Description

Technical Field

[0001] This utility model relates to the field of pin sleeve cutting machine technology, and in particular to an anti-breakage tool for pin sleeve cutting machine. Background Art

[0002] Pin sleeves are components that work in conjunction with pins. They are widely used in engineering machinery, automobiles, trains, ships and other applications with movable arms.

[0003] However, in the existing technology, the cutting tool of the pin sleeve cutting machine may break during the cutting operation. Common pin sleeve cutting machines are not equipped with corresponding protective mechanisms. The broken tool fragments fly out directly and may injure the surrounding operators, which is a significant safety risk. Therefore, we propose an anti-breakage tool for pin sleeve cutting machines. Utility Model Content

[0004] This utility model provides an anti-splitting tool for a pin sleeve cutting machine, which solves the above-mentioned technical problems.

[0005] The present invention provides the following solution to the above-mentioned technical problems: A chip-resistant cutting tool for a pin-cutting machine includes a fixed plate. A mounting groove is vertically formed on the lower end face of the fixed plate. A cutting tool is vertically slidably fitted onto the inner wall of the mounting groove. The cutting tool is connected to the mounting groove via a plug-in mechanism. A fixed frame is fixedly installed on the upper end face of the fixed plate. Support members that slide through the fixed plate are vertically arranged on both side walls of the cutting tool. The support members movably pass through the fixed frame. A connecting plate is slidably fitted onto the upper end face of the fixed plate. Multiple support members are fixedly connected to the connecting plate. The connecting plate is fixedly connected to the fixed frame via a first spring that is movably sleeved on the outer wall of the support member. A blocking frame is sleeved around the outer ring of the fixed plate. The blocking frame is connected to the fixed plate via a sliding mechanism.

[0006] Preferably, the insertion mechanism includes two transversely formed grooves on the outer wall of the fixed plate, the grooves passing through the mounting slot, the inner wall of the grooves being laterally slidably fitted with insertion rods, the insertion rods movably passing through the cutter, the ends of the two insertion rods being fixedly connected by a pulling member, the grooves having an internal groove in the middle, the outer wall of the insertion rods being fixedly fitted with a fixing plate, the fixing plate being fixedly connected to the inner wall of the internal groove by a second spring movably fitted on the outer wall of the insertion rods.

[0007] Preferably, the sliding mechanism includes a connecting rod that is horizontally fixedly installed on the inner side wall of the barrier frame, and a sliding groove is vertically opened on the outer side wall of the fixed plate, and the connecting rod is slidably connected to the inner side wall of the sliding groove.

[0009] Preferably, the blocking frame surrounds the cutting tool, and an electromagnetic block is provided on the inner wall of the blocking frame.

[0010] The beneficial effects of this utility model are:

[0011] 1. By setting up a barrier frame, the barrier frame is connected to the sliding groove on the outer surface of the fixed plate through a connecting rod. The barrier frame can move up and down to ensure that it does not hinder the cutting work of the tool and surrounds the tool. When the tool breaks, it can prevent the tool fragments from flying outward. At the same time, an electromagnetic block is set on the inner wall of the barrier frame to attract the tool fragments and prevent the tool fragments from scattering.

[0012] 2. By using a support component set on the outer wall of the tool, the tool is supported and protected, reducing the chance of tool breakage. The support component can move upward when squeezed, ensuring the normal operation of the tool. At the same time, the tool is fixed by plugging in the connecting rod, making tool disassembly and replacement quicker and easier.

