Description
Technical Field
[0001] The utility model relates to the technical field of laser line casting products, in particular to a magnetic error-proofing tooling for laser line casting products. Background Art
[0002] Laser line tools are used for measuring and marking. They emit a horizontal or vertical laser line, enabling users to make precise horizontal and vertical markings. These tools are widely used in construction, renovation, furniture making, and other fields. Laser line tools typically have a stop magnet, which provides damping to quickly stop the tool's internal oscillating movement, thereby stabilizing the laser line and enabling users to perform measurements and markings.
[0003] like Figure 1 As shown, a common shutdown assembly 10' includes a metal plate 11', a positioning inner ring 12' and a shutdown magnet 13'. A plurality of arc-shaped grooves 120' for accommodating the shutdown magnets 13' are formed on the outer circumference of the positioning inner ring 12'. Typically, the shutdown magnets 13' are six cylindrical magnets, with the N poles and S poles of the magnets arranged in an alternating circular plane on the metal plate 11'. However, during the manufacturing process, since the N poles and S poles of the magnets look the same, the order of magnet arrangement is very easy to confuse, resulting in functional failure or weakening, affecting the function of the machine and customer experience. Summary of the Invention
[0004] In order to solve the deficiencies in the prior art, the utility model proposes a magnetic error-proofing tooling for laser line casting products, which greatly reduces the error rate of the stop assembly when assembling the stop magnet, thereby ensuring the functional quality of the product.
[0005] To achieve the above-mentioned purpose, the utility model provides a magnetic error-proofing tool for laser line projection products, including: a base plate, a guide post, a reset spring, a sliding block and an error-proofing magnet. The guide post is installed on the base plate, the sliding block is installed on the guide post, the reset spring is sleeved on the guide post, and is located between the sliding block and the base plate, so that the sliding block can overcome the spring force of the reset spring and move up and down relative to the guide post. The error-proofing magnet is fixedly set on the top of the sliding block and is arranged in a ring with alternating N poles and S poles.
[0006] In one embodiment, a laser projection product includes a stop assembly, which includes a metal plate and a positioning inner ring. A plurality of arc-shaped grooves for placing stop magnets are formed on the outer circumference of the positioning inner ring. The number of anti-error magnets and the arc-shaped grooves are the same and the positions correspond one to one.
[0007] In one embodiment, when the metal plate is placed on the upper surface of the sliding block, the metal plate and the guide pillars have overlapping areas.
[0008] In one embodiment, the guide post has a limiting step, and the sliding block has a step hole that cooperates with the guide post. The limiting step cooperates with the step hole to prevent the sliding block from separating from the guide post.
[0009] In one embodiment, a first limiting member is provided on the upper surface of the sliding block, and the first limiting member cooperates with the metal plate to limit the position of the metal plate.
[0010] In one embodiment, a second limiting member is provided on the upper surface of the sliding block, and the second limiting member cooperates with the positioning inner ring to limit the position of the positioning inner ring.
[0011] Beneficial effects:
[0012] This utility model provides a specialized tool for assembling the stop assembly of laser line casting products. Utilizing anti-error magnets with alternating north and south poles, this tool addresses the prior art issue of magnetic pole confusion during assembly, which can lead to functional failure. This ensures the functional quality of laser line casting products while also improving production efficiency. Furthermore, the magnetic anti-error tool utilizes anti-error magnets to attract the metal plate of the stop assembly and utilizes the relative motion of a guide post and a sliding block to remove the assembled stop assembly. This simple and convenient operation further enhances assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solution of the present invention will be more clearly and completely explained below by describing the preferred embodiments of the present invention in conjunction with the accompanying drawings.
[0023] The utility model proposes a magnetic error-proofing tooling for laser line-casting products, comprising: a base plate, a guide post, a reset spring, a sliding block and an error-proofing magnet. The guide post is mounted on the base plate, the sliding block is mounted on the guide post, the reset spring is sleeved on the guide post and is located between the sliding block and the base plate, so that the sliding block can overcome the spring force of the reset spring and move up and down relative to the guide post. The error-proofing magnet is fixedly arranged on the top of the sliding block and is arranged in a ring with alternating N poles and S poles.
[0024] The magnetic error-proofing tooling of the utility model provides a professional assembly tooling for the assembly process of the stop components of laser projection products. In addition, the tooling can solve the problem of easy installation errors of the stop magnets in the existing technology, thereby reducing the error rate and improving the production efficiency of the product.
