Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to an auxiliary automatic feeding structure. Background Technology

[0002] In existing machine tool processing, the workpiece needs to be clamped in the chuck first, and then the cutting head is driven to move closer to the workpiece so that the cutting head can perform machining on the workpiece. However, when clamping small workpieces, due to their small size, they are prone to slipping during manual clamping, which can cause injury to workers and poses a safety hazard. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an auxiliary automatic feeding structure that facilitates the movement of workpieces to the clamping position, assists in feeding, prevents workpiece slippage, avoids safety hazards, and protects the safety of workers.

[0004] The technical solution adopted in this utility model is as follows:

[0005] An auxiliary automatic feeding structure includes a mounting base for mounting on a slide table. A feeding seat is mounted on one side of the mounting base via at least one guide shaft. A return spring is sleeved on the guide shaft. The feeding seat has a feeding through hole, which is connected to a pressing through hole. The pressing through hole is fitted with a pressing rod for positioning the workpiece in the feeding channel. The pressing rod is connected to a lifting driver.

[0006] Preferably, the pressing through hole is located at the top of the feeding seat, and the lifting drive is installed above the feeding seat.

[0007] More preferably, the lifting actuator is a cylinder.

[0008] Preferably, a first mounting groove for accommodating one end of a reset spring is provided on one side of the feeding seat, and the first mounting groove is connected to a first shaft hole. A second mounting groove for accommodating the other end of the reset spring is provided on one side of the mounting seat, corresponding to the position of the first mounting hole, and the second mounting groove is connected to a second shaft hole. The guide shaft passes through the second shaft hole, the second mounting groove, and the first mounting groove and is aligned with the first shaft hole.

[0009] Preferably, the guide shaft is a pin, and the end of the pin is fitted with a nut located on the other side of the mounting base.

[0010] Preferably, the mounting base is provided with a feeding channel that connects to the feeding through hole, and the feeding channel is connected to an opening at the top of the mounting base that communicates with the feeding channel. The cross-section of the feeding channel is U-shaped.

[0011] Preferably, the bottom of the mounting base is bolted to a base, the mounting base has an upper connecting hole, the base has a lower connecting hole corresponding to the upper connecting hole, and the base also has at least two mounting holes that mate with the bolts. The mounting base is mounted on the slide table via the base.

[0012] Preferably, one side of the mounting base is also provided with a support seat for supporting and loading materials, the support seat being below the loading base and the base being below the support seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides an auxiliary automatic feeding structure. After the workpiece is transported to the feeding through hole, the pressing rod is driven to descend by the lifting driver. The pressing rod presses on the workpiece until the workpiece moves to the clamping head of the machine tool. After the clamping head clamps the workpiece, the lifting driver drives the pressing rod to rise and release the workpiece. This facilitates the movement of the workpiece to the clamping position, assists in feeding, prevents the workpiece from sliding, avoids safety hazards, and protects the safety of the workers.

[0018] The preferred embodiments of this utility model will be described in detail with reference to the accompanying drawings.

[0019] Figures 1 to 3 This is a preferred embodiment of an auxiliary automatic feeding structure provided by this utility model. For example... Figures 1 to 3As shown, the auxiliary automatic feeding structure includes a mounting base 10 for mounting on a slide table. A feeding seat 20 is mounted on one side of the mounting base 10 via at least one guide shaft 30. A return spring 40 is sleeved on the guide shaft 30. The feeding seat 20 has a feeding through hole 21, which connects to a pressing through hole 22. The pressing through hole 22 is fitted with a pressing rod 51 for positioning the workpiece in the feeding channel. The pressing rod 51 is connected to a lifting driver 50. After the workpiece is conveyed to the feeding through hole 21, the lifting driver 50 drives the pressing rod 51 to descend, pressing the workpiece. To prevent the workpiece from falling off, when the slide table moves the loading seat 20 to the machine tool's mounting chuck position, the guide shaft 30 and return spring 40 between the loading seat 20 and the mounting seat 10 act as a buffer to prevent the loading seat 20 and the workpiece from colliding. After the machine tool's mounting chuck clamps the workpiece extending out of the loading through hole 21, the lifting driver 50 drives the pressing rod 51 to rise, releasing the workpiece. The slide table then moves the loading seat 20 away from the machine tool's mounting chuck position. This assists in loading the workpiece, prevents it from sliding, avoids safety hazards, and protects the safety of the workers.

[0020] The pressing through hole 22 is located on the top of the loading seat 20, and the lifting driver 50 is installed above the loading seat 20. The lifting driver 50 is a cylinder.

[0021] like Figure 3 and Figure 4 As shown, the loading seat 20 has a first mounting groove 23 on one side for accommodating one end of the return spring. The first mounting groove is connected to a first shaft hole 24. The mounting base 10 has a second mounting groove 11 on one side, corresponding to the first mounting hole, for accommodating the other end of the return spring. The second mounting groove 11 is connected to a second shaft hole 12, which is a through hole. The guide shaft 30 passes through the second shaft hole 12, the second mounting groove 11, and the first mounting groove 23, and is aligned with the first shaft hole 24. A space is left between the end of the guide shaft 30 and the first shaft hole 24, so that when the loading seat 20 contacts the mounting chuck of the machine tool, the loading seat 20 can be squeezed backward, squeezing the return spring and preventing damage to the loading seat 20 and the workpiece. The guide shaft 30 is a pin, and the end of the pin is fitted with a nut on the other side of the mounting base 10.

[0022] The mounting base 10 is provided with a feeding channel 13 that connects with the feeding through hole; the top of the mounting base is provided with an opening 14 that communicates with the feeding channel, and the cross-section of the feeding channel 13 is U-shaped; to facilitate the input of workpieces from the outside into the feeding through hole 21.

[0023] like Figure 3As shown, the bottom of the mounting base 10 is bolted to a base 15. The mounting base 10 has an upper connecting hole 16, and the base 15 has a lower connecting hole 151 corresponding to the upper connecting hole 16. The base 15 also has at least two mounting holes 152 that mate with the bolts. The base 15 is then bolted onto the slide. The upper connecting hole 16 and the lower connecting hole 151 of the mounting base 10 are aligned, and the mounting base 10 is then bolted to the base 15. Thus, the mounting base 10 is mounted on the slide via the base 15. The base 15 has a boss 153, and the bottom of the mounting base 10 has a groove 18 corresponding to the boss 153. The mounting holes 152 and the lower connecting holes 151 are distributed on the boss 153.

[0024] The mounting base 10 is also provided with a support base 17 for supporting and loading materials on one side. The support base 17 is located below the loading base 20, and the base 15 is located below the support base 17.

[0025] In summary, the technical solution of this utility model can fully and effectively achieve the aforementioned objectives. Furthermore, the structure and functional principles of this utility model have been fully verified in the embodiments, achieving the expected effects and objectives. Without departing from the principles and essence of this utility model, various changes or modifications can be made to the embodiments.
