Description

Technical Field

[0001] The present application relates to the technical field of surface treatment for column bending forming, and specifically discloses a surface treatment device for column bending forming. Background Art

[0002] As shown in the Figure 1 description appendix Figure 1 The description appendix shows the company's existing column products. This column product is formed by splicing two half-frame columns. There is an installation channel in the middle of the two half-frame columns. The installation channel is a straight channel, which is used to sleeve a precision catheter. This is equivalent to the product shown in the Figure 1 description appendix being a catheter protection column. Because the outer shell of this precision catheter is relatively thin, it generally needs to be used in conjunction with the product shown in the Figure 1 description appendix; The two half-frame columns are usually formed by stamping with a stamping die. After stamping, surface treatment needs to be carried out on the installation channel. At this time, the installation channel is a curved surface and needs to be in contact with the outer shell of the precision catheter. Therefore, strict control of the surface smoothness of this curved surface is required, and the two ends of the installation channel also need to be designed with a curved surface. Because the precision catheter is very fragile, if the curved surface is not used, the outer shell of the precision catheter is very easy to break; At present: The two common operating methods are: Manually polish the inner curved surface of the installation channel and the end curved surface of the installation channel. After polishing, then splice the two half-frame columns; Design a special fixture and use a numerical control machine tool to machine-polish the inner curved surface of the installation channel and the end curved surface of the installation channel; The current problems are: For the first method: The surface smoothness cannot be well controlled. The polishing of the inner curved surface of the installation channel and the end curved surface of the installation channel is a pain point problem. Because once too much polishing is done and there is too large a gap between the precision catheter and this position, it is very easy to cause damage to the precision catheter. Since the two half-frame columns are spliced, manual polishing cannot ensure the same surface smoothness of the inner curved surface of the installation channel and the end curved surface of the installation channel of the two half-frame columns; For the second method: The machine cost and polishing efficiency are unacceptable. In view of this, the present invention provides a surface treatment device for column bending forming to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem that the polishing of the traditional column with a channel inside and the end curved surface formed at the end of the column is not accurate enough.

[0004] To achieve the above purpose, the present invention provides the following basic solution: A surface treatment device for bending and forming a column, comprising a fixing component for vertically fixing the column and a grinding component placed on the upper end surface of the column and capable of penetrating into the column to grind the inner curved surface and the end curved surface of the column. The column needs to be placed on the fixing component twice with different end surfaces and is acted on by the fixing component; The grinding component includes a thin tube, an upper end plate arranged at the upper end of the thin tube in sequence from top to bottom, a trigger at the lower end of the thin tube, an inclined expansion part arranged near the upper end of the thin tube, and an expansion fixing component arranged near the lower end of the thin tube; Both the expansion fixing component and the inclined expansion part expand in diameter after being filled with gas. The inclined expansion part expands and expands in diameter obliquely, and the expansion fixing component expands and expands in diameter horizontally. The expansion fixing component and the inclined expansion part are respectively used for grinding the inner curved surface and the end curved surface of the column.

[0005] Further, the fixing component includes a fixing plate, a receiving groove opened on the fixing plate, and several iron blocks. The column is placed perpendicular to the receiving groove. The receiving groove is made of a magnetic material. After the column is placed perpendicular to the receiving groove, the iron blocks are magnetically connected to the receiving groove and fixed around the column.

[0006] Further, the upper end plate contacts the upper end surface of the vertically placed column, and several anti-slip grooves are circumferentially arranged on the thin tube above the upper end plate.

[0007] Further, the trigger is a pressure sensor. The pressure sensor is an indicator for the inclined expansion part and the expansion fixing component. When the pressure sensor receives a pressure instruction, the expansion fixing component is activated.

[0008] Further, the expansion fixing component includes an upper cover, a lower cover, a connecting cylinder arranged between the upper cover and the lower cover, a connecting collar arranged inside the connecting cylinder and in contact with the thin tube, and an expansion part for grinding the inner curved surface of the column is installed on the connecting cylinder between the upper cover and the lower cover.

[0009] Further, the expansion part includes sliding grooves opened on the upper cover and the lower cover, connecting columns slidably connected to the sliding grooves, grinding plates arranged at the free ends of the connecting columns, and an expansion body arranged between the upper cover and the lower cover.

[0010] Further, the expansion body includes an inner fixing layer, an outer expansion layer, and several springs arranged between the inner fixing layer and the outer expansion layer. The inner fixing layer and the outer expansion layer form an expansion area inside. Several air vents communicating with the expansion area are opened on the upper cover. The air vents are connected with an air pipe, and the free end of the air pipe is connected with a conduit and a gas generator.

