Description

Technical Field

[0001] This utility model relates to the field of electric slide table technology, and in particular to a reciprocating electric slide table. Background Technology

[0002] An electric slide table is a type of linear slide table, often referred to in industry as an electric cylinder or linear module. It consists of a linear slide table and a motor drive. The electric slide table achieves automatic linear motion of the workpiece through motor drive. By combining multiple axes, it forms a motion execution mechanism on the equipment. This mechanism is often called an industrial robot, an XYZ axis robot, or a coordinate axis slide table.

[0003] The currently published patent, CN218760931U, discloses an electric slide table. By setting up a slide table, a buffer frame, a limiting rod, a moving block, a damping spring, a connecting rod, and a buffer plate, the buffer plate and damping spring are used to meet the friction and collision conditions at both ends of the slide table during movement. This avoids the friction and collision that can easily occur at both ends of the slide table due to prolonged linear movement, thus improving the safety of both ends of the slide table during sliding and increasing the utilization rate of the electric slide table.

[0004] Based on the above search results, the electric slide table uses buffer plates and damping springs to meet the situation of friction and collision at both ends during the movement of the slide table. However, the slide table block is guided and positioned by the connecting plates at the bottom. The two connecting plates are in contact with the surface of the slide table frame. When the slide table slides, it will drive the two connecting plates to slide on the surface of the slide table frame. At this time, sliding friction is generated between the connecting plates and the slide table frame, which increases the resistance of the slide table. The sliding contact between the two connecting plates and the slide table frame for limiting and guiding not only leads to greater energy consumption of the equipment, but also reduces the smoothness of the slide table. Utility Model Content

[0005] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a reciprocating electric slide table that can solve the problem of sliding friction between the connecting plate and the slide table frame, which increases the resistance of the slide table sliding. The sliding contact limit and guidance between the two connecting plates and the slide table frame not only leads to greater energy consumption of the equipment, but also reduces the smoothness of the slide table sliding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reciprocating electric slide table, comprising a mounting frame and a slide table guide device; a slide table block is slidably mounted inside the mounting frame, and two mounting holes are provided on the right side of the mounting frame; the slide table guide device comprises two cylindrical blocks, two guide rods, four guide sliders, and ball bearings, the two cylindrical blocks are slidably mounted inside the two mounting holes respectively, the right ends of the two guide rods are fixedly connected to the left ends of the two cylindrical blocks respectively, the four guide sliders are slidably sleeved on the surfaces of the two guide rods respectively, and the four guide sliders are all fixedly connected to the bottom of the slide table block, the guide sliders have an annular groove inside, and the ball bearings are slidably connected in a circular, equidistant manner inside the annular groove, the ball bearings are slidably connected to the surfaces of the guide rods, and the four guide sliders have the same structure.

[0007] Preferably, a reciprocating lead screw is installed inside the slide block, and the reciprocating lead screw is rotatably installed inside the mounting frame.

[0008] Preferably, a drive motor is fixedly mounted on the right end of the mounting bracket, and the output end of the drive motor is fixedly connected to the right end of the reciprocating lead screw.

[0009] Preferably, the left end of the mounting bracket has two positioning holes, and the left ends of the two guide rods are respectively slidably engaged inside the two positioning holes.

[0012] Preferably, the right end of the mounting bracket has two sliding grooves, and each of the two sliding grooves has a pressure rod slidably connected inside. The left ends of the two pressure rods are respectively fixedly connected to the surfaces of two fixed shafts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] Please see Figure 1-4This utility model provides a technical solution: a reciprocating electric slide table, including a mounting frame 1 and a slide table guide device. A slide block 2 is slidably mounted inside the mounting frame 1, and a reciprocating lead screw 3 is mounted inside the slide block 2. The reciprocating lead screw 3 is rotatably mounted inside the mounting frame 1. A drive motor 4 is fixedly mounted on the right end of the mounting frame 1, and the output end of the drive motor 4 is fixedly connected to the right end of the reciprocating lead screw 3. Two mounting holes 5 are provided on the right side of the mounting frame 1. The slide table guide device includes two cylindrical blocks 6, two guide slide rods 7, four guide sliders 9, and ball bearings 11. The two cylindrical blocks 6 are slidably mounted on two mounting holes 5 respectively. Inside the circular hole 5, the right ends of the two guide slide rods 7 are fixedly connected to the left ends of the two cylindrical blocks 6 respectively. The left end of the mounting bracket 1 has two positioning holes 8. The left ends of the two guide slide rods 7 are slidably engaged in the two positioning holes 8 respectively. The four guide sliders 9 are slidably sleeved on the surfaces of the two guide slide rods 7 respectively. The four guide sliders 9 are all fixedly connected to the bottom of the slide block 2. The inside of the guide slider 9 is provided with an annular groove 10. The inside of the annular groove 10 is equidistantly connected with ball bearings 11. The ball bearings 11 are slidably connected to the surface of the guide slide rods 7. The four guide sliders 9 have the same structure.

