Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a fixture for a bench drill. Background Technology

[0002] A drilling machine is a machine tool that primarily uses a drill bit to machine holes in a workpiece. Typically, the rotation of the drill bit is the main motion, and the axial movement of the drill bit is the feed motion. Drilling machines have a simple structure and relatively low machining accuracy. They can drill through holes and blind holes. By changing special tools, they can also perform reaming, counterboring, boring, or tapping. During machining, the workpiece remains stationary while the tool moves, aligning its center with the hole center and rotating (the main motion). The key characteristic of a drilling machine is that the workpiece is stationary while the tool rotates and feeds along the spindle. Operation can be manual or motorized.

[0003] Application number CN202323079788.3 discloses a positioning fixture for a drilling machine, including a base plate and other structures. Two sets of first threaded rods are driven to rotate by the output shafts at both ends of a dual-axis motor. Under the action of two sets of first limiting grooves and two sets of first limiting blocks, two sets of moving plates can move, thereby causing two sets of fixed plates to move. Adjusting the distance between the two sets of fixed plates allows the two sets of clamping plates to clamp and fix the workpiece. This eliminates the need for manual workpiece positioning by the worker, making it simpler and more convenient, and improving processing efficiency to some extent. However, in practical use, the workpiece cannot be drilled continuously, resulting in lower production efficiency. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A fixture for a bench drill includes a feeding mechanism, a clamping mechanism, and a linkage mechanism. The feeding mechanism includes a base and a belt conveyor embedded in the top of the base. The clamping mechanism includes two guide plates on the top of the base, a hydraulic cylinder connected to the top of the guide plates, and a pressure plate connected to the movable end of the hydraulic cylinder. The guide plates have openings suitable for the pressure plate to pass through. The two hydraulic cylinders are connected in series. The linkage mechanism includes a rod connected to the movable end of one of the hydraulic cylinders, a tactile switch abutting the outer end of the rod, and a support plate connected between a guide plate and the tactile switch. The tactile switch is electrically connected to the belt conveyor.

[0007] By adopting the above technical solution, each time the movable ends of the two hydraulic cylinders extend and retract, the rod that moves with one hydraulic cylinder presses against the tactile switch, and then the belt conveyor is started and transports the blank. When a single blank arrives between the two pressure plates, the movable end of the hydraulic cylinder is already in the extended state, and the corresponding rod separates from the tactile switch. The belt conveyor is then de-energized. Then, while the two pressure plates clamp the blank, the drilling machine processes the blank. The above steps are then repeated, thereby achieving continuous processing and improving production efficiency.

[0008] In a preferred embodiment, the present invention can be further configured such that: a plurality of insert plates are installed at the bottom of the guide plate, and the plurality of insert plates are arranged in a matrix.

[0009] In a preferred embodiment, the present invention can be further configured such that: the top of the base has multiple sockets suitable for inserting the insert plate, and the multiple sockets are equally spaced and arranged in two columns.

[0010] In a preferred embodiment, the present invention can be further configured such that: two bolts are screwed onto the base, and the two bolts are respectively located on the outer sides of the two guide plates.

[0011] In a preferred embodiment, the present invention can be further configured such that: both sides of the pressure plate are provided with reinforcing ribs, and the reinforcing ribs are detachably connected to the guide plate.

[0012] In a preferred embodiment, the present invention can be further configured such that the rod is shaped like a "﹁" and is suspended from the top of the guide plate cylinder.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, each time the movable ends of the two hydraulic cylinders extend and retract, the rod that moves with one hydraulic cylinder presses against the tactile switch, and then the belt conveyor is started and transports the blank. When a single blank arrives between the two pressure plates, the movable end of the hydraulic cylinder is already in the extended state, and the corresponding rod separates from the tactile switch. The belt conveyor is de-energized, and then while the two pressure plates clamp the blank, the drilling machine processes the blank. Then the above steps are repeated, thereby achieving continuous processing and improving production efficiency.

[0015] 2. In this utility model, the positions of the two guide plates are flexibly adjusted according to the size of the blank to be drilled, with the cooperation of the insert plate and the socket, so that the blank moves just between the two guide plates, ensuring that the pressure plate can quickly clamp the blank, which can adapt to blanks of any size and improve the applicability of this device.

The guide plates 210 have openings suitable for the pressure plate 230 to pass through, and the two hydraulic cylinders 220 are connected in series.

[0034] The linkage mechanism 300 includes a rod 310 connected to the movable end of a hydraulic cylinder 220, a tactile switch 320 attached to the outer end of the rod 310, and a support plate 330 connected between a guide plate 210 and the tactile switch 320. The tactile switch 320 is electrically connected to the belt conveyor 120.

[0035] Furthermore, the pressure plate 230 is provided with reinforcing ribs on both sides, and the reinforcing ribs are detachably connected to the guide plate 210. The reinforcing ribs can improve the structural strength of the guide plate 210.

[0036] Furthermore, the rod 310 is configured in the shape of a "﹁" and is suspended above the cylinder body of the guide plate 210. The shape and layout design of the rod 310 ensures that it will not rub against the guide plate 210 when it moves, thus preventing abnormal noise and ensuring a comfortable working environment.

[0037] Example 2:

[0038] Combination Figure 1-3 and Figure 5 As shown, based on Embodiment 1, the bottom of the guide plate 210 is equipped with multiple insert plates 400, which are arranged in a matrix. The insert plates 400 provide conditions for the connection between the guide plate 210 and the base 110.

[0039] Furthermore, the top of the base 110 is provided with multiple insertion ports 500 suitable for insertion of the insertion plate 400. The multiple insertion ports 500 are equally spaced and arranged in two columns. The insertion ports 500 provide conditions for flexibly adjusting the position of the guide plate 210, so that the device can adapt to blanks of any size.

[0040] Example 3:

[0041] Combination Figure 1 As shown, in the above embodiment, two bolts 600 are screwed onto the base 110. The two bolts 600 are located on the outside of the two guide plates 210 respectively. The bolts 600 are provided to facilitate the connection of the base 110 to an external drilling machine.

[0042] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the base 110 is connected to the external drilling machine through two bolts 600. Then, according to the width of the blank to be processed, the distance between the two guide plates 210 is adjusted. Then, the belt conveyor 120 sends the blank between the two pressure plates 230. Then, the two hydraulic cylinders 220 control the two pressure plates 230 to clamp the blank. Then, the drilling machine processes the blank. After that, the movable ends of the two hydraulic cylinders 220 are controlled to retract. Then, the rod 310 that follows the movement of one hydraulic cylinder 220 moves towards the tactile switch 320 and makes contact. Then, the belt conveyor 120 is started, and the blank to be processed is conveyed forward. Then, the formed workpiece is pushed away. Then, the above steps are repeated to achieve continuous processing and improve processing efficiency.
