Description

Technical Field

[0001] The invention belongs to the technical field of pad processing, and in particular relates to a pad grinding loading and unloading device and method. Background Art

[0002] The pad is one of the important parts of the fastener system of high-speed rail, freight heavy load, and urban rail transit. It can maintain the stability of the rail line fastener system and meet the requirements of line safety. Pad products must be cleaned and polished to remove the seams and burrs on the surface so that the surface quality and external dimensions can meet the requirements. The cleaning and polishing method is to use electric or pneumatic grinding tools (such as angle grinders, straight grinders, grinding wheels, etc.) to grind the pad surface.

[0003] For example, the Chinese patent publication number is: CN110722355A, which discloses an integrated processing equipment for high-speed rail shock-absorbing pads of different styles. The technical solution reported in the patent is as follows:

[0004] The integrated processing equipment includes a base and a collecting box, the front and rear sides of the base are slidably connected with a slide, the slide is provided with a groove, the moving block is arranged on the upper side of the compression spring, the top of the slide is threadedly connected with a pressure rod, the collecting box is arranged on the lower side of the through hole, a first bracket and a second bracket are fixed on the base, the first bracket and the second bracket are slidably connected with a slide block, and a hydraulic cylinder is arranged in the slide block, the lower side of the hydraulic cylinder on the first bracket is connected to the first clamping block through a hydraulic rod, and the lower side of the hydraulic cylinder on the second bracket is connected to the third motor through a hydraulic rod.

[0005] The above technical solution realizes integrated processing equipment for high-speed rail shock-absorbing pads of different styles. After the drilling is completed, the drilling position of the material is moved to the lower side of the grinding block. The grinding block can move downward and rotate during the downward movement to polish the drilling position.

[0006] However, the pads used for rails are mostly pads of specified structural dimensions. In the actual processing, the pads are polished by automated polishing equipment.

[0007] Therefore, the technical problem is how to load the bulky pad onto the workbench of the grinding equipment. Specifically, the current loading method in the workshop is manual loading, and the efficiency and stability of manual loading and unloading are greatly affected by human factors. For example, during the loading process, once the handheld pad is loose, it is easy to be hit by the falling pad. At the same time, since the pad is an iron casting, the pad itself has a certain weight, which makes it easier for the pad to fall during the loading process. In addition, since the production of the pad is batch production and processing, the manual handling method of loading is obviously not only inefficient, but also has a very large labor workload.

[0008] At the same time, during the manual loading process, it is necessary to stand and bend for a long time, which is very labor-intensive. Therefore, it is obvious that the traditional method of manual loading cannot meet the needs of production and processing. Summary of the invention

[0032] The length of the first upper slope portion is smaller than the length of the second upper slope portion, and the slope of the first upper slope portion is greater than the slope of the second upper slope portion.

[0033] The present invention also discloses a method for loading and unloading a pad based on the grinding device, which specifically includes the following steps:

[0034] (1) The pad is loaded from one end of the slide rail rod and transferred to the other end of the slide rail rod, which is the first stroke. The specific method of the first stroke includes the following steps:

[0035] The pad is fed to one end of the slide rail, and then the grabbing cylinder drives the grabbing seat down until the claw rod enters the mechanical hole on the pad and grabs the pad;

[0036] The first stroke cylinder pushes the grabbing cylinder and the pad forward to the other end of the slide rail rod, reaching the end point of the first stroke;

[0037] The material grabbing cylinder carries the material grabbing seat and the claw rod and lifts it until the claw rod is separated from the pad to complete the first stroke. After the first stroke is completed, the first stroke cylinder is reset;

During the sliding process of the slide rail rod, the pads between the slide rail rods continue to slide forward synchronously, and then the pads are unloaded onto the grinding jig table, and the grinding equipment performs the grinding operation. At this time, the pad A completes the second stroke; the second stroke cylinder is reset;

[0041] The present invention has the following beneficial effects:

[0042] 1. The automatic loading and unloading device adopts a layered combination structure. Specifically, it integrates the grabbing and loading mechanism, the first stroke mechanism, the second stroke mechanism and the unloading mechanism through the side installation to realize the working process. In the limited space occupied by the mechanical equipment, it completes the complex loading, movement and unloading movements.

[0043] 2. Through the mechanical structure coordinated in the first stroke, the claw rod structure is used to realize the grabbing process, and the claw rod is inserted into the mechanical hole on the pad, so that the pad can move horizontally during the first stroke movement. At the same time, because the pad is in the grabbing state, the pad is not easy to shake on the slide rod during the movement, ensuring that the pad reaches the terminal position from the feeding end of the slide rod, and the pad always maintains the correct posture, so that the pad can accurately unload on the jig table of the grinding equipment during the subsequent unloading process without deviation.

