside of the countersunk groove, and the guide column 2 drives the left side of the rotating cover 61 to fit on the side of the support leg by pushing the movable plate 3.

[0049] See Figure 1 、 Figure 3 、 Figure 6 and Figure 7 The linkage assembly 71 includes a cross plate 711 fixedly installed on the right side of the linkage plate 5, and a plurality of square guide columns 712 are fixedly installed on the left side of the cross plate 711 and are connected to the threaded columns 72 for left and right sliding. A plurality of rotating rings 713 are rotatably provided on the linkage plate 5 and are threadedly connected to the threaded columns 72.

[0050] See Figure 6 and Figure 7 A torque coupling 714 is fixedly installed on the right side of the rotating ring 713, and a pulley 715 is fixedly installed on the right side of the torque coupling 714. A No. 1 synchronous belt is wound around the outer sides of the upper and lower pulleys 715, and a No. 2 synchronous belt is wound around the outer sides of the front and rear pulleys 715.

[0051] It should be noted that a nut is fixedly installed on the right side of any pulley 715, and the right side of the square guide column 712 is a columnar structure for blocking the threaded column 72, and the columnar structure of the square guide column 712 gradually shortens from the middle to the outside. In the initial state, there is a gap between the right end of all the threaded columns 72 and the columnar structure of the corresponding square guide column 712.

[0052] It should be noted that the torque coupling 714 in this embodiment adopts the friction torque limiting coupling in the prior art, so that the torque coupling 714 can release the torque transmission by relative sliding between the friction plates when the torque is overloaded, and automatically restore the torque transmission when the torque returns to the rated value.

[0053] When the left side of the rotating cover 61 is fitted against the side of the support leg, the operator drives the pulley 715 at the corresponding position to rotate by manually reversing the nut. The pulley 715 drives all the pulleys 715 to rotate synchronously through the No. 1 synchronous belt and the No. 2 synchronous belt, so that the pulley 715 drives the rotating ring 713 to rotate through the torque coupling 714, and the rotating ring 713 drives the corresponding threaded column 72 to move to the right along the square guide column 712, so that all the threaded columns 72 move to their right ends against the columnar structure of the corresponding square guide column 712, thereby initializing and correcting the positions of all the threaded columns 72 to ensure that the threaded columns 72 can squeeze the support legs one by one.

[0054] See Figure 4 、 Figure 6 and Figure 8 Two waist-shaped grooves are arranged symmetrically front and back on the upper and lower inner walls of the rectangular groove of the push plate 62. Protruding columns are fixedly installed on the upper and lower sides of the extension plate 632, and the notches of the protruding columns are connected to the corresponding waist-shaped grooves.

[0055] When the threaded column 72 in the middle moves to the right, the threaded column 72 in the middle drives the feeding tube 64 to move synchronously, and the feeding tube 64 pulls the pushing block 631 to move to the right. At the same time, the pushing block 631 drives the two extension plates 632 to move synchronously close to one end of the pushing block 631 itself, and the two extension plates 632 drive the raised columns thereon to move along the corresponding waist-shaped grooves toward the direction close to the pushing block 631, so that the pushing block 631 and the extension plate 632 gradually form a V-shaped structure with the opening facing left.

[0056] When the pushing block 631 and the extension plate 632 move to the left, the pushing block 631 and the extension plate 632 jointly compress the repair agent in the pushing plate 62, so that the compressed repair agent pushes the baffle 633, and the lower part of the baffle 633 pushes the dome structure of the dome column 634, driving the dome column 634 to move downward until it shrinks inside the pushing plate 62, and then the repair agent pushes the baffle 633 to flip, so that the baffle 633 can no longer block the repair agent, and the repair agent moves along the material guide square hole on the pushing block 631 to the left part of the pushing block 631, and moves to the inside of the opening of the V-shaped structure formed by the pushing block 631 and the extension plate 632, thereby gathering the repair agent.

[0057] The operator then rotates the pulley 715 forward, causing all the threaded columns 72 to move to the left synchronously. The middle threaded column 72 pushes the pushing block 631 to move to the initial state, so that the pushing block 631 and the extension plate 632 jointly push the repair agent on its left side to the inside of the crack, thereby actively pressing the repair agent into the inside of the crack to ensure the filling degree of the repair agent inside the crack.

[0058] It should be noted that two notched grooves arranged vertically are provided on the left side of the pushing block 631, two blocking plates 621 corresponding to the notched grooves are fixedly installed on the pushing plate 62, two strip grooves arranged front and back are provided on the left side of the pushing plate 62, and two limit bars 622 corresponding to the strip grooves are fixedly installed on the rotating cover 61.

[0059] When the pushing block 631 moves to the left to its initial position, the pushing block 631 drives the notch groove on it to move to the outside of the corresponding blocking plate 621, so that the pushing block 631 pushes the blocking plate 621 through the notch groove, and the blocking plate 621 drives the pushing plate 62 to move to the left synchronously, and continues to squeeze the repair agent into the crack. When the crack is full of the repair agent, the repair agent moves out to its outside through the edge of the rotating cover 61.

