Description

Technical Field

[0001] This invention relates to the field of electric slide table technology, specifically a high-load electric slide table. Background Technology

[0002] High-load electric slides are powered by motors and converted into linear motion through a transmission mechanism, achieving high-precision and high-speed linear motion. They are particularly good at maintaining high precision and high speed while bearing large loads. Electric slides are widely used in automated production lines, precision machining and other fields. Their main function is to improve production efficiency and processing quality, while reducing labor costs and operational risks.

[0003] Patent CN211791091U discloses a high-load slide module, which includes a mounting profile and a lead screw. A base plate is located at the bottom of the mounting profile, and a mounting plate is located at one end of the mounting profile. A motor is mounted on the mounting plate. Two guide rails are provided on the base plate, and sliding profile sections are provided on the two guide rails. Sliding slider sections are located on both sides of the sliding profile sections, and the two slider sections are respectively mounted on the two guide rails. A bushing section is located at the bottom of the sliding profile section, and the bushing section is fitted onto the lead screw. A left bearing seat and a right bearing seat are provided on the base plate. An angular contact ball bearing is installed in the left bearing seat, and a deep groove ball bearing is installed in the right bearing seat. One end of the lead screw passes through the angular contact ball bearing in the left bearing seat and connects to the working shaft of the motor, while the other end of the lead screw enters the deep groove ball bearing in the right bearing seat. This patented high-load slide module can bear a larger load by converting the rotational motion of the motor into the linear motion of the sliding components on the lead screw.

[0004] However, the current high-load slide module has the following problems: When the high-load slide module is in use, the weight of the item is easily applied to the transmission rod during the left and right movement of the electric slide, which can easily cause deformation and damage to the transmission rod. As a result, the parts in the equipment will deform and be damaged when the electric slide moves heavy items. Therefore, we have proposed a high-load electric slide. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a high-load electric slide table, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-load electric slide table, comprising a Z-shaped plate, a servo motor fixedly mounted on the top surface of the Z-shaped plate, a spiral frame fixed on the right side of the Z-shaped plate, a sliding groove formed in the middle of the top surface of the spiral frame, two triangular rings fixed at the bottom inside the spiral frame, threaded rods rotatably mounted on the inner walls of the triangular rings, the threaded rods being fixedly connected to the servo motor shaft, a sliding tube slidably mounted on the left side of the outer wall of the threaded rod, the inner wall of the sliding tube engaging with the spiral groove of the threaded rod, and limit grooves formed on both the front and rear sides of the inner wall of the spiral frame, the sliding tube and the spiral frame... The limiting groove is slidably connected. Short columns are fixed on both sides of the top surface of the slide tube. A through hole is opened in the middle of the left side of the short column. The short column is located inside the slide groove of the loop frame. A carrier plate is fixed on the top surface of the short column. The carrier plate is located on the top surface of the loop frame. Two V-shaped frames are fixed on the bottom surface of the slide tube. Rollers are rotatably installed on the bottom of the two V-shaped frames on the side away from each other. The rollers are located at the bottom of the loop frame. Under the action of friction, the rollers roll on the loop frame. When the carrier plate is loaded with heavy items, the weight of the items acts on the rollers, reducing the weight of the threaded rod. A precision control module is provided on the opposite side of the V-shaped frames.

[0007] The precision control module includes a round rod, which is fixed to the bottom of the opposite side of the V-shaped frame. A grooved roller is rotatably mounted on the outer wall of the round rod. The outer wall of the grooved roller has several arc grooves. The grooved roller is located in the middle of the outer wall of the round rod. A convex plate is fixed at the bottom inside the U-shaped frame. Several arc convex strips are provided on the top surface of the convex plate. The arc grooves of the grooved roller and the arc convex strips of the convex plate mesh with each other. The arc grooves of the grooved roller roll onto the arc convex strips of the convex plate, so that the arc convex strips of the convex plate limit the arc grooves of the grooved roller.

[0008] An anti-fall device is installed inside the through hole of the short column, and a lubrication device is installed on the right side of the outer wall of the anti-fall device.

[0009] The Z-shaped plate is located at the bottom left side of the loop frame, the grooved roller is wider than the top surface of the convex strip plate, and the convex strip plate is located between the two triangular rings.

