Description

Technical Field

[0001] This utility model relates to a receiving device for a precision machine tool, belonging to the field of machine tools. Background Technology

[0002] The receiving device is an important structure on a precision machine tool used to transfer machined workpieces to a conveying device. Its structure is disclosed in Chinese Utility Model Patent No. CN214778609U. The bottom end of the receiving device is connected to the conveying device. The machined workpiece is transferred downward from the receiving device to the conveying device, which then transports it out and collects it. In this type of structure, the receiving device has a fixed position and a fixed height, which not only occupies a lot of space, but also restricts the movement space of the cutting tool and the sub-spindle of the machine tool when processing the workpiece. Therefore, the receiving device is prone to interfering with the processing of the workpiece and restricting the movement range of the cutting tool and the sub-spindle of the machine tool. Summary of the Invention

[0003] The purpose of this invention is to provide a receiving device for precision machine tools, which solves the technical defects of existing receiving devices that occupy a large space and easily interfere with the processing of workpieces.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a receiving device for a precision machine tool, including a receiving box bracket, a receiving box, and a receiving box driving device. The lower end of the receiving box bracket is set at one end of the conveying device through a bracket mounting plate. A feeding port is provided on one side of the upper part of the receiving box. The receiving box is set on the receiving box bracket and can slide relative to the receiving box bracket. The feeding port is used to receive the processed workpiece. The receiving box driving device is set on the bracket mounting plate and connected to the receiving box. It is used to drive the receiving box to move relative to the receiving box bracket. The receiving box driving device drives the receiving box to move upward to receive the processed workpiece from the machine tool. The workpiece slides downward from the receiving box onto the conveying device and is output by the conveying device. After receiving the workpiece, the receiving box is driven downward by the receiving box driving device. The receiving box in this invention can be driven by the receiving box driving device to move relative to the receiving box support. After receiving the material, the receiving box retracts into the receiving box support, reducing the space occupied by this invention and increasing the distance between this invention and the machine tool sub-spindle and the cutting tool. This can effectively avoid interference to the movement of the cutting tool, machine tool sub-spindle and workpiece during the workpiece processing.

[0005] As a further improvement of this utility model, the cross-sectional shape of the receiving box support is rectangular. The shape of the receiving box matches the shape of the receiving box support and is set inside the receiving box support. The bottom end of the receiving box is open, and the feed port is opened on the upper part of the receiving box near the sub-spindle. After the receiving box extends out of the receiving box support, the sub-spindle of the machine tool moves and puts the processed workpiece into the receiving box through the feed port. In this utility model, the shapes of the receiving box support and the receiving box facilitate relative sliding between the two, and the opening position of the feed port facilitates the sub-spindle of the machine tool to put the workpiece it is holding into the receiving box.

[0006] As a further improvement of this utility model, an observation window I is provided at the front of the receiving box support, and a transparent cover plate I is provided on the observation window I. An observation window II is provided on the front surface of the receiving box, and a transparent cover plate II is provided on the observation window II. By providing cover plate I and cover plate II, this utility model allows for convenient observation of the process of the workpiece falling downwards inside the receiving box and the receiving box support after the receiving box receives the workpiece.

[0007] As a further improvement of this utility model, baffles I are fixed on both the left and right sides of the observation window I on the receiving box bracket. Pressure plates I are arranged facing each other at the front ends of the two baffles I. A cover plate I is located between the two baffles I and supported by the receiving box bracket. The pressure plates I limit the position of the cover plate I from its front surface. This utility model, through the baffles I and the pressure plates I, can limit the position of the cover plate I, facilitating its fixation during use.

[0008] As a further improvement of this utility model, a protrusion is provided at the front of the receiving box bracket below the observation window I, for supporting the bottom end of the cover plate I upwards. By providing the protrusion, this utility model can support the cover plate I from the bottom, further facilitating the fixing of the cover plate I.

[0009] As a further improvement of this utility model, L-shaped baffles II are fixed at each of the four corners of the receiving box. The baffle II located at the front of the receiving box forms a slot with the receiving box, and the bottom end of the slot is connected to the bottom end of the receiving box by an end plate. The two ends of the cover plate II are respectively disposed within the two slots, and the bottom end of the cover plate II is supported upwards by the end plate. By setting baffles II, this utility model reduces the contact area with the receiving box support, thus reducing the resistance to the movement of the receiving box. Furthermore, the slots formed between the baffles II and the receiving box facilitate the installation of the cover plate II.

[0010] As a further improvement of this utility model, the receiving box driving device is a cylinder, the cylinder body of which is mounted on the bracket mounting plate, and the piston rod is connected to the receiving box. The extension and retraction of the piston rod of the cylinder is used to drive the receiving box to move relative to the receiving box bracket. This utility model drives the movement of the receiving box by the extension and retraction of the cylinder piston rod, which is simple in structure and easy to install.

