Description

Technical Field

[0001] This utility model relates to the field of metal machining technology, and in particular to a lifting device for ring-shaped workpieces and a processing equipment for ring-shaped workpieces. Background Technology

[0002] Grinding is one of the most important steps in industrial machining. After shaping, cutting, and other complex processes, many workpieces will go to this step for further finishing. For parts such as bearing sleeves that require higher concentricity or heavy parts that may affect horizontal machining strategies, vertically oriented grinding machines can provide the necessary stability and accuracy.

[0003] Vertical grinding machines are high-end machine tools with efficient, high-precision, and high-quality grinding capabilities. Their grinding wheel spindle axis is perpendicular to the worktable, making them suitable for grinding the outer cylindrical surfaces of cylindrical and conical workpieces. In the machinery manufacturing industry, they can be used to machine various cylindrical and conical parts, such as shafts, gears, and bearings. In the automotive manufacturing industry, they can be used to machine engine blocks, cylinder liners, and other parts. In the aerospace manufacturing industry, they can be used to machine various high-precision parts, such as turbine blades and shafts. Furthermore, vertical grinding machines can also be used to machine critical components in industries such as hydraulics, sealing, and textiles.

[0004] When machining ring-shaped workpieces using a vertical grinder, the clamping of the workpiece is a crucial factor affecting machining accuracy and a critical step in the process. In traditional clamping methods, operators must manually lift ring-shaped workpieces weighing up to 15kg, with their arms outstretched and body slightly leaning forward, before clamping the workpiece onto the vertical grinder. This method is not only physically demanding and inefficient, but also prone to causing back injuries to the operator. Furthermore, there is a risk of unstable grip causing finger injuries, posing a significant safety hazard.

[0005] Therefore, there is an urgent need to provide a new type of lifting device for ring-shaped workpieces and a processing equipment for ring-shaped workpieces, so as to solve the above-mentioned technical problems in the prior art. Utility Model Content

[0006] One objective of this invention is to provide a lifting device for ring-shaped workpieces, which has the advantages of simple structure and low cost, and can automatically lift the ring-shaped workpieces to be processed, reducing the workload of operators, improving work efficiency, and enhancing the safety of machining operations.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] The ring-shaped workpiece lifting device includes a support rod, a boom, and a lifting assembly. The support rod is fixed to an external equipment platform. One end of the boom is fixed to the top of the support rod, and the other end is provided with a lifting lug. The lifting assembly includes a lifting drive, a claw drive, and multiple lifting claws. The lifting drive is located at the lifting lug. The claw drive is connected to the output end of the lifting drive and is driven to rise and fall by the claw drive. The multiple lifting claws are evenly distributed circumferentially and located at the output end of the claw drive, so that the multiple lifting claws approach each other and grasp the ring-shaped workpiece to be processed.

[0009] Optionally, the aforementioned lifting claw drive includes a drive shaft, a fixed support, and multiple drive links. One end of the drive shaft is connected to the output end of the lifting drive, and the other end is hinged to multiple drive links that are evenly spaced along the circumference. The drive shaft passes through the center of the fixed support, the top of the lifting claw is hinged to the circumferential outer wall of the fixed support, and the drive links are also hinged to the middle of the lifting claw.

[0010] Optionally, the lifting hook includes a handle, an extension, and a hook portion. The handle extends vertically, the extension is vertically connected to the bottom of the handle, and the extension extends away from the drive shaft. The hook portion is connected to the end of the extension away from the drive shaft, and the hook portion is used to grip the ring-shaped workpiece to be processed.

[0011] Optionally, the bottom end of the aforementioned claw portion is provided with a hook tip extending toward the direction of the aforementioned drive shaft, and the top wall of the hook tip is used to abut against the bottom wall of the ring-shaped workpiece to be processed.

[0012] Optionally, the drive linkage is hinged to the connection between the pawl and the extension.

[0013] Optionally, the above-mentioned lifting drive includes a spring balancer.

[0014] Optionally, the driving force of the above-mentioned spring balancer is 6 kg to 15 kg.

