Description

Technical Field

[0001] The invention belongs to the field of machining, and in particular relates to a ball clamping mechanism and a ball drilling device. Background Art

[0002] At present, the drilling process for ball holes generally involves placing the ball holes on a ball limit table on the base of the drilling rig for limiting the position, and then drilling through the drill bit, as shown in the patent CN201710711725.5 new mechanical drilling machine. This method requires manual loading and unloading of the ball holes, which greatly affects the processing efficiency. In addition, the fixing method of the ball holes is not stable enough, and there are certain safety hazards. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a ball clamping mechanism and a ball drilling device with high efficiency, stability and reliability.

[0004] The present invention provides a ball clamping mechanism, comprising a clamping assembly and a ball supporting assembly. The ball supporting assembly is arranged opposite to the outlet of the ball feeding mechanism, and is used to receive the balls dropped from the outlet of the ball feeding mechanism. The clamping assembly comprises two movable plates that move relative to each other, a positioning pressure sleeve arranged on opposite sides of the two movable plates, and a movable plate driving member that drives the movable plates to move. The movable plate driving member drives the two movable plates to move relative to each other, thereby driving the two positioning pressure sleeves to clamp the two sides of the ball.

[0005] The ball clamping mechanism also includes a material return assembly, which includes a baffle plate arranged on the outlet of the ball feeding mechanism and a baffle plate moving member driving the baffle plate to move horizontally on the outlet plane of the ball feeding mechanism.

[0006] The ball clamping mechanism also includes a ball discharging hopper, which is arranged below the ball supporting assembly.

[0007] Furthermore, the bead supporting assembly includes a supporting block and a supporting block moving member that drives the supporting block to move toward the outlet of the bead feeding mechanism. The supporting block moving member is arranged below the bead discharge hopper, and the output shaft of the supporting block moving member passes through the bead discharge hopper.

[0008] Furthermore, the two movable plates are slidably arranged on the frame, and the two movable plates are provided with guide blocks protruding toward one side. The movable plate driving component includes a clamping spring connecting the two movable plates, a driving block slidably arranged on the frame, and a wedge block cooperating with the guide block is arranged at one end of the driving block.

[0009] Furthermore, the ball feeding mechanism outlet, the ball supporting assembly and the positioning sleeve can be arranged in multiple groups accordingly.

[0010] The present invention also provides a ball drilling device, comprising a ball feeding mechanism, a ball drilling mechanism and a ball clamping mechanism, wherein a positioning through hole penetrating a positioning sleeve is arranged on a movable plate of the ball clamping mechanism, and a drill bit of the ball drilling mechanism moves toward the positioning through hole.

[0011] The beneficial effect of the present invention is that the ball clamping mechanism provided by the present invention can clamp and fix the ball after the ball feeding mechanism drops the ball to the ball supporting assembly and before the ball rolls off the ball supporting assembly by relatively approaching two sets of positioning sleeves. During the clamping process, the position of the ball will be readjusted for self-positioning. After clamping, the ball will be stably and reliably limited, thereby facilitating other processing of the ball. When the processing is completed, it is only necessary to drive at least one of the two movable plates relatively away and wait for the ball to roll off the ball supporting assembly to complete the unloading. That is, the ball clamping mechanism can realize feeding clamping and loosening unloading, and the whole process is quick and stable, and the mechanism structure is simple, stable and reliable.

For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, a physical connection, or a wireless communication connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0025] As attached Figure 1-7 As shown, the present invention provides a ball clamping mechanism, including a clamping assembly 211 and a ball supporting assembly 212. The ball supporting assembly 212 is arranged opposite to the outlet of the ball feeding mechanism 22, and is used to receive the round balls 3 dropped from the outlet of the ball feeding mechanism 22. The clamping assembly 211 includes two relatively movable plates 2111, a positioning sleeve 2112 arranged on opposite sides of the two movable plates 2111, and a movable plate driving member 2113 for driving the movable plates 2111 to move. The movable plate driving member 2113 drives the two movable plates 2111 to move relative to each other, thereby driving the two positioning sleeves 2112 to clamp the two sides of the round balls 3.

[0026] The ball clamping mechanism provided by the present invention can clamp and fix the ball 3 by relatively bringing the two sets of positioning sleeves 2112 together after the ball 3 drops to the ball supporting assembly 212 from the ball feeding mechanism 22 and before the ball 3 rolls off the ball supporting assembly 212. During the clamping process, the position of the ball 3 will be readjusted for self-positioning. After clamping, the ball 3 will be stably and reliably limited, thereby facilitating other processing of the ball 3. When the processing is completed, it is only necessary to drive at least one of the two movable plates 2111 relatively away and wait for the ball 3 to roll off the ball supporting assembly 212 to complete the unloading. That is, the present ball clamping mechanism can realize feeding clamping and loosening unloading, and the whole process is quick and stable, and the mechanism structure is simple, stable and reliable.

