Description

Technical Field

[0001] This utility model belongs to the technical field of drill body processing equipment, and relates to a feeding mechanism for a drill body drilling equipment. Background Technology

[0002] Drill chucks are a key accessory in the power tool and machine tool industries, widely used in electric drills and drilling machines. Existing drill chucks generally consist of a drill body with a connecting hole at the rear end for mates with the motor shaft. At the front end of the drill body, three jaw holes are evenly arranged circumferentially, inclined towards the centerline of the drill body. These jaw holes have the same inclination angle and contain jaws that can slide back and forth within them. The rear end of each jaw is threaded. The drill chuck includes a nut that surrounds the drill body and is axially constrained, with the nut threadedly connected to the jaws. Currently, the drill chuck needs to be engaged with a robot arm via a quick-release mechanism. Therefore, multiple circular holes need to be drilled on the outer circumference of the rear end of the drill body to ensure stable engagement with the drill body when the steel balls in the quick-release mechanism move radially inward. This requires drilling equipment to machine these circular holes.

[0003] The applicant previously developed a jaw hole processing device for a drill chuck with application number CN202311867754.2, which includes a frame, a positioning mechanism, a drilling mechanism, a material handling mechanism, and a loading mechanism and a unloading mechanism arranged side by side. A turntable is rotatably connected to the middle of the frame. There are several positioning mechanisms that are evenly distributed around the turntable. The number of drilling mechanisms is one less than that of the positioning mechanisms and they are evenly distributed around the turntable along with the material handling mechanism. The positioning mechanism includes a positioning screw and a driving component one that drives the positioning screw to rotate. The material handling mechanism includes two clamps arranged side by side, a driving component two that drives the two clamps to rotate, a driving component three that drives the two clamps to move back and forth between the loading / unloading mechanism and the positioning mechanism, and a driving component four that drives the two clamps to move along the distribution direction.

[0004] The above-mentioned processing equipment can drill holes in the drill body, but there are still shortcomings: the drill body needs to open multiple radial holes in the circumference, so the drill body sent out by the feeding track needs to be adjusted to an upright state before being sent to drill, and the receiving seat needs to bear the function of blocking the material so that the drill body on it does not have enough space to achieve smooth reversal. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing a feeding mechanism for a drilling equipment. The technical problem this utility model aims to solve is: how to ensure that each drill body is fed individually and facilitate smooth reversal of the drill body.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A feeding mechanism for a drilling machine includes a frame. The feeding mechanism includes a feeding track, a feeding seat, a receiving seat, and a cutting cylinder fixed to the frame. The feeding seat includes two vertically shaped, parallel, and opposite clamping plates. One end of the feeding track is fixed downwards to the feeding seat and allows the drill bit to fall between the two clamping plates. The receiving seat has a strip-shaped receiving groove on its upper side, directly opposite the two clamping plates, for accommodating the drill bit. The cutting cylinder is horizontally positioned, with its output end facing the outer side of the clamping plates. The feeding mechanism is characterized by further including a square-shaped baffle frame, which is sleeved around the two clamping plates, and one side of the baffle frame is fixedly connected to the output end of the cutting cylinder. Each of the two sides of the baffle frame along the setting direction of the cutting cylinder is fixedly provided with a baffle plate extending horizontally toward the inside of the baffle frame. The two baffle plates are spaced apart vertically, and both baffle plates pass through the clamping plates and can extend into and out of the space between the two clamping plates under the drive of the cutting cylinder. There is a gap between the lower side of the clamping plate and the upper side of the receiving seat.

[0008] The feeding track transports the horizontal drill body from the outside downwards to the frame. The two clamping plates cooperate with the lower end of the feeding track to ensure smooth connection of the drill body. The strip-shaped receiving hole on the upper side of the receiving seat positions and stabilizes the falling drill body. A square-shaped baffle is fitted around the two clamping plates, with its sides fixed to the output end of the cutting cylinder. Inwardly extending baffle plates are fixed on opposite sides of the baffle, ensuring the vertical spacing between the two baffle plates matches the outer diameter of the drill body. This guarantees that only one drill body can be accommodated between the two baffle plates. During the reciprocating movement of the cutting cylinder, when the higher baffle plate disengages from the space between the two clamping plates, the upper drill body is no longer obstructed and can fall. At this point, the lower baffle plate extends into the space between the two clamping plates. In between, the falling drill body is caught, and then the cutting cylinder is activated again. The lower baffle plate disengages, allowing the drill body to fall into the receiving groove below. At the same time, the higher baffle plate extends between the two clamping plates to block the falling drill body above, ensuring that the drill bodies can be fed to the receiving seat one by one without interfering with each other. Meanwhile, the receiving seat does not have to bear the function of blocking material, so that there can be a gap between the lower side of the clamping plate and the receiving seat. This can prevent interference with the upper part when the drill body is adjusted to an upright position and the end is tilted. The feeding of the drill body one by one also facilitates the smooth reversal of the drill body, making the feeding smooth and stable.

[0009] In the feeding mechanism of the aforementioned drilling equipment, the inner side of the baffle plate has two horizontal fork arms facing the inside of the baffle frame, and the fork arms slide through the clamping plate. The middle part of the drill body has a protruding shoulder, which facilitates the two fork arms to support the two ends of the drill body respectively, provides clearance for the shoulder in the middle, avoids the shoulder being pressured alone, and makes the support of the baffle plate more stable.

[0010] In the feeding mechanism of the aforementioned drilling equipment, both clamping plates have positioning holes at positions opposite to the baffle plates along the setting direction of the cutting cylinder. When the cutting cylinder drives the baffle frame to move horizontally, the baffle plates can be simultaneously inserted into the positioning holes of the two clamping plates. Thus, when the higher, lower baffle plate carries the drill body above, the baffle plate can be supported by both clamping plates simultaneously, effectively preventing the baffle plate from easily deforming due to the downward pressure of the drill body and ensuring feeding stability.