[0018] Beneficial effects:

[0019] The ring-shaped workpiece lifting device of this utility model is fixed to an external equipment platform by a support rod. A boom is installed at the top of the support rod, thereby expanding the circumferential lifting space. A lifting lug at the far end of the boom is equipped with a lifting assembly for gripping and lifting the ring-shaped workpiece to be processed, facilitating the operator's movement and clamping of the workpiece.

[0026] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0027] like Figure 1 As shown, the ring-shaped workpiece lifting device includes a support rod 100, a boom 200, and a lifting assembly 300. The support rod 100 is fixed to an external equipment platform. One end of the boom 200 is fixed to the top of the support rod 100, and the other end is provided with a lifting lug. The lifting assembly 300 includes a lifting drive 310, a claw drive 320, and multiple lifting claws 330. The lifting drive 310 is disposed on the lifting lug. The claw drive 320 is connected to the output end of the lifting drive 310 and is driven to rise and fall by the claw drive 320. The multiple lifting claws 330 are evenly distributed circumferentially and disposed on the output end of the claw drive 320, so that the multiple lifting claws 330 approach each other and grasp the ring-shaped workpiece to be processed.

[0028] In this embodiment, the ring-shaped workpiece lifting device is fixed to an external equipment platform by a support rod 100. A boom 200 is provided at the top of the support rod 100, thereby expanding the circumferential lifting space. A lifting lug at the far end of the boom 200 is provided with a lifting assembly 300 for gripping and lifting the ring-shaped workpiece to be processed, thereby facilitating the operator to move and clamp the ring-shaped workpiece to be processed. The lifting assembly 300 specifically includes a lifting drive 310, a claw drive 320, and multiple lifting hooks 330. The lifting drive 310 is used to drive the claw drive 320 and the lifting hooks 330 to rise, thereby lifting the ring-shaped workpiece to be processed. The claw drive 320 drives the multiple lifting hooks 330 to move closer to each other, thereby moving closer to the ring-shaped workpiece to be processed circumferentially, realizing the gripping and fixing of the ring-shaped workpiece to be processed. This ring-shaped workpiece lifting device has the advantages of simple structure and low cost. It can automatically lift the ring-shaped workpiece to be processed, reduce the workload of operators, improve work efficiency, avoid accidents during operation, and improve the safety of machining process.

[0029] Furthermore, the aforementioned lifting claw drive component 320 includes a drive shaft 321, a fixed support 322, and a plurality of drive connecting rods 323. One end of the drive shaft 321 is connected to the output end of the lifting drive component 310, and the other end is hinged to a plurality of drive connecting rods 323 that are evenly spaced along the circumference. The drive shaft 321 passes through the center of the fixed support 322. The top of the lifting claw 330 is hinged to the circumferential outer wall of the fixed support 322, and the drive connecting rods 323 are also hinged to the middle of the lifting claw 330. During operation, the operator first places multiple lifting claws 330 at the bottom of the ring-shaped workpiece to be processed. At this time, the operator manually or using the lifting drive component 310 lifts the drive shaft 321 upwards. The drive shaft 321 then drives the drive linkage 323 to rotate. The rotation of the drive linkage 323 will cause the lifting claws 330 to rotate along the hinged part at their top, so that the bottom of the lifting claws 330 moves closer to the ring-shaped workpiece to be processed, allowing the multiple lifting claws 330 to grab and fix the ring-shaped workpiece to be processed.

[0030] Specifically, the aforementioned lifting claws 330 are evenly arranged in three circumferential directions, which will not be described in detail here.

[0031] In this embodiment, the lifting hook 330 includes a handle 331, an extension 332, and a hook portion 333. The handle 331 extends vertically, the extension 332 is vertically connected to the bottom of the handle 331, and extends away from the drive shaft 321. The hook portion 333 is connected to the end of the extension 332 away from the drive shaft 321. The hook portion 333 is used to grip the ring-shaped workpiece to be processed. The handle 331 and the extension 332 enable the ring-shaped workpiece lifting device to be applicable to ring-shaped workpieces of different diameters and heights, and also facilitate personnel operation, thus improving its applicability and ease of use.

