Technical Field

[0001] This utility model relates to the field of automotive lens processing technology, and in particular to a precision cutting device for anti-chipping lens slitting. Background Technology

[0002] The lighting systems commonly used in automotive headlights generally include a light source, a reflector, a light shield, and a lens. When manufacturing a lens, a certain length of wire rod material is usually cut into block raw materials. The block raw materials are then molded at high temperature and cooled to obtain the required lens for automotive headlights.

[0003] Currently, when cutting the rod material for processing lenses, it is usually necessary to position the rod material first. However, when positioning the rod material, only one side of the position to be cut is clamped. During the cutting process, the rod material has poor stability and is prone to shaking. Moreover, the cutting position is directly exposed, and edge material is prone to break out during the cutting process, causing injury to workers. Utility Model Content

[0004] This utility model provides a precision cutting device for anti-chipping lens slitting, which makes the bar stock more stable during cutting and less prone to shaking. In addition, the cutting baffle can block the chipped edge material during cutting, preventing injury to workers.

[0005] In a first aspect, this utility model provides a precision cutting device for anti-chipping lenses, specifically comprising: a base; a side support plate fixed to the top left side of the base; a support block fixed to the middle right side of the side support plate; three guide brackets fixed in a ring arrangement on the outer side of the support block, each guide bracket having a bar clamping plate slidably mounted on it, each bar clamping plate having a bar clamping rod fixed to its right end, and each guide bracket also having a lead screw rotatably mounted on it; a rotating shaft rotatably mounted inside the support block; a stepper motor mounted on the left side of the side support plate, with the right end of the stepper motor's spindle fixedly connected to the left end of the rotating shaft; a cutting baffle fixed to the top of the base; and a pallet support block fixed to the top right side of the base, with a bar pallet slidably mounted on the top of the pallet support block.

[0006] The cutting baffle is a U-shaped plate that covers the front and rear sides of the protrusions on the three bar clamping rods. A tempered glass window is also provided on the front side of the cutting baffle.

[0007] Each of the bar clamps is provided with a threaded hole corresponding to the lead screw, and the distance between the three bar clamps and the center line of the support block is equal.

[0008] The left end of the bar stock support plate is fixedly connected to the right end of the bar stock clamping rod located at the bottom by a cylindrical rod, and the top surface of the bar stock support plate and the top surface of the protrusion on the bar stock clamping rod are located on the same plane.

[0009] The rotating shaft has a bevel gear on its outer side, and each of the lead screws also has a bevel gear on one end. The bevel gear on the outer side of the rotating shaft meshes with the bevel gears on one end of the three lead screws.

[0010] The bar stock support plate has four cylindrical rods symmetrically arranged at the bottom, and these four cylindrical rods can slide up and down in the cylindrical holes at the top of the support plate. The protrusions on the bar stock clamping rods are all wrapped with a layer of rubber.

[0011] Each of the bar clamping rods is provided with two protrusions, and the protrusions on the three bar clamping rods are all in the same position, with the plane on one side of each protrusion facing the center line of the support block.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1: Please refer to Figures 1 to 6 : This utility model proposes a precision cutting device for edge-break prevention lens slitting, comprising: a base 1; a side support plate 2 is fixed to the top left of the base 1, the base 1 is used to support the upper part of the device structure, and the side support plate 2 is used to support the support block 3 and the stepper motor 8; a support block 3 is fixed to the middle of the right side of the side support plate 2, the support block 3 is used to support the guide bracket 4, the lead screw 6 and the rotating shaft 7; three guide brackets 4 are fixed in a ring on the outside of the support block 3, each guide bracket 4 has a bar clamping plate 5 slidably mounted on it, and a bar clamping rod 9 is fixed to the right end of each bar clamping plate 5. A lead screw 6 is also rotatably mounted on each guide bracket 4. When the lead screw 6 rotates, it will cooperate with the threaded hole on the bar clamping plate 5 to drive the bar clamping plate 5 to slide under the support of the guide brackets 4, thereby enabling the bar clamping rod 9 to clamp or release the bar; a rotating shaft 7 is also rotatably mounted inside the support block 3. During rotation, the bevel gear on its outer side and the bevel gear at one end of the lead screw 6 will drive the three lead screws 6 to rotate synchronously. A stepper motor 8 is installed on the left side of the side support plate 2, and the right end of the main shaft of the stepper motor 8 is fixedly connected to the left end of the rotating shaft 7. The stepper motor 8 is used to drive the rotating shaft 7 to rotate. A cutting baffle 10 is also fixed on the top of the base 1. During the cutting process, the cutting baffle 10 can block the edge material that is broken off during cutting to avoid injury to the operator. A pallet support block 11 is fixed on the top right side of the base 1. A bar stock pallet 12 is slidably installed on the top of the pallet support block 11. The pallet support block 11 is used to slide and support the bar stock pallet 12. When the bar stock clamping rod 9 at the bottom moves up and down, it will also drive the bar stock pallet 12 to move up and down synchronously under the support of the pallet support block 11 through the cylindrical rod at its right end. This allows the bar stock pallet 12 to provide auxiliary support for the right side of the bar stock.

