Description

Technical Field

[0001] This utility model relates to the field of pen manufacturing technology, specifically to a pen barrel positioning fixture. Background Technology

[0002] In the pen production process, various processing and assembly operations are required on the pen barrel, such as pen tip installation, ink filling, and pen cap assembly. Pen barrel positioning fixtures can ensure the accurate position of the pen barrel in each process, thereby improving production efficiency and product quality.

[0003] The existing pen barrel positioning fixture has a relatively simple structure. It usually uses a single positioning base with a groove to place the pen barrel. When positioning the pen barrel, a positioning base with a groove of appropriate depth is usually selected according to the length of the pen barrel, and then the pen barrel is inserted into the groove on the positioning base.

[0004] Existing pen barrel positioning tools have the following problems: In order to ensure accurate positioning of the pen barrel, the required groove depth varies when dealing with pen barrels of different lengths, while the groove depth of the positioning base is fixed. Therefore, it is necessary to select a suitable positioning base according to the requirements during use. To address this, we propose a pen barrel positioning fixture. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a pen barrel positioning fixture. After the pen barrel is inserted into the groove, the positioning mechanism is adjusted so that it can fix pen barrels of different lengths within the extension limit of the electric push rod. There is no need to consider the depth of the groove on the positioning base, which increases the applicability of the positioning fixture and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pen barrel positioning fixture, including a positioning base, the upper surface of which is provided with uniformly distributed grooves, and a positioning mechanism;

[0007] Positioning mechanism: It includes a sliding groove, a sliding block, a telescopic rod, a fixed rod, a positioning block, and an adjustment component. The upper surface of the positioning base is provided with evenly distributed sliding grooves. A positioning group is slidably connected between three horizontally adjacent sliding grooves. A positioning group consists of two corresponding sliding blocks. The upper end of each sliding block is provided with an evenly distributed telescopic rod. The telescopic ends of the telescopic rods on the same sliding block are fixedly connected to the lower surface of a fixed rod. The two fixed rods on the same positioning group are provided with evenly distributed positioning blocks on their sides that are close to each other. The upper surface of the positioning base is provided with an adjustment component. After the pen barrel is inserted into the groove, the positioning mechanism can be adjusted so that it can fix pen barrels of different lengths within the telescopic limit of the electric push rod, without considering the depth of the groove on the positioning base, thus increasing the applicability of the positioning fixture.

[0008] Furthermore, it also includes a controller, which is located on the front side of the positioning base. The input end of the controller is electrically connected to the built-in battery to facilitate the normal operation of the equipment.

[0009] Furthermore, the adjustment assembly includes limiting posts, an adjustment frame, and guide grooves. The upper surface of the positioning base is provided with evenly distributed limiting posts, and an adjustment frame is slidably connected between the four limiting posts. The interior of the adjustment frame is provided with evenly distributed guide grooves, and the left and right sides of the fixing rod are slidably connected to the interior of the adjacent guide grooves to facilitate the adjustment of the height of the positioning rod.

[0010] Furthermore, an electric push rod is provided in the mounting hole on the upper surface of the positioning base. The upper end of the telescopic shaft of the electric push rod is fixedly connected to the lower surface of the adjustment frame. The input end of the electric push rod is electrically connected to the output end of the controller, which facilitates driving the adjustment frame to move.

[0011] Furthermore, the positioning mechanism also includes a drive assembly, which includes a bidirectional lead screw, a first bevel gear, a rotating shaft, and a second bevel gear. The bidirectional lead screw is rotatably connected to both the front and rear sides of the interior of the positioning base. The front and rear sides of the outer surface of the bidirectional lead screw are threadedly connected to the threaded holes at the right ends of the adjacent sliders. The end of the bidirectional lead screw near the center of the positioning base is provided with a first bevel gear. The interior of the positioning base is rotatably connected to a second bevel gear via a rotating shaft. The first bevel gear is meshed with the same second bevel gear, which facilitates the normal operation of the driving positioning mechanism.

