Description

Technical Field

[0001] The present invention relates to the technical field of new energy automobile casting, and in particular to a zinc ingot precise feeding and clamping device and a feeding method. Background Art

[0002] Zinc ingots are divided into pure zinc and zinc alloys. Zinc alloys are widely used in the field of industrial manufacturing, such as casting chassis parts for new energy vehicles. In the process of automobile chassis die-casting, the zinc ingots need to be transported to the die-casting position and punched into the required products by the die-casting mechanism. When feeding the zinc ingot raw materials, if the zinc ingots are directly pushed along the work surface to the die-casting position, the zinc ingots are prone to wear in the process of sliding along the work surface, thereby affecting the product precision of automobile chassis parts.

[0003] To solve this problem, the existing zinc ingot feeding device adopts the solution of first clamping the zinc ingot, then moving it away from the work surface, and finally placing it in the die-casting position. However, this brings new problems: the zinc ingot needs to be placed in the clamping mechanism first, then fixed, then the clamping mechanism is driven to move to the die-casting position, and finally the zinc ingot is put down. At the same time, when the zinc ingot is put down, it is also necessary to align it with the die-casting position to prevent the zinc ingot from colliding with the work surface when it falls and not falling accurately to the die-casting position. These problems make the working process more cumbersome and affect the processing efficiency of automobile chassis parts.

[0004] In view of this, we propose a zinc ingot precise feeding clamping device and feeding method to improve the deficiencies in the prior art. Summary of the invention

[0015] As a further improvement of the present technical solution, the positioning mechanism includes a limiting groove fixedly connected to the top of the processing table, a positioning rod is slidably connected in the limiting groove, the positioning rod and the positioning cap are located on the same horizontal line, a sliding rod is fixedly connected to the bottom of the positioning rod, one end of the sliding rod away from the positioning rod is slidably connected to the side wall of the limiting groove, and a second spring is sleeved on the periphery of the sliding rod between the positioning rod and the inner wall of the limiting groove.

[0016] The second object of the present invention is to provide a feeding method for a zinc ingot precision feeding and clamping device, comprising the following steps:

[0017] S1. Place multiple zinc ingot raw materials in the loading trough, and push the zinc ingot at the bottom to slide on the top of the roller group until the zinc ingot at the bottom is moved between the two positioning mechanisms;

[0018] S2, start the lifting mechanism to move downward, when the driving clamping mechanism is connected to the positioning mechanism, the two positioning mechanisms respectively drive the two clamping mechanisms to move away from each other until the zinc ingot is placed between the two clamping mechanisms, and the lifting mechanism moves upward, when the driving clamping mechanism is disconnected from the positioning mechanism, the two positioning mechanisms respectively drive the two clamping mechanisms to move closer to each other to clamp the zinc ingot;

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In the zinc ingot precise feeding and clamping device, during the clamping stage: the two positioning mechanisms are pushed outward by the downwardly moving arc-shaped push plate, and the positioning mechanism then pulls the clamping mechanism sleeved on the top of itself to expand outward synchronously. In addition, the clamping mechanism sleeved on the top of the positioning mechanism can also ensure that the clamping mechanism can be accurately positioned directly above the zinc ingot when clamping the material. During the discharge stage: the arc-shaped push plate that moves downward again pushes the positioning mechanisms on both sides of the die-casting tank to expand outward. On the one hand, it can be accurately positioned directly above the die-casting tank before the zinc ingot is discharged. On the other hand, when the zinc ingot begins to slide into the die-casting tank, the height of the zinc ingot at this time has been reduced by a considerable distance compared to the height when it moves along the slide rail, so it can avoid the position of the zinc ingot falling into the die-casting tank being offset due to the initial height of the zinc ingot being too high when it falls.

[0040] Embodiment 1: In order to prevent the zinc ingot from being worn due to friction between the zinc ingot and the table surface of the processing table 120 during the feeding process, the present invention adopts the following steps: first clamp the zinc ingot, then drive the zinc ingot upward away from the processing table 120, then move it toward the die casting tank 140, and finally make the zinc ingot gradually slide into the die casting tank 140 to ensure the accuracy of the feeding process. Figure 1-Figure 3 As shown, one of the purposes of this embodiment is to provide a zinc ingot precise feeding and clamping device, including a mounting mechanism 100, the mounting mechanism 100 includes a base 110, a processing table 120 is provided on the top of the base 110, a roller group 130 is provided at one end of the top of the processing table 120, a die-casting groove 140 is opened at one end of the top of the processing table 120 away from the roller group 130, driving mechanisms 200 are provided on both sides of the top of the processing table 120 away from each other, a lifting mechanism 300 is fixedly connected between the two driving mechanisms 200, and clamping mechanisms 400 are provided on both sides of the bottom of the lifting mechanism 300 away from each other, and a pair of positioning mechanisms 500 are provided on both sides of the die-casting groove 140 and the roller group 130;

