Description

Technical Field

[0001] The present application relates to the field of medical bed processing equipment, and in particular to a semi-automatic tapping device for a medical bed base. Background Art

[0002] Currently, the operating table on the market includes a base, a support mechanism, a top rotating mechanism, and a bed for the injured to lie flat, which are divided from bottom to top. The bottom side of the base is connected to a universal wheel to achieve the function of moving the operating table, and the upper side of the base is used to cooperate with the support mechanism thread on the upper side of the base.

[0003] In order to connect the base and the supporting mechanism, screw holes need to be drilled in advance on the base to facilitate subsequent assembly. The conventional method of processing screw holes is to manually use a bench drill to first clamp a twist drill to drill a bottom hole on the base, then remove the twist drill and replace it with a tap for tapping to form a screw hole. This method requires repeated replacement of the twist drill and tap, which is time-consuming and labor-intensive and easily affects the tapping efficiency. Utility Model Content

[0019] The following is combined with Figure 1-2 The present invention is further described in detail with specific preferred embodiments.

[0020] In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second" and the like do not indicate the importance of the components, and therefore cannot be understood as limiting the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution, and do not limit the scope of protection of the present invention.

[0021] The present application embodiment discloses a semi-automatic tapping device for a medical bed base. Figure 1 and Figure 2 The semi-automatic tapping device includes a base 1, a slide 2 moving in the horizontal direction is slidably connected to the base 1, two machine heads 3 moving in the vertical direction are slidably connected to the slide 2, the two machine heads 3 are spaced apart and both machine heads 3 are rotatably connected with a core shaft 31, the two core shafts 31 are vertically arranged and the lower ends of the two core shafts 31 are respectively connected with a twist drill 311 and a tap 312, a limiting component 4 for limiting the movement of the slide 2 is provided on the base 1, a lifting unit for driving the machine head 3 to move is provided on the slide 2, and a driving component 6 for driving the core shaft 31 to rotate is provided on the machine head 3.

[0022] like Figure 2 The limiting assembly 4 includes a limiting rod 41, a stud 42 and a limiting nut 43. The limiting rod 41 is arranged on the pedestal 1 and is parallel to the moving direction of the slide 2. The limiting rod 41 is provided with a limiting groove 411 extending along its length direction. One end of the stud 42 is connected to the slide 2, and the other end vertically passes through the limiting groove 411 and is threadedly connected to the limiting nut 43. A handle 431 is fixed to the limiting nut 43. Both ends of the limiting rod 41 are threadedly connected with positioning columns 44, and the two positioning columns 44 pass into the limiting groove 411 parallel to the length direction of the limiting rod 41.

[0023] When the slide 2 moves, the stud 42 is driven to move in the limit groove 411. The operator can turn the positioning column 44 to adjust the distance it extends into the limit groove 411, thereby controlling the movable distance of the slide 2, so that when the stud 42 abuts against the two positioning columns 44 respectively, the positions of the twist drill 311 and the tap 312 are positioned, and the twist drill 311 and the tap 312 can be moved to the same position for direct processing without debugging, which is beneficial to saving time and improving tapping efficiency.

[0024] The lifting unit includes an electric cylinder 5, which is vertically mounted on the slide 2 and the cylinder body of the electric cylinder 5 is hinged to the slide 2, and the driving rod of the electric cylinder 5 is hinged to the machine head 3. The telescopic movement of the driving rod of the electric cylinder 5 drives the machine head 3 to move up and down, and the sliding connection between the machine head 3 and the slide 2 limits the moving direction of the slide 2. The hinged setting of the electric cylinder 5 allows a certain deviation margin for the moving direction of the machine head 3 to avoid jamming.

[0025] like Figure 2 The driving assembly 6 includes a pulley 61 and a servo motor 62. The servo motor 62 is mounted on the machine head 3 and its axis is parallel to the mandrel 31. The pulley 61 is provided with two pulleys, which are coaxially arranged on the mandrel 31 and the motor shaft of the servo motor 62, respectively. The two pulleys 61 are connected by a belt 63. A pressure wheel 64 is rotatably connected to the machine head 3. The pressure wheel 64 is located between the two pulleys 61 and abuts against the belt 63.

[0026] The servo motor 62 drives the motor pulley 61 connected thereto to rotate, and the pulley 61 drives another pulley 61 to rotate through the belt 63, so that the mandrel 31 drives the twist drill 311 or the tap 312 to rotate. The servo motor 62 can perform precise control to adjust the rotation speed of the twist drill 311 and the tap 312 to improve the tapping quality. The pressure wheel 64 generates thrust on the belt 63, so that the belt 63 remains taut, ensuring the transmission between the belt 63 and the pulley 61.

[0027] like Figure 1 and Figure 2 During processing, the operator first moves the slide 2 so that the twist drill 311 is aligned with the drilling position on the base, screws the positioning column 44 corresponding to the stud 42 to abut against it, rotates the wrench to drive the limit nut 43 to abut against the limit rod 41, fixes the slide 2, starts the servo motor 62 and the electric cylinder 5, the electric cylinder 5 drives the machine head 3 to descend, and the rotating twist drill 311 drills the base. After the drilling is completed, the electric cylinder 5 drives the machine head 3 to rise, and the servo motor 62 stops.

[0028] The operator reverses the wrench to loosen the limit nut 43, moves the slide 2 to make the tap 312 correspond to the drilled bottom hole, twists the positioning column 44 corresponding to the stud 42 on this side to abut against it, rotates the wrench to drive the limit nut 43 and the limit rod 41 to abut against it, fixes the slide 2, starts the servo motor 62 and electric cylinder 5 corresponding to the machine head 3, the electric cylinder 5 drives the machine head 3 to descend, and the rotating tap 312 taps the bottom hole. After the tapping is completed, the electric cylinder 5 drives the machine head 3 to rise, and the servo motor 62 stops.

[0029] Since the positions of the twist drill 311 and the tap 312 are positioned by the positioning column 44, the operator only needs to move the slide 2 to drive the stud 42 to abut against the two positioning columns 44 to determine the positions of the twist drill 311 and the tap 312. Therefore, no debugging is required in the second and subsequent base processing, and the step of replacing the twist drill 311 and the tap 312 is reduced, saving debugging and replacement time and improving the base tapping processing efficiency. In addition, the position of the positioning column 44 is adjustable, which facilitates the need to perform tapping processing on different positions of the base.