[0010] According to the above technical solution, the anti-fall device includes a U-shaped rod, a ring frame, a vertical plate, and a rubber roller. The U-shaped rod is fixed to the inner wall of the through hole of the short column, the ring frame is fixed to both sides of the outer wall of the U-shaped rod, the vertical plate is fixed to the opposite side of the ring frame, and a groove is provided on the top surface of the vertical plate. The rubber roller is rotatably installed on the inner wall of the groove of the vertical plate, and the front and rear rubber rollers abut against the item to reduce the violent impact of the item during movement.

[0011] According to the above technical solution, the U-shaped rod is located in the middle below the carrier plate, the vertical plate is located on the left and right sides of the carrier plate, two round holes are opened on the side of the two vertical plates away from each other, and the rubber rollers are located on the two sides above the carrier plate.

[0012] According to the above technical solution, the anti-fall device further includes a sliding column, a disc, a spring, and a rubber block. The sliding column is slidably installed inside the circular hole of the vertical plate. The disc is fixed on the surface of the sliding column. The spring is fixed on the opposite side of the disc. The rubber block is fixed on the opposite side of the sliding column. The rubber block tightly abuts against both sides of the item, reducing the shaking of the item and improving the stability of the item when it moves.

[0013] According to the above technical solution, the spring is set on the outer wall of the sliding column, and the end of the spring away from the disc is fixed to the side of the two vertical plates away from each other. The rubber block is located above the top surface of the carrier plate.

[0014] According to the above technical solution, the lubrication device includes a ring, a push rod, a ring plate, an L-shaped plate, a circular shell, and a sponge ring. The ring is slidably installed on the right side of the outer wall of the U-shaped rod. The push rod is fixed in the middle of the front and back sides of the ring. The ring plate is fixed at the end of the push rod away from the ring. The L-shaped plate is fixed at the bottom of the inner side of the U-shaped frame. The circular shell is fixed on the right side of the slide tube. The inner wall of the circular shell has several oil outlet holes. The sponge ring is fixed on the right side of the inner wall of the circular shell. The ring plate is slidably connected to the inner wall of the circular shell. Under the action of extrusion pressure, the sponge ring squeezes out lubricating oil into the oil outlet holes of the circular shell, so that the oil outlet holes of the circular shell evenly coat the threaded rod with lubricating oil.

[0015] According to the above technical solution, the lubrication device further includes a circular block, a short rod, and a second spring. The circular block is fixed to the front and back of the outer wall of the U-shaped rod, and the short rod is fixed to the right side of the circular block. The short rod passes through and slides through the circular ring. The second spring is fixed to the right side of the circular block. Under the elastic force of the second spring, the circular ring moves to the right on the short rod, so that the circular ring can automatically return to its original position, preventing the ring plate from constantly squeezing the sponge ring.

[0016] According to the above technical solution, the L-shaped plate is set inside the right side of the loop frame, the L-shaped plate is on the movement trajectory of the abutment rod, and the end of the spring away from the circular block is fixed to the left side of the ring.

[0017] This invention provides a high-load electric slide table. It has the following advantages:

[0018] (1) The present invention uses a sliding tube, a short column, a carrier plate, a V-shaped frame, rollers, a round rod, and a grooved roller in conjunction with a convex strip plate. The V-shaped frame drives the rollers to move back and forth. Under the action of friction, the rollers roll on the U-shaped frame, so that when the carrier plate is loaded with heavy items, the weight of the items acts on the rollers, reducing the weight of the threaded rod and preventing the parts in the equipment from deforming and causing damage to the equipment during the movement of the electric slide table under the load of heavy items. In addition, during the back and forth movement of the grooved roller, the groove of the grooved roller rolls onto the arc convex strip of the convex strip plate, so that the arc convex strip of the convex strip plate limits the groove of the grooved roller, preventing the accuracy of the carrier plate stopping from decreasing under the action of inertia when the electric slide table is loaded with heavy items.

[0019] (2) By setting up an anti-fall device, the U-shaped rod, ring frame, vertical plate, rubber roller, sliding column, disc and spring cooperate with the rubber block. Under the action of inertia, the item will slide slightly on the carrier plate. The vertical plate prevents the item from tipping over. The item will hit the rubber roller, which will hold the item in place. This reduces the violent collision of the item during movement and prevents the electric slide table from being damaged by the collision when the item is being moved under load. In addition, under the elastic force of the spring, the rubber block is pressed tightly against both sides of the item, which reduces the shaking of the item and improves the stability of the item during movement. This prevents the item from being damaged by violent shaking when the electric slide table is being moved under load.