[0012] Furthermore, the positioning base is equipped with a motor, the right end of the motor's output shaft is fixedly connected to the left end of the rotating shaft, and the input end of the motor is electrically connected to the output end of the controller to provide driving force.

[0013] Furthermore, the positioning mechanism also includes a limiting rod. A limiting rod is provided on the left side of the interior of the positioning base. The sliding hole at the left end of the slider is slidably connected to the outer surface of a limiting rod, which facilitates the sliding and limiting of the slider.

[0014] Furthermore, the positioning block is provided with rubber pads on the arc-shaped surface on the side near the central axis of the corresponding groove, which facilitates soft contact with the pen barrel.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This pen barrel positioning fixture has the following advantages:

[0016] After the pen barrel is inserted into the groove, the telescopic shaft of the electric push rod drives the adjusting frame to move up and down along the limiting post. Under the guidance and restriction of the telescopic rod, the fixed rod moves up and down through the guide groove, causing the positioning block to move up and down. By adjusting the height of the positioning block, it can fix pen barrels of different lengths within the telescopic limit of the electric push rod. When the positioning block moves to the appropriate position, the two sliders on the same positioning group move towards each other through the control of the drive component, causing the positioning block to move and clamp and fix the pen barrel through the rubber pad. There is no need to consider the depth of the groove on the positioning base, which increases the applicability of the positioning fixture. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-4 This embodiment provides a technical solution: a pen barrel positioning fixture, including a positioning base 1, the upper surface of the positioning base 1 is provided with uniformly distributed grooves 4, a positioning mechanism 3, and a controller 2, the controller 2 is disposed on the front side of the positioning base 1, the input end of the controller 2 is electrically connected to a built-in battery, and the pen barrel is inserted into the grooves 4 on the positioning base 1.

