Description

Technical Field

[0001] This utility model relates to the field of automotive sheet metal production technology, specifically a marking code box. Background Technology

[0002] With the development of the automotive industry, the demand for stamping automotive sheet metal parts is increasing, and the requirements for the reliability of production lines are becoming more and more stringent. On automated stamping production lines for automotive sheet metal parts, workpieces from different production batches need to be marked with different serial numbers using a marking device. The requirements for different production batches are met by changing the characters in the character box on the marking device.

[0003] Currently, commonly used character code boxes are typically like... Figure 9 As shown, the character codes are filled into the bottom of the character code box in the prescribed order and fixed in place. When the character code content needs to be adjusted, not only does the entire character code box need to be disassembled, but all the old character codes also need to be removed and the new character codes installed. The whole process is quite cumbersome, and the storage of excess character codes is also inconvenient. Utility Model Content

[0004] To address the aforementioned issues, this application provides a character code box for marking, which allows for adjustment of the marking content simply by rotating the character code wheel, eliminating the need to disassemble the entire character code box, making the operation simple and quick.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A marking code box includes a code box body, wherein a first slot is provided on the code box body;

[0007] A rotating character code is coaxially arranged in the first slot. The rotating character code is rotatably connected to the main body of the character code box through a rotating shaft, and each of the rotating character codes can rotate independently.

[0008] The rotary character code is provided with several sets of character code text;

[0009] The main body of the character code box is provided with a fixing pin;

[0010] The rotary character code has a second slot between two adjacent character codes;

[0011] The fixing pin has two working states;

[0012] When the fixing pin is in the first working state, the fixing pin extends into the second slot and restricts the rotation of the rotary code.

[0013] When the fixing pin is in the second working state, the rotating wheel code is not restricted by the fixing pin and can rotate freely.

[0014] Furthermore, the main body of the character code box is provided with first fixing holes on both sides of the first slot, and the two ends of the rotating shaft extend through the first fixing holes to the outside of the main body of the character code box. The rotating shaft is provided with retaining rings on both sides of the main body of the character code box, and the rotating wheel character code is provided with a fourth fixing hole that rotates with the rotating shaft.

[0015] Furthermore, the main body of the character box is provided with a second fixing hole for accommodating the fixing pin, and the distance between the axis of the second fixing hole and the upper side of the first slot is less than the radius of the second fixing hole.

[0016] Furthermore, the fixing pin includes a head and a positioning part, the positioning part is inserted into the second fixing hole, and a positioning protrusion that cooperates with the second groove is formed in the first groove.

[0017] Furthermore, the positioning part is provided with a detachable limiting pin.

[0018] Furthermore, the positioning part has a cylindrical structure, a baffle is provided on the end face of the positioning part, a spring is sleeved on the positioning part between the main body of the character box and the baffle, and an avoidance notch is provided on the positioning part corresponding to the first slot. When the fixing pin is in the first working state, the avoidance notch is facing away from the rotating character box, and when the fixing pin is in the second working state, the avoidance notch is facing towards the rotating character box.

[0019] Furthermore, a positioning post is provided on the stepped surface between the head and the positioning part, and a first positioning hole and a second positioning hole are provided on the main body of the character box. When the positioning post is inserted into the first positioning hole, the fixing pin is in a first working state, and when the positioning post is inserted into the second positioning hole, the fixing pin is in a second working state.

[0020] Furthermore, the second slot corresponds one-to-one with the character code printed on the rotary character code, and the second slot is provided with the character code text corresponding to the corresponding character code printed text. When the required character code printed text is in the working position, the corresponding character code text is located in a position that can be observed.

[0021] Furthermore, the main body of the character code box is provided with indicator marks on one or both sides of the first slot. When the required character code text faces downward, the indicator marks point to the corresponding character code text.

[0022] Furthermore, a fixing member is provided on the side of the character code box body facing away from the first slot, and one end of the fixing member is fixedly connected to the character code box body in a detachable manner.