[0020] (3) The present invention, through the setting of the lubrication device, enables the ring, the push rod, the ring plate, the L-shaped plate, the round shell, the sponge ring, the round block and the short rod to cooperate with the second spring. When the ring plate slides to the left, it contacts the sponge ring. Under the action of the extrusion force, the sponge ring squeezes out the lubricating oil into the oil outlet hole of the round shell, so that the oil outlet hole of the round shell evenly applies the lubricating oil to the threaded rod, preventing the electric slide table from aging too quickly due to lack of maintenance during long-term use. Furthermore, under the elastic force of the second spring, the ring moves to the right on the short rod, so that the ring can automatically return to its original position, preventing the ring plate from constantly squeezing the sponge ring and preventing excessive application of lubricating oil during the use of the electric slide table, thus avoiding waste.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Please see Figures 1-8 One embodiment of the present invention is as follows: a high-load electric slide table includes a Z-shaped plate 1, a servo motor 2 fixedly mounted on the top surface of the Z-shaped plate 1, a spiral frame 3 fixed on the right side of the Z-shaped plate 1, the Z-shaped plate 1 being located at the bottom left side of the spiral frame 3, a sliding groove being formed in the middle of the top surface of the spiral frame 3, two triangular rings 4 fixedly mounted at the bottom inside the spiral frame 3, threaded rods 5 being rotatably mounted on the inner wall of the triangular rings 4, the threaded rods 5 being fixedly connected to the rotating shaft of the servo motor 2, a sliding tube 6 being slidably mounted on the left side of the outer wall of the threaded rod 5, the inner wall of the sliding tube 6 engaging with the spiral groove of the threaded rod 5, and limit grooves being formed on both the front and rear sides of the inner wall of the spiral frame 3, limiting the movement of the sliding tube 6 and the spiral frame 3. The slide tube 6 is connected by a sliding groove. Short columns 9 are fixed on both sides of the top surface of the slide tube 6. A through hole is opened in the middle of the left side of the short column 9. The short column 9 is located inside the slide groove of the loop frame 3. A carrier plate 10 is fixed on the top surface of the short column 9. The carrier plate 10 is located on the top surface of the loop frame 3. Two V-shaped frames 11 are fixed on the bottom surface of the slide tube 6. Rollers 12 are rotatably installed on the bottom of the two V-shaped frames 11 on the side away from each other. The rollers 12 are located at the bottom inside the loop frame 3. When the carrier plate 10 is loaded with heavy items, the weight of the items acts on the rollers 12, reducing the weight of the threaded rod 5 and preventing the parts in the equipment from deforming and causing damage to the equipment during the movement of the electric slide table with heavy items.

[0032] A precision control module is provided on the opposite side of the V-shaped frame 11. The precision control module includes a round rod 13, which is fixed to the bottom of the opposite side of the V-shaped frame 11. A grooved roller 14 is rotatably installed on the outer wall of the round rod 13. The outer wall of the grooved roller 14 has several arc grooves. The grooved roller 14 is located in the middle of the outer wall of the round rod 13. A convex plate 15 is fixed at the bottom inside the U-shaped frame 3. The top surface of the convex plate 15 has several arc convex strips. The arc grooves of the grooved roller 14 and the arc convex strips of the convex plate 15 mesh with each other. The grooved roller 14 is wider than the top surface of the convex plate 15. The convex plate 15 is located between two triangular rings 4. The rubber roller 74 abuts against the item to reduce the violent collision of the item during the movement and to prevent the item from being damaged by collision when the electric slide is moving under load.

[0033] In use, the servo motor 2 on the Z-shaped plate 1 is started, and the shaft of the servo motor 2 begins to rotate in both directions. The servo motor 2 drives the threaded rod 5 to rotate in both directions. The threaded rod 5 rotates in both directions within the triangular ring 4. The loop frame 3 supports the triangular ring 4. Because the weight of the item is easily applied to the transmission rod during the left and right movement of the electric slide, it is easy to cause deformation and damage to the transmission rod. At this time, the threaded rod 5 drives the slide tube 6 to rotate in both directions. The slide tube 6 is restricted by the limiting groove of the loop frame 3, allowing the spiral groove of the threaded rod 5 to drive the slide tube 6 to move left and right. The slide tube 6 moves left and right within the threaded rod 5, and the slide tube 6 drives the short column 9. The short column 9 moves back and forth in the groove of the loop frame 3, which in turn drives the carrier plate 10 to move back and forth. The carrier plate 10 moves back and forth on the loop frame 3. At the same time, the slide tube 6 drives the V-shaped frame 11 to move back and forth, which in turn drives the roller 12 to move back and forth. Under the action of friction, the roller 12 rolls on the loop frame 3. When the carrier plate 10 is loaded with heavy items, the weight of the items is transferred to the roller 12, reducing the load on the threaded rod 5 and preventing the threaded rod 5 from bearing a large load. This avoids the problem of deformation of the parts in the equipment and damage to the equipment during the movement of heavy items on the electric slide table.

