Description

Technical Field

[0001] This utility model relates to the field of drilling and cutting machine design technology, and in particular to a small mandrel drilling and cutting machine capable of continuous processing. Background Technology

[0002] A mandrel is a shaft component used to assemble and support other parts. It typically has high precision and specific surface contact strength to meet assembly and usage requirements. During mandrel processing, drilling and cutting are required for subsequent use, thus necessitating the use of a drilling and cutting machine. During processing, the mandrel is fixed in a feeding fixture and moved towards the drill bit. Then, when the motor starts, the spindle begins to rotate, and the drill bit rotates accordingly and cuts into the workpiece. By adjusting the spindle speed, feed rate, and drill bit type, processing requirements for different materials and hole diameters can be met.

[0003] The applicant's search revealed that most existing drilling and cutting machines are single-station designs, such as the core drilling and turning machine tool announced in CN210080739U. This requires frequent changes of the workpiece, resulting in low processing efficiency. While some existing improved machine tools use a multi-station rotary design, their structures are complex and require expensive braking mechanisms to control the speed of rotating parts or to stop them. This complexity makes maintenance and upkeep difficult. For example, it may be necessary to disassemble multiple parts to access the braking components for inspection and replacement, which increases maintenance time and costs.

[0004] Therefore, the applicant proposes a small mandrel drilling and cutting machine capable of continuous processing to solve the problem. Utility Model Content

[0022] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-5 This utility model provides a small mandrel drilling and cutting machine capable of continuous processing, including a machine base 1. Electromagnetic slide rails 2 and electric cutting heads 10 are respectively mounted on both sides of the top of the machine base 1. A clamping platform 3 is mounted on the top of the electromagnetic slide rails 2, and a support plate 4 is mounted on the top of the clamping platform 3. A disc 5 is fixed to one side of the support plate 4 via four connecting rods. An inner disc 6 is rotatably connected to a recess on the inner side of the disc 5. Clamping bodies 7 are distributed in a circular polarity row on the inner disc 6. The clamping bodies 7 are existing plug-in clamping devices used for pipes.

[0024] It is used to clamp the spindle body 8 and can be released by electric or manual operation. It is cylindrical in shape and will not be described in detail here. A servo motor 9 that drives the inner disc 6 to rotate is installed on one side of the disc 5. A braking assembly 11 is installed on the outside of the disc 5. The braking assembly 11 includes two connecting plates fixed on the outside of the disc 5. A pulley 1101 is rotatably installed on one side of the support plate. A brake belt 1102 is connected between the pulleys 1101. The brake belt 1102 is made of high-strength elastic material. After the inner disc 6 stops rotating each time, one side of the brake belt 1102 is squeezed by a clamp body 7.

[0025] With the above structural design, during processing, several mandrel bodies 8 are first inserted into and fixed inside the fixture body 7 in sequence. At this time, the mandrel bodies 8 are arranged in a ring, and the mandrel body 8 at the bottom corresponds to the processing position of the electric cutting head 10. Then, the electromagnetic slide rail 2 is activated by the control console at the bottom of the machine base 1 to drive the fixture table 3 to move horizontally. The drill bit of the electric cutting head 10 processes this mandrel body 8. After resetting, the servo motor 9 is activated when switching work positions, and the inner disk 6 rotates inside the disk 5, so that the next mandrel body 8 moves to the processing position. During the adjustment process, the mandrel body 8... The clamp body 7 contacts the brake belt 1102 on the pulley 1101 and squeezes the brake belt 1102 during rotation, causing it to deform. The brake belt 1102 is displaced by the rotation of the pulley 1101, which is coordinated with the displacement of the clamp body 7. At the same time, the brake belt 1102 generates a rebound force on the clamp body 7 through its own deformation, which makes it have resistance when rotating, thus achieving a good braking effect. This realizes adjustable multi-station processing, and the simple design of the brake assembly 11 makes the rotation more stable when it stops. In addition, the brake assembly 11 has a simple structure, is easy to replace and maintain, and is worth promoting and using.

[0026] The outer diameter of the inner disk 6 is smaller than the inner diameter of the recess of the disk 5, and the outer wall of the inner disk 6 is provided with a ball groove. The ball groove is equipped with a ball 18, and the ball 18 rolls inside the recess of the disk 5. A sealing gasket 19 is adhered to the outer wall of the inner disk 6 at one side of the ball 18. The sealing gasket 19 is aligned with the outer wall of the disk 5 and the inner disk 6, and the sealing gasket 19 is in contact with the inner wall of the recess of the disk 5.

[0027] In the optimized design of the inner disk 6, the inner disk 6 is rotated and connected by the rolling of the ball 18, so that the inner disk 6 rotates stably in the recess of the disc 5 with very little friction. At the same time, the sealing gasket 19 can enhance the sealing performance, prevent dust from entering the gap, and play a good protective role.

[0028] See Figures 1-3 The top of the machine base 1 is equipped with an electromagnetic slide rail 2 12, and a shock absorber 13 is slidably mounted on the electromagnetic slide rail 2 12. The shock absorber 13 is an existing structural design to prevent excessive vibration when the electric cutting head 10 is operating. The electric cutting head 10 is mounted on the shock absorber 13. The electric cutting head 10 consists of a motor and a drill bit fixed on the shock absorber 13. The drill bit is installed at the output end of the motor, and the type of drill bit is not limited. The electromagnetic slide rail 2 12 and the electromagnetic slide rail 1 2 are perpendicular to each other.

[0029] In terms of machining optimization design, the shock absorber 13 slides on the electromagnetic slide rail 12 to adjust the position of the electric cutting head 10. So, during machining, two shock absorbers 13 (not shown in the figure) can be installed. The type of electric cutting head 10 on the two shock absorbers 13 can be changed according to the requirements, one for drilling and one for cutting. This effectively improves the applicability and eliminates the need to frequently change the electric cutting head 10, which is very convenient. Note that one of them is located at the very edge and does not affect the machining.

[0030] See Figures 2-3 The machine base 1 has a coolant tank 14 placed at the bottom. A liquid pump 15 is installed on each side of the coolant tank 14. The nozzle of the liquid pump 15 is located on both sides of the electric cutting head 10. The machine base 1 has an outlet between the electromagnetic slide rail 2 12 and the electromagnetic slide rail 1 2 at the top. A flared discharge frame 17 is fixed above the outlet. A filter frame 20 connected to the coolant tank 14 is installed below the outlet. A filter plate 21 is installed inside the filter frame 20.

[0031] During drilling or cutting, the pump 15 is started to draw out the coolant from the coolant tank 14 and spray it out through the spray pipe 16 to spray and cool the drilling or cutting position, preventing high temperature damage to the equipment and workpiece. The discharge frame 17 collects the coolant and the debris that falls off during processing, and the filter plate 21 installed inside the filter frame 20 can filter and collect it for reuse, which is very convenient. Note that the drill bit of the electric cutting head 10 is located below the outlet end of the spray pipe 16 to avoid collision during movement.