[0027] The present invention also includes a material return component 224, which includes a baffle 2241 arranged on the outlet of the ball feeding mechanism 22 and a baffle moving member 2242 for driving the baffle 2241 to move horizontally in the outlet plane of the ball feeding mechanism 22. By setting the material return component 224, the ball feeding mechanism 22 can only drop one ball 3 at a time. In this embodiment, a plurality of balls 3 are retained in the barrel 222 of the ball feeding mechanism 22. When the ball 3 at the end abuts against the ball supporting component 212, the upper ball 3 abuts against the ball supporting component 212. 3 provides a certain pressure, and the two relatively close positioning sleeves 2112 assist to prevent the ball 3 from rolling off the ball supporting assembly 212. After the two positioning sleeves 2112 clamp the ball 3, the baffle moving member 2242 drives the baffle 2241 to horizontally block the opening of the barrel 222. At this time, the upper ball 3 is separated from the clamped ball 3. After the ball 3 is processed, the positioning sleeve 2112 releases the ball 3. Since there is no ball 3 above to apply pressure to the processed ball 3 at this time, the ball 3 will fall from the ball supporting assembly 212 to the next station.

[0028] In one of the preferred embodiments, the distance from the axis of the positioning sleeve 2112 to the working surface of the ball supporting assembly 212 is greater than the radius of the ball 3. When the ball 3 falls from the barrel 222 of the ball feeding mechanism 22 to the working surface of the ball supporting assembly 212, when the two positioning sleeves 2112 are relatively close to clamp the ball 3, the bottom of the ball 3 will be separated from the working surface of the ball supporting assembly 212 by self-positioning. After the ball 3 is processed, the positioning sleeve 2112 is relatively far away to release the ball 3, and the ball 3 falls to the working surface of the ball supporting assembly 212 at a certain height. The ball 3 will roll from the working surface of the ball supporting assembly 212 to the next workstation by inertia, thereby effectively improving the stability of the ball 3 before clamping and the success rate of the ball 3 falling after being released.

[0029] In one embodiment, the present invention further comprises a ball discharge hopper 213, which is arranged below the ball supporting assembly 212, so as to facilitate the direct collection or transportation of the processed balls 3 to the next workstation.

[0030] In one embodiment, the bead supporting assembly 212 includes a supporting block 2121 and a supporting block moving member 2122 driving the supporting block 2121 to move toward the outlet of the ball feeding mechanism 22. The supporting block moving member 2122 is arranged below the ball discharge hopper 213, and the output shaft of the supporting block moving member 2122 passes through the ball discharge hopper 213. In this embodiment, the working surface supporting block 2121 of the bead supporting assembly 212 can adjust the distance from the outlet of the ball feeding mechanism 22, so that the process of supporting the balls 3 to be processed and unloading the processed balls 3 can be faster and more reliable, further improving the efficiency and stability of clamping and unloading. At the same time, when the balls 3 fall from the supporting block 2121, they directly fall into the ball discharge hopper 213 for collection or transportation to the next workstation, ensuring the unloading efficiency.

[0031] In one embodiment, if Figure 3-5 As shown, the two movable plates 2111 are slidably arranged on the frame 25, and the two movable plates 2111 are provided with a guide block 21111 protruding toward one side. The movable plate driving member 2113 includes a clamping spring 21131 connecting the two movable plates 2111, and a driving block 21132 slidably arranged on the frame 25, and one end of the driving block 21132 is provided with a wedge block 21133 cooperating with the guide block 21111. In this embodiment, the two movable plates 2111 always maintain a relatively close clamping state through the contraction force of the clamping spring 21131. Only after the driving block 21132 drives the wedge block 21133 to insert into the two guide blocks 21111 through the driving force of linear movement, the wedge block 21133 gradually opens the two guide blocks 21111, thereby driving the two movable plates 111 to move relatively away from each other and switch to a loose state. After the driving force of the linear movement of the driving block 21132 is unloaded, the clamping spring 21131 drives the two movable plates 2111 to move relatively close, and the two guide blocks 21111 push the wedge block 21133 back to its original position. This driving method can ensure that the clamping force of the movable plate 2111 will not be too large, and can avoid damage to the ball 3 to a certain extent.

[0032] The outlet of the ball feeding mechanism 22, the ball supporting assembly 212 and the positioning sleeve 2112 can be arranged in multiple groups accordingly, and then a group of movable plate driving parts 2113 can be used to achieve simultaneous clamping of multiple balls 3, thereby improving work efficiency without increasing the driving structure.

[0033] The present invention also provides a ball drilling device, including a ball feeding mechanism 22, a ball drilling mechanism 23 and a ball clamping mechanism 21. The movable plate 2111 of the ball clamping mechanism 21 is provided with a positioning through hole 2114 that penetrates the positioning sleeve 2112. The drill bit of the ball drilling mechanism 23 is moved toward the positioning through hole 2114. In this embodiment, after the ball clamping mechanism 21 clamps the ball 3, the positioning through hole 2114 on the movable plate 2111 is used as a drilling reference to accurately drill the ball 3. At the same time, the setting position of the ball drilling mechanism 23 at this time will not affect the clamping and unloading of the ball 3 by the ball clamping mechanism 21 at all. In addition, the drill bit drills the ball 3 from the inside of the positioning sleeve 2112. At this time, only a cooling water mechanism needs to be added in the positioning sleeve 2112 to accurately and quickly achieve cooling, which is convenient for adding a cooling mechanism to the drill bit.

[0034] Among them, the ball feeding mechanism 22 includes a material tray 221 and a barrel 222 connected to the material tray 221. The baffle 2241 of the material return assembly 224 is arranged at the outlet of the barrel 222. This arrangement is convenient for continuously conveying the balls 3 for processing. Preferably, a rotatable mixing plate 223 is arranged on the material tray 221 to drive the balls 3 in the material tray 221 to roll into the barrel 222, while preventing the balls 3 in the material tray 221 from blocking the entrance of the barrel 222.

[0035] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