[0060] Then continue to move the pushing block 631 so that the bar groove of the pushing plate 62 moves to the outside of the corresponding limit bar 622. Then the pushing plate 62 drives the rotating cover 61 to press against the support leg by pushing the limit bar 622, thereby sealing the repair agent inside the crack. At this time, the middle threaded column 72 directly applies extrusion force to the middle of the crack through the feeding tube 64 and the pushing block 631.

[0061] It should be noted that since the connection between the pushing block 631 and the extension plate 632 is not sealed, the excess repair agent can slowly seep to the right into the rectangular groove of the pushing plate 62 under the action of the extrusion force, ensuring that the pushing block 631 and the extension plate 632 can be tightly attached to the side of the support leg when the crack is squeezed.

[0062] See Figure 6 Four sliding rods 51 are fixedly installed on the left side of the linkage plate 5 and are arranged at equal intervals around the middle threaded column 72. The sliding rods 51 slide left and right and are inserted into the interior of the rotating cover 61. Except for the middle part, the left ends of the threaded columns 72 arranged up and down are fixedly installed with extrusion plates 721.

[0063] When the rotating cover 61 is rotated, the rotating cover 61 drives the linkage plate 5 to rotate synchronously through the sliding rod 51, so that the linkage plate 5 drives the threaded columns 72 to rotate together, thereby making the threaded columns 72 arranged vertically or horizontally arranged roughly along the direction of the crack.

[0064] After the threaded column 72 in the middle squeezes the middle part of the crack, the pulley 715 continues to rotate forward, so that the threaded column 72 in the middle increases the squeezing pressure on the middle part of the crack. When the squeezing pressure of the threaded column 72 in the middle reaches the preset value, the torque coupling 714 corresponding to the threaded column 72 in the middle disconnects the torsion transmission, and continues to drive the remaining threaded columns 72 to squeeze on the movable plate 3 in order from the middle to the outside. The threaded columns 72 arranged above and below drive the squeezing plates 721 thereon to squeeze on the movable plate 3, so that the movable plate 3 immediately transmits the pressure to the support legs through the rotating cover 61, thereby completing the "suture-type" squeezing at one time, ensuring that the squeezing pressure expands evenly from the middle part of the crack to both ends.

[0065] After that, after the repair agent solidifies, the U-shaped frame 1 is removed from the support leg, and the residual repair liquid on the fixture is cleaned, and then the pulley 715 is reversed so that the right ends of all the threaded columns 72 are against the columnar structure of the corresponding square guide column 712, and then the pulley 715 is rotated forward again, so that the middle threaded column 72 drives the push block 631 to move to the initial position, thereby resetting the threaded column 72 and the push block 631, and then the operator manually pushes the baffle 633 to reset it for reuse.

[0066] See Figures 1 to 8 When repairing cracks on the support legs, the present invention also includes the following steps: In the first step, the operator injects the repair agent into and fills the inside of the rectangular groove of the push plate 62 through a syringe or a manual pump, so that the repair agent is located between the pushing block 631, the right part of the extension plate 632 and the left side wall of the rectangular groove of the push plate 62.

[0067] In the second step, the operator manually passes the U-shaped frame 1 through the outside of the leg with the crack, and then manually rotates the rotating cover 61 to correspond to the direction of the crack, and manually twists the adjusting screw 14, so that the right side of the U-shaped frame 1 and the abutment plate 11 clamp the leg, so that the U-shaped frame 1 is locked on the leg.

[0068] In the third step, the operator manually reverses the nut, and the push block 631 and the extension plate 632 gradually form a V-shaped structure with the opening facing left, and the compressed repair agent moves along the material guide square hole to the inside of the opening of the V-shaped structure formed by the push block 631 and the extension plate 632, thereby gathering the repair agent.

[0069] In the fourth step, the operator rotates the pulley 715 forward so that the pushing block 631 and the stretching plate 632 jointly push the repair agent on its left side into the inside of the crack, thereby actively pressing the repair agent into the inside of the crack to ensure the filling degree of the repair agent inside the crack.

[0070] In the fifth step, the pushing block 631 drives the pushing plate 62 to move to the left, and continues to squeeze the repair agent into the crack. When the crack is full of the repair agent, the repair agent is removed to the outside through the edge of the rotating cover 61. Then the pushing block 631 drives the rotating cover 61 to press against the support leg, thereby sealing the repair agent inside the crack.

[0071] In the sixth step, the pulley 715 continues to rotate forward, so that the middle threaded column 72 increases the extrusion pressure on the middle of the crack to a preset value, and then the remaining threaded columns 72 are squeezed on the movable plate 3 in sequence from the middle to the outside, thereby completing the "suture-type" extrusion at one time, ensuring that the extrusion force expands evenly from the middle of the crack to both ends.

[0072] In the seventh step, after the repair agent is cured, the U-shaped frame 1 is removed from the support leg, and the residual repair liquid on the fixture is cleaned, and then the threaded column 72, the push block 631 and the baffle 633 are manually reset for reuse.
