Description

Technical Field

[0001] The invention belongs to the technical field of gearbox processing, and in particular relates to a drilling device for gearbox case processing. Background Art

[0002] Automobile gearboxes are often called "gearboxes" in automobiles and "speed machines" in industrial machinery. They are mechanical or hydraulic equipment for mechanical power conversion. The automobile gearbox housing requires multiple processing steps, among which drilling equipment is required for drilling operations. However, there are many specifications for the orientation of the holes on the gearbox housing. In the existing drilling process, after the gearbox housing is fixed, the housing cannot be adjusted, which delays the drilling process and affects the processing efficiency. Summary of the invention

[0003] In view of this, the present invention discloses a drilling device for gearbox case processing, which aims to solve the problem that the case cannot be adjusted after the gearbox case is fixed during the existing drilling process.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] The top of the support leg is provided with a toothed structure, and the bottom of the toothed structure is provided with a toothed structure, and the toothed structure is vertically connected to the toothed structure.

[0006] In this solution, the gearbox housing is placed on the mounting seat, and the threaded rod is rotated forward. The threaded rod drives the clamping seat to move toward the housing until the clamping seat and the housing are against each other. The housing is clamped and fixed in multiple directions by using multiple clamping seats to improve the clamping stability of the housing. Then, the housing is driven to move under the drilling equipment through the sliding base to perform drilling operations. When the drilling angle needs to be adjusted, the support seat is deflected by the rotating shaft, and the support seat drives the guide seat to move through the support rod. Then, the latch is installed and the support rod is locked to support the support seat, thereby adjusting the inclination angle of the housing, and then adjusting the drilling angle. In addition, the position of the housing can be adjusted by sliding the base and rotating the mounting seat, and the housing can be adjusted in all directions to cooperate with drilling operations of different specifications.

[0007] Furthermore, the clamping seat is provided with a clamping portion extending upward from the sliding groove, and the clamping portion includes a plurality of clamping blocks, the top ends of the clamping blocks are fixed with rotating shafts, and the bottom ends of the clamping blocks are rotatably connected to adjacent rotating shafts, wherein the clamping blocks located at the bottom are fixedly connected to the clamping seat; the end surfaces of the clamping blocks away from the axis of the mounting seat are hinged with support rods, and connecting seats are provided between adjacent clamping blocks, and the support rods are hinged to adjacent connecting seats; positioning rods perpendicular to the rotating shafts are fixed to the rotating shafts, and annular blocks are rotatably connected to the connecting seats, and the annular blocks are threadedly connected to the corresponding positioning rods.

[0008] In this solution, when the clamping seat abuts against the box body, the annular block is rotated from bottom to top in sequence, and the rotation of the annular block drives the connecting seat to move toward the clamping block on the support rod, and then the adjacent clamping block at the upper end is pushed by the upper support rod to deflect toward the axis of the mounting seat until the adjacent clamping block at the upper end abuts against the box body, thereby forming multi-point clamping and support for the box body, improving the stability of the box body clamping, and at the same time being able to adapt to the irregular end faces of boxes of different specifications.

[0009] Furthermore, the support rod includes a fixed sleeve hinged on the guide seat at one end, a support ring is coaxially slidably arranged inside the fixed sleeve, and a positioning pin for limiting the support ring is detachably connected to the fixed sleeve; a moving rod is sleeved inside the support ring, the outer diameter of the moving rod is smaller than the inner diameter of the support ring, and the moving rod is hinged to the bottom of the support seat; a plurality of sliding grooves arranged along the axis of the support ring are opened on the inner wall of the support ring, and a sliding seat is slidably connected in the sliding grooves, and the side walls of the sliding grooves are provided with grooves facing the axis of the support ring, a limiting rod is slidably connected in the groove, and the end of the limiting rod is arc-shaped, and a limiting rod is arranged between the limiting rod and the groove. There is an elastic reset part, and a plurality of limit holes cooperating with the limit rod are provided on the sliding seat; connecting grooves are provided between the grooves adjacent to the circumference of the support ring, and the support sleeve is connected to the connecting groove by radial sliding along the support ring, and the two ends of the support sleeve are coaxially slidably connected with connecting rods fixedly connected to the adjacent limit rods; synchronous grooves are connected between the grooves adjacent to the axial direction of the moving rod, and a synchronous rod with a diameter smaller than the inner diameter of the synchronous groove is arranged in the synchronous groove, and the two ends of the synchronous rod are fixedly connected to the adjacent limit rods; the sliding seat is obliquely hinged with a conduction rod hinged to the side wall of the moving rod, and the adjacent conduction rods along the axial direction of the support ring are inclined in opposite directions.

