[0001] This utility model belongs to the field of circular line drawing technology, and specifically relates to a circular line drawing device. Background Technology

[0002] In the actual production process of magnetic products, because customers have multiple suppliers, they need to distinguish products from different manufacturers and mark them accordingly. Alternatively, after completing a certain process, the product's appearance needs to be marked to indicate that that process has been completed.

[0003] With the increasing number of small-volume products and the rising demands of customers, manual line drawing suffers from low efficiency and high labor intensity. Utility Model Content

[0004] The purpose of this invention is to provide a circular line drawing device to solve the problems mentioned in the background art. The circular line drawing device provided by this invention effectively improves line drawing efficiency and reduces labor intensity.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a circular line drawing device, including a worktable, a drive component and a support component installed on the upper part of the worktable, one end of a fixture connected to the output end of the drive component, the other end of the fixture placed on the upper part of the support component, and a line drawing component corresponding to the fixture installed on the upper part of the worktable.

[0006] To achieve axial and radial fixation of the ring product, the fixture further includes a rubber rod with a mandrel penetrating its interior, the outer diameter of the mandrel being larger than the inner diameter of the rubber rod.

[0007] To further facilitate the positioning of the ring-shaped product, a limiting ring is provided on one end of the rubber rod.

[0008] To facilitate the connection between the mandrel and the connecting sleeve, a connecting ring is further provided on one end of the mandrel. The drive assembly includes a motor mount, on which a speed-regulating motor is mounted. The output end of the speed-regulating motor is connected to the connecting sleeve, and a magnet is connected inside the connecting sleeve.

[0009] To further facilitate contact between the drawing pen and the circular product by pushing the clamping block, the drawing assembly includes two parallel sliding guide rails, with clamping blocks connected to the sliders of the sliding guide rails, and several drawing pens clamped on the clamping blocks.

[0010] To cushion the clamping blocks and reduce the impact of the drawing pen on the circular products, a buffer corresponding to the clamping blocks is further installed above the worktable.

[0011] To facilitate the adjustment of the height and relative position of the two follower wheels according to the mandrels of different diameters, thereby ensuring that the mandrel is in a horizontal state, the support further includes a base, on which an adjustment block is connected.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-5 The present invention provides the following technical solution: a circular line drawing device, including a workbench 1, a drive component 3 and a support component 5 installed on the upper part of the workbench 1 respectively, one end of a fixture 2 connected to the output end of the drive component 3, the other end of the fixture 2 placed on the upper part of the support component 5, and a line drawing component 4 corresponding to the fixture 2 installed on the upper part of the workbench 1.

[0027] By adopting the above technical solution, this utility model uses a fixture 2 to install the circular ring product to be marked, drives the fixture 2 to rotate through the drive component 3, and uses the marking component 4 to act on the circular ring product to achieve marking. It can mark multiple circular ring products at one time, and has the characteristics of high marking efficiency and low labor intensity.

[0028] Specifically, the jig 2 includes a rubber rod 21, the outer diameter of which is equal to or slightly smaller than the inner diameter of the ring product. A mandrel 23 runs through the inside of the rubber rod 21. The outer diameter of the mandrel 23 is larger than the inner diameter of the rubber rod 21. Lubricant is applied to the circumference of the mandrel 23 to facilitate the insertion of the mandrel 23 into the rubber rod 21.

[0029] By adopting the above technical solution, the circular ring product to be marked is sequentially threaded onto the rubber rod 21, and then the mandrel 23 is inserted into the rubber rod 21, causing the rubber rod 21 to expand and clamp the circular ring product, thereby achieving axial and radial fixation of the circular ring product.

[0030] Specifically, a connecting ring 24 is provided on one end of the spindle 23, and the connecting ring 24 is made of magnetic material; the drive assembly 3 includes a motor base 31, a speed-regulating motor 32 is installed on the motor base 31, a connecting sleeve 33 is connected to the output end of the speed-regulating motor 32, and a magnet 34 is connected inside the connecting sleeve 33. The speed-regulating motor 32 is a 2IK6RGN-C / 100K motor + reducer from Songgang.

