Description

Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a tooling replacement structure. Background Art

[0002] Chinese patent document CN208759095U discloses a tool replacement device for processing automobile water pump seats, including a body; a screw is installed on the body through a bearing, a pinion is installed on the upper part of the screw, the pinion is meshed with a rack, the middle part of the rack is meshed with an incomplete gear, and a main drive wheel is provided at the rear of the incomplete gear. Two groups of straight tooth groups that are adapted to the rack and the incomplete gear are provided on the arc surface of the main drive wheel. The main drive wheel is connected to a No. 1 motor, and has a high degree of automation. On the basis of utilizing a chain drive to clamp the tool and controlling the forward and reverse alternating rotation of the screw, the two tools can be effectively automatically replaced during the lifting process, which is not only convenient to control, but also plays a positive role in promoting and facilitating the replacement of the tools.

[0003] However, the above-mentioned devices, including some existing devices, have a simple structure for tool replacement and insufficient anti-vibration effect. When the tool is vibrated during operation, it will continuously act on the replacement structure, gradually causing the structure to become loose and shake, resulting in poor stability of the replacement structure. For this reason, we propose a tool replacement structure. Utility Model Content

The top of the base plate is fitted with a connecting plate. At least two groups of reinforcement rods are fixedly installed on the top of the connecting plate. The top of the turntable is provided with positioning holes equal to the number of reinforcement rods. One end of each group of reinforcement rods passes through the U-shaped plate and is inserted into the corresponding positioning hole.

Under the action of the reinforcement mechanism, multiple groups of reinforcement rods are set to replace themselves and the tools to improve the overall stability, improve the shock resistance, and extend the service life of the structure, which solves the problem of some existing devices having a simple structure for tool replacement and insufficient shock resistance. When the tool is subjected to vibration during work, it will continue to act on the replacement structure, gradually causing the structure to become loose and shaken, resulting in poor stability of the replacement structure, thereby improving the practicality of the structure.

[0010] Preferably, the resistance-increasing component includes a fixed block, a connecting rod, a resistance block, a handle and a second spring. The fixed block is fixedly installed on the top of the base plate, and a connecting rod is movably passed through the fixed block.

[0023] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0024] See also Figure 1-3 The utility model provides a technical solution: a tool replacement structure, including a base plate 1, a resistance-increasing component 5 and a reinforcement mechanism 4. A U-shaped plate 2 is fixedly installed on the top of the base plate 1, and a turntable 3 is rotatably installed on the top of the U-shaped plate 2. The resistance-increasing component 5 is arranged on the top of the base plate 1. The resistance-increasing component 5 is used to assist the turntable 3 in positioning during rotation. At least two groups of mounting sleeves 6 are fixedly installed on the top of the turntable 3. Each group of mounting sleeves 6 is provided with a group of mounting holes 7. At least two groups of bolt holes 8 are opened through the base plate 1. A group and at least two groups of positioning lines 9 are respectively opened on the top of the U-shaped plate 2 and the top of the turntable 3.

[0025] The reinforcement mechanism 4 is arranged on the base plate 1 and the U-shaped plate 2. The reinforcement mechanism 4 includes a connecting plate 41 and a reinforcement rod 42. The connecting plate 41 is fitted on the top of the base plate 1. At least two groups of reinforcement rods 42 are fixedly installed on the top of the connecting plate 41. The top of the turntable 3 is provided with positioning holes with a number equal to the reinforcement rods 42. One end of each group of reinforcement rods 42 passes through the U-shaped plate 2 and is inserted into the corresponding positioning hole.

[0026] The reinforcement mechanism 4 also includes a first spring 43 and a handle 44. Each group of reinforcement rods 42 is sleeved with a group of first springs 43. One end of each group of first springs 43 is fixedly connected to the top of the connecting disk 41, and the other end of each group of first springs 43 is fixedly connected to the inner top of the U-shaped plate 2. Two groups of handles 44 are fixedly installed on the outer surface of the connecting disk 41. Through the reinforcement mechanism 4, multiple groups of reinforcement rods 42 are set to replace themselves and the tools to improve the overall stability, improve the shock resistance, and extend the service life of the structure. This solves the problem that some existing devices have a simple structure for tool replacement and insufficient shock resistance. When the tool is subjected to vibration during work, it will continue to act on the replacement structure, gradually causing the structure to become loose and shake, resulting in poor stability of the replacement structure, thereby improving the practicality of the structure.

[0027] The resistance increasing component 5 includes a fixed block 51, a connecting rod 52, a resistance block 53, a handle 54 and a second spring 55. The fixed block 51 is fixedly installed on the top of the base plate 1, and a connecting rod 52 is movably passed through the fixed block 51. A resistance block 53 is fixedly installed on one end of the connecting rod 52, and the resistance block 53 is in conflict with the outer surface of the turntable 3. The other end of the connecting rod 52 is fixedly installed with a handle 54. A second spring 55 is sleeved on the connecting rod 52, and one end of the second spring 55 is fixedly connected to the fixed block 51, and the other end of the second spring 55 is fixedly connected to the handle 54. Through the resistance increasing component 5, a certain resistance can be provided to the rotation of the turntable 3, thereby ensuring the stability of the tool during rotation and position change, and facilitating positioning. At the same time, under the action of the positioning line 9, the accuracy of positioning after position change can be further improved, thereby ensuring the use effect of the structure and being conducive to the promotion and use of the structure.

[0028] Working principle: When installing the tool, place it in each mounting sleeve 6 and install it with bolts through the mounting hole 7. When changing the position of the tool, hold the handle 44 to drive the connecting plate 41 to move up, compress each first spring 43, and drive each reinforcement rod 42 to lift up, so that each reinforcement rod 42 is disengaged from each positioning hole. At this time, the turntable 3 can be rotated. Since the resistance block 53 is against the turntable 3, the turntable 3 rotates slowly until the tool is changed. Then release the handle 44. Under the rebound action of each first spring 43, each reinforcement rod 42 is reset again and inserted into the corresponding positioning hole to fix the turntable 3.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