[0041] The roller group 130 is used to drive the zinc ingot located above it to move between the two positioning mechanisms 500;

[0042] The lifting mechanism 300 moves downward to drive the clamping mechanism 400 to connect with the positioning mechanism 500, and the two positioning mechanisms 500 respectively drive the two clamping mechanisms 400 to move away from each other;

[0043] When the lifting mechanism 300 moves upward to drive the clamping mechanism 400 to disconnect from the positioning mechanism 500, the two positioning mechanisms 500 respectively drive the two clamping mechanisms 400 to move closer to each other to clamp the zinc ingot.

[0044] Working principle: First, multiple zinc ingot raw materials are placed in the feeding trough 150, and the zinc ingot at the bottom is pushed to slide on the top of the roller group 130 until the zinc ingot at the bottom is moved between the two positioning mechanisms 500. At this time, the remaining zinc ingot raw materials in the feeding trough 150 slide down to the top of the roller group 130 under the action of their own gravity;

[0045] Next, the lifting mechanism 300 is started to move downward, and when the clamping mechanism 400 is driven to connect with the positioning mechanism 500, the two positioning mechanisms 500 respectively drive the two clamping mechanisms 400 to move away from each other until the zinc ingot is placed between the two clamping mechanisms 400, and the lifting mechanism 300 moves upward, and when the clamping mechanism 400 is driven to disconnect with the positioning mechanism 500, the two positioning mechanisms 500 respectively drive the two clamping mechanisms 400 to move closer to each other to clamp the zinc ingot;

[0046] Then, the driving mechanism 200 is started to drive the two clamping mechanisms 400 clamping the zinc ingot to move toward the die-casting tank 140. After the lifting mechanism 300 is located directly above the die-casting tank 140, the lifting mechanism 300 is started to drive the two clamping mechanisms 400 clamping the zinc ingot to approach the die-casting tank 140 below. After the two clamping mechanisms 400 are respectively in contact with the positioning mechanisms 500 on both sides of the die-casting tank 140, the lifting mechanism 300 drives the two clamping mechanisms 400 and the two positioning mechanisms 500 to move away from each other, so that the zinc ingot gradually slides into the die-casting tank 140, and the die-casting machine 160 performs die-casting on the zinc ingot falling into the die-casting tank 140.

[0047] Finally, the driving mechanism 200 is started again to drive the lifting mechanism 300 back to the top of the roller group 130, and the above steps are repeated.

[0048] In order to ensure that the zinc ingot is not subjected to friction with the processing table 120 during the feeding process, which may cause the accuracy of the final product to be damaged, a lifting mechanism 300 is provided to clamp the zinc ingot raw material to be die-cast and keep it away from the surface of the processing table 120 .

[0049] like Figure 4 and Figure 5 As shown, a feeding trough 150 is provided on the top of the roller group 130, and a die-casting machine 160 is provided above the die-casting trough 140. The main components of the die-casting machine 160 are: a hydraulic press fixedly arranged above the die-casting trough 140 and a die fixedly connected to the movable lifting end of the hydraulic press, and the punch of the die is adapted to the die-casting trough 140; the lifting mechanism 300 includes a mounting frame 310 fixedly connected between two slide seats 220, a hydraulic rod 320 is provided on the mounting frame 310, the mounting frame 310 is fixedly connected to the fixed part of the hydraulic rod 320, a U-shaped seat 330 is provided at the bottom of the hydraulic rod 320, the top of the U-shaped seat 330 is fixedly connected to the movable part of the hydraulic rod 320, and a plurality of guide rods 340 are fixedly connected to the top of the U-shaped seat 330, and each guide rod 340 is slidably connected to the mounting frame 310.

[0050] The improvement lies in that: when the zinc ingot raw material slides along the roller group 130 to the bottom of the inverted U-shaped seat 330, the hydraulic rod 320 is started, which drives the U-shaped seat 330 to approach the zinc ingot below through its own movable end. In the process of the U-shaped seat 330 approaching the zinc ingot, the two clamping mechanisms 400 are respectively connected with the corresponding positioning mechanisms 500. Next, the two positioning mechanisms 500 are separated from each other first, and then the two clamping mechanisms 400 are pulled by the positioning mechanisms 500 connected to themselves, and gradually move away from each other until the zinc ingot below the U-shaped seat 330 is completely placed between the two clamping mechanisms 400.