[0034] While the slide tube 6 drives the V-shaped frame 11 to move back and forth, the V-shaped frame 11 drives the round rod 13 to move back and forth, and the round rod 13 drives the grooved roller 14 to move back and forth. Under the action of friction, the grooved roller 14 moves back and forth on the convex plate 15 and rotates back and forth on the round rod 13. During the back and forth movement of the grooved roller 14, the arc groove of the grooved roller 14 rolls onto the arc protrusion of the convex plate 15, so that the arc protrusion of the convex plate 15 limits the arc groove of the grooved roller 14, preventing the inertia of the carrier plate 10 from reducing the stopping accuracy when moving heavy objects, thereby avoiding the problem of the decrease in stopping accuracy of the carrier plate 10 under the action of inertia when the electric slide table is loaded with heavy objects.

[0035] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, an anti-fall device 7 is provided inside the through hole of the short column 9. The anti-fall device 7 includes a U-shaped rod 71, a ring frame 72, a vertical plate 73, and a rubber roller 74. The U-shaped rod 71 is fixed to the inner wall of the through hole of the short column 9, the ring frame 72 is fixed to both sides of the outer wall of the U-shaped rod 71, the vertical plate 73 is fixed to the opposite side of the ring frame 72, and a groove is provided on the top surface of the vertical plate 73. The rubber roller 74 is rotatably installed on the inner wall of the groove of the vertical plate 73. The U-shaped rod 71 is located in the middle below the carrier plate 10, the vertical plate 73 is located on the left and right sides of the carrier plate 10, and two round holes are provided on the side of the two vertical plates 73 away from each other. The rubber roller 74 is located on both sides above the carrier plate 10. The rubber roller 74 abuts against the item to reduce the violent collision of the item during the movement and to prevent the item from being damaged by collision when the electric slide is moving with the load.

[0036] The anti-fall device 7 also includes a sliding column 75, a disc 76, a spring 77, and a rubber block 78. The sliding column 75 is slidably installed inside the circular hole of the vertical plate 73. The disc 76 is fixed to the surface of the sliding column 75. The spring 77 is fixed to the opposite side of the disc 76. The rubber block 78 is fixed to the opposite side of the sliding column 75. The spring 77 is set on the outer wall of the sliding column 75. The end of the spring 77 away from the disc 76 is fixed to the side of the two vertical plates 73 away from each other. The rubber block 78 is located above the top surface of the carrier plate 10. The rubber block 78 presses tightly against both sides of the item, reducing the shaking of the item and improving the stability of the item when it moves, thus preventing the electric slide from shaking and damaging the item when it is loaded.

[0037] A lubrication device 8 is provided on the right side of the outer wall of the anti-fall device 7. The lubrication device 8 includes a ring 81, a stop rod 82, a ring plate 83, an L-shaped plate 84, a circular shell 85, and a sponge ring 86. The ring 81 is slidably installed on the right side of the outer wall of the U-shaped rod 71. The stop rod 82 is fixed in the middle of the front and back sides of the ring 81. The ring plate 83 is fixed at the end of the stop rod 82 away from the ring 81. The L-shaped plate 84 is fixed at the bottom of the inner side of the U-shaped frame 3. The circular shell 85 is fixed on the right side of the slide tube 6. The inner wall of the circular shell 85... Several oil outlet holes are provided. The sponge ring 86 is fixed to the right side of the inner wall of the circular shell 85. The ring plate 83 is slidably connected to the inner wall of the circular shell 85. The L-shaped plate 84 is set inside the right side of the loop frame 3. The L-shaped plate 84 is on the movement trajectory of the push rod 82. The sponge ring 86 squeezes out lubricating oil into the oil outlet hole of the circular shell 85, so that the oil outlet hole of the circular shell 85 evenly applies the lubricating oil to the threaded rod 5, avoiding the electric slide table from aging too quickly due to lack of maintenance during long-term use.