[0044] 3. During the second stroke, the piston rod of the second stroke cylinder is fixedly connected to a slide rail frame, and the inner end of the slide rail frame is fixedly connected to a slide seat spaced apart from the upper and lower sides, so that the slide rail frame-slide rail rod structure continues to slide forward under the drive of the second stroke cylinder, and the pad and the slide rail frame move synchronously by means of limited sliding. The advantage of this method is that the pad is kept fixed on the slide rail in an unchanged position, and when it reaches the jig table of the grinding equipment, the pad can be accurately loaded onto the jig table of the grinding equipment due to its precise position.

[0045] 4. The material unloading claw structure includes a long claw column fixedly installed on the material unloading claw seat, and a material unloading hook claw is fixedly connected to the long claw column. The lower end of the material unloading hook claw is a hook part bent inward. During the material unloading process, the hook part is hooked on the mechanical hole on the pad. In this way, the pad is pulled in a hooking and pulling manner. This method can also ensure that the posture remains accurate during the material unloading process when the pad slides down.

[0046] 5. The device disclosed in the present invention realizes automatic loading, pushing and unloading. This method is not only highly efficient, but also does not require manual loading and unloading. It solves the technical defects of traditional manual loading, which has high operation intensity and high operation risks. At the same time, it greatly increases the grinding production efficiency of the pad. At the same time, it has a high degree of automation and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] Example 1

[0062] like Figure 1-8As shown, a pad grinding loading and unloading device includes a side frame 1, on which a first stroke mechanism 2 is assembled and connected, and the first stroke mechanism 2 is assembled and connected with 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 to move horizontally to the end position of the first stroke; the pad A grinding loading and unloading device also includes a second stroke mechanism 4, and the second stroke mechanism 4 includes a slide rail 43, on which the pad slides (during the first stroke, the pad slides on the slide rail 43), and the second stroke mechanism 4 is used to continue to push the pad A to the grinding jig table; the pad A grinding loading and unloading device also includes a unloading mechanism 5, which is used to unload the polished pad A. In this way, automatic loading and unloading can be achieved, and the technical defects of high labor intensity and certain risks in manual loading and unloading can be solved.

[0063] Specifically, the first stroke mechanism 2 includes a first stroke cylinder 21 fixedly mounted on the side frame 1 (the cylinder barrel of the first stroke cylinder 21 is mounted on the upper end position of the side wall of the side frame 1 through a fixed frame), the piston rod of the first stroke cylinder 21 is fixedly connected to the side wall with a horizontal slide 23 (the horizontal slide 23 includes an inner end frame portion 231 and a horizontal frame portion 232 fixed to the inner end frame portion 231), and the material grabbing and feeding mechanism 3 is fixedly mounted on the horizontal slide 23 (specifically, on the horizontal frame portion 232).

[0064] Specifically, the inner end (inner end frame portion 231) of the horizontal slide 23 is fixedly connected with a plurality of fixed guide seats (specifically, two fixed guide seats 2311 arranged at intervals in the upper and lower directions), and the side frame 1 is fixedly assembled with two slide bars 22 slidably connected with the fixed guide seats. The piston rod of the first stroke cylinder 21 is fixedly connected to the piston rod seat on the inner end of the horizontal slide 23. At the same time, the top of the inner end frame portion 231 is fixedly connected with a Z-shaped slide plate 2321, which slides at the top position of the side frame 1, thereby increasing the stability of the sliding.

[0065] Meanwhile, the material grabbing and feeding mechanism 3 comprises a material grabbing cylinder 31 , and the cylinder barrel of the material grabbing cylinder 31 is fixedly mounted on the rear side wall of the horizontal slide 23 .

[0066] Specifically, the piston rod of the grabbing cylinder 31 is fixedly installed with a grabbing structure; the grabbing structure includes a grabbing seat 32 (shaped like a V-shaped structure). Specifically, the piston rod of the grabbing cylinder 31 is fixedly connected with a mounting seat, and the mounting seat is fixedly installed on the top of the grabbing seat 32.

[0067] At the same time, guide rods are fixedly connected to both sides of the top of the mounting seat, and the guide rods are slidably connected to the guide seats fixedly connected to the rear side wall of the horizontal slide 23, so as to increase the stability of the grabbing cylinder 31 during the lifting and lowering driving process.

