Description

Technical Field

[0001] This utility model belongs to the field of pad processing technology, and in particular relates to a pad grinding and loading / unloading device. Background Technology

[0002] Track pads are crucial components of fastening systems for high-speed rail, heavy-haul freight, and urban rail transit lines. They maintain the stability of the track fastening system and meet the requirements for track safety. Track pad products must undergo cleaning and grinding to remove surface burrs and imperfections to ensure surface quality and dimensional accuracy. Cleaning and grinding are performed using electric or pneumatic grinding tools (such as angle grinders, straight grinders, and grinding wheels) to polish the track pad surface.

[0003] Before grinding, the backing plate needs to be loaded onto the grinding equipment. Currently, loading is mostly done manually, and the efficiency and stability of manual loading and unloading are greatly affected by human factors. For example, during the loading process, if the hand holding the backing plate loosens, it is easy to be injured by a falling backing plate. At the same time, since the backing plate is made of cast iron, it has a certain weight, which further increases the risk of the backing plate falling during loading.

[0004] Furthermore, since the production of the pads is a mass production process, manual handling for loading is obviously not only inefficient, but also involves a very heavy workload.

[0005] Meanwhile, manual material loading requires prolonged standing and bending, resulting in high work intensity. Therefore, it is clear that traditional methods relying entirely on manual material loading cannot meet production and processing needs. Utility Model Content

[0042] Example 1

[0043] like Figure 1-7As shown, a pad grinding and unloading device includes a side frame 1, on which a first stroke mechanism 2 is mounted and connected. The first stroke mechanism 2 is connected to a material-grabbing and loading mechanism 3. After the material-grabbing and loading mechanism 3 grabs the pad A, the first stroke mechanism 2 pushes the material-grabbing and loading mechanism 3 and the pad A horizontally to the end position of the first stroke. The pad A grinding and unloading device also includes a second stroke mechanism 4, which includes a slide rail 43 on which the pad slides (during the first stroke, the pad slides on the slide rail 43). The second stroke mechanism 4 is used to further push the pad A to the grinding fixture table. The pad A grinding and unloading device also includes a unloading mechanism 5, which is used to unload the ground pad A. This method achieves automated loading and unloading, solving the technical defects of manual loading and unloading, which involves high labor intensity and certain risks.

[0044] Specifically, the first stroke mechanism 2 includes a first stroke cylinder 21 fixedly installed on the side frame 1 (the cylinder barrel of the first stroke cylinder 21 is installed on the upper end of the side wall of the side frame 1 through a fixed frame), and the piston rod of the first stroke cylinder 21 is fixedly connected to a horizontal slide 23 (the horizontal slide 23 includes an inner end frame 231 and a horizontal frame 232 fixed to the inner end frame 231). The material gripping and feeding mechanism 3 is fixedly installed on the horizontal slide 23 (specifically on the horizontal frame 232).

[0045] Specifically, the inner end (inner end frame 231) of the horizontal slide 23 is fixedly connected to several fixed guide seats (specifically, two fixed guide seats 2311 spaced vertically apart). Two sliding rods 22, slidably connected to the fixed guide seats, are fixedly mounted on the side frame 1. The piston rod of the first-stroke cylinder 21 is fixedly connected to a piston rod seat on the inner end of the horizontal slide 23. Simultaneously, a Z-shaped sliding plate 2321 is fixedly connected to the top of the inner end frame 231, and the Z-shaped sliding plate 2321 slides at the top position of the side frame 1, thereby increasing the stability of the sliding motion.

[0046] Meanwhile, the material feeding mechanism 3 includes a material feeding cylinder 31, the cylinder of which is fixedly installed on the rear side wall of the horizontal slide 23.

[0047] Specifically, the piston rod of the gripping cylinder 31 is fixedly mounted with a gripping structure; the gripping structure includes a gripping seat 32 (shaped like a V-shape), specifically, the piston rod of the gripping cylinder 31 is fixedly connected to a mounting seat, and the mounting seat is fixedly mounted on the top of the gripping seat 32.

[0048] Meanwhile, guide rods are fixedly connected to the top two sides of the mounting base, and the guide rods are slidably connected to the guide seat fixedly connected to the rear side wall of the horizontal slide 23, which is used to increase the stability of the lifting drive process of the material gripping cylinder 31.

[0049] Two spaced claw bars 33 are fixedly connected to the material gripping seat 32. During the material gripping process, the claw bars 33 are engaged in the mechanical hole a on the pad A (the mechanical hole a is a hole structure that is inherent on the blank of the pad A, and the pad itself has a mechanical hole a).