[0010] In this scheme, after the support seat is deflected, the support seat drives the support ring to slide in the fixed sleeve through the moving rod. When the support seat is deflected in place, the fixed sleeve and the support ring are locked by the positioning pin, and the guide seat is locked by the latch. At this time, when drilling, the support rod is subjected to the shear force transmitted by the support seat, and the moving rod converts the shear force into a driving force on the slide seat through the connecting rod and squeezes the limit rod. When the shear force reaches a certain level, the squeezing force on the limit rod exceeds the elastic force of the elastic reset member, and the limit rod slides into the groove, thereby causing the slide seat to slide in the slide groove, prompting the moving rod to move relative to the support ring, releasing the shear force received, and preventing the moving rod from breaking and affecting safety. When the slide seat slides to the adjacent limit hole facing the limit rod, the limit rod slides into the limit hole under the action of the elastic reset member to restore the fixation of the moving rod. At the same time, when one of the limit rods moves, the remaining limit rods move synchronously through the cooperation of the synchronization rod, the support sleeve, and the transmission rod, that is, all slide seats are locked and released at the same time.

[0011] Furthermore, an arc block cocentric with the rotating shaft is fixed on the bracket, and an arc groove cocentric with the rotating shaft is opened on the arc block. Sliding rods are fixed at both ends of the connecting frame, and the sliding rods extend into the corresponding arc grooves and are slidably connected thereto.

[0012] Furthermore, an oblique support rod is provided between the arc block and the bracket.

[0013] Furthermore, the end surfaces of the abutting blocks are all provided with rubber cushion layers.

[0014] Furthermore, the arc block is provided with an angle mark.

[0015] Other advantages, objectives and features of the present invention will be described in the following description and will be apparent to those skilled in the art to some extent, or those skilled in the art may be taught from the practice of the present invention. The objectives and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In this solution, the gearbox housing is placed on the mounting seat 9, and the threaded rod 11 is rotated forward. The threaded rod 11 drives the clamping seat 10 to move toward the housing until the clamping seat 10 abuts against the housing. The housing is clamped and fixed in multiple directions by using multiple clamping seats 10 to improve the clamping stability of the housing. Then, the housing is driven to move to the bottom of the drilling equipment 12 by the sliding base 3 to perform drilling operations. When the drilling angle needs to be adjusted, the support seat 7 is deflected by the rotating shaft 14, and the support seat 7 drives the guide seat 8 to move through the support rod. Then, the latch is installed and the support rod is locked to support the support seat 7, so as to adjust the inclination angle of the housing, and then adjust the drilling angle. In addition, the position of the housing can be adjusted by sliding the base 3 and rotating the mounting seat 9, so that the housing can be adjusted in all directions to cooperate with drilling operations of different specifications.

[0026] In this embodiment, the clamping seat 10 is provided with a clamping portion extending upward from the slide groove, and the clamping portion includes a plurality of clamping blocks 13, the top of each of the clamping blocks 13 is fixed with a rotating shaft 14, and the bottom of each of the clamping blocks 13 is rotatably connected to an adjacent rotating shaft 14, wherein the clamping blocks 13 located at the bottom are fixedly connected to the clamping seat 10; the end surfaces of the clamping blocks 13 away from the axis of the mounting seat 9 are hinged with support rods 15, and connecting seats 18 are provided between adjacent clamping blocks 13, and the support rods 15 are hinged with adjacent connecting seats 18; positioning rods 16 perpendicular to the rotating shaft 14 are fixed to the rotating shaft 14, and annular blocks 17 are rotatably connected to the connecting seats 18, and the annular blocks 17 are threadedly connected to the corresponding positioning rods 16.

[0029] When the support seat 7 is deflected, the support seat 7 drives the support ring 20 to slide in the fixed sleeve 19 through the moving rod 21. When the support seat 7 is deflected into place, the fixing sleeve 19 and the support ring 20 are locked by the positioning pin, and the guide seat 8 is locked by the latch; at this time, when drilling is carried out, the support rod is subjected to the shear force transmitted by the support seat 7, and the moving rod 21 converts the shear force into a driving force on the slide seat 22 through the connecting rod and squeezes the limit rod 23.