[0068] The material grabbing seat 32 is fixedly connected to two claw rods 33 arranged at intervals. During the material grabbing process, the claw rods 33 are inserted into the mechanical holes a on the pad A (the mechanical holes a are the hole structures provided on the pad A blank, and the pad itself has the mechanical holes a in its structure).

[0069] During the working process, the material grabbing cylinder 31 drives the material grabbing seat 32 to descend until the claw rod 33 enters the mechanical hole a on the pad A and grabs the pad A (stuck). After grabbing the material, at this time, the first stroke cylinder 21 pushes the material grabbing cylinder 31 and the pad A (because the claw rod 33 is stuck in the mechanical hole a, under the push of the claw rod 33, the pad is pushed on the slide rail frame 42 described below) to move forward 500mm to reach the end of the first stroke. Subsequently, the material grabbing cylinder 31 carries the material grabbing seat 32-claw rod 33 to be raised (25mm) until the claw rod 33 is separated from the pad A (mechanical hole a on the pad), completing the first stroke. After the first stroke is completed, the first stroke cylinder 21 is reset.

[0070] Example 2

[0071] like Figure 1-8 As shown, based on the structure of Example 1, after the pad A completes the first stroke, in order to push the pad A forward to enter the second stroke, the second stroke mechanism 4 further includes a second stroke cylinder 41.

[0072] 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), and the top of the slide rail frame 42 is fixedly connected to two slide rails 43 spaced apart on both sides, and the pad A slides between the slide rails 43 (during the first stroke, the pad A is also pushed by the first stroke cylinder 21 to slide between the slide rails 43 to the middle end position of the first stroke).

[0073] Specifically, the inner end of the slide rail frame 42 is fixedly connected with a slide seat 422 which is spaced apart up and down (the top of the outer end of the slide rail frame 42 is fixedly connected with a boss 421, and the boss 421 is located between the slide rail rods 43). Correspondingly, the side frame 1 is fixedly connected with a slide rod 4221 which is spaced apart up and down, and the slide seat 422 is slidably connected to the slide rod 4221.

[0074] During the working process, when the second stroke cylinder 41 is driven, the slide rail frame 42 continues to slide forward. During the sliding process of the slide rail frame 42, the pad A between the slide rail rods 43 continues to slide forward for 200 mm, and is then sent to the grinding jig 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.

[0075] Example 3

[0076] like Figure 1-8 As shown, based on the structure of Example 2, this embodiment fixes an upper rail end frame 431 between the end positions of the terminal ends of the slide rail rod 43. The rail end frame 431 increases the stability of the slide rail rods 43 on both sides and achieves the resistance of the pad A.

[0077] Specifically, the rail end frame 431 includes a horizontal portion, and the two ends of the horizontal portion are integrally formed with an upwardly inclined oblique body portion, the slide rail rod 43 is fixed on the oblique body portion, and the oblique body portion is integrally formed with a convex portion 4311. After the pad A moves to the terminal position of the slide rail rod 43, it is resisted by the convex portion 4311.

[0078] The purpose of this method is that when the slide rail frame moves to the jig table attachment of the grinding equipment and the cylinder is stationary, the convex portion 4311 can be used to prevent the pad A from rushing out of the slide rail rod 43, thereby keeping the pad A in position.

[0079] Example 4

[0080] like Figure 1-8 As shown, based on the structure of Example 3, after the pad A is polished, in order to facilitate the unloading of the pad A, the unloading mechanism 5 includes a unloading cylinder 51, and the cylinder barrel of the unloading cylinder 51 is fixedly connected to a cylinder mounting frame 53, and the inner end of the cylinder mounting frame 53 is fixedly mounted on the side frame 1.

[0081] At the same time, the piston rod of the feeding cylinder 51 is fixedly connected to a feeding claw seat 52, and two feeding claw structures arranged at intervals are fixedly connected to the feeding claw seat 52. At the same time, both ends of the feeding claw seat 52 are fixedly connected to guide rails 522, and the cylinder mounting frame 53 is fixedly connected to a guide rail seat 521 that is slidably connected to the guide rails 522.

[0082] The material unloading claw structure includes a long claw column 54 fixedly mounted on a material unloading claw seat 52, to which a material unloading hook 541 is fixedly connected. The lower end of the material unloading hook 541 is a hook portion bent inwardly. During the unloading process, the hook portion is hooked on the mechanical hole a on the pad A.