[0032] Optionally, the bottom end of the aforementioned claw portion 333 is provided with a hook tip 334 extending toward the drive shaft 321, and the top wall of the hook tip 334 is used to abut against the bottom wall of the ring-shaped workpiece to be processed. The hook tip 334 can support the bottom wall of the ring-shaped workpiece to be processed, preventing the ring-shaped workpiece from falling off during lifting and transportation, thereby improving the reliability and safety of use.

[0033] Please continue to refer to this. Figure 1 The aforementioned drive link 323 is hinged at the connection point between the aforementioned claw handle 331 and the aforementioned extension 332. This arrangement allows the distance between the connection point of the drive link 323 and the lifting claw 330 and the hinge point at the top of the lifting claw 330 to be as large as possible. Under the leverage effect, the drive link 323 can apply a greater driving force to the lifting claw 330 without affecting the claw portion 333 of the lifting claw 330 in gripping the ring-shaped workpiece to be processed, thus improving convenience.

[0034] In this embodiment, the lifting drive component 310 includes a spring balancer. A spring balancer is an auxiliary tool used in conjunction with operating tools. It uses a coil spring to put the suspended load in a weightless state. It is suitable for most situations where manual tools and lifting equipment are used, such as when the workload is concentrated or the operating tools are heavy and need to be used repeatedly for a long time. Its structure is simple and easy to produce, and the cost is lower when used in batches or purchased.

[0035] Optionally, the driving force of the aforementioned spring balancer is 6 kg to 15 kg. In this embodiment, the weight of the ring-shaped workpiece to be processed is approximately 15 kg, therefore a self-locking spring balancer is used, with a load between 1 kg and 15 kg and adjustable; if the weight of the ring-shaped workpiece is too large, a common spring balancer can be used, with a load between 5 and 160 kg, which will not be elaborated here.

[0036] In this embodiment, the height of the support rod 100 is adjustable. Specifically, the adjustable height of the support rod 100 allows the ring-shaped workpiece lifting device to be suitable for lifting needs at different heights, expanding its applicability and making it more convenient to use; further details will not be elaborated here.

[0037] Specifically, the support rod 100 in this embodiment can also be configured as a non-adjustable segmented design, which is composed of a round steel with a length of 250mm and a diameter of 45mm at the bottom and a round steel with a diameter of 40mm and a length of 500mm at the top. The boom 200 is made of round steel with a diameter of 40mm and a length of 350mm.

[0038] Optionally, the above-mentioned ring-shaped workpiece lifting device further includes a fixed base 110, the bottom wall of the support rod 100 is fixed to the fixed base 110, and the fixed base 110 is detachably fixed to the external equipment platform via a connector 111. In this embodiment, the base size is 200mm × 150mm, the external equipment platform is the protective door frame of a vertical grinding machine, and the installation position of the base can be adjusted according to requirements. The base provides installation support for the ring-shaped workpiece lifting device, ensuring the stability of the installation; in order to ensure the free rotation of the support rod 100 around its own axis, an adjusting rod is also provided on the base, the support rod 100 passes through the adjusting rod and is rotatably connected to the adjusting rod.

[0039] In this embodiment, the connector 111 is specifically a fixing bolt, which has a better fixing effect and is easy to disassemble, thus improving the ease of maintenance of the ring-shaped workpiece lifting device.

[0040] This embodiment also provides a ring-shaped workpiece processing device, which includes a ring-shaped workpiece lifting device as described in any of the above embodiments. Specifically, this ring-shaped workpiece processing device is a vertical grinder, possessing high-efficiency, high-precision, and high-quality grinding capabilities. Its grinding wheel spindle axis is perpendicular to the worktable, making it suitable for grinding the outer cylindrical surface of ring-shaped, cylindrical, and conical workpieces. This ring-shaped workpiece processing device uses the ring-shaped workpiece lifting device as described in any of the above embodiments to grip and lift the ring-shaped workpiece, thereby achieving all the beneficial effects of the ring-shaped workpiece lifting device described in any of the above embodiments. Specifically, it can automatically lift the ring-shaped workpiece to be processed, reduce the workload of the operator, improve work efficiency, avoid operator injuries during the work process, and improve the safety of the machining operation process.
