Description

Technical Field

[0001] This application relates to the technical field of door leaf processing, and particularly relates to a tapping machine. Background Art

[0002] In the traditional tapping process, the processing flow of door leaves often involves multiple working steps and repeated equipment conversions. First, the door leaf needs to be lifted and transported to the locking assembly station. In this stage, dimensional measurement and scribing are mainly carried out to determine the installation position. This link not only requires the operator to have high-precision measurement skills, but also takes a long time.

[0003] Next, the door leaf is to be transferred to the drill press station. At this station, according to the positioning of the previous scribing, the door leaf is drilled, and then tapped to facilitate the installation of the locking assembly. Finally, the door leaf is lifted and transported back to the locking assembly station for actual installation.

[0004] Drilling and tapping are precision processes that require ensuring the accuracy of the hole position and the quality of the thread. However, this step also requires frequent equipment adjustment and positioning. Due to the weight and volume of the door leaf, frequent lifting and transportation not only increase the labor intensity of workers, but also pose potential safety risks for each transfer. At the same time, it may lead to a decrease in assembly accuracy due to positioning errors, affecting the overall product quality. Content of the Utility Model

[0005] Therefore, this application provides a tapping machine to solve the problems of frequent lifting and transportation, low assembly degree, and low product quality existing in the prior art.

[0006] To achieve the above object, this application provides the following technical solutions:

[0007] A tapping machine includes a vertical shaft, a first main arm, a second main arm, a magnetic drill, and a tapping machine. The vertical shaft is vertically fixed on the ground. The first main arm is slidably connected to the vertical shaft. An elevating mechanism for driving the first main arm to lift and lower is provided on the vertical shaft, and the first main arm can rotate around the vertical shaft along the axial direction. One end of the first main arm away from the vertical shaft is rotatably connected to the second main arm, and both the first main arm and the second main arm are horizontally arranged. The magnetic drill and the tapping machine are both rotatably connected to one end of the second main arm away from the first main arm.

[0008] Optionally, the elevating mechanism includes a first lead screw and a first threaded outer sleeve. The first lead screw is rotatably connected to the vertical shaft through a connecting seat. The first threaded outer sleeve is in threaded cooperation with the first lead screw, and the first threaded outer sleeve is fixed to the first main arm. The outer contour of the cross-section of the first threaded outer sleeve is polygonal.

[0009] Optionally, a fixing device slidably connected to the vertical shaft is further provided on the vertical shaft. The fixing device is located below the first main arm and can be fixed on the vertical shaft to support the first main arm.

[0010] Optionally, a magnetic base is installed on the second main arm. The magnetic base includes a connecting structure and a magnetic frame assembly. The connecting structure is used to hoist the magnetic frame assembly below the second main arm.

[0011] Optionally, the connecting structure includes a second lead screw and a second threaded outer sleeve. The second threaded outer sleeve is fixed on the second main arm with its axis vertical. The second lead screw is in threaded cooperation with the second threaded outer sleeve. The magnetic frame assembly is installed at the bottom of the second lead screw.

[0012] Optionally, a guide rod is vertically installed on the magnetic frame assembly. The upper end of the guide rod is inserted into the second main arm and can slide up and down relative to the second main arm.

[0013] Optionally, a vertical rod is coaxially fixed at the top of the vertical shaft. A bearing assembly is installed at the top of the vertical rod. Balancing members are installed on both the bearing assembly and the area of the first main arm far from the vertical shaft. A pull rope is connected between the two balancing members.

[0014] Optionally, a wire tightener is installed on the pull rope.

[0015] Optionally, a tool box is installed on the first main arm.

[0016] Optionally, the bottom of the vertical shaft is inserted into the ground through embedded iron and fixed by pouring concrete.

[0017] Compared with the prior art, the present application has at least the following beneficial effects:

[0018] 1. Both the tapping machine and the magnetic drill are installed on the second main arm, and both the second main arm and the first main arm can rotate, so that the positions of the tapping machine and the magnetic drill are adjustable. It is possible to punch and tap the door leaf in sequence while the door leaf remains fixed, without frequent hoisting of the door leaf, reducing the labor intensity of workers. Moreover, the door leaf remains stationary during the operation, avoiding the influence of positioning errors on the assembly accuracy and helping to improve the overall product quality.

[0019] 2. The first main arm is lifted and lowered by the lifting mechanism, driving the second main arm, the magnetic drill and the tapping machine to lift and lower, which is convenient for adapting to the specifications and placement positions of the door leaf.

[0020] 3. The setting of the fixing device can support the first main arm and prevent the first main arm from sliding down.

[0021] 4. By adsorbing the door leaf with the magnetic base, the position of the second main arm and the door leaf can be relatively fixed, ensuring the stable progress of the punching and tapping operations.

[0022] 5. The arrangement of the pull rope can provide an upward pulling force to the end of the first main arm away from the vertical axis, reduce its deformation, and improve the overall stability of the first main arm. Description of the Drawings

[0034] The following further details the present application through specific embodiments in conjunction with the accompanying drawings.

