Description

Technical Field

[0001] The utility model belongs to the field of cutting tools, and particularly relates to a cutting tool for a carbon fiber chair back. Background Art

[0002] Carbon fiber is a fiber with a diameter of about 5-10 micrometers, mainly composed of carbon atoms, and is usually combined with other materials to form a composite carbon fiber. Carbon fiber has several advantages, including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature resistance, and low thermal expansion. These properties make carbon fiber very popular in the aerospace field.

[0003] The materials of current aircraft seats have gradually been replaced by carbon fiber composites. Carbon fiber aircraft seats have become a trend. Since carbon fiber aircraft seats are hollow, during production, the raw materials are first laid in a closed mold, and then gas is introduced into the mold so that the product becomes hollow after demolding. In order to facilitate the connection of the material to the gas pipeline, the mold deliberately has two tubular air blowing nozzles, and the product will also have two air blowing parts after being formed in the mold. After the product is demolded, it is usually manually taken to a cutting tool for cutting. This method has two defects: First, it is easy to shake when manually holding the product, and it is not easy to accurately calibrate the product and the cutting tool, resulting in unclean cutting or damaging the product; Second, it is easy to cut the worker's hand, causing a safety hazard. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the current method of cutting the air blowing part of a hollow carbon fiber product, which is prone to inaccurate cutting (cutting too much or too little), and is also easy to cut the worker's hand, causing a safety hazard.

[0005] To solve the above technical problem, the utility model provides a cutting tool for a carbon fiber chair back, which includes a bracket and a blank support part, a cutting assembly, a control box, and a clamping assembly arranged on the bracket. The blank support part and the cutting assembly are arranged along the X-axis direction, the control box and the blank support part are arranged along the Y-axis direction. The blank support part is used for placing the chair back blank, and the clamping assembly is used to clamp the chair back blank on the blank support part. Workers can manually operate the control box to control the start and stop of the cutting assembly, and then cut the chair back blank.

[0006] Preferably, the blank support part includes two long rods fixedly arranged on the bracket at intervals. The length extension directions of the two long rods are consistent with the X-axis direction, and the interval between the two long rods is slightly smaller than the width of the chair back blank.

[0007] Preferably, the cutting assembly includes two tools arranged at intervals in the Y-axis direction and a connecting chassis. The bottom of the connecting chassis is fixed on the bracket. The two tools are slidably connected to the top of the connecting chassis. The two tools can move towards each other or away from each other. The minimum distance value between the two tools is equal to the width of the chair back blank, and the maximum distance value is greater than the width value of the chair back blank.

[0008] Preferably, each tool includes a circular hob and a motor. The circular hob is coaxially fixed to the output shaft of the motor, and the axis is consistent with the X-axis direction.

[0009] Preferably, one cylinder is arranged at each end of the connecting chassis along the Y-axis direction. The two cylinders are arranged oppositely. The telescopic rod of one cylinder is fixed to one tool.

[0010] Preferably, it further includes a waste collection box arranged below the bracket. The length direction of the waste collection box is consistent with the Y-axis direction. Both ends of the waste collection box are located between the two tools. The waste collection box is arranged obliquely from one end to the other end.

[0011] Preferably, a protective cover surrounding the circular hob is fixed to the end face of the output shaft of the motor. There are gaps below the opposite sides of the two protective covers, so that a part of the circular hob can be exposed.

[0012] Preferably, the clamping assembly includes two rotary pressing cylinders symmetrically fixed on the bracket, and each rotary pressing cylinder is respectively located outside the two long rods.

[0013] The technical solution of the present utility model has the following beneficial effects:

[0014] The present utility model mainly includes a bracket, a blank support part and a cutting assembly. The blank support part and the cutting assembly are both arranged on the bracket. When cutting, the chair back blank can be placed on the blank support part. After the outer end of the chair back blank is flush with the outer end of the blank support part, the blade of the cutting assembly just corresponds to the intersection of the air blowing part and the chair back, so that the air blowing part can be cut off. When cutting, the present utility model neither needs to hold the chair back blank by hand for cutting, which greatly reduces the safety hazard, nor can ensure the accuracy during cutting.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0021] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] The utility model provides a carbon fiber chair back cutting tool, which includes a bracket 1, a blank support part 2, a cutting assembly 3, a control box 4 and a clamping assembly 7 arranged on the bracket 1. The blank support part 2 and the cutting assembly 3 are arranged along the X-axis direction, and the control box 4 and the blank support part 2 are arranged along the Y-axis direction. The blank support part 2 is used for placing the chair back blank, and the clamping assembly 7 is used for clamping the chair back blank on the blank support part 2. Workers can manually operate the control box 4 to control the start and stop of the cutting assembly 3, and then cut the chair back blank.