[0023] The beneficial effects of this utility model are:

[0024] The marking code box provided in this application embodiment is equipped with a rotating wheel code that can rotate around a pivot, and various code texts are set on the outer side of the rotating wheel code. In this way, a single rotating wheel code can meet the marking requirements of multiple characters. When adjusting the code content, there is no need to disassemble the entire code box. The marking content can be adjusted by rotating the rotating wheel code, which is simple and quick to operate.

[0025] By setting a second slot at the edge of the rotary type between adjacent type prints, and engaging with a fixing pin on the type box body, the rotation of the rotary type is restricted. This prevents the rotary type from rotating during marking, thus avoiding errors or unclear markings. Furthermore, the rotary type can be rotated simply by changing the working state of the fixing pin, making operation convenient. This structure ensures both reliability and ease of operation.

[0037] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the protection scope of this application.

[0038] To facilitate understanding of the specific embodiments of this application, a coordinate system is now defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0039] Example 1

[0040] like Figure 1 As shown, a marking code box includes a code box body 11. A first slot 111 is provided on the code box body 11, and multiple rotating code wheels 12 are coaxially arranged within the first slot 111. The multiple rotating code wheels 12 are rotatably connected to the code box body 11 via a rotating shaft 13, and each rotating code wheel 12 can rotate independently. Several sets of code imprints 122 protruding from the cylindrical side of each rotating code wheel 12 are evenly distributed along the circumference. Each set of code imprints 122 may contain a single character or multiple characters, including but not limited to letters, numbers, Chinese characters, or other symbols.

[0041] according to Figure 1 In the coordinate system shown, the first slot 111 is located at the lower end of the character box body 11 and the opening faces downward, and the axis of the rotating character 12 extends in the left-right direction.

[0042] By setting the rotary character code 12, it is not only convenient to adjust the character code content, but also the individual size of the rotary character code 12 is significantly improved compared with the traditional character code, which increases the force-bearing area during marking, optimizes the force situation of the overall device, and enables it to better cope with the pressure impact during continuous production and reduce the probability of damage.

[0043] As one specific implementation method, such as Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the main body 11 of the character code box is provided with first fixing holes 112 on the left and right sides of the first slot 111, and the first fixing holes 112 are through holes. The rotating shaft 13 is located inside the first slot 111, and both ends of the rotating shaft 13 extend through the first fixing holes 112 to the outside of the main body 11 of the character code box. The rotating shaft 13 is provided with retaining rings 16 on the left and right sides of the main body 11 of the character code box to prevent the rotating shaft 13 from slipping off the main body 11 of the character code box. The rotating wheel character code 12 is coaxially arranged with the rotating shaft 13, and the rotating wheel character code 12 is provided with a fourth fixing hole 121 that rotatably engages with the rotating shaft 13.

[0044] like Figure 3 , Figure 4 and Figure 5 As shown, a fixing pin 14 is provided on the main body 11 of the character box, and a second slot 124 is provided at the edge of the rotating character 12 between two adjacent character imprints 122. The fixing pin 14 has two working states. When the fixing pin 14 is in the first working state, the fixing pin 14 extends into the second slot 124 and restricts the rotation of the rotating character 12; when the fixing pin 14 is in the second working state, the rotating character 12 is not restricted by the fixing pin 14 and can rotate freely.

[0045] By setting a fixing pin 14 and a second slot 124 on the rotary character 12 that mates with the fixing pin 14, the rotary character 12 can be prevented from rotating during the marking process, thus avoiding errors or unclear markings. Furthermore, the rotary character 12 can be rotated simply by removing the fixing pin 14, making operation convenient. This structure ensures both reliability and ease of operation.