[0035] In the description of the present application: Unless otherwise specified, the meaning of "a plurality" is two or more. Terms such as "first", "second", "third", etc. in the present application are intended to distinguish the objects being referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0036] Terms such as "upper", "lower", "left", "right", "middle", etc. cited in the present application are generally indications of the general relative position relationship for the convenience of intuitively understanding with reference to the accompanying drawings, and are not absolute limitations on the position relationship in the actual product.

[0037] A tapping machine, referring to Figures 1-3 , includes a vertical axis 1, a first main arm 2, a second main arm 3, a magnetic drill 4, and a tapping machine 5. The vertical axis 1 is vertically fixed on the ground. The specific fixing method is: An embedded iron 6 is installed at the bottom of the vertical axis 1. The embedded iron 6 includes a base 7. Sixteen vertical anchor bars 8 with a thread diameter of φ20 are evenly distributed at the bottom of the base 7. The length of the anchor bars 8 is 400 mm. Eight M20 screw holes 9 and eight corresponding plugs 10 are also provided on the base 7. The plugs 10 are at the bottom of the screw holes 9. First, dig a foundation pit underground, bury the embedded iron 6 into the foundation pit, and then pour concrete into the foundation pit to form a foundation for fixing the vertical axis 1.

[0038] Referring to Figure 1 and Figure 4, the first main arm 2 is slidably connected to the vertical shaft 1. An elevating mechanism 11 for driving the first main arm 2 to move up and down is provided on the vertical shaft 1, and the first main arm 2 can rotate around the vertical shaft 1 along the axial direction. Specifically, a main shaft hole is vertically formed at one end of the first main arm 2. A main shaft outer sleeve 12 and a copper sleeve 13 are fixed in the main shaft hole. Both the main shaft outer sleeve 12 and the copper sleeve 13 are sleeved on the vertical shaft 1 to ensure the stable connection between the first main arm 2 and the vertical shaft 1.

[0039] Among them, one end of the bottom surface of the first main arm 2 away from the vertical shaft 1 gradually slopes upward. This end is rotatably connected to the second main arm 3 through a connecting sleeve. The second main arm 3 is located below the end of the first main arm 2. In this embodiment, the top surface of the first main arm 2 and the second main arm 3 are both horizontally arranged. The magnetic drill 4 and the tapping machine 5 are both rotatably connected to one end of the second main arm 3 away from the first main arm 2.

[0040] The door leaf 14 is stabilized on one side of the vertical shaft 1 through a bracket. The worker manually pushes and pulls the first main arm 2 and the second main arm 3 to drive them to rotate until the magnetic drill 4 and the tapping machine 5 move to directly above the designated position of the door leaf 14 to drill and tap the door leaf 14. During this process, the position of the door leaf 14 does not need to change, and only the magnetic drill 4 and the tapping machine 5 need to be adjusted. In this embodiment, the bracket is composed of multiple angle steels. Before operating on the door leaf 14, the angle steels are buckled on the ground, and then the door leaf 14 is placed on the angle steels to stably support the door leaf 14 by the angle steels.

[0041] Refer to Figure 1 and Figure 5 , the elevating mechanism 11 includes a first lead screw 15 and a first threaded outer sleeve 16. The same connecting seat 17 is connected between the first lead screw 15 and the vertical shaft 1. Bearing assemblies 27 are provided between the first lead screw 15 and the vertical shaft 1 and the connecting seat 17 respectively, so that the first lead screw 15 can rotate while the vertical shaft 1 can remain fixed to realize the rotational connection between the first lead screw 15 and the vertical shaft 1. The first threaded outer sleeve 16 is in threaded cooperation with the first lead screw 15, and the first threaded outer sleeve 16 is located below the connecting seat 17. Among them, the outer contour of the cross-section of the first threaded outer sleeve 16 is polygonal. A polygonal through hole matching with the first threaded outer sleeve 16 is vertically formed in the area of the first main arm 2 close to the vertical shaft 1 and is fixedly connected to the first threaded outer sleeve 16. The polygonal outer contour enables the first threaded outer sleeve 16 and the first main arm 2 to remain relatively fixed and prevents the first threaded outer sleeve 16 from rotating with the first lead screw 15. Therefore, when driving the first lead screw 15 to rotate, the first threaded outer sleeve 16 moves up and down along the first lead screw 15 under the action of the threaded cooperation to drive the first main arm 2 to move up and down on the vertical shaft 1.

[0042] In this embodiment, the outer contour of the first threaded outer sleeve 16 is trapezoidal. And a handle is installed at the top of the first lead screw 15 to facilitate driving the first lead screw 15 to rotate.