[0026] When using this electric slide table, after the operator starts the drive motor 4, the output end of the drive motor 4 rotates, which drives the reciprocating screw 3 to rotate. The rotation of the reciprocating screw 3 drives the slide block 2 to slide back and forth. The slide block 2 slides and drives the four guide sliders 9 at the bottom to slide on the surface of the two guide rods 7. At this time, the two guide rods 7 can guide and limit the four guide sliders 9 and the slide block 2, ensuring that the slide block 2 slides horizontally left and right. When the guide sliders 9 slide left and right, they can drive the balls 11 to slide on the surface of the guide rods 7 through the annular grooves 10. At this time, the balls 11 can roll due to the friction between them and the guide rods 7. Since the contact area between the balls 11 and the guide rods 7 is smaller and the friction is smaller, and the balls 11 can roll, the resistance of the guide sliders 9 sliding on the surface of the guide rods 7 is reduced. Through the rolling contact limit guidance between the two guide rods 7 and the balls 11 inside the four guide sliders 9, the resistance of the slide block 2 sliding left and right is reduced, which not only reduces the energy consumption of the equipment, but also improves the smoothness of the slide block 2.

[0027] The mounting bracket 1 has two fixed shafts 12 that are slidably connected inside. The surfaces of the two cylindrical blocks 6 are each provided with a fixed circular hole 13. The upper ends of the two fixed shafts 12 are slidably engaged inside the two fixed circular holes 13. The lower ends of the two fixed shafts 12 are each fixedly connected with a spring 14. The lower ends of the springs 14 are fixedly connected to the inner wall of the mounting bracket 1. The right end of the mounting bracket 1 has two sliding grooves 15. The interior of the two sliding grooves 15 is slidably connected with a pressure rod 16. The left ends of the two pressure rods 16 are respectively fixedly connected to the surfaces of the two fixed shafts 12.

[0028] The operator slides the sliding rod 16 to drive the fixed shaft 12 to slide downwards and compress the spring 14. The spring 14 gives the fixed shaft 12 a reverse elastic force, causing the fixed shaft 12 to slide downwards and disengage from the fixed circular hole 13, thereby releasing the fixing effect on the cylindrical block 6. The operator then slides the guide rod 7 to the right, which in turn moves the cylindrical block 6 to the right and moves it out of the mounting hole 5. The left end of the guide rod 7 slides to the right and moves out of the positioning hole 8. Finally, it gradually slides from the mounting hole 5 to the right and moves out of the mounting bracket 1 to complete the disassembly. When the guide rod 7 is damaged, it is convenient for the operator to replace the guide rod 7, improving the convenience of replacing the guide rod 7.

[0032] Reciprocating screw 3: The reciprocating screw 3 is rotatably installed inside the mounting bracket 1 and threadedly engaged with the slide block 2; when the drive motor 4 drives it to rotate, the helical motion of the screw is used to convert the rotational motion into the linear reciprocating motion of the slide block 2, which is the core component of the power transmission for the movement of the slide block 2.

[0033] Drive motor 4: Drive motor 4 is fixedly installed on the right end of mounting bracket 1, and its output end is fixedly connected to the right end of reciprocating lead screw 3, providing a power source for the rotation of reciprocating lead screw 3, thereby driving slide block 2 to reciprocate.

[0038] Guide slider 9: There are four guide sliders 9. The four guide sliders 9 are slidably sleeved on the surfaces of the two guide rods 7, and are all fixedly connected to the bottom of the slide block 2. When the slide block 2 moves, it slides along the guide rods 7, which serves to connect the slide block 2 and the guide rods 7. At the same time, its internal structure cooperates with the ball bearings 11 to reduce the sliding resistance.

[0039] Annular groove 10: The annular groove 10 is formed inside the guide slider 9 and is used to install the ball 11, so that the ball 11 can slide along the surface of the guide rod 7 in the annular groove 10, thereby changing the contact mode between the guide slider 9 and the guide rod 7 and reducing friction.

[0041] Fixed shaft 12: There are two fixed shafts 12. Both fixed shafts 12 are slidably connected inside the mounting bracket 1. The upper ends are slidably engaged in the fixing holes 13 on the surface of the two cylindrical blocks 6, and the lower ends are connected to springs 14. By cooperating with the fixing holes 13, the cylindrical blocks 6 are fixed, thereby fixing the position of the guide slide rod 7. When disassembling the guide slide rod 7, it can be released from the fixing holes 13 by pressing down.

[0042] Fixed circular hole 13: Fixed circular hole 13 is formed on the surface of the two cylindrical blocks 6 and is used to cooperate with the upper end of the fixed shaft 12 to realize the connection and positioning of the cylindrical block 6 and the fixed shaft 12, thereby fixing the guide slide rod 7;

[0043] Spring 14: The lower end of spring 14 is fixedly connected to the inner wall of mounting bracket 1, and the upper end is connected to fixed shaft 12. When fixed shaft 12 is pressed down by external force, spring 14 is compressed and stores elastic potential energy. When the external force disappears, spring 14 gives fixed shaft 12 a reverse elastic force, so that it returns to its initial position, assisting fixed shaft 12 in fixing cylindrical block 6.

[0044] Slide 15: There are two slides 15, both of which are opened at the right end of the mounting bracket 1, and the pressure rod 16 is slidably connected inside, providing a track for the sliding of the pressure rod 16;