[0046] As one specific implementation method, such as Figure 2 , Figure 4 , Figure 5As shown, in this embodiment, the main body 11 of the character code box is provided with a second fixing hole 113 penetrating the main body 11 in the left-right direction, and the distance M between the axis of the second fixing hole 113 and the upper side of the first slot 111 is less than the radius of the second fixing hole 113. The fixing pin 14 includes a positioning part 142, one end of which (according to...) Figure 1 In the coordinate system shown, a head 141 is provided at the left end of the positioning part 142. The diameter of the head 141 is larger than the diameter of the positioning part 142, and a stepped surface is formed. The positioning part 142 of the fixing pin 14 is inserted into the second fixing hole 113 from left to right, and a positioning protrusion extending downward from the upper side of the first slot 111 is formed in the first slot 111. The positioning protrusion extends downward into the second slot 124 of the rotating character code 12, thereby restricting the rotation of the rotating character code 12. The right end of the positioning part 142 extends through the second fixing hole 113 to the right side of the character code box body 11. A detachable limiting pin 17 is provided on the positioning part 142 on the right side of the character code box body 11. For example, the limiting pin 17 is a cotter pin. When the limiting pin 17 is removed and the fixing pin 14 is pulled out, the fixing pin 14 is in the second working state. At this time, the rotating character 12 is not restricted by the fixing pin 14 and can rotate freely.

[0047] The cross-sectional shape of the positioning part 142 of the fixing pin 14 can be polygonal, circular, elliptical or any irregular closed-loop shape, and the shape of the second slot 124 matches the cross-sectional shape of the positioning protrusion formed by the positioning part 142.

[0048] In one specific embodiment, the positioning part 142 of the fixing pin 14 has a circular cross-sectional shape, the second slot 124 has an arc-shaped structure, and the distance between the second slot 124 and the fourth fixing hole 121 is the same as the distance between the first fixing hole 112 and the second fixing hole 113.

[0049] The fixing pin 14 can be set at any position around the rotating wheel code 12. In one specific embodiment, the fixing pin 14 is located directly above the rotating shaft 13.

[0050] Furthermore, the sum of the thicknesses of the plurality of rotary code 12 is equal to the width of the first slot 111, thereby restricting the degree of freedom of the rotary code 12 to move axially along the rotating shaft 13.

[0051] Furthermore, the second slot 124 corresponds one-to-one with the character prints 122 on the rotary character code 12, and the second slot 124 is provided with character text 123 corresponding to the corresponding character prints 122. That is, the character text 123 is the same as the mark printed by the corresponding character prints 122. During operation, the rotary character code 12 is rotated so that the required character prints 122 face downwards. At this time, on the one hand, the corresponding character text 123 faces forward, and the currently used character prints 122 can be determined by the character text 123. On the other hand, all the second slots 124 of the rotary character codes 12 with corresponding character text 123 are aligned and coaxial with the second fixing hole 113. At this time, the fixing pin 14 is passed through the second fixing hole 113 and the second slot 124, and the fixing pin 14 is fixed to the character code box body 11, and the rotary character code 12 is completely fixed.

[0052] By providing the character code text 123 corresponding to the required character code imprint 122 in the second groove 124 on the outer edge of the rotary character code 12, the selected character code content can be intuitively confirmed without disassembly or identification, making it convenient to check whether the character code content is correct.

[0053] As one specific implementation method, such as Figure 4 As shown, in this embodiment, when the required character code text 122 is in the working position (i.e., facing downwards), the character code text 122 and the corresponding character code text 123 face forward. For example, the angle α between the character code text 122 and the corresponding character code text 123 ranges from 60° to 120°.

[0054] Furthermore, such as Figure 1 As shown, an indicator mark is provided on one or both sides of the front side of the character code box body 11, located at the first slot 111. When the required character code text 122 faces downward, the indicator mark points to the corresponding character code text 123. In one specific embodiment, an indicator mark is provided on the right side of the front side of the character code box body 11, located at the first slot 111.

[0055] Furthermore, a third fixing hole 114 is provided on the top of the character code box body 11, and a fixing member 15 is provided in the third fixing hole 114. The lower end of the fixing member 15 is inserted into the third fixing hole 114 and is fixedly connected to the character code box body 11 in a detachable manner. Figure 6 As shown, the pressure head 21 of the marking device 2 is provided with a mounting hole, and the cross-sectional shape of the upper end of the fixing member 15 matches the mounting hole. Through the fixing member 15, the marking character box 1 is installed on the marking device 2, and the overall assembly and disassembly of the marking character box 1 is completed.

[0056] In one specific embodiment, the lower end of the fastener 15 is fixedly connected to the character box body 11 by an interference fit.

