Description

Technical Field

[0001] This utility model relates to the field of automotive sleeve processing equipment, and in particular to a semi-automatic double-head drilling machine for automotive sleeves. Background Technology

[0002] The automotive socket has a cylindrical structure. One end of the socket has a hexagonal groove that engages with a nut to loosen it. The other end of the socket has a square-headed hole with a transverse through-hole along the radial direction of the socket. The end of a pneumatic impact wrench is inserted into the square-headed hole and secured by a ball bearing in the transverse through-hole. The general structure of the automotive socket can be referenced in our previously filed patent CN201621459790 - An Open-Ended Socket for Automobiles.

[0003] In the production of automotive sleeves, after the square head hole and groove are machined, the sleeve needs to be drilled to form a transverse through hole. This transverse through hole penetrates the sleeve radially and remains connected to the square head hole. Our traditional method involves placing the automotive sleeve within the groove's support base, then using clamping mechanisms at both ends to hold the sleeve in place; the drilling machine then performs unidirectional drilling from top to bottom; after completion, the sleeve is removed, the direction is reversed, and drilling is performed on the other side. This method is inefficient.

[0004] Patent application number "202111642153.2", entitled "A Fully Automatic Double-Hole Drilling Machine and Drilling Method for Automobile Sleeves", is our company's patent. It employs a fully automatic mode to simultaneously drill transverse through holes in automobile sleeves without requiring manual feeding. This device significantly improves efficiency. However, since our company previously used small, unidirectional drilling machines, replacing them all with fully automatic double-hole drilling machines would require the purchase of new supporting equipment, which would undoubtedly increase costs considerably. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a semi-automatic double-head drilling machine for automobile sleeves. On the one hand, it retains the original drilling machine, changes the layout, and performs double-head drilling to improve efficiency; on the other hand, it adopts a semi-automatic mode to reduce the cost of purchasing equipment.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A semi-automatic double-head drilling machine for automotive sleeves includes a receiving trough, with drilling mechanisms mounted symmetrically on the left and right sides above the receiving trough, and clamping mechanisms arranged front and rear between the two drilling mechanisms to clamp the automotive sleeves. The drilling mechanism includes a drill, the drill rod of which points towards the side wall of the automobile sleeve, and the tail of the drill is connected to the output end of an electric push rod; the housing of the electric push rod is fixed to the first mounting plate. The clamping mechanism includes a positioning seat, which is fixed to the first mounting plate; a positioning square head is fixed on the positioning seat, and the positioning square head is inserted into one end of the car sleeve for positioning; a telescopic cylinder is arranged at the other end of the car sleeve, and a top plate is installed at the output end of the telescopic cylinder, and the top plate presses against the other end of the car sleeve.

[0007] A slider is fixed to the side of the drill housing, and the slider slides in cooperation with a slide rail fixed on the first mounting plate.

[0008] Water spray pipes are arranged on the left and right sides of the positioning square head, with the water outlets of the water spray pipes pointing towards the drill hole.

[0009] One end of the receiving trough is connected to a water outlet pipe, and a filter screen is installed at the water inlet end of the water outlet pipe.

[0010] The receiving trough has a waste outlet on one side near the bottom surface, and a door is installed at the waste outlet.

[0011] The door is equipped with a magnet layer on both the front and back sides. The magnet layer is distributed on the outer ring of the door end face. A rubber layer is fixed inside the inner ring of the magnet layer. The rubber layer is flush with the outer end face of the magnet layer.

[0012] A material rake is placed inside the receiving trough.

[0013] This utility model provides a semi-automatic double-head drilling machine for automotive sleeves, which has the following technical effects: 1) The existing drilling rig is utilized by changing its installation position to a symmetrical installation on both sides, and driven by an electric push rod. At the same time, a clamping mechanism with a positioning square head and a top plate clamping is used to position and clamp the car sleeve. In this way, drilling can be carried out at both ends simultaneously, improving efficiency. Moreover, compared with the fully automatic equipment in the patent application number "202111642153.2" "A Fully Automatic Double-Hole Drilling Rig and Drilling Method for Car Sleeves", this application can directly utilize the existing small drilling rig without the need to purchase new large-scale supporting equipment, thus saving on equipment purchase costs.

[0014] 2) By setting up a receiving trough, wastewater and waste residue can be collected to avoid environmental pollution; the flushing sewage can be quickly discharged using the water outlet pipe at one end; and waste can be cleaned using the waste outlet, door, chute, etc. on one side.

Detailed Implementation

[0024] like Figure 1-2 As shown, a semi-automatic double-head drilling machine for automotive sleeves includes a receiving trough 1. A first mounting plate 2 is vertically fixed to the upper end of one side of the receiving trough 1, and a second mounting plate 3 is vertically fixed to the middle of the upper end of the other side of the receiving trough 1. Drilling mechanisms 4 are arranged symmetrically on the first mounting plate 2, and a positioning seat 5 is fixed on the first mounting plate 2 between the two drilling mechanisms 4. A positioning square head 6 is fixed on the positioning seat 5. A telescopic cylinder 7 is mounted on the second mounting plate 3, and a top plate 8 is mounted on the output end of the telescopic cylinder 7, with the top plate 8 facing the positioning square head 6.