[0011] In the feeding mechanism of the aforementioned drilling equipment, a pushing cylinder and a reversing seat are fixedly connected to the receiving seat. The pushing cylinder is horizontally positioned, and its output end is opposite to one end of the receiving groove. The reversing seat has an arc-shaped reversing channel with a circular cross-section. The upper end of the reversing channel is horizontally positioned and connected to the other end of the receiving groove, while the lower end of the reversing channel is vertically downward. Thus, the drill body falling into the receiving groove can slide one end into the reversing channel under the pushing action of the pushing cylinder, and gradually turn to an upright position along the reversing channel under its own weight, finally exiting from the lower end of the reversing channel to achieve upright feeding.

[0012] In the feeding mechanism of the aforementioned drilling equipment, the feeding base further includes two strip-shaped connecting arms. The outer sides of the two clamping plates are respectively fixed to the receiving base and the cutting cylinder via the two connecting arms. This helps to ensure the stability of the gap between the clamping plates and the receiving base, while keeping the position of the cutting cylinder relative to the clamping plates stable and maintaining precise driving.

[0013] In the feeding mechanism of the aforementioned drilling equipment, the lower end of the feeding track and the upper sides of the two clamping plates each have several spaced vertical toothed blocks. The feeding track and the two clamping plates are fixed together by the engagement of these vertical toothed blocks. This allows the lower end of the feeding track to form a more stable connection with the clamping plates through the vertical toothed blocks, ensuring structural stability.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] The feeding mechanism of this drilling equipment has two spaced baffles on a square baffle plate, which allows for a certain gap between the lower side of the clamping plate and the receiving seat. This helps to avoid interference with the upper components when the drill body is adjusted to an upright position and the end tilts up. This allows for the feeding of drill bodies one by one, while also facilitating smooth reversal of the drill body, making the feeding smooth and stable. Attached Figure Description

Detailed Implementation

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figure 1-5As shown, this drilling equipment includes a disc-shaped frame 1. The feeding mechanism includes a feeding rail 2, a feeding seat 3, a receiving seat 4, and a cutting cylinder 5 fixed on the frame 1. The feeding seat 3 includes two vertically shaped, parallel, and opposite clamping plates 31. One end of the feeding rail 2 is fixed downwards on the feeding seat 3, allowing the drill body 12 to fall between the two clamping plates 31. The upper side of the receiving seat 4 has a strip-shaped receiving groove 41 for accommodating the drill body 12, located directly opposite the two clamping plates 31. The cutting cylinder 5 is horizontally arranged, with its output end aligned with the outer side of the clamping plate 31. The vertical feeding mechanism also includes a square-shaped baffle 6, which is fitted around the two clamping plates 31. One side of the baffle 6 is fixed to the output end of the cutting cylinder 5. On each of the two opposite sides of the baffle 6 along the direction of the cutting cylinder 5, there is a baffle plate 7 extending horizontally inward. The two baffle plates 7 are spaced apart vertically and pass through the clamping plates 31, allowing them to extend into and out of the space between the clamping plates 31 under the drive of the cutting cylinder 5. A gap 8 is left between the lower side of the clamping plate 31 and the upper side of the receiving seat 4. The inner side of the baffle plate 7 has two horizontal fork arms 71 extending inward towards the baffle 6, which slide through the clamping plate 31. Both clamping plates 31 have positioning holes 311 at positions opposite to the baffle plate 7 along the setting direction of the cutting cylinder 5. When the cutting cylinder 5 drives the baffle frame 6 to move horizontally, the baffle plate 7 can be simultaneously inserted into the positioning holes 311 of the two clamping plates 31. The receiving seat 4 is fixedly connected to a pushing cylinder 9 and a reversing seat 10. The pushing cylinder 9 is horizontally set and its output end is opposite to one end of the receiving groove 41. The reversing seat 10 has an arc-shaped reversing channel 101 with a circular cross-section. The upper end of the reversing channel 101 is horizontally set and connects to the other end of the receiving groove 41. The lower end of the reversing channel 101 is vertically downward. The feeding seat 3 also includes two strip-shaped connecting arms 32. The outer sides of the two clamping plates 31 are fixedly connected to the receiving seat 4 and the cutting cylinder 5 through the two connecting arms 32, respectively. The lower end of the feeding track 2 and the upper side of the two clamping plates 31 are each provided with a number of vertical toothed blocks 11 arranged at intervals. The feeding track 2 and the two clamping plates 31 are fixed by the engagement of the vertical toothed blocks 11.

[0024] During processing, the feeding track 2 continuously conveys the horizontally placed drill body 12 upwards. The drill body 12 enters between the two clamping plates 31 and is limited by the baffle plate 7. The cutting cylinder 5 moves reciprocally. When the higher baffle plate 7 disengages from the space between the two clamping plates 31, the upper drill body 12 is no longer obstructed by the baffle plate 7 and can fall. At this time, because the lower baffle plate 7 extends between the two clamping plates 31, it catches the falling drill body 12. Then, the cutting cylinder 5 actuates again. The lower baffle plate 7 can disengage to allow the drill body 12 to fall into the lower receiving groove 41, while the higher baffle plate 7 extends between the two clamping plates 31 to block the upper drill body 12 from falling, thus achieving feeding one by one. After the drill body 12 falls into the lower receiving groove 41, the pushing cylinder 9 can push the end of the drill body 12 so that the other end is inserted into the reversing channel 101. Then the drill body 12 can slide down along the reversing channel 101 and be adjusted to an upright state, thus achieving upright feeding.
