A processing device for trolley wheels

Abstract

This utility model discloses a processing device for handcart wheels, including a platform. A first double-ended screw is rotatably connected to the platform. One end of the first double-ended screw is threadedly connected to a first rod body. Grooved wheels are rotatably connected to both first rod bodies. A second rod body is provided at one end of the platform and a grinding disc is provided at each of the two second rod bodies. This utility model utilizes the first double-ended screw to drive the two first rod bodies to move synchronously outwards or inwards, thereby adjusting the spacing between the two rows of grooved wheels. When the two rows of grooved wheels approach each other, the symmetrical pressure of the circular wheel forces the wheel to automatically center itself. Positioning and installation of the handcart wheel is relatively convenient, requiring no replacement, thus ensuring processing efficiency and avoiding delays in handcart production.

Description

Technical Field

[0001] This utility model relates to the technical field of handcarts, and in particular to a processing device for handcart wheels. Background Technology

[0002] A handcart is a lightweight transport tool, typically consisting of a frame, wheels, and a handle, with a simple and flexible structure. It comes in various types based on the number of wheels, including single-wheeled, two-wheeled, three-wheeled, and four-wheeled models, and is made from materials such as metal and plastic. Widely used in warehousing, logistics, homes, supermarkets, and other scenarios, it is characterized by low cost, ease of operation, and adaptability to various goods handling needs. It effectively improves short-distance transportation efficiency and is a common auxiliary tool in production and daily life.

[0003] Although existing handcart wheel processing devices can grind handcart wheels, traditional devices mostly use fixed clamps or cumbersome bolt fastening methods. When facing wheels of different specifications (such as wheel diameter differences) for positioning and centering, operators need to repeatedly adjust the clamp spacing or replace the appropriate parts. The replacement is relatively time-consuming, which will affect the processing efficiency and thus delay the production progress of handcarts. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a processing device for handcart wheels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A processing device for handcart wheels includes a platform, a first double-ended screw rotatably connected to the platform, a first rod body threadedly connected to one end and the other end of the first double-ended screw, a grooved wheel rotatably connected to each of the two first rod bodies, a second rod body provided at one end and the other end of the platform, and a grinding disc provided at each of the two second rod bodies.

[0007] Preferably, a second double-ended screw is rotatably connected to the platform, and the second double-ended screw is threadedly connected to two second rod bodies.

[0008] Preferably, studs are connected to the two second rods, and the two studs pass through the shaft holes of the corresponding grinding discs. Threaded sleeves are threaded to the two studs, and the two threaded sleeves are in contact with the corresponding grinding discs.

[0009] Preferably, two sliding rods are connected to the platform, and the two sliding rods are slidably connected to the two first rods.

[0010] Preferably, a motor is installed at one of the first rods, and the output end of the motor is connected to the corresponding grooved wheel.

[0011] Preferably, a slide rail is connected to the platform, the slide rail is slidably connected to the two second rods, and a second handle is connected to the first double-ended screw.

[0012] Preferably, a first handle is connected to the second double-ended screw.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By coordinating the platform, the first double-ended screw, the first rod, and the grooved wheels, the first double-ended screw drives the two first rods to move outward or inward simultaneously, thus adjusting the spacing between the two rows of grooved wheels. When the two rows of grooved wheels approach each other, the symmetrical pressure of the two rows of grooved wheels, due to the circular shape of the wheels, forces the wheels to automatically center themselves. The positioning and installation of the hand-pushed wheels are relatively convenient and do not require replacement, thereby ensuring processing efficiency and avoiding delays in the production progress of the handcart.

[0015] 2. By coordinating the second double-ended screw, the second rod body, and the grinding wheel, the rotation of the second double-ended screw can drive the two second rod bodies to move outwards or inwards simultaneously, so that the two sets of grinding discs can contact one end and the other end of the push wheel respectively. With one rotation, the push wheel can perform two grinding operations, which can improve grinding efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 A processing device for a handcart wheel includes a platform 1, with a first double-ended screw 2 rotatably connected to the platform 1. One end of the first double-ended screw 2 is threadedly connected to a first rod 3. The first double-ended screw 2 is symmetrically machined with left- and right-hand threads, and both ends are connected to the two first rods 3 via threaded pairs. When a second handle 14 is rotated, the rotational motion of the first double-ended screw 2 is converted into synchronous linear motion of the two first rods 3 in the same or opposite directions. Each of the two first rods 3 is rotatably connected to a grooved wheel 4, the surface of which is machined with an arc groove to fit the outer contour of a round wheel. The grooved wheel 4 is rotatably connected to the first rod 3 via bearings, allowing the grooved wheel 4 to rotate synchronously when the wheel rotates, reducing friction loss. A second rod 6 is provided at one end of the platform 1, and a grinding disc 10 is provided at each of the two second rods 6. By adjusting the spacing between the two rows of grooved wheels 4, the handcart wheel between the two rows of grooved wheels 4 can be easily positioned and fixed in the center.

[0024] In this embodiment, a second double-ended screw 8 is rotatably connected to the platform 1. The second double-ended screw 8 also adopts a left- or right-hand thread design, with both ends threadedly connected to two second rods 6. When the first handle 7 is rotated, the two second rods 6 on both sides can be driven to move equidistantly in opposite directions. The second double-ended screw 8 is threadedly connected to the two second rods 6, and studs 9 are connected to the two second rods 6. The two studs 9 pass through the shaft holes of the corresponding grinding discs 10. Threaded sleeves 11 are threadedly connected to both studs 9, and the two threaded sleeves 11 contact the corresponding grinding discs 10. By removing the threaded sleeves 11 from the grinding discs 10 and separating them from the studs 9, the grinding discs 10 can be disassembled and replaced. Two double-ended screws are connected to the platform 1. Slide rod 12, two slide rods 12 are slidably connected to two first rod bodies 3, ensuring that the first rod body 3 moves only along the first double-ended screw 2, screw axis during the movement, avoiding rotational shaking. A motor 5 is installed at one of the first rod bodies 3. The model of the motor 5 is selected according to the actual working requirements. The output end of the motor 5 is connected to the corresponding groove wheel 4. A slide rail 13 is connected to the platform 1. The slide rail 13 is slidably connected to two second rod bodies 6. A second handle 14 is connected to the first double-ended screw 2. A first handle 7 is connected to the second double-ended screw 8.

[0025] The working principle of this embodiment is as follows: When in use, the hand-push wheel is placed between the two rows of grooved wheels 4. At the same time, the first double-ended screw 2 is rotated using the second handle 14. The first double-ended screw 2 can drive the two first rods 3 to move closer to each other. This allows the two rows of grooved wheels 4 to contact one end and the other end of the hand-push wheel. The symmetrical pressure of the grooved wheels 4 will force the wheel to automatically center itself. After centering, the second double-ended screw 8 is rotated using the first handle 7, which moves the two sets of second rods 6 closer to each other. This allows the two grinding discs 10 to contact one end and the other end of the hand-push wheel. The motor 5 is connected to an external power source and drives one set of grooved wheels 4 as the active drive and the other grooved wheels 4 as the driven drive. This allows the hand-push wheel to rotate, making the hand-push wheel contact the two sets of grinding discs 10, and thus perform the grinding operation.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
