[0026] Embodiment 1

[0027] In order to solve the technical problems in the background technology, the following workpiece ejector hole processing equipment is provided:

[0028] Combination Figure 1 As shown, the workpiece ejector hole processing equipment includes:

[0029] A handle 1 is vertically arranged and generally C-shaped, with a threaded hole 14 extending through the top and a waste hole 13 extending through the bottom, and the waste hole 13 is coaxially arranged with the threaded hole 14;

A universal bolt 42 is transversely threaded in the locking hole seat 41, and the central axis of the universal bolt 42 is perpendicular to the central axis of the waste hole 13 in space.

[0033] By adopting the above technical scheme, the processing equipment is divided into two parts, one part is a special integrated handle 1 and the guide mechanism 3 and the clamping mechanism 4 arranged thereon, and the other part is a workpiece ejector hole drilling process performed by the drill bit 25 at the end of the rotating handle 21 inserted into the threaded hole 14 at the top of the handle 1, so as to realize the rapid drilling of the workpiece on the front line, thereby ensuring the effective operation of the equipment installation and commissioning, and will not affect the assembly and maintenance period due to the misaligned workpiece. It is safe and efficient, can improve the efficiency of on-site drilling, save time and cost, eliminate the safety hazards of existing electric drilling operations, meet the temporary needs of drilling workpieces in narrow spaces, and is simple to operate, does not require a large amount of manpower participation, reduces labor costs, and ensures economic benefits. It is also reasonably and simply designed, easy to maintain, and reduces the cost of later use.

[0034] Embodiment 2

[0035] Combination Figure 2 , Figure 3 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0036] In this embodiment, the bottom side surfaces of the handle 1 are symmetrically provided with receiving grooves 12, and the inner ends of the two receiving grooves 12 facing away from the clamping mechanism 4 are vertically and symmetrically provided with leg 5 rods 15, and the leg 5 rods 15 are pivotally sleeved with a leg 5 that is compatible with the receiving grooves 12, and the leg 5 rotates outward with the leg 5 rod 15 as the center of the circle, and a square protrusion is vertically integrated on the bottom surface of the end of the leg 5, and the protrusion is gap-engaged with a groove 121 arranged on the bottom edge of the corresponding receiving groove 12.

[0037] The middle side of the handle 1 is symmetrically provided with hollow grooves 11 , and a plurality of through holes are arranged between two of the hollow grooves 11 .

[0038] By adopting the above technical scheme, the handle 1 is of one-piece design, and a symmetrical hollow groove 11 is opened on its side. The several through holes arranged in the hollow groove 11 can not only avoid stress concentration, but also reduce weight and facilitate carrying. The above structural design ensures the overall strength while also ensuring the high precision and high stability of the drilling operation; the protrusions of the two side legs 5 in the storage groove 12 can form a stable triangular structure with the handle 1 when unfolded, thereby enhancing the accuracy of the drilling operation, and can be folded back into the storage groove 12 when not in use, which is convenient for transportation and does not take up space, effectively reducing the decline in drilling accuracy in the later stage, reducing safety risks, and reducing later maintenance costs.

[0039] Embodiment 3

[0040] Combination Figure 2 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0041] In this embodiment, the guide mechanism 3 includes

[0042] A guide bracket 31, which is detachably connected to the inner side surface of the middle part of the handle 1 in a vertical manner;

[0043] A stabilizing sleeve 32, which is integrally and vertically arranged at the outer end of the guide bracket 31;

[0044] A fixing sleeve 33 is detachably connected to the stabilizing sleeve 32 in radial direction. The fixing sleeve 33 and the stabilizing sleeve 32 have the same shape and are connected to form a square inner tube.

[0045] A guide bushing 24 is nested in the square inner tube and has a circular hole therein, which is interlocked with the screw rod 22 in a clearance manner.

[0046] By adopting the above technical scheme, in the long-term use of drilling operations, the guide mechanism 3 helps the drilling mechanism 2 to drill stably and efficiently, effectively improving the service life and drilling fault tolerance of the processing equipment, adding a layer of insurance for the drilling operation, reducing safety risks, and improving economic benefits. The design is reasonable and simple, which is conducive to maintenance and reduces the cost of later use.

[0047] Embodiment 4

[0048] Combination Figure 2 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0049] In this embodiment, spherical handles 212 are axially symmetrically provided at both ends of the rotating handle 21 .

[0050] The outer axial surface of the screw rod 22 is covered with a dust cover 23 , and the dust cover 23 is located between the guide bushing 24 and the threaded hole 14 . The dust cover 23 is elastic and can be extended and retracted up and down along with the screw rod 22 .

[0051] By adopting the above technical scheme, the spherical handles 212 arranged at both ends of the handle in the drilling mechanism 2 not only improve the gripping feeling of rotation, but also reduce the possibility of rotation and slipping out of the hand during drilling, reduce accidental losses, and improve the safety factor; and the elastic dust cover 23 sleeved on the outer axial surface of the screw 22 synchronously expands and contracts up and down with the rotation of the screw 22, effectively preventing dust from adhering to the screw 22, ensuring the stability of the drilling mechanism 2 in long-term use, reducing the decrease in accuracy caused by impurities wearing the screw 22, directly extending the service life, and reducing safety risks.

[0052] The working principle and use process of this utility model:

[0053] When the workpiece ejector hole processing equipment of the utility model is implemented, the frame legs 5 in the receiving grooves 12 on both sides of the handle 1 are first unfolded to form a triangle with the handle 1 body and then the universal bolts 42 in the locking hole seat 41 are adjusted to accurately clamp the workpiece to be processed, and then the ball handles 212 at both ends of the rotating handle 21 are held. While the screw 22 is rotated, the drill bit 25 at the end of the screw 22 is fed downward, and the dust cover 23 sleeved on the outer peripheral surface of the middle part of the screw 22 is extended and retracted accordingly. The screw 22 rotates and feeds stably through the guide bushing 24 in the stabilizing sleeve 32 to ensure the coaxial feed of the drilling operation until the drill bit 25 penetrates the workpiece and finally reaches the waste hole 13 to complete the drilling operation.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