[0011] As a further improvement of this utility model, a connecting plate is fixed to the upper part of the rear surface of the receiving box, and the piston rod of the cylinder is connected to the connecting plate. This utility model facilitates the connection between the cylinder and the receiving box by fixing the connecting plate to the receiving box.

[0012] As a further improvement of this utility model, the cylinder body is fixedly connected to the bracket mounting plate, and the upper end of its piston rod is inclined backward and parallel to the receiving box bracket. The piston rod of the cylinder is fixedly connected to the connecting plate. In this utility model, the piston rod of the cylinder is parallel to the receiving box bracket, which facilitates the extension and retraction of the piston rod.

[0013] As a further improvement of this utility model, the upper end of the receiving box bracket is inclined backward, and a through hole is provided on the top of the bracket mounting plate, communicating with the receiving box bracket. The receiving box bracket is fixed to the machine tool bed, and the through hole is located directly above the conveying device. In this utility model, the receiving box bracket is inclined, which, together with the inclined setting of the receiving box, can reduce the volume of the receiving box bracket, while the through hole on the bracket mounting plate allows the workpiece to fall downward onto the conveying device.

[0014] In summary, the beneficial effects of this utility model are: the receiving box in this utility model can extend and retract relative to the receiving box bracket under the drive of the receiving box driving device, so that it is in a retracted state when not receiving materials, reducing the space occupied by the whole, and increasing the distance between it and the cutting tool and the machine tool sub-spindle, so as not to interfere with the processing of the workpiece.

Detailed Implementation

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] A conveying device 5 is provided on the machine tool bed. The conveying device 5 is located on one side of the machine tool sub-spindle 7 on the machine tool bed. During workpiece processing, the machine tool main spindle first processes the workpiece from one end, and then the machine tool sub-spindle 7 takes the workpiece and the cutting tool processes the workpiece from the other side to obtain the finished workpiece. The conveying device 5 then transports the finished workpiece to the edge of the machine tool and collects it. This utility model is provided on the conveying device 5 to receive the processed workpiece from the machine tool sub-spindle 7 and send it to the conveying device 5. The conveying device 5 in this utility model is driven by a motor and belt, which is the prior art and will not be described in detail in this utility model.

[0021] like Figures 1 to 4 The precision machine tool receiving device shown includes a receiving box bracket 1, a receiving box 2, and a receiving box drive device 3. The lower end of the receiving box bracket 1 is mounted on one end of the conveying device 5 via a bracket mounting plate 4, and the receiving box bracket 1 is located above the conveying device 5. A feed port 6 is provided on the upper side of the receiving box 2. The workpiece processed by the machine tool sub-spindle 7 can be fed into the receiving box 2 through the feed port 6. The receiving box 2 is mounted on the receiving box bracket 1 and can slide relative to the receiving box bracket 1. During processing by the machine tool sub-spindle 7... When the workpiece is finished, the receiving box 2 moves upward relative to the receiving box bracket 1 so that the feed port 6 is directly facing the machine tool sub-spindle 7. The finished workpiece is received by the feed port 6. After the workpiece is received by the feed port 6, the receiving box 2 moves downward relative to the receiving box bracket 1 to avoid interference with the machine tool sub-spindle 7 and the tool in processing the next workpiece. The receiving box drive device 3 in this utility model is set on the bracket mounting plate 4 and connected to the receiving box 2. The receiving box drive device 3 is used to drive the receiving box 2 to move relative to the receiving box bracket 1.

[0022] In this invention, after the sub-spindle 7 of the machine tool finishes processing the workpiece, the receiving box 2 is driven upward by the receiving box drive device 3 until the feed port 6 is directly opposite the sub-spindle 7. The sub-spindle 7 moves towards the feed port 6, placing the workpiece it holds into the feed port 6, so that the feed port 6 receives the workpiece processed by the machine tool. Due to gravity, the workpiece slides downward in the receiving box 2 and falls onto the conveying device 5, which then transports it. After receiving the workpiece, the receiving box 2 is driven downward by the receiving box drive device 3, increasing the distance between the receiving box 2 and the sub-spindle 7, thus preventing interference with the movement of the sub-spindle 7 and the processing of the workpiece by the cutting tool.