[0025] like Figure 2 and Figure 3 As shown, the preferred embodiment of the present invention, a magnetic error-proofing fixture 10 for laser line casting products, includes a base plate 1, a guide post 2, a return spring 3, a sliding block 4, and an error-proofing magnet 5. The guide post 2 is mounted on the base plate 1. Specifically, the lower end of the guide post 2 is mounted to the base plate 1 via a threaded connection.
[0026] The sliding block 4 is mounted on the guide post 2 , and the return spring 3 is sleeved on the guide post 2 and located between the sliding block 4 and the base plate 1 , so that the sliding block 4 can overcome the spring force of the return spring 3 and move downward relative to the guide post 2 .
[0027] Specifically, in this preferred embodiment, there are two guide posts 2, and the sliding block 4 is mounted on the guide posts 2 via a hole-fitting arrangement. The sliding block 4 comprises an upper portion 41 and a lower portion 42. The lower portion 42 is shaped similarly to the base plate 1, and the upper portion 41 is smaller in volume than the lower portion 42 and is connected to the center of the lower portion 42. The hole 40 in the sliding block 4, which mates with the guide post 2, extends from the lower portion 42 to the upper portion 41, passing through the entire sliding block 4. The hole 40 is located on either side of the upper portion 41, with the walls of the hole 40 protruding from the left and right sides of the upper portion 41. The guide post 2 passes through both the lower portion 42 and the upper portion 41.
[0028] Furthermore, guide post 2 has a stopper step 20 located at its upper end, giving it a thicker top and narrower bottom shape. Accordingly, the hole through which the sliding block 4 engages with the guide post 2 is a stepped hole 40. The stopper step 20 cooperates with the stepped hole 40 to prevent the sliding block 4 from disengaging from the guide post 2 during its upward and downward movement.
[0029] The anti-error magnets 5 are fixed to the top of the slider 4, also known as the upper portion 41. They are arranged in a circular pattern, alternating between north and south poles. To align with the stop assembly 10' of the laser projection product being assembled, the anti-error magnets 50 are identical in number and position to the arcuate grooves 120' on the positioning inner ring 12'.
[0030] Furthermore, the upper surface of the sliding block 4 is provided with a first stopper 43 and a second stopper 44. The first stopper 43 cooperates with the metal plate 11' of the locking assembly 10' to limit the position of the metal plate 11'. Specifically, the first stopper 43 comprises four stopper pins, which cooperate with four holes in the metal plate 11' to limit the position of the metal plate 11'. The second stopper 44 cooperates with the positioning inner ring 12' to limit the position of the positioning inner ring 12'. Specifically, the second stopper 44 and the positioning inner ring 12' also achieve positional limitation through the cooperation of pins and holes.
[0031] like Figure 4 As shown, when the magnetic error-proofing fixture of the present invention is used, first, the metal plate 11' of the stop assembly 10' to be assembled is placed on the top of the sliding block 4, and the metal plate 11' can be accurately placed in place by cooperating with the first limiting member 43 and the hole on the metal plate 11'. The metal plate 11' is firmly located on the top of the sliding block 4 due to the suction force of the error-proofing magnet 50. In this state, the metal plate 11' and the guide column 2 have an overlapping area S; then, the positioning inner ring 12' is placed on the metal plate 11', and the positioning inner ring 12' is placed in place by cooperating with the second limiting member 44 and the hole on the positioning inner ring 12'. In this state, The arc groove 120' of the positioning inner ring 12' corresponds to the anti-error magnet 50 one by one; at this time, the stop magnets 13' are placed into the arc grooves 120' one by one. When placing, if the polarity of the stop magnet 13' is the same as that of the anti-error magnet 50, they will repel each other and the stop magnet 13' cannot be installed in place. On the contrary, if the polarity of the stop magnet 13' is opposite to that of the anti-error magnet 50, they will attract each other and be firmly installed. When the stop magnet 13' is installed, the metal plate 11', the positioning inner ring 12', and the stop magnet 13' are assembled into a stop assembly 10'; finally, the assembled stop assembly 10' is removed from the magnetic anti-error tooling 10, as shown. Figure 5 and Figure 6As shown, the operator presses the sliding block 4 downward. Since the guide column 2 is fixed, the stop assembly 10' has an overlapping area S with the upper surface of the guide column 2. Therefore, the stop assembly 10' will not move downward with the sliding block 4, but will be supported by the upper surface of the guide column 2 and remain in its original position. Through this operation, the stop assembly 10' can be separated from the sliding block 4 more conveniently, so that the stop assembly 10' can be easily removed from the magnetic error-proofing tooling 10.

Any modifications, substitutions, and improvements to the technical solution of the present invention made by a person skilled in the art based on the textual description and accompanying drawings provided herein, without departing from the concept and spirit of the present invention, shall fall within the scope of protection of the present invention.
