Description

Technical Field

[0001] This utility model relates to the field of loading technology for exchange worktables, and in particular to an automatic loading tray for exchange worktables. Background Technology

[0002] To improve processing efficiency, existing machine tools mostly adopt automated control methods. However, in actual operation, because the machine tool can only process one workpiece at a time and cannot prepare a place for the next workpiece on the machine tool, there cannot be any extra workpieces on the machine tool during the processing of one workpiece. Currently, material is mostly transported by conveyor belts. In fact, to avoid material accumulation due to excessively fast transport speed, the conveyor belt is temporarily shut down during the processing.

[0003] The above methods severely limit the material feeding efficiency and processing methods of machine tools, especially causing serious interference to material preparation, which often makes the material preparation cycle longer than the processing cycle. Moreover, the workpiece needs to be repeatedly tightened and loosened during the transmission and processing process, which not only affects the feeding efficiency but also the processing accuracy, making it extremely difficult to have an advantage in processing and production. Utility Model Content

[0004] The purpose of this invention is to solve the problem of inefficient material conveying in the prior art, which affects processing efficiency, and proposes an automatic feeding tray for the exchange workbench.

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

[0006] The automatic feeding tray of the exchange workbench includes a machine base, with a feeder and a processing machine respectively arranged on the left and right sides of the machine base, and a feeding mechanism for step-by-step conveying of materials from the feeder to the processing machine arranged in the middle of the machine base.

[0007] Preferably, the feeding mechanism is located between the feeder and the processing machine.

[0008] Preferably, the feeding mechanism includes:

[0009] A transfer fixture is used to receive materials from the feeder and horizontally transfer them to the processing position of the corresponding processing machine.

[0010] The receiving fixture consists of two sets, which are symmetrically arranged at the front and rear ends of the transfer fixture. The receiving fixture is used to fix the material of the horizontal transfer and the corresponding processing machine.

[0011] A material pushing fixture is provided on a transfer fixture and is located between two sets of receiving fixtures. The material pushing fixture is used to push materials to one side of the processing machine.

[0012] Preferably, the transfer fixture includes a guide groove located at the center of the machine tool, a load-bearing sleeve with a ratchet assembly on its inner wall is movably installed in the guide groove, and a drive disc located in the load-bearing sleeve is rotatably installed in the machine tool. A drive key that movably abuts against the ratchet assembly is installed on the drive disc, and a strong spring for elastically pulling the drive key is fixedly provided on the drive disc.

[0013] Preferably, the receiving fixture includes a load-bearing column fixedly mounted on the load-bearing sleeve and having a hollow structure. A load-bearing plate for vertically placing materials is integrally connected to the load-bearing column, and a vertically lifting drive slider is slidably mounted in the load-bearing column. Steering levers that are movably pulled by the drive slider are installed on pins on both sides of the load-bearing plate. Clamping components that are movably pulled by the steering levers and used to clamp materials in opposite directions are slidably mounted on the load-bearing plate.

[0014] Preferably, the pushing fixture includes a T-shaped bracket fixedly mounted on a load-bearing sleeve, a drive gear is rotatably mounted in the T-shaped bracket, and a reciprocating rack meshing with the drive gear is slidably mounted in the T-shaped bracket, with push plates threadedly connected to both ends of the reciprocating rack.

[0015] Preferably, a traction link is connected between the drive slider and the lower end of the steering lever via a pin shaft, and a traction elongated hole is provided in the upper end of the steering lever, and a traction bolt is integrally connected to the clamping member and slidably fitted in the traction elongated hole.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This utility model has a feeding mechanism located in the middle of the machine base between the feeder and the processing machine, which allows the material to be prepared in a step-by-step manner according to the processing needs. The preparation of the next material is realized during the processing of one material, which helps to shorten the material preparation cycle and improve processing efficiency. The concentrically distributed drive disc and load-bearing sleeve are used, so that the load-bearing sleeve can be driven by the drive key to support the tooling to rotate 90° each time.

[0018] 2. This utility model sets two sets of symmetrically distributed receiving fixtures on the load-bearing sleeve. The receiving fixtures use a driving slider to pull and drive the symmetrically distributed clamping parts, so as to stabilize and limit the material located on the load plate.

[0019] 3. This utility model provides a material pushing fixture located between two sets of receiving fixtures on the load-bearing sleeve. The material is horizontally pushed on the set of receiving fixtures facing the processing machine by means of the meshing connection between the drive gear and the reciprocating rack.

[0032] 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.

[0033] Reference Figures 1-6The automatic feeding tray of the exchange workbench includes a machine base 1. A feeder 2 and a processing machine 3 are respectively set on the left and right sides of the machine base 1. A feeding mechanism 4 for step-by-step conveying of materials from the feeder 2 to the processing machine 3 is set in the middle of the machine base 1. It should be noted that by setting the feeding mechanism 4, the next material can be prepared while processing one material, reducing the preparation time. The processing machine 3 is movably installed on the machine base 1 via a slide rail, so that its position can be adjusted according to processing needs.