[0023] When it is necessary to cut the redundant part on the front side of the chair back blank, first place the chair back blank on the blank support part 2, and make the redundant part of the chair back blank adjacent to the cutting assembly 3. Then the worker manually presses the start button of the cutting assembly 3 on the control box 4, and then the cutting assembly 3 cuts the redundant part of the chair back blank. Finally, the worker manually presses the stop button of the cutting assembly 3 on the control box 4, and the cutting assembly 3 stops working.

[0024] Specifically, the blank support part 2 includes two long rods 21 fixedly arranged on the bracket 1 at intervals. The length extension directions of the two long rods 21 are consistent with the X-axis direction, and the interval between the two long rods 21 is slightly smaller than the width of the chair back blank, so that both sides of the chair back blank can be respectively supported on the two long rods 21.

[0025] Specifically, the cutting assembly 3 includes two cutters 31 arranged at intervals along the Y-axis direction and a connecting chassis 32. The bottom of the connecting chassis 32 is fixed on the bracket 1. The two cutters 31 are slidably connected to the top of the connecting chassis 32. The two cutters 31 can move towards each other or away from each other. The minimum distance value between the two cutters 31 is equal to the width of the chair back blank, and the maximum distance value is greater than the width value of the chair back blank. Each cutter 31 includes a circular hob 311 and a motor 312. The circular hob 311 is coaxially fixed with the output shaft of the motor 312, and the axis is consistent with the X-axis direction. Since the part to be cut has two parts and is respectively located on both side edges of the width of the chair back blank, when cutting is required, the two cutters 31 move towards each other, and each cutter 31 approaches one of the width edges of the chair back blank. At the same time, the rotating shaft of the motor 312 drives the circular hob 311 to rotate, and each circular hob 311 cuts the corresponding redundant part. After cutting is completed, the two cutters 31 move away from each other, away from the width edges of the chair back blank, facilitating the worker to take down the chair back blank.

[0026] In the utility model, a cylinder 33 is respectively arranged at both ends of the connecting chassis 32 along the Y-axis direction. The two cylinders 33 are arranged oppositely, and the telescopic rod ends of the two cylinders 33 are respectively fixed to the motor 312 of the cutter 31, so that the corresponding cutter 31 can be pushed or pulled.

[0027] The utility model further includes a waste collection box 5 disposed below the bracket 1. The length direction of the waste collection box 5 is consistent with the Y-axis direction. Both ends of the waste collection box 5 are located between the two cutting tools 31, and the length covers the moving ranges of the two cutting tools 31. The length of the waste collection box 5 covers the length of the movement of the two cutting tools 31. The waste collection box 5 is inclined from one end to the other end. The waste collection box 5 is inclined from one end to the other end. When the redundant part on the chair back blank is cut off, it will directly fall into the waste collection box 5 and slide to the lower end of the waste collection box 5. On the one hand, this is conducive to the collection of waste, saving the trouble of picking up waste subsequently. On the other hand, it can prevent the cut waste from directly accumulating under the bracket 1 and causing heavy pressure on the bracket 1 or jamming the cutting tool 31. The waste in the lower end of the waste collection box 5 can be cleaned regularly.

[0028] In order to prevent the cutting debris from flying everywhere and affecting the workshop environment during cutting, a protective cover 313 surrounding the circular hob 311 is fixed to the end face of the output shaft where the motor 312 extends. There are notches 313a below the opposite sides of the two protective covers 313, so that a part of the circular hob 311 can be exposed. During cutting, the debris will be intercepted by the protective cover 313, and at the same time, the debris will fall into the waste collection box 5 from the notches 313a.

[0029] The clamping assembly 7 includes two rotary pressing cylinders 71 symmetrically fixed on the bracket 1, and each rotary pressing cylinder 71 is respectively located beside the outer sides of the two long rods 21. After the chair back blank is placed on the blank support portion 2, the pressing block of the rotary pressing cylinder 71 first rotates above the chair back blank, and then the telescopic rod of the rotary pressing cylinder 71 shortens, and the pressing block presses the chair back blank from below to prevent the chair back blank from moving during cutting.

[0030] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the creation of the present utility model.