[0023] like Figures 1 to 4As shown, the cross-sectional shape of the receiving box bracket 1 in this utility model is rectangular, that is, the receiving box bracket 1 is a rectangular shell structure. The bottom end of the receiving box bracket 1 is open so that the workpiece can fall onto the conveying device 5. The shape of the receiving box 2 matches the shape of the receiving box bracket 1 and is set inside the receiving box bracket 1. The bottom end of the receiving box 2 is open so that the workpiece can fall from the bottom end of the receiving box 2 onto the conveying device 5 instead of being collected in the receiving box 2. The feed port 6 is opened on the upper part of the receiving box 2 near the sub-spindle 7. Thus, after the receiving box 2 extends out of the receiving box bracket 1, the sub-spindle 7 of the machine tool moves and puts the processed workpiece into the receiving box 2 from the feed port 6.

[0024] like Figures 1 to 4 As shown, the optimal embodiment of this invention features an observation window I8 at the front of the receiving box bracket 1. The observation window I8 is rectangular, and a rectangular transparent cover plate I9 is ​​provided on the observation window I8. In this invention, baffles I12 are fixed on both the left and right sides of the observation window I8 on the receiving box bracket 1. Pressure plates I13 are provided facing each other at the front ends of the two baffles I12. The cover plate I9 is ​​located between the two baffles I12, which limit it from both sides to prevent the cover plate I9 from moving in the left and right directions. The edge of the cover plate I9 is ​​in contact with the front surface of the receiving box bracket 1 around the observation window I8 and is supported by the receiving box bracket 1. The two pressure plates I13 limit it from the front surface of the cover plate I9. In this invention, a long strip-shaped protrusion 14 is provided at the front of the material box bracket 1 below the observation window I8 along the left and right directions. The protrusion 14 is used to support the bottom end of the cover plate I9 upwards.

[0025] like Figures 1 to 4 As shown, this utility model has a rectangular observation window II10 on the front surface of the receiving box 2, and a transparent cover plate II11 on the observation window II10. At each of the four corners of the receiving box 2, there is a baffle plate II15 with an L-shaped cross-section. The baffle plate II15 at the front of the receiving box 2 forms a slot 16 with the receiving box 2. The two ends of the cover plate II11 are respectively set in the two slots 16. When installing the baffle plate II15, the baffle plate II15 can be inserted into the slot 16 from the top of the slot 16. In this utility model, the bottom end of the slot 16 is connected to the bottom end of the receiving box 2 by the end plate 17. The bottom end of the cover plate II11 is supported upward by the end plate 17 to prevent the cover plate II11 from sliding out of the bottom end of the groove 16.

[0026] like Figures 1 to 4As shown, the receiving box driving device 3 in this utility model uses a cylinder. The cylinder body is mounted on the bracket mounting plate 4, and the piston rod of the cylinder is connected to the receiving box 2. The extension and retraction of the piston rod drives the receiving box 2 to move relative to the receiving box bracket 1. When the piston rod extends, it pushes the receiving box 2 upward, and when it retracts, it pulls the receiving box 2 into the receiving box bracket 1. A connecting plate 18 is fixed to the upper part of the rear surface of the receiving box 2. This connecting plate 18 is perpendicular to the rear surface of the receiving box 1, and the piston rod of the cylinder is connected to the connecting plate 18. Preferably, the cylinder body of this utility model is fixedly connected to the bracket mounting plate 4 with multiple bolts, and the upper end of the piston rod of the cylinder is inclined backward and parallel to the receiving box bracket 1. The piston rod of the cylinder is fixedly connected to the connecting plate 18.

[0027] like Figures 1 to 4 As shown, the upper end of the receiving box bracket 1 in this utility model is tilted backward, and a through hole is provided on the top of the bracket mounting plate 4 so that the bracket mounting plate 4 and the receiving box bracket 1 are connected. The bracket mounting plate 4 and the receiving box bracket 1 can be fixed by welding to increase the connection strength between the two. The receiving box bracket 1 is fixed to the bed of the machine tool and the through hole is located directly above the conveying device 5.

[0028] In this invention, a bar stock held by the main spindle of a machine tool is processed from one end by a cutting tool to obtain a semi-finished workpiece. The sub-spindle 7 of the machine tool receives and clamps the semi-finished workpiece, and then the cutting tool cuts the semi-finished workpiece off the bar stock. The cutting tool then processes the unprocessed end of the semi-finished workpiece to obtain the finished workpiece. After the workpiece is processed, the receiving box 2 is driven by a cylinder to move backward and upward until it is directly opposite the feed port 6. The sub-spindle 7 of the machine tool moves to drop the workpiece from the feed port 6 into the receiving box 2, and it falls downward into the conveying device 5, where it is transported and collected. After receiving the workpiece, the receiving box 2 is driven by a cylinder to retract downward into the receiving box bracket 1. The sub-spindle 7 of the machine tool is used to receive and process the next workpiece.