[0051] In order to ensure the stability of the zinc ingot during the loading process, a pair of mutually symmetrical clamping mechanisms 400 are provided on both sides of the inverted U-shaped seat 330, thereby realizing the functions of automatic material taking and unloading.

[0052] exist Figure 6 and Figure 7 In the figure, the clamping mechanism 400 includes an adjusting column 410 which is slidably connected to the side wall of the U-shaped seat 330, and the end of the adjusting column 410 away from the side wall of the U-shaped seat 330 is fixedly connected to a clamping plate 420, and a first spring 430 is sleeved between the clamping plate 420 and the side wall of the U-shaped seat 330 on the periphery of the adjusting column 410, and the end of the adjusting column 410 away from the first spring 430 is fixedly connected to an arc-shaped push plate 440, and the shape of the arc-shaped push plate 440 is concave (the concave surface faces upward), and a positioning cap 450 is provided at the end of the adjusting column 410 away from the adjusting column 410.

[0053] The improvement lies in that when the hydraulic rod 320 drives the U-shaped seat 330 to move downward, the positioning cap 450 will first be sleeved on the top of the positioning mechanism 500, and then the top of the positioning mechanism 500 will gradually begin to contact with the bottom convex surface of the arc-shaped push plate 440 (the initial contact position is a non-end position, such as the midpoint). As the arc-shaped push plate 440 continues to move downward, the two positioning mechanisms 500 begin to gradually move away from each other under the driving action of the arc-shaped push plate 440, and the adjusting column 410 is sleeved on the positioning mechanism 500 together with the positioning cap 450, so that the two splints 420 follow the adjusting column 410 connected to themselves to expand synchronously, thereby increasing the distance between the two splints 420 until all the zinc ingots are located between the two splints 420. At this time, the hydraulic rod 320 is started again to perform the opposite operation to the above. The hydraulic rod 320 drives the U-shaped seat 330 to move upward, and the downward pressure of the arc-shaped push plate 440 on the positioning mechanism 500 gradually decreases, so that the distance between the two clamping plates 420 gradually recovers and becomes smaller, thereby gradually clamping the zinc ingot. When the zinc ingot follows the driving mechanism 200 to move above the die-casting tank 140, the hydraulic rod 320 drives the U-shaped seat 330 downward again, thereby gradually lowering the zinc ingot into the die-casting tank 140.

[0054] In order to prevent the zinc ingot from being worn by the sliding feeding method, the existing zinc ingot feeding device adopts a scheme of first clamping the zinc ingot, then moving it away from the work surface, and finally placing it in the die-casting position. However, this brings new problems: the zinc ingot needs to be placed in the clamping mechanism 400 first, then the zinc ingot is fixed, and then the clamping mechanism 400 is driven to move to the die-casting position, and finally the zinc ingot is put down. At the same time, when the zinc ingot is put down, it is also necessary to align it with the die-casting position to prevent the zinc ingot from colliding with the processing table 120 when it falls and not falling accurately on the die-casting position. These problems make the working process more cumbersome and affect the processing efficiency of automobile chassis parts.

[0055] Figure 7 and Figure 8 The figure shows the working state of the positioning mechanism 500 and the clamping mechanism 400 cooperating with each other. The specific structure of the positioning mechanism 500 is disclosed below. The positioning mechanism 500 includes a limiting groove 510 fixedly connected to the top of the processing table 120, and a positioning rod 520 is slidably connected in the limiting groove 510. The positioning rod 520 and the positioning cap 450 are located on the same horizontal line. A sliding rod 530 is fixedly connected to the bottom of the positioning rod 520, and one end of the sliding rod 530 away from the positioning rod 520 is slidably connected to the side wall of the limiting groove 510. The outer periphery of the sliding rod 530 is provided with a second spring 540 between the positioning rod 520 and the inner wall of the limiting groove 510.