[0083] During the material unloading process, the unloading claw seat 52-claw rod 33-unloading hook claw 541 is driven by the unloading cylinder 51 to hook the material unloading claw seat 52-claw rod 33-unloading hook claw 541 on the mechanical hole a on the pad A, and the pad A is hooked before unloading.

[0084] Specifically, a pair of spaced-apart material unloading ramps 6 are fixedly connected to the lower end of the side frame. During the unloading process, the pad A slides on the top of the material unloading ramp 6 (a slide groove 61 is provided on the top of the material unloading ramp 6 to adapt to the bottom boss of the pad A to increase the accuracy of the sliding down); during the unloading process, the downward slope of the material unloading ramp 6 is used to facilitate material unloading (that is, during the unloading process, the pad A is placed from the jig table to the high position of the material unloading ramp 6, and then slides from the high position to the low position).

[0085] The bottom of the side frame 1 is fixedly connected with a bracket, and the unloading ramp 6 is fixedly mounted on the bracket.

[0086] Example 5

[0087] like Figure 1-9 As shown, based on the structure of Example 4, in the process of blanking the pad, in order to ensure that the hook part on the blanking hook claw 541 can be accurately hooked on the mechanical hole a on the pad A, the pad A is hooked before blanking, and the shape of the blanking ramp 6 is designed into three sections, as follows:

[0088] The unloading ramp 6 includes a first upper slope portion 6a, a second upper slope portion 6b integrally formed with the first upper slope portion 6a, and a horizontal sliding portion 6c that slides horizontally.

[0089] The length of the first upper slope 6a is less than the length of the second upper slope 62, and the slope is greater than the slope of the second upper slope 6b. The purpose is that during the working process, when the pad A is unloaded from the jig table of the grinding equipment, the pad A can easily fall onto the first upper slope 6a, and under the guidance of the first upper slope 6a, the pad A slides and falls between the first upper slope 6a and the second upper slope 6b. At this time, the pad A is partially supported on the unloading ramp 6 and has a certain support stability. Subsequently, the unloading hook 541 can move forward and accurately hook on the mechanical hole a on the pad, and then pull backward. During the backward pulling process, as the pad A goes uphill, the depth of the unloading hook 541 hooking into the mechanical hole a becomes deeper and deeper, thereby achieving higher and higher stability of hooking and pulling. Therefore, the three-stage slope method greatly improves the stability of the pad A during the unloading process from the jig table of the grinding equipment to the unloading slope plate 6 and the movement being hooked and dragged. In this method, the pad A also maintains an unchanged posture during the movement, which is convenient for subsequent stacking of materials.

[0090] Example 5

[0091] like Figure 1-8As shown, based on the structure of Example 4, in accordance with the existing method, when the pad A is traveling in the first stroke and the second stroke, in order to monitor the traveling distance of the pad A, a distance measuring sensor mechanism 7 is installed at the front end of the side frame 1 in accordance with the existing method. The distance measuring sensor mechanism 7 includes a distance measuring sensor 72, and the distance measuring sensor 72 is fixed to the side frame 1 through a sensor bracket 71. Under normal circumstances, 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 moving distance of the horizontal slide 23.

[0092] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.

10. A method for loading and unloading a pad using the pad grinding loading and unloading device according to any one of claims 1 to 9, characterized in that: The steps include: (1) The pad is loaded from one end of the slide rail frame and transferred to the other end of the slide rail frame, which is the first stroke. The specific method of the first stroke includes the following steps: The pad is fed to one end of the slide rail, and then the grabbing cylinder drives the grabbing seat down until the claw rod enters the mechanical hole on the pad and grabs the pad; The first stroke cylinder pushes the grabbing cylinder and the pad forward to the other end of the slide rail rod, reaching the end point of the first stroke; The material grabbing cylinder carries the material grabbing seat and the claw rod and lifts it until the claw rod is separated from the pad to complete the first stroke. After the first stroke is completed, the first stroke cylinder is reset; (2) The sliding rail rod and the pad move synchronously to the jig table of the grinding equipment, which is the second process. The specific method of the second process is as follows: Driven by the second stroke cylinder, the slide rail rod continues to slide forward. During the sliding process of the slide rail rod, the pads between the slide rail rods continue to slide forward synchronously, and then the pads are unloaded onto the grinding jig table, and the grinding equipment performs the grinding operation. At this time, the pad A completes the second stroke; the second stroke cylinder is reset; (3) After the grinding is completed in the manner of step (2), the grinding equipment unloads the ground pad onto the unloading mechanism, and the unloading mechanism hooks the pad and unloads the pad by pulling it.