[0024] Positioning mechanism 3 includes a slide groove 31, a slider 32, a telescopic rod 34, a fixed rod 35, a positioning block 36, and an adjusting assembly 38. The upper surface of the positioning base 1 has evenly distributed slide grooves 31. A positioning group is slidably connected between three horizontally adjacent slide grooves 31. Each positioning group consists of two corresponding sliders 32. The upper end of each slider 32 is provided with an evenly distributed telescopic rod 34. The telescopic ends of the telescopic rods 34 on the same slider 32 are fixedly connected to the lower surface of a fixed rod 35. The two fixed rods 35 on the same positioning group have evenly distributed positioning blocks 36 on their sides closest to each other. The upper surface of the positioning base 1 is provided with an adjusting assembly 38, which includes a limiting post 381, an adjusting frame 382, ​​and a guide. The upper surface of the positioning base 1 is provided with evenly distributed limiting posts 381. An adjusting frame 382 is slidably connected between the four limiting posts 381. The interior of the adjusting frame 382 is provided with evenly distributed guide grooves 383. The left and right sides of the fixing rod 35 are slidably connected to the interior of the adjacent guide grooves 383. An electric push rod 6 is provided in the mounting hole on the upper surface of the positioning base 1. The upper end of the telescopic shaft of the electric push rod 6 is fixedly connected to the lower surface of the adjusting frame 382. (When the telescopic rod 34 and the electric push rod 6 are working, the forces they experience are divided into axial force and radial force. The telescopic rod 34 and the electric push rod 6 mainly bear the force in the telescopic direction, i.e., the axial force. When the telescopic rod 34 and the electric push rod 6 are subjected to radial force, due to the presence of the limiting posts 381, the telescopic rod 34 and the electric push rod 6 are subjected to radial force.) The push rod 6 is subjected to force protection limit to make the telescopic rod 34 and the electric push rod 6 more stable during operation. The input end of the electric push rod 6 is electrically connected to the output end of the controller 2. The positioning mechanism 3 also includes a drive assembly 37, which includes a bidirectional lead screw 371, a first bevel gear 372, a rotating shaft 373 and a second bevel gear 374. The bidirectional lead screw 371 is rotatably connected to both the front and rear sides of the interior of the positioning base 1. The front and rear sides of the outer surface of the bidirectional lead screw 371 are threaded to the threaded holes at the right end of the adjacent slider 32. (The exposed part of the outer surface of the bidirectional lead screw 371 is fitted with a bellows, which are fixedly connected between the side of the slider 32 and the inner wall of the positioning base 1. The presence of the bellows ensures the sealing and lubrication of the bidirectional lead screw 371.) Each end of the bidirectional lead screw 371 near the center of the positioning base 1 is equipped with a bevel gear 372. Inside the positioning base 1, a bevel gear 374 is rotatably connected via a rotating shaft 373. Both bevel gears 372 and 374 mesh with the same bevel gear 374. A motor 5 is located inside the positioning base 1. The right end of the motor 5's output shaft is fixedly connected to the left end of the rotating shaft 373. The input end of the motor 5 is electrically connected to the output end of the controller 2. The positioning mechanism 3 also includes a limit rod 33. A limit rod 33 is located on the left side inside the positioning base 1. The sliding holes at the left end of the slider 32 are slidably connected to the outer surface of a limit rod 33. Rubber pads 7 are provided on the arc-shaped surface of the positioning block 36 near the central axis of the corresponding groove 4. The electric push rod 6 operates under the control of the controller 2.The telescopic shaft of the electric push rod 6 drives the adjusting frame 382 to move up and down along the limiting post 381. Under the guidance and restriction of the telescopic rod 34, it drives the fixing rod 35 to move up and down through the guide groove 383, thereby causing the positioning block 36 to move up and down. By adjusting the height of the positioning block 36, it can fix pen barrels of different lengths within the telescopic limit of the electric push rod 6. When the positioning block 36 moves to the appropriate position, the output shaft of the motor 5 drives the rotating shaft 373 to rotate through the control of the controller 2. The rotation of the rotating shaft 373 is achieved through mutual meshing. The bevel gears 372 and 374 drive the bidirectional lead screw 371 to rotate. Under the constraint of the limiting rod 33, the rotation of the bidirectional lead screw 371 causes two sliders 32 on the same threaded positioning assembly to move towards each other along the slide groove 31. The movement of the sliders 32 drives the positioning block 36 to move via the telescopic rod 34 and the fixing rod 35. The movement of the positioning block 36 clamps and fixes the pen barrel through the rubber pad 7, achieving the positioning of the pen barrel. Due to the presence of the rubber pad 7, soft contact is achieved between the positioning mechanism 3 and the pen barrel, reducing damage to the pen barrel.

[0025] The working principle of the pen barrel positioning fixture provided by this utility model is as follows: Under the control of the controller 2, the electric push rod 6 operates. The telescopic shaft of the electric push rod 6 drives the adjusting frame 382 to move up and down along the limiting post 381. Under the guidance and restriction of the telescopic rod 34, the fixed rod 35 moves up and down through the guide groove 383, thereby causing the positioning block 36 to move up and down. By adjusting the height of the positioning block 36, it can fix pen barrels of different lengths within the telescopic limit of the electric push rod 6. When the positioning block 36 moves to the appropriate position, the pen barrel is inserted into the groove 4 on the positioning base 1. Under the control of the controller 2, the motor... 5. The working output shaft drives the rotating shaft 373 to rotate. The rotation of the rotating shaft 373 drives the bidirectional lead screw 371 to rotate through the meshing bevel gear 372 and bevel gear 374. Under the restriction of the limit rod 33, the rotation of the bidirectional lead screw 371 drives the two sliders 32 on the same positioning group connected by threads to move towards each other along the slide groove 31. The movement of the sliders 32 drives the positioning block 36 to move through the telescopic rod 34 and the fixing rod 35. The movement of the positioning block 36 clamps and fixes the pen barrel through the rubber pad 7, realizing the positioning work of the pen barrel. Due to the presence of the rubber pad 7, the positioning mechanism 3 achieves soft contact with the pen barrel, reducing damage to the pen barrel.

[0026] It is worth noting that the controller 2 disclosed in the above embodiments can be an RX13T series, the motor 5 can be an EC series brushless DC motor, and the controller 2 controls the operation of the motor 5 and the electric push rod 6 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