[0043] Referring to Figure 6 , further, a fixing device 18 capable of moving up and down on the vertical shaft 1 is provided on the vertical shaft 1, and the fixing device 18 is located below the first main arm 2. In this embodiment, the main body of the fixing device 18 is a deformable ring, an opening is provided on the ring, and two mounting ears with screw holes extend outward from the opening. Among them, when the opening of the ring is closed, its inner diameter is smaller than the outer diameter of the vertical shaft 1. Therefore, after the two mounting ears are fixed together by screws, the fixing device 18 can clamp the vertical shaft 1 to be fixed on the vertical shaft 1. After adjusting the height of the first main arm 2, slide the fixing device 18 to the lower part of the first main arm 2 and make it contact with the first main arm 2, and then fix the fixing device 18 on the vertical shaft 1 to support the first main arm 2 and prevent the first main arm 2 from sliding down.

[0044] Referring to Figure 7 , in order to ensure the stability of the drilling and tapping operations, a magnetic base 19 is installed in the area of the second main arm 3 far from the first main arm 2. The magnetic base 19 includes a connecting structure and a magnetic frame assembly. The magnetic frame assembly is used to adsorb the door leaf 14, and the connecting structure is used to hoist the magnetic frame assembly below the second main arm 3.

[0045] Among them, the magnetic frame assembly includes a cross plate 20 and an electromagnet 21 installed below the cross plate 20. The connecting structure includes a second lead screw 22 and a second threaded outer sleeve 23. The second threaded outer sleeve 23 is fixed on the second main arm 3 and its axis is vertical. The second lead screw 22 is in threaded cooperation with the second threaded outer sleeve 23, and the cross plate 20 is installed at the bottom of the second lead screw 22 through a plurality of bolts. Therefore, when the second lead screw 22 is driven to rotate, through the threaded cooperation, the second lead screw 22 can move up and down relative to the second threaded outer sleeve 23 and the second main arm 3, and drive the magnetic frame assembly to move up and down to adapt to the distance between the second main arm 3 and the door leaf 14, smoothly adsorb the door leaf 14, and relatively fix the second main arm 3 and the door leaf 14.

[0046] To improve the stability of the lifting of the magnetic frame assembly, a plurality of guide rods 24 are vertically fixed on the cross plate 20. The upper end of each guide rod 24 is inserted upward into the second main arm 3 and can slide up and down relative to the second main arm 3. Through the sliding cooperation between the guide rod 24 and the second main arm 3, the purpose of stable lifting of the magnetic frame assembly is achieved.

[0047] Further, a hand wheel 25 is installed at the upper end of the second lead screw 22 to facilitate driving the second lead screw 22 to rotate.

[0048] Referring to Figure 8, a vertical rod 26 is coaxially fixed to the top of the vertical shaft 1. A bearing assembly 27 is installed at the top of the vertical rod 26. Balance members 28 are installed in the areas between the bearing assembly 27 and the end of the first main arm 2 away from the vertical shaft 1. A pull rope 29 is connected between the two balance members 28. The pull rope 29 can lift the end of the first main arm 2 away from the vertical shaft 1 upward, preventing the distal end of the first main arm 2 from sinking, so as to keep the first main arm 2 stable; in addition, it can also play a role in saving effort when the first main arm 2 and the second main arm 3 rotate. The setting of the bearing assembly 27 can help the pull rope 29 adapt to the rotation of the first main arm 2, preventing the pull rope 29 from winding around the vertical rod 26 when the first main arm 2 rotates.

[0049] Furthermore, since the lifting mechanism 11 will drive the first main arm 2 to lift and lower, in order to enable the pull rope 29 to always have a stable pulling force on the distal end of the first main arm 2, a wire tightener 30 is installed on the pull rope 29 to ensure that the pull rope 29 is always kept in a taut state.

[0050] To facilitate the operation of workers, a toolbox 31 is installed at a position on the top of the first main arm 2 close to the vertical shaft 1 to hold the tools that will be used during the operation, avoiding the workers running around, saving labor, and facilitating the improvement of efficiency.

[0051] In this embodiment, in order to reduce friction, copper sleeves 13 can be provided between the first main arm 2 and the connecting sleeve, between the second main arm 3 and the connecting sleeve, between the tapping machine 5 and the second main arm 3, and between the magnetic drill 4 and the second main arm 3, improving the service life of the entire device.

[0052] The implementation principle of the embodiment of this application is: when processing the door leaf 14, first use brackets such as angle steel to stabilize the door leaf 14 near the vertical shaft 1, and then adjust the heights of the tapping machine 5 and the magnetic drill 4 through the lifting mechanism 11. Manually push and pull the first main arm 2 and the second main arm 3 until the tapping machine 5 and the magnetic drill 4 are directly above the designated position of the door leaf 14. At this time, rotate the handwheel 25 to drive the electromagnet 21 to approach the door leaf 14 and adsorb on the door leaf 14 to stabilize the second main arm 3, facilitating the drilling and tapping of the door leaf 14.

[0053] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be regarded as within the scope described in this specification.