[0034] The feeding mechanism 4 is located between the feeder 2 and the processing machine 3, which enables seamless material conveying between the feeder 2 and the processing machine 3, avoiding inefficiency caused by long material preparation cycles between the two processing steps.

[0035] The feeding mechanism 4 includes a transfer fixture 41, a receiving fixture 42, and a pushing fixture 43.

[0036] The transfer fixture 41 is used to receive materials from the feeder 2 and horizontally transfer them to the corresponding processing position on the processing machine 3. See the attached instruction manual for details. Figure 3 With appendix Figure 4 The transfer fixture 41 includes a guide groove 411 located at the center of the machine base 1. A load-bearing sleeve 412 with a ratchet assembly on its inner wall is movably installed in the guide groove 411. A drive disc 413 located in the load-bearing sleeve 412 is rotatably installed in the machine base 1. A drive key 414 that movably abuts against the ratchet assembly is mounted on the drive disc 413. A strong spring 415 for elastically pulling the drive key 414 is fixedly installed on the drive disc 413. It should be noted that the machine base 1 The drive motor is provided to control the rotation of the drive disk 413. The drive motor controls the drive disk 413 to reciprocate 90°. When the drive disk 413 rotates clockwise, the drive key 414 causes the strong spring 415 to contract and not put pressure on the ratchet assembly. When the drive disk 413 rotates counterclockwise, the elastic support of the strong spring 415 causes the drive key 414 to engage with the ratchet assembly, thereby driving the load-bearing sleeve 412 to rotate.

[0037] There are two sets of receiving fixtures 42, which are symmetrically arranged at the front and rear ends of the transfer fixture 41. The receiving fixtures 42 are used to fix the horizontal transfer and the corresponding processing machine 3 materials. Please refer to the appendix of the instruction manual for details. Figure 5The receiving fixture 42 includes a hollow load-bearing column 421 fixedly mounted on the load-bearing sleeve 412. A load-bearing plate 422 for vertically placing materials is integrally connected to the load-bearing column 421. A vertically lifting drive slider 423 is slidably mounted in the load-bearing column 421. A drive cylinder for controlling the vertical lifting of the drive slider 423 is provided in the load-bearing column 421. A steering lever 424, which is movably pulled by the drive slider 423, is mounted on the two sides of the load-bearing plate 422. Clamping members 425, which are slidably pulled by the steering lever 424 and used to clamp materials in opposite directions, are symmetrically arranged on the load-bearing plate 422. The clamping members 425 move in opposite directions under the traction of the steering lever 424 to clamp and fix the materials located on the load-bearing plate 422.

[0038] The pushing fixture 43 is mounted on the transfer fixture 41 and is located between the two sets of receiving fixtures 42. The pushing fixture 43 is used to push materials to one side of the processing machine 3. For details, please refer to the appendix of the instruction manual. Figure 6 The material pushing fixture 43 includes a T-shaped bracket 431 fixedly mounted on the load-bearing sleeve 412. A drive gear 432 is rotatably mounted in the T-shaped bracket 431, and a reciprocating rack 433 meshing with the drive gear 432 is slidably mounted in the T-shaped bracket 431. Push plates are threadedly connected to both ends of the reciprocating rack 433. It should be noted that a drive motor controlling the rotation of the drive gear 432 is provided on the T-shaped bracket 431. The reciprocating rack 433, which moves linearly and reciprocally, applies pressure to the material located on the load plate 422 through the push plates, so as to facilitate unloading from the receiving fixture 42.

[0039] Please refer to the instruction manual for details. Figure 5 A traction link 426 is connected between the drive slider 423 and the lower end of the steering lever 424 by a pin. A traction hole 427 is opened in the upper end of the steering lever 424, and a traction bolt 428 is integrally connected to the clamping member 425 and slidably fitted in the traction hole 427. Under the driving action of the drive slider 423, the two clamping members 425 move synchronously.

[0040] It should be noted that the specific models and specifications of the feeder 2 and the processing machine 3 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0041] The functional principle of this utility model can be explained through the following operation methods:

[0042] Control the drive disc 413 to rotate 90° clockwise. Because the strong spring 415 contracts, the drive key 414 retracts and latches into the predetermined position of the ratchet assembly. Then control the drive disc 413 to rotate 90° counterclockwise. Because of the elastic support of the strong spring 415, the drive key 414, which is latched into the ratchet assembly, drives the load-bearing sleeve 412 to rotate 90° synchronously.

[0043] When the feeder 2 conveys the material to the load plate 422, it controls the drive slider 423 to move vertically downward, and uses the traction link 426 to squeeze the lower end of the steering lever 424. The deflected steering lever 424 drives the clamping member 425 to move horizontally through the traction hole 427 and the traction bolt 428, so as to clamp and limit the material on the load plate 422.

[0044] When the receiving fixture 42 rotates the material to the corresponding processing position of the processing machine 3, the processing machine 3 is finely adjusted to process the material.

[0045] After processing is completed, the drive gear 432 is rotated, and the reciprocating rack 433 drives the push plate to push the processed material horizontally.

[0046] 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.