[0031] By adopting the above technical solution, the mandrel 23 and the connecting sleeve 33 are connected by the magnetic attraction of the magnet 34 to the connecting ring 24. The magnetic attraction is greater than the torque when the drawing pen acts on the ring product. The speed-regulating motor 32 drives the mandrel 23 to rotate, thereby driving the ring product to rotate. This utility model uses the speed-regulating motor 32 as the power end. The output shaft of the speed-regulating motor 32 can rotate very slowly, so that the fixture 2 can be replaced without stopping the machine.

[0032] Specifically, the line drawing component 4 includes two parallel slider guide rails 43. A clamping block 41 is connected to the slider of the slider guide rail 43. Several line drawing pens 42 are clamped on the clamping block 41. The clamping block 41 includes an upper clamping block and a lower clamping block, which are connected by bolts.

[0033] By adopting the above technical solution, the clamping block 41 is pushed to make the drawing pen 42 come into contact with the circular product.

[0034] Example 2

[0035] The difference between this embodiment and embodiment 1 is that, specifically, a limiting ring 22 is provided on one end of the rubber rod 21.

[0036] The above technical solution is used for positioning circular ring products.

[0037] Example 3

[0038] The difference between this embodiment and embodiment 1 is that, specifically, a buffer 6 corresponding to the clamping block 41 is installed above the workbench 1. The buffer 6 is a J-WJR11-1007 model from Yiheda.

[0039] By adopting the above technical solution, the clamping block 41 is buffered, reducing the impact of the drawing pen 42 on the circular product.

[0040] Example 4

[0041] The difference between this embodiment and embodiment 1 is that, specifically, the support member 5 includes a base 51, and an adjusting block 52 is connected to the base 51. The adjusting block 52 has a Y-shaped structure and two symmetrical follower wheels 53 are connected to the adjusting block 52. The vertical end of the adjusting block 52 is provided with a waist groove. The vertical end of the adjusting block 52 is connected to the base 51 by a wing bolt, which facilitates the adjustment of the height of the follower wheels 53. The two inclined ends of the adjusting block 52 are also provided with waist grooves. The follower wheels 53 are installed on the inclined ends by wing bolts. Bearings are installed in the follower wheels 53 to facilitate the adjustment of the relative position of the two follower wheels 53, thereby making it suitable for mandrels 23 of different diameters.

[0042] By adopting the above technical solution, it is convenient to adjust the height and relative position of the two follower wheels 53 according to the different diameters of the spindle 23, thereby ensuring that the spindle 23 is in a horizontal state.

[0043] In summary, this invention uses a fixture 2 to install the circular rings to be marked. The drive assembly 3 rotates the fixture 2, and the marking assembly 4 applies the marking to the rings. This allows for marking multiple rings simultaneously, resulting in high efficiency and low labor intensity. The fixture 2 includes a rubber rod 21 with a mandrel 23 running through it. The outer diameter of the mandrel 23 is larger than the inner diameter of the rubber rod 21. The circular rings to be marked are sequentially threaded onto the rubber rod 21, and then the mandrel 23 is inserted into the rubber rod 21, causing the rubber rod 21 to expand and clamp the rings, thus fixing them axially and radially. This invention uses a speed-regulating motor 32 as the power source, and the mandrel 23 and the connecting sleeve 33 are connected by the magnetic attraction of a magnet 34 to a connecting ring 24. The output shaft of the speed-regulating motor 32 can rotate very slowly, allowing the fixture 2 to be replaced without stopping the machine. The workbench 1 of this invention has a buffer 6 installed above the corresponding clamping block 41 to cushion the clamping block 41 and reduce the impact of the drawing pen 42 on the circular product. The support 5 of this invention allows for adjustment of the height and relative position of the two follower wheels 53 according to the different diameters of the mandrel 23, thereby ensuring that the mandrel 23 is in a horizontal state.