[0050] During operation, the gripping cylinder 31 drives the gripping seat 32 to descend until the claw rod 33 enters the mechanical hole a on the pad A, gripping (locking) the pad A. After gripping, the first-stroke cylinder 21 pushes the gripping cylinder 31 and the pad A (because the claw rod 33 is locked in the mechanical hole a, the pad is pushed on the slide rail 42 below) forward 500mm, reaching the end of the first stroke. Subsequently, the gripping cylinder 31 lifts the gripping seat 32 and the claw rod 33 by 25mm until the claw rod 33 disengages from the pad A (mechanical hole a), completing the first stroke. After the first stroke is completed, the first-stroke cylinder 21 resets.

[0051] Example 2

[0052] like Figure 1-7 As shown, based on the structure of Embodiment 1, in order to push the pad A forward into the second stroke after the pad A completes the first stroke, the second stroke mechanism 4 also includes a second stroke cylinder 41.

[0053] Specifically, a slide rail frame 42 is fixedly connected to the piston rod of the second stroke cylinder 41 (the cylinder barrel of the second stroke cylinder 41 is fixedly installed on the side wall of the side wall, located below the first stroke cylinder 21). Two slide rail rods 43 are fixedly connected to the top of the slide rail frame 42 at intervals on both sides. The pad A slides between the slide rail rods 43 (during the first stroke, the pad A also slides between the slide rail rods 43 to the end position of the first stroke under the push of the first stroke cylinder 21).

[0054] Specifically, the inner end of the slide rail frame 42 is fixedly connected to a slide seat 422 that is spaced vertically (the top of the outer end of the slide rail frame 42 is fixedly connected to a boss 421, which is located between the slide rail rods 43). Correspondingly, the side frame 1 is fixedly connected to a slide rod 4221 that is spaced vertically, and the slide seat 422 is slidably connected to the slide rod 4221.

[0055] During operation, when the second-stroke cylinder 41 drives the slide rail 42, the slide rail frame 42 continues to slide forward. During the sliding of the slide rail frame 42, the pad A between the slide rail rods 43 continues to slide forward 200mm and is then fed onto the grinding tool table (not shown in the figure) in the existing manner, and the grinding equipment performs the grinding operation. At this time, the pad A completes the second stroke.

[0056] Example 3

[0057] like Figure 1-7As shown, in this embodiment, based on the structure of embodiment 2, after the pad A is polished, in order to facilitate the unloading of the pad A, the unloading mechanism 5 includes an unloading cylinder 51. The cylinder barrel of the unloading cylinder 51 is fixedly connected to a cylinder barrel mounting bracket 53, and the inner end of the cylinder barrel mounting bracket 53 is fixedly mounted on the side frame 1.

[0058] Meanwhile, the piston rod of the feeding cylinder 51 is fixedly connected to a feeding claw seat 52, and two spaced-apart feeding claw structures are fixedly connected to the feeding claw seat 52. At the same time, guide rail rods 522 are fixedly connected to both ends of the feeding claw seat 52, and a guide rail seat 521 that slides and connects to the guide rail rods 522 is fixedly connected to the cylinder mounting bracket 53.

[0059] The feeding claw structure includes a long claw column 54 fixedly installed on the feeding claw seat 52. A feeding hook claw 541 is fixedly connected to the long claw column 54. The lower end of the feeding hook claw 541 is a hook part that is bent inward. During the feeding process, the hook part hooks onto the mechanical hole a on the pad A.

[0060] During the unloading process, driven by the unloading cylinder 51, the hook part on the unloading claw seat 52-claw bar 33-unloading hook claw 541 hooks onto the mechanical hole a on the pad A, and the pad A is hooked before unloading.

[0061] Specifically, a pair of spaced-apart feeding ramps 6 are fixedly connected to the lower end of the side frame. During the feeding process, the pad A slides on the top of the feeding ramp 6 (the top of the feeding ramp 6 has a groove 61 that matches the bottom boss of the pad A to increase the accuracy of the sliding). During the feeding process, the downward slope of the feeding ramp 6 is used to facilitate feeding (that is, during the feeding process, the pad A is placed from the jig table to the high position of the feeding ramp 6 and then slides down from the high position to the low position).

[0062] The bottom of the aforementioned side frame 1 is fixedly connected to a bracket, and the material discharge ramp 6 is fixedly installed on the bracket.

[0063] Example 4

[0064] like Figure 1-7 As shown, this embodiment, based on the structure of embodiment 3, follows the existing method. During the first and second strokes of the pad A's movement, to monitor the distance traveled by the pad A, a distance measuring sensor 7 is installed at the front end of the side frame 1. The distance measuring sensor 7 includes a distance measuring sensor 72, which is fixed to the side frame 1 by a sensor bracket 71. Normally, the distance measuring sensor 72 is supported on the top of the horizontal frame portion of the horizontal slide 23. When the horizontal slide 23 moves, the distance measuring sensor 72 is suspended in the air and measures the distance traveled by the horizontal slide 23.

[0065] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