[0025] like Figure 3 As shown, the drilling mechanism 4 includes a drill rig 4.1, with the drill rod 4.1.1 pointing towards the automotive sleeve 9. A slider 4.2 is fixed to the side of the housing of the drill rig 4.1, and the slider 4.2 slides in cooperation with a slide rail 4.3 fixed on the first mounting plate 2. The tail end of the housing of the drill rig 4.1 is connected to the output end of an electric push rod 4.4, and the main body of the electric push rod 4.4 is fixed on the first mounting plate 2.

[0026] During drilling, the drill rig 4.1 starts and drives the drill rod 4.1.1 to rotate. The electric push rod 4.4 drives the drill rig 4.1 to move towards the automobile sleeve 9, thereby drilling a transverse hole in the automobile sleeve 9. By setting the slider 4.2 and the slide rail 4.3, the movement of the drill rig 4.1 can be guided.

[0027] like Figure 1 As shown, preferably, water spray pipes 10 (simplified in the figure) are arranged on the left and right sides of the positioning square head 6. The other end of the left and right water spray pipes 10 is connected to the pump body through a pipe, and the pump body is connected to the water supply source through a pipe. The water spray pipes 10 are pointed towards the drill hole to facilitate the flushing away of drill cuttings at the drill hole.

[0028] like Figure 1 As shown, preferably, one end of the receiving trough 1 is connected to a water outlet pipe 11 (simplified in the figure). The water outlet pipe 11 returns the water to the sedimentation tank for sedimentation and reuse. The water outlet pipe 11 is used to divert the water in the receiving trough 1 away. A filter screen is installed on the water outlet pipe 11 at the inner wall of the receiving trough 1 to prevent drill cuttings from being drawn out through the water outlet pipe 11.

[0029] like Figures 4-5 As shown, preferably, a waste outlet is provided at the bottom of the receiving trough 1 on one side of the second mounting plate 3. A door 12 is provided at the waste outlet, and the upper end of the door 12 is hinged to the receiving trough 1. Magnet layers 12.1 are provided on both sides of the door 12, distributed around the outer ring of the end face of the door 12. A rubber layer 12.2 is fixed to the inner ring of the end face of the door 12. By providing the magnet layers 12.1, the door 12 remains magnetically attracted and fixed to the side wall of the receiving trough 1 whether it is closed vertically downwards to the waste outlet or flipped to open vertically upwards to the waste outlet. The rubber layer provides a seal when the waste outlet is closed vertically downwards.

[0030] like Figure 4 As shown, preferably, a rake 13 is placed in the receiving trough 1. Since the automotive sleeve is made of metal, the waste chips after drilling are in the form of short, fine filaments. The rake 13 can be used to push the waste chips accumulated in the receiving trough 1 out to the waste outlet.

[0031] like Figure 4 As shown, preferably, a chute 14 is fixed at an angle downward on the waste outlet side. The material rake 13 pushes the waste from the waste outlet into the chute 14. A collection bag is arranged at the discharge end of the chute 14 for collection and unified recycling.

[0032] Preferably, magnets are embedded in the four sides of the positioning square head 6. The magnets ensure that after one end of the car sleeve 9 is inserted into the positioning square head 6, it can be attracted to the positioning square head 6 and will not fall off.

[0033] Working principle and process: 1) such as Figure 7 As shown, during operation, the operator aligns the square hole 9.2 at one end of the car sleeve 9 with the positioning square head 6 and inserts them into place; then the telescopic cylinder 7 extends, and the top plate 8 acts on the other end of the car sleeve 9, pressing the car sleeve 9 tightly against the positioning seat 5.

[0034] 2) Then, start the left and right drilling mechanisms 4. The two drills 4.1 move closer to the car sleeve 9. The drill rod 4.1.1 of the drill 4.1 rotates and drills laterally into the car sleeve 9. After the drilling is completed, the car sleeve 9 forms a transverse through hole 9.3 on both sides. Then, the electric push rod 4.4 drives the drill rod 4.1.1 of the drill 4.1 away from the car sleeve 9, and the telescopic cylinder 7 drives the top plate 8 to retract. The car sleeve 9 can then be removed manually.

[0035] During the drilling process, the water spray pipe 10 continuously sprays high-pressure water to blow drilling debris into the receiving trough 1; the water spraying stops when the drilling is finished. Wastewater flows out through the outlet pipe 11.

[0036] 3) When some drilling debris accumulates in the receiving trough 1, open the gate 12 at the waste outlet. Then, use the rake 13 to remove and collect the drilling debris.