[0021] The following is in conjunction with the appendix Figure 1-4 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0022] like Figure 1-4 As shown, this utility model discloses an anti-breakage cutter for a pin-cutting machine, comprising a fixed plate 1, a vertically formed mounting groove 2 on the lower end face of the fixed plate 1, a cutter 3 vertically slidingly fitted into the inner wall of the mounting groove 2, the cutter 3 being connected to the mounting groove 2 via a plug-in mechanism, a fixed bracket 4 fixedly mounted on the upper end face of the fixed plate 1, and vertically formed sliding support members 5 penetrating the fixed plate 1 on both sides of the cutter 3. The support members 5 provide support, distribute the force, improve the strength of the cutter 3, and reduce the possibility of the cutter 3 breaking. The support members 5 movably penetrate the fixed bracket 4 for fixation. A connecting plate 6 is slidably fitted on the upper end face of plate 1. Multiple support members 5 are fixedly connected to the connecting plate 6. The connecting plate 6 is fixedly connected to the fixing frame 4 through a first spring 7 that is movably sleeved on the outer wall of the support member 5. A blocking frame 8 is sleeved on the outer ring of the fixing plate 1. The blocking frame 8 is connected to the fixing plate 1 through a sliding mechanism. This device supports and protects the tool 3 by setting up support members 5 that can move up and down, reducing the possibility of the tool 3 breaking off, without hindering the cutting work of the tool 3, and setting up the blocking frame 8 to prevent the fragments of the broken tool 3 from flying out, making it safe and practical.

[0023] Specifically, the insertion mechanism includes two transverse grooves 9 on the outer wall of the fixed plate 1. The grooves 9 pass through the mounting groove 2. The inner wall of the grooves 9 is laterally slidably fitted with insertion rods 10. The insertion rods 10 movably pass through the cutter 3. The ends of the two insertion rods 10 are fixedly connected by a pulling member 11. An internal groove 12 is provided in the middle of the grooves 9. A fixing piece 13 is fixedly sleeved on the outer wall of the insertion rods 10. The fixing piece 13 is fixedly connected to the inner wall of the internal groove 12 by a second spring 14 movably sleeved on the outer wall of the insertion rods 10. Pulling the pulling member 11 outward causes the insertion rods 10 to move outward against the force of the second spring 14. Pulling the pulling member 11 out of the cutter 3 releases the fixation of the cutter 3, allowing for the disassembly and replacement of the cutter 3.

[0024] More specifically, the sliding mechanism includes a connecting rod 15 that is horizontally fixedly installed on the inner side wall of the barrier frame 8, and a vertical groove 16 is provided on the outer side wall of the fixing plate 1. The connecting rod 15 is slidably connected to the inner side wall of the groove 16, and the barrier frame 8 can move up and down to ensure that the barrier frame 8 will not obstruct the contact between the tool 3 and the pin sleeve.

[0025] Furthermore, multiple mounting parts are fixedly installed on the upper surface of the fixing plate 1. The mounting parts have mounting holes on their upper parts, which facilitates the installation and connection of the device with the cutting machine.

[0026] Furthermore, the barrier frame 8 surrounds the blade 3, and an electromagnetic block 17 is provided on the inner wall of the barrier frame 8. The electromagnetic block 17 can attract the broken and flying fragments of the blade 3 to prevent the fragments of the blade 3 from scattering.

[0027] Working principle:

[0028] In use, the device is installed and connected to the pin sleeve cutting device via the mounting component. The pulling component 11 is pulled outward, which drives the insertion rod 10 to move outward against the force of the second spring 14, pulling the second spring 14 to the other side of the mounting groove 2. Then, the cutter 3 is inserted into the mounting groove 2, so that the cutter 3 abuts against the inner top surface of the mounting groove 2. Then, the pulling component 11 is released, and the second spring 14 pushes the fixing plate 13 to move the insertion rod 10 back to its original position. The insertion rod 10 passes through the cutter 3 to fix the cutter 3. Then, the power of the electromagnetic block 17 is turned on. When the device is cutting, the support component 5 provides support for the cutter 3. When the support component 5 is squeezed by the pin sleeve, the support component 5 moves upward against the force of the first spring 7 to ensure the working space of the cutter 3. When the cutter 3 breaks, the fragments of the cutter 3 that fly out are blocked by the blocking frame 8 and attracted by the electromagnetic block 17 to prevent them from flying out.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