[0056] That is, when the hydraulic rod 320 drives the U-shaped seat 330 to drive the two clamping plates 420 to move downward, the positioning cap 450 is first sleeved on the positioning rod 520. Since the force applied by the arc-shaped push plate 440 to the positioning rod 520 can cause the positioning rod 520 to expand outward, and the positioning cap 450 is sleeved on the positioning rod 520, when the positioning rod 520 drives the sliding rod 530 to slide outward, the two positioning rods 520 pull the two clamping plates 420 to slide away from each other through the adjustment column 410, and the second spring 540 is compressed by the bottom of the positioning rod 520. The two clamping plates 420 continue to move downward with the U-shaped seat 330 until the zinc ingot is completely located between the two clamping plates 420. At this time, the hydraulic rod 320 gradually retracts the U-shaped seat 330 through the movable end, and gradually clamps the zinc ingot through the two clamping plates 420 that are close to each other, and the positioning rod 520 is also gradually reset under the action of the restoring force of the second spring 540. The two clamping plates 420 holding the zinc ingot are moved to the top of the die-casting tank 140 by the drive mechanism 200, and then the U-shaped seat 330 is driven downward by the hydraulic rod 320, and the positioning cap 450 is sleeved on the positioning rods 520 on both sides of the die-casting tank 140 to ensure that the zinc ingot can then accurately slide into the die-casting tank 140.

[0057] In order to quickly transfer the zinc ingot to the die-casting position after clamping it, a driving mechanism 200 is provided to drive the lifting mechanism 300, the clamping mechanism 400 and the entire zinc ingot to move.

[0058] like Figure 5 As shown, the driving mechanism 200 includes a slide rail 210 fixedly connected to the top of the processing table 120, the top of the slide rail 210 is slidably connected to a slide seat 220, and the slide seat 220 is rotatably connected to a plurality of pulleys 230 on one side close to the slide rail 210, one of the pulleys 230 is driven by a motor 240.

[0059] The improvement lies in that after the two clamps 420 clamp the zinc ingot, the power of the motor 240 is turned on, and the motor 240 drives the pulley 230 coaxially connected to its own output shaft to rotate. Driven by the friction between the pulley 230 and the slide rail 210, the slide 220 slides along the slide rail 210, and the clamped zinc ingot is transported by the two slides 220 along the path of the slide rail 210.

[0060] Embodiment 2: This embodiment is based on the content provided in Embodiment 1, and the second purpose is to provide a feeding method for a zinc ingot precise feeding and clamping device, and the specific steps are as follows:

[0061] S1. Place multiple zinc ingot raw materials in the feeding trough 150, push the zinc ingot at the bottom to slide on the top of the roller group 130, until the zinc ingot at the bottom moves between the two positioning mechanisms 500. At this time, the remaining zinc ingot raw materials in the feeding trough 150 slide down to the top of the roller group 130 under the action of their own gravity;

[0062] S2. Start the hydraulic rod 320. When the hydraulic rod 320 drives the U-shaped seat 330 to move downward, the positioning cap 450 will first be sleeved on the top of the positioning mechanism 500. Then, the top of the positioning mechanism 500 begins to gradually contact with the bottom convex surface of the arc-shaped push plate 440 (the initial contact position is a non-end position, such as the midpoint). As the arc-shaped push plate 440 continues to move downward, the two positioning mechanisms 500 begin to gradually move away from each other under the driving action of the arc-shaped push plate 440, and the adjustment column 410 is sleeved on the positioning mechanism 500 together with the positioning cap 450, so that the two clamps 420 follow the adjustment column 410 connected to themselves and expand synchronously, so that the distance between the two clamps 420 increases until all the zinc ingots are located between the two clamps 420. At this time, the hydraulic rod 320 is started again to perform the opposite operation to the above operation. The hydraulic rod 320 drives the U-shaped seat 330 to move upward, and the downward pressure of the arc-shaped push plate 440 on the positioning mechanism 500 gradually decreases, so that the distance between the two clamping plates 420 gradually recovers and becomes smaller, thereby gradually clamping the zinc ingot. When the zinc ingot follows the driving mechanism 200 to move above the die-casting tank 140, the hydraulic rod 320 drives the U-shaped seat 330 to move downward again, thereby gradually lowering the zinc ingot into the die-casting tank 140;

[0063] S3, start the motor 240, the two slides 220 drive the two clamping plates 420 holding the zinc ingot to move toward the die-casting tank 140, after the U-shaped seat 330 is located directly above the die-casting tank 140, start the hydraulic rod 320 to drive the two clamping plates 420 holding the zinc ingot to move toward the die-casting tank 140 below, when the two positioning caps 450 are respectively in contact with the positioning rods 520 on both sides of the die-casting tank 140 (to ensure that the zinc ingot can accurately slide into the die-casting tank 140), under the drive of the hydraulic rod 320, the two clamping plates 420 and the two positioning rods 520 move away from each other, so that the zinc ingot gradually slides into the die-casting tank 140, and then the zinc ingot falling into the die-casting tank 140 is die-casted by the die-casting machine 160;

[0064] S4, start the two slides 220 to drive the U-shaped seat 330 back to the zinc ingot raw material on the roller group 130, and repeat the above steps.

[0065] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
