AI Technical Summary
In the production of existing teeth cutters, the inclined rail guidance causes the robot to only operate on the alloy head part when loading, which increases clamping difficulty and instability.
An automated feeding positioning tool is designed, including a obliquely arranged toothed rail and a toothed hoisting device. The toothed seat part protrudes from the guide rail through a motor-driven pin, increasing the operating space and stability of the robot.
It improves the clamp stability of the robot to the teeth and reduces safety risks during the conveying process.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of pick production devices, in particular to an automatic feeding and positioning tool for pick production. Background Art
[0002] Picks are special tools used for cutting and digging, and are widely used in mining, tunnel construction, construction, railway engineering and other fields. The manufacturing of picks requires multiple processes and processes, including material selection, forging, heat treatment, machining, etc. Picks are mainly composed of a tooth seat and an alloy head on the upper end of the tooth seat.
[0003] After the pick is formed, in order to ensure that it meets the requirements of use, it also needs to be aligned, heat treated and further machined. Currently, these steps are generally carried out by guiding the pick to the corresponding position through an inclined guide rail during loading, and then clamping it to the corresponding processing position through a robot. However, in actual use of this loading method, due to the limitations of the guide rail, the alloy head of the pick is close to the upper end of the guide rail, which results in the robot being able to operate only on the alloy head part of the pick when working. Due to the special structure of the alloy head, this increases the difficulty of clamping by the robot, and there is a risk of unstable clamping. In this regard, the present application specifically proposes an automated loading and positioning tooling for pick production to solve the above problems. Summary of the invention
[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an automatic loading and positioning tooling for pick production, and the technical solution to the problem is to include a manipulator body, characterized in that a bottom plate is arranged on the right side of the manipulator body, a plurality of brackets are fixedly connected to the upper end of the bottom plate, the brackets are fixedly connected to a pick guide rail, the pick guide rail is arranged obliquely to the lower left, and the bottom plate is connected to a pick lifting device; The pick lifting device includes a mounting block fixedly connected to a base plate, a guide rod arranged perpendicular to the pick guide rail fixedly connected to the upper end of the mounting block, a support plate fixedly connected to the upper end of the guide rod, an active rod arranged parallel to the guide rod rotatably connected to the support plate and the mounting block, a screw rod coaxially arranged on the active rod, a lifting rod slidably connected to the screw rod, a lifting rod fixedly connected to a jack rod, a motor for driving the active rod fixedly connected to the support plate, and a controller electrically connected to the motor is mounted on the base plate.
[0005] Preferably, the lifting rod is integrally provided with a guide sleeve slidably connected to the guide rod, and the lifting rod is integrally provided with a threaded sleeve matched with the thread of the screw rod.
[0006] The beneficial effects of the present invention are: Specifically, when the present application is in use, the pick consists of two parts: an alloy head and a tooth seat. The pick guide rail is arranged obliquely, so that the pick can automatically move to the lower left end along the pick guide rail under its own weight. The pick lifting device corresponds to the lower left end of the pick guide rail. The push rod of the pick lifting device can move upward under the drive of the motor, thereby driving the push rod to move upward and abut under the pick (specifically the pick at the lower left end of the pick guide rail), and then the push rod drives the pick to move upward, so that the tooth seat part of the pick protrudes from the pick guide rail, and then the contact part of the manipulator body with the pick is greatly increased, which is convenient for the manipulator body to clamp the pick, ensure the stability of the clamping, and greatly reduce the stability of the manipulator body clamping and conveying the pick.

[0012] The following is combined with Figure 1-4 The specific implementation modes of the present invention are further described in detail.
[0013] Embodiment 1, the technical solution is, specifically, when the present application is in use, the pick is composed of an alloy head 17 and a tooth seat 18. The pick guide rail 4 is arranged obliquely, so that the pick automatically moves to the lower left end along the pick guide rail 4 under its own weight. The pick lifting device 5 corresponds to the lower left end of the pick guide rail 4. The push rod 12 of the pick lifting device 5 can move upward under the drive of the motor 13, thereby driving the push rod 12 to move upward and abut under the pick (specifically the pick at the lower left end of the pick guide rail 4), and then the push rod 12 drives the pick to move upward, so that the tooth seat 18 of the pick protrudes from the pick guide rail 4, and then the contact part of the manipulator body 1 with the pick is greatly increased, which is convenient for the manipulator body 1 to clamp the pick, ensure the stability of the clamping, and greatly reduce the stability of the manipulator body 1 in clamping and conveying the pick.
[0014] Embodiment 2, based on embodiment 1, specifically, when the present application is in use, the manipulator body 1 provided can adopt the existing technology, and the manipulator body 1 can be flexibly moved with the corresponding control system, so as to clamp and move the pick on the pick guide rail 4, which is not described in detail in the present application. In the present application, the pick guide rail 4 is installed above the base plate 2 through the bracket 3, and the pick guide rail 4 is arranged obliquely to the lower left, so that the pick automatically moves downward along the guide rail under its own gravity.
[0015] If the drawings in the specification Figure 1 As mentioned above, it is a common phenomenon that the alloy head 17 of the pick is partially abutted against the top of the pick guide rail 4. This results in the manipulator body 1 being able to clamp only the alloy head 17 part, which makes clamping difficult. In this regard, the present application specially proposes a pick lifting device 5. The controller 14 of the pick lifting device 5 can control the motor 13 to rotate forward and reverse according to a set cycle so as to match it with the action cycle of the manipulator. When the controller 14 controls the motor 13 to rotate forward, the motor 13 will drive the active rod 9 connected between the support plate 8 and the mounting block 6 to rotate clockwise. The clockwise rotation of the active rod 9 will act on the lifting rod 11 through the screw 10 arranged integrally therewith, and the lifting rod 11 is threadedly connected to the screw 10 through the threaded sleeve 16. At the same time, the lifting rod 11 is also slidably connected to the guide rod 7 through the guide sleeve 15. Then, when the active rod 9 rotates clockwise under the drive of the motor 13, the screw 10 arranged integrally with the active rod 9 will drive the lifting rod 11 to move upward along the guide rod 7, and then the push rod 12 fixedly connected to the guide rod 7 will also move upward synchronously, and then the push rod 12 will be pushed under the lower left end of the pick, thereby driving the pick to move upward, thereby making the tooth seat 18 of the pick protrude from a part of the pick guide rail 4, and then the manipulator body 1 can have a larger operating space for the pick, which greatly reduces the difficulty of clamping, facilitates the stable clamping of the pick by the manipulator body 1, and reduces safety hazards.
[0016] Correspondingly, after the robot body 1 clamps and moves the pick, the controller 14 controls the motor 13 to reverse. The reversal of the motor 13 will drive the active rod 9 and the screw rod 10 to reverse synchronously, and then drive the lifting rod 11 and the push rod 12 to reset. When the push rod 12 is reset, the pick in the pick guide rail 4 will automatically move downward, thereby filling the position of the pick moved away by the robot body 1, so as to facilitate the next action of the robot body 1.