[0011] Further, the inclined expansion part includes a reference plate, a laser emitter arranged on the reference plate, a connection hole opened at the center of the reference plate for connecting a thin tube, inclined plates rotatably connected to both sides of the reference plate, and expansion rings arranged at the ends of the inclined plates. The expansion rings, inclined plates, and reference plate form a sealing ring. The inside of the sealing ring is an inclined area, and the inclined area is connected to the conduit and the gas generator.

[0012] Further, rubber sealing rings are provided at the connection between the sealing ring and the thin tube and at the connection between the reference plate and the inclined plate.

[0013] The principle and effect of this solution are as follows: 1. Compared with the prior art, the structure of this device is simple and ingenious. This device is a dedicated surface treatment device with a channel inside the column. It can polish the inner wall and the end curved surface of the channel of the column after splicing, and there is no need to polish before splicing. Compared with polishing before splicing, the efficiency is higher and the quality can be better guaranteed.

[0014] 2. Compared with the prior art, this device has a rotary polishing function and an up-and-down polishing function. The polishing function is complete and comprehensive, and it can quickly process the barbs and uneven surfaces on the inner curved surface channel and the end curved surface of the curved surface channel of the column.

[0015] 3. Compared with the prior art, since this device polishes after splicing the columns, for polishing, the quality of the two semi-frame columns can be controlled to be highly consistent.

The inclined expansion part can reasonably adjust according to the inclination degree of the end curved surface, so that the inclined expansion part acts reasonably on the end curved surface to polish the end curved surface. The action of polishing the end curved surface and the action of fully polishing the inner curved surface channel of the column are completed by the same device. In terms of time, it takes less time. Although this device uses manual operation, the polishing degree and the quality of the polished product can still be ensured after manual operation. In terms of product quality, after using this device, the product quality can be highly guaranteed. Description of the Drawings

Detailed Embodiments

[0020] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, will detail the specific embodiments, structures, features, and their effects of the present invention as follows.

[0021] The reference numerals in the accompanying drawings of the specification include: column 1, inner curved surface 2, end curved surface 3, fixing plate 4, iron block 5, receiving groove 6, thin tube 7, trigger 8, anti-slip groove 9, upper end plate 10, conduit 11, ventilation pipe 12, upper cover 13, expansion body 14, outer expansion layer 1401, spring 1402, inner fixing layer 1403, connecting column 15, grinding plate 16, lower cover 17, connecting cylinder 18, connecting sleeve 19, sliding groove 20, inclined expansion part 21, expansion ring 2101, inclined area 2102, inclined plate 2103, rotating shaft 2104, reference plate 2105.

[0022] Embodiment is as Figures 1 - 7 shown: A surface treatment device for bending and forming a column, comprising a fixing component for vertically fixing the column 1 and a grinding component placed on the upper end surface of the column 1 and capable of penetrating into the column 1 to grind the inner curved surface 2 and the end curved surface 3 of the column 1. The column 1 needs to be placed on the fixing component twice with different end faces and be acted on by the fixing component; The grinding component includes a thin tube 7, an upper end plate 10 arranged at the upper end of the thin tube 7 in sequence from top to bottom, a trigger 8 at the lower end of the thin tube 7, an inclined expansion part 21 arranged near the upper end of the thin tube 7, and an expansion fixing component arranged near the lower end of the thin tube 7. The upper end plate 10 contacts the upper end surface of the vertically placed column 1. A plurality of anti-slip grooves 9 are circumferentially arranged on the thin tube 7 above the upper end plate 10. The anti-slip grooves 9 are used because the grinding component needs to be rotated manually, and the anti-slip grooves 9 can increase the friction during contact.

[0023] Both the expansion fixing component and the inclined expansion part 21 are expanded by gas injection to increase the diameter. The inclined expansion part 21 expands and increases the diameter in an inclined manner, and the expansion fixing component expands and increases the diameter horizontally. The expansion fixing component and the inclined expansion part 21 are respectively used to grind the inner curved surface 2 and the end curved surface 3 of the column 1.

[0024] Regarding the fixing component: The fixing component includes a fixing plate 4, a receiving groove 6 opened on the fixing plate 4, and a plurality of iron blocks 5. The column 1 is placed perpendicular to the receiving groove 6. The receiving groove 6 is made of magnetic material. After the column 1 is placed perpendicular to the receiving groove 6, the iron blocks 5 are magnetically connected to the receiving groove 6 and fixed around the column 1.

[0025] Specifically: The column 1 is vertically placed in the receiving groove 6, and then the iron blocks 5 are magnetically fixed to the receiving groove 6 and fixed around the column 1 by using the iron blocks 5, thereby realizing the fixation of the column 1; The trigger 8 is a pressure sensor. The pressure sensor is an indicator for the inclined expansion part 21 and the expansion fixing component. When the pressure sensor receives a pressure command, the expansion fixing component is activated.