[0057] Furthermore, the fixing member 15 is provided with an annular boss 151, the portion located below the annular boss 151 is the lower end of the fixing member 15, and the portion located above the annular boss 151 is the upper end of the fixing member 15. Flat openings 1511 are symmetrically arranged on the annular boss 151.

[0058] The fastener 15 adopts a detachable fixing method and can be customized according to the requirements of the marking device 2. By replacing the fastener 15, a single set of equipment can be used for multiple marking devices 2, making it widely applicable.

[0059] Example 2

[0060] Remove the retaining ring 16. Set screws are respectively provided on the left and right sides of the first slot 111 on the main body 11 of the character code box, and the ends of the set screws are pressed against the rotating shaft 13. The rotating shaft 13 is fixedly connected to the main body 11 of the character code box under the tightening action of the set screws.

[0061] The rest of the structure is the same as in Example 1.

[0062] Example 3

[0063] Remove the retaining ring 16. The length of the rotating shaft 13 is equal to the width of the first slot 111. Locking screws, coaxially arranged with the rotating shaft 13, are respectively provided on the left and right sides of the character box body 11. The character box body 11 has clearance holes for accommodating the locking screws. The end face of the rotating shaft 13 has a threaded hole that mates with the locking screw. The end of the locking screw passes through the clearance hole and is connected and fixed to the rotating shaft 13 via a threaded connection.

[0064] The rest of the structure is the same as in Example 1.

[0065] Example 4

[0066] Remove the limiting pin 17. The outer surface of the head 141 of the fixing pin 14 is provided with external threads. The second fixing hole 113 is a stepped hole, comprising a first hole section and a second hole section from left to right. The diameter of the first hole section is larger than the diameter of the second hole section, and the diameter of the second hole section is equal to the positioning part 142 of the fixing pin 14. The first hole section is provided with internal threads that mate with the external threads of the head 141 of the fixing pin 14. The end face of the head 141 of the fixing pin 14 is provided with a insertion hole for mates with a tool wrench.

[0067] The rest of the structure is the same as in Example 1.

[0068] Example 5

[0069] Remove the limiting pin 17. The fixing pin 14 is an optical axis, and set screws for tightening the fixing pin 14 are respectively provided on the left and right sides of the character box body 11 located at the first slot 111. The rest of the structure is the same as in Embodiment 1.

[0070] Example 6

[0071] With the limiting pin 17 removed, the positioning part 142 of the fixing pin 14 has a cylindrical structure.

[0072] like Figure 7 and Figure 8 As shown, a baffle 18 is provided on the right end face of the positioning part 142, and a spring 19 is sleeved on the positioning part 142 between the character box body 11 and the baffle 18, and the head 141 is pressed against the left side face of the character box body 11 under the elastic action of the spring 19.

[0073] The positioning portion 142 of the fixing pin 14 is provided with a clearance notch 1421. The axial dimension of the clearance notch 1421 is equal to the width of the first slot 111, that is, the left side of the clearance notch 1421 is flush with the left side of the first slot 111, and the right side of the clearance notch 1421 is flush with the right side of the first slot 111. When the fixing pin 14 is in the first working state, the clearance notch 1421 is facing away from the rotating code 12. At this time, the part of the positioning portion 142 located at the clearance notch 1421 forms a positioning protrusion and extends into the second slot 124 of the rotating code 12, thereby restricting the rotation of the rotating code 12. When the fixing pin 14 is in the second working state, the clearance notch 1421 is facing the rotating code 12, thereby avoiding the rotating code 12, and the rotating code 12 can rotate freely.

[0074] In one specific implementation, when the fixing pin 14 is in the second working state, the bottom surface of the clearance notch 1421 is parallel to the upper side surface of the first slot 111, forming a complete plane.

[0075] Furthermore, a positioning post 1411 is provided on the stepped surface of the fixing pin 14, and a first positioning hole 115 and a second positioning hole 116 are provided on the left side of the character box body 11. When the positioning post 1411 is inserted into the first positioning hole 115, the fixing pin 14 is in a first working state; when the positioning post 1411 is inserted into the second positioning hole 116, the fixing pin 14 is in a second working state.