[0018] In this embodiment, as Figures 1-3 As shown, the cutting baffle 10 is a U-shaped plate, and it covers the front and rear sides of the protrusions on the three bar clamping rods 9. The cutting baffle 10 is also equipped with a tempered glass window on the front side. During the cutting process, the cutting baffle 10 can cover the edge material that is broken off during cutting to avoid injury to the operator. Moreover, the tempered glass window on the cutting baffle 10 is also convenient for observing the cutting situation.

[0019] In this embodiment, as Figures 1-5 As shown, each bar clamping plate 5 has a threaded hole corresponding to the lead screw 6. The distance between the three bar clamping plates 5 and the center line of the support block 3 is equal. When the lead screw 6 rotates, it will cooperate with the threaded hole on the bar clamping plate 5 to drive the bar clamping plate 5 to slide under the support of the guide bracket 4, so that the bar clamping rod 9 can clamp or release the bar.

[0020] In this embodiment, as Figure 2As shown, the left end of the bar stock support plate 12 is fixedly connected to the right end of the bar stock clamping rod 9 located at the bottom through a cylindrical rod. The top surface of the bar stock support plate 12 and the top surface of the protrusion on the bar stock clamping rod 9 are on the same plane. When the bar stock clamping rod 9 located at the bottom moves up and down, it will also drive the bar stock support plate 12 to move up and down synchronously under the support of the support plate support block 11 through the cylindrical rod at its right end. This allows the bar stock support plate 12 to provide auxiliary support for the right side of the bar stock.

[0021] In this embodiment, as Figure 5 As shown, a bevel gear is provided on the outer side of the rotating shaft 7, and a bevel gear is also provided on one end of each of the lead screws 6. The bevel gear on the outer side of the rotating shaft 7 meshes with the bevel gears at one end of the three lead screws 6. When the rotating shaft 7 rotates, it will drive the three lead screws 6 to rotate synchronously through the bevel gear on its outer side and the bevel gear at one end of the lead screw 6. Therefore, the lead screw 6 can engage with the threaded hole on the bar clamp 5 to drive the bar clamp 5 to move under the support of the guide bracket 4.

[0022] In this embodiment, as Figures 3-5 As shown, each bar clamping rod 9 is provided with two protrusions, and the positions of the protrusions on the three bar clamping rods 9 are all the same. The plane on one side of the protrusion is also facing the center line of the support block 3. When the bar clamping rod 9 moves towards the middle position, it can clamp and fix the bar by relying on the protrusions provided on it, and it can clamp and fix bars of different diameters.

[0023] Example 2, based on Example 1, such as Figures 1-6 As shown, four cylindrical rods are symmetrically arranged at the bottom of the bar stock support plate 12, and these four cylindrical rods can slide up and down in the cylindrical holes at the top of the support plate block 11. The outer side of the protrusions on the bar stock clamping rod 9 is covered with a layer of rubber. When the bar stock clamping rod 9 at the bottom moves up and down, it will also drive the bar stock support plate 12 to move up and down synchronously under the support of the support plate block 11 through the cylindrical rod at its right end. At this time, the cylindrical rod at the bottom of the bar stock support plate 12 and the support plate block 11 cooperate to ensure the stability of the bar stock support plate 12 sliding up and down, while the rubber on the outer side of the protrusions on the bar stock clamping rod 9 can improve the firmness after clamping the bar stock.

[0024] The working principle of this embodiment is as follows: During installation, the device can be fixed on the processing table by the base 1. The stepper motor 8 on the left side of the side support plate 2 is connected to the external controller and power supply. When it is necessary to precisely cut the bar stock for processing lenses, first place the left end of the bar stock to be cut between the three bar stock clamping rods 9, and make the left end of the bar stock roughly aligned with the left end of the left protrusion on the bar stock clamping rod 9. Then, the stepper motor 8 can be controlled by the external controller to drive the rotating shaft 7 to rotate in the forward direction. When the rotating shaft 7 rotates in the forward direction, it will drive the three lead screws 6 to rotate synchronously in the forward direction through the bevel gear on its outer side and the bevel gear at one end of the lead screw 6. Therefore, the lead screw 6 can cooperate with the threaded hole on the bar stock clamping plate 5 to drive the bar stock clamping plate 5 to slide towards the support block 3 under the support of the guide bracket 4. Therefore, the protrusion on the three bar stock clamping rods 9 can firmly hold the bar stock. The bar clamping rod 9 at the bottom is firmly clamped, and when it moves up and down, it also drives the bar support plate 12 to move up and down synchronously under the support of the support block 11 via the cylindrical rod at its right end. This allows the bar support plate 12 to provide auxiliary support for the right side of the bar. Then, the cutting blade can be operated to cut the bar through the opening at the top of the cutting baffle 10. During the cutting process, the cutting baffle 10 can block the edge material that is broken off during cutting, avoiding injury to the operator. Moreover, the tempered glass window on the cutting baffle 10 makes it easy to observe the cutting situation. After the cutting is completed, simply control the stepper motor 8 to drive the rotating shaft 7 to rotate in the opposite direction. At this time, the lead screw 6 will also rotate in the opposite direction, so that the three bar clamping plates 5 can move outward synchronously, thereby releasing the bar clamping rod 9. Then, the cut raw material can be removed and further cutting can be performed.

[0025] The following points should be noted in this article: 1. The accompanying drawings of this embodiment only involve the structures involved in this embodiment; other structures can refer to the general design.

[0026] 2. Where there is no conflict, this embodiment and the features in the embodiment can be combined with each other to obtain new embodiments.