[0026] Since the grinding component needs to be inserted into the column 1, the bottom of the thin tube 7 will contact the receiving groove 6 at this time. When the bottom of the thin tube 7 contacts the receiving groove 6, it indicates that the grinding component has been placed in place, and the expansion fixing component can start to be activated; The expansion fixing component includes an upper cover 13, a lower cover 17, a connecting cylinder 18 arranged between the upper cover 13 and the lower cover 17, a connecting collar 19 arranged inside the connecting cylinder 18 and in contact with the thin tube 7, and an expansion part for grinding the inner curved surface 2 of the column 1 is installed on the connecting cylinder 18 between the upper cover 13 and the lower cover 17.

[0027] When the thin tube 7 rotates, the expansion and fixation assembly will also rotate accordingly. The expansion part includes sliding grooves 20 formed on the upper cover 13 and the lower cover 17, connecting columns 15 slidably connected to the sliding grooves 20, polishing plates 16 provided at the free ends of the connecting columns 15, and an expansion body 14 provided between the upper cover 13 and the lower cover 17.

[0028] The expansion body 14 includes an inner fixing layer 1403, an outer expansion layer 1401, and a plurality of springs 1402 provided between the inner fixing layer 1403 and the outer expansion layer 1401. The inner fixing layer 1403 and the outer expansion layer 1401 internally form an expansion area. A plurality of ventilation holes communicating with the expansion area are formed on the upper cover 13. The ventilation holes are connected with a ventilation pipe 12. The free end of the ventilation pipe 12 is connected with a catheter 11 and a gas generator.

[0029] Since the expansion and fixation assembly starts to operate, the gas generator receives a start signal, generates gas and enters the catheter 11, then enters the ventilation pipe 12, and enters the expansion area along the ventilation holes, causing the outer expansion layer 1401 to expand. At this time, the springs 1402 are stretched. Due to the expansion of the outer expansion layer 1401, the outer expansion layer 1401 pushes the connecting column 15 to slide on the sliding groove 20 and slide outwards, thereby changing the diameter expansion of the polishing plate 16. At this time, the polishing plate 16 generates pressure on the inner curved surface 2, and rotational polishing and up-and-down polishing are realized under the action of the pressure. Since the pressure is increased by gas, the polishing pressure can be controlled by the amount of gas input by the gas generator, thereby realizing precise control; In the present device, both the rotational polishing and the up-and-down polishing are achieved by manually rotating the thin tube 7 and moving the thin tube 7 up and down; Since the bottom of the column 1 is restricted by the fixing assembly, the inner curved surface 2 and the end curved surface 3 at the bottom of the column 1 cannot be acted on by the polishing assembly. Therefore, during the actual operation of the present device, the column 1 needs to be placed on the fixing assembly twice with different end faces to be acted on by the fixing assembly.

[0030] Regarding the inclined expansion part 2,1 in the present application: The inclined expansion part 21 includes a reference plate 2105, a laser emitter provided on the reference plate 2105, a connection hole opened at the center of the reference plate 2105 for connecting the thin tube 7, inclined plates 2103 rotatably connected to both sides of the reference plate 2105, and expansion rings 2101 provided at the ends of the inclined plates 2103. The expansion rings 2101, the inclined plates 2103, and the reference plate 2105 form a sealing ring. The inside of the sealing ring is an inclined area 2102. The inclined area 2102 is connected to the catheter 11 and the gas generator. Rubber sealing rings are provided at the connection between the sealing ring and the thin tube 7 and at the connection between the reference plate 2105 and the inclined plates 2103. Both ends of the reference plate 2105 are rotating shafts 2104, and the inclined plates 2103 are rotatably connected to the rotating shafts 2104; Specifically: when the thin tube 7 moves upward manually, the reference plate 2105 moves toward the end surface 3, enabling the laser emitted by the laser emitter to be emitted outward to the end surface 3, indicating that the reference plate 2105 is flush with the lower reference of the end surface 3 at this time. Then, the gas generator is used to inflate the inclined area 2102 again, and the expansion ring 2101 expands, driving the inclined plate 2103 to tilt outward, so that the inclined plate 2103 tilts and contacts the end surface 3. When the inclined plate 2103 tilts and contacts the end surface 3, the position between the inclined expansion part 21 and the end surface 3 is fixed. By rotating the thin tube 7, the inclined plate 2103 acts on the end surface 3 to polish the end surface 3.

[0031] This device solves the problem that the polishing of the end surface 3 formed by the channel in the traditional column 1 with a channel inside is not accurate enough.

[0032] The above is only a preferred embodiment of the present invention, and it does not impose any formal restrictions on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the above-disclosed technical content without departing from the technical solution of the present invention. However, as long as it does not depart from the technical solution content of the present invention, any brief modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