[0038] The lubrication device 8 also includes a circular block 87, a short rod 88, and a second spring 89. The circular block 87 is fixed to the front and rear of the outer wall of the U-shaped rod 71, and the short rod 88 is fixed to the right side of the circular block 87. The short rod 88 passes through and is slidably connected to the ring 81. The second spring 89 is fixed to the right side of the circular block 87, and the end of the second spring 89 away from the circular block 87 is fixed to the left side of the ring 81. Under the elastic force of the second spring 89, the ring 81 moves to the right on the short rod 88. The ring 81 can automatically return to its original position, so that the ring plate 83 will not continuously squeeze the sponge ring 86, and avoid excessive lubrication during the use of the electric slide table.

[0039] While the slide tube 6 drives the short column 9 to move back and forth, the short column 9 drives the U-shaped rod 71 to move back and forth, the U-shaped rod 71 drives the ring frame 72 to move back and forth, the ring frame 72 drives the vertical plate 73 to move back and forth, and the vertical plate 73 drives the rubber roller 74 to move back and forth. During the process of the carrier plate 10 moving the item back and forth, the item will slide slightly on the carrier plate 10 due to inertia. The vertical plate 73 prevents the item from tipping over. When the item tipps over the vertical plate 73, it will hit the rubber roller 74, causing the rubber roller 74 to hold the item in place. This reduces the violent collisions that occur during the movement of the item and prevents the equipment from being damaged by collisions when moving the item. This avoids the problem of damage to the item caused by collisions when the electric slide table is carrying an item.

[0040] While the ring frame 72 drives the vertical plate 73 to move back and forth, the vertical plate 73 drives the sliding column 75 to move back and forth, the sliding column 75 drives the disc 76 to move back and forth, the disc 76 drives the spring 77 to move back and forth, and at the same time, the sliding column 75 drives the rubber block 78 to move back and forth. When the item slides on the carrier plate 10 due to inertia, the pushing force generated by the item acts on the rubber block 78, and the rubber block 78 drives the sliding column 75 to move. The sliding column 75 slides in the vertical plate 73, and the sliding column 75 drives the disc 76 to move. The spring 77 on the disc 76 begins to stretch. Under the elastic force of the spring 77, the rubber block 78 is pressed tightly against both sides of the item, reducing the shaking of the item and improving the stability of the item when it moves. This avoids the problem of the electric slide table causing the item to shake violently and be damaged when it is loaded.

[0041] While the short column 9 drives the U-shaped rod 71 to move back and forth, the U-shaped rod 71 drives the ring 81 to move back and forth, the ring 81 drives the abutment rod 82 to move back and forth, and the abutment rod 82 drives the ring plate 83 to move back and forth. When the ring 81 moves to the far right, the abutment rod 82 contacts the L-shaped plate 84. Under the action of the extrusion force, the abutment rod 82 drives the ring 81 to move to the left. The ring 81 slides to the left on the U-shaped rod 71. The abutment rod 82 drives the ring plate 83 to move to the left. The ring plate 83 slides to the left in the circular shell 85. During the sliding of the ring plate 83 to the left, it contacts the sponge ring 86. Under the action of the extrusion force, the sponge ring 86 squeezes out lubricating oil into the oil outlet of the circular shell 85, so that the oil outlet of the circular shell 85 evenly coats the threaded rod 5 with lubricating oil. This prevents the equipment from being neglected during long-term use, thus avoiding the problem of the electric slide table aging too quickly due to lack of maintenance.

[0042] As the ring 81 slides to the left on the U-shaped rod 71, the U-shaped rod 71 supports the circular block 87, which in turn supports the short rod 88. Simultaneously, the ring 81 slides to the left on the short rod 88, and the second spring 89 on the circular block 87 contracts under the force of its elasticity. When the abutment rod 82 leaves the L-shaped plate 84, the ring 81 moves to the right on the short rod 88 under the force of the second spring 89. The ring 81 drives the abutment rod 82 to move to the right, which in turn drives the ring plate 83 to move to the right. The ring plate 83 then leaves the sponge ring 86, allowing the ring 81 to automatically return to its original position. This prevents the ring plate 83 from continuously squeezing the sponge ring 86, thus avoiding the problem of excessive lubrication during the use of the electric slide table.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
