Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a material receiving device inside a machine tool. Background Art

[0002] With the continuous improvement of the degree of automation, after the completion of the processing of cylindrical workpieces, the initial reliance on manual unloading has changed to automatic unloading and unloading directly in the machine. For example, a machine tool material receiving device disclosed in the patent application No. 201822118807.1 includes a rotating drive member fixed on the machine tool, a swing arm is fixed on the rotating shaft of the rotating drive member, a material receiving box is fixed on the swing arm, the material receiving box has a feed port and a discharge port, and the material receiving box is elastically hinged to close the discharge port. The machine tool material receiving device also includes a material unloading barrel fixed at the front end of the machine tool, the material unloading barrel has a material unloading port and a blanking port, and a resistance part is provided at the material unloading port on the material unloading barrel, and the rotating drive member can drive the material receiving box to swing back and forth between the machine tool spindle and the front end of the machine tool, when the material receiving box is located at the machine tool spindle, the feed port faces upward, and when the material receiving box is located at the front end of the machine tool, the discharge port is docked with the material receiving port, and the resistance part acts on the bottom plate to rotate the bottom plate to open the discharge port. After the workpiece is processed, the rotating driving part moves to rotate the receiving box from the front end of the machine tool to the main shaft of the machine tool, with the feed port facing upwards towards the workpiece and the discharge port being closed by the bottom plate. The workpiece is then cut off and falls into the receiving box. Then the rotating driving part moves in the opposite direction to rotate the receiving box from the main shaft of the machine tool to the front end of the machine tool. The discharge port of the receiving box docks with the receiving port of the discharge barrel, and the resistance part on the discharge barrel acts on the bottom plate to rotate the bottom plate to open the discharge port. The discharge port is connected with the receiving port, and the workpiece slides out of the receiving box from the discharge port and falls out of the discharge barrel from the dropping port after passing through the receiving port.

[0003] In the process of feeding the workpiece from the machine tool spindle into the discharge barrel, it is necessary to prevent the workpiece connected to the receiving box from falling out directly during the swinging of the swing arm. For this purpose, the above-mentioned machine tool receiving device elastically hinges a bottom plate that closes the discharge port on the receiving box, so as to prevent the workpiece from falling out directly from the discharge port. However, the feed port is always open, and the receiving box is in an upward state when receiving materials and in a backward state when discharging materials. That is to say, the feed port is slowly switched from upward to backward in the entire process from receiving materials to discharging materials, resulting in the possibility that the workpiece may fly out directly from the feed port during this process. Therefore, the above-mentioned machine tool receiving device has the problem of insufficient reliability in use. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems existing in the prior art and propose a material receiving device inside a machine tool to solve the problem of insufficient reliability in use.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A material receiving device inside a machine tool comprises a material receiving mechanism arranged in the machine tool and a material unloading member fixed in the machine tool and located below the material receiving mechanism, the material receiving mechanism comprising a swinging cylinder, a swing arm fixedly connected to the end of the output shaft of the swinging cylinder, and a material unloading member fixedly connected to the end of the swing arm, the material unloading member having a material unloading trough, characterized in that the material receiving member is in the shape of a funnel with one end closed, the swinging of the swing arm can make the material receiving member switch from an upward mouth to a downward mouth, the material receiving member is integrally connected with a hook-shaped material blocking portion at one side edge in the mouth, the material unloading member is fixedly connected with a material blocking member in the material unloading trough, the material blocking member has a material blocking portion, the material blocking portion is located on the active path of the material receiving member as the swinging of the swing arm, the material receiving member has a makeshift groove that simultaneously penetrates the side of the material receiving member and the material blocking portion and can allow the material blocking portion to pass through.

[0007] The swing arm is driven by the swing cylinder to swing until the receiving piece is in a state where the mouth of the receiving piece is facing upward, and the processed workpiece falls into the receiving piece. Then, the swing arm is driven by the swing cylinder to swing downward so that the receiving piece switches from the state where the mouth of the receiving piece is facing upward to the state where the mouth of the receiving piece is facing downward to the top of the material discharge chute. Since the receiving piece is integrally connected with a hook-shaped material stopper at one side edge inside the mouth of the receiving piece, in the process of switching the receiving piece from the state where the mouth of the receiving piece is facing upward to the state where the mouth of the receiving piece is facing downward, the workpiece will be hooked by the material stopper at the mouth of the receiving piece and cannot fall out of the receiving piece (in practice, during the swing of the swing arm, the workpiece moves along the inner side surface of the receiving piece, and the material stopper is set at one side edge of the mouth where the inner side surface is located), thereby ensuring reliability of use. The blocking part is fixedly connected to the material discharge piece in the material discharge chute, and the blocking part has a blocking portion, which is located on the movable path of the material receiving piece as the swing arm swings. The material receiving piece has a clearance groove that penetrates the side of the material receiving piece and the blocking portion and can allow the blocking portion to pass through. When the material receiving piece swings to the position of the blocking portion, as the material receiving piece continues to swing, the blocking portion will pass through the clearance groove and abut against the workpiece and block the workpiece, so that the workpiece can smoothly escape from the material receiving piece and fall into the material discharge chute.

[0008] The internal material receiving device of this machine tool is configured with a material receiving piece in the shape of a funnel with one end closed and a hook-shaped material blocking part integrally connected to one side of the mouth of the material receiving piece. The material blocking part can hook the workpiece during the swinging of the swing arm, so that the workpiece will not fall out of the material receiving piece during operation, thereby improving the reliability of use. The setting of the clearance groove and the material blocking part ensures that the workpiece can still be smoothly unloaded from the material receiving piece in the end.

[0009] In the above-mentioned internal material receiving device of a machine tool, the length of the material blocking portion along one side of the mouth of the material receiving piece is the same as the side of the mouth of the material receiving piece.

[0010] The workpiece is columnar, and the length of the blocking part along one side of the mouth of the receiving piece is made the same as that of the side of the mouth of the receiving piece, so that the entire workpiece can be hooked by the blocking part, so that the workpiece will not be skewed and slide out of the mouth of the receiving piece when the receiving piece switches from an upward mouth state to a downward mouth state.

[0011] In the above-mentioned internal material receiving device of the machine tool, the number of the said clearance grooves is several, and the number of the material blocking parts is the same as the clearance grooves.

[0012] Through the above arrangement, the workpiece can be well pushed out of the material receiving piece when it abuts against the material blocking portion.

[0013] In the above-mentioned internal material receiving device of a machine tool, the clearance groove is in the shape of a strip, the material blocking portion is in the shape of a sheet, and the width of the clearance groove is greater than the width of the material blocking portion.

[0014] In the above-mentioned internal material receiving device of the machine tool, the unloading part includes an outer box body fixedly connected to the machine tool and an inner box body arranged in the outer box body. The inner box body is drawer-shaped and the rear end of the inner box body is open. The inner box body can extend backward out of the rear end of the outer box body. The unloading trough is the inner cavity of the inner box body, and the front end of the outer box body extends out of the machine tool. A material removal port is provided on the upper side of the front end of the outer box body.

[0015] When receiving materials, the inner box extends backwards out of the rear end of the outer box. The workpiece that falls from the receiving piece into the material chute will roll into the front end of the outer box, and then the staff can directly take the workpiece out from the material taking port. When the workpiece is in the normal processing state, the inner box retracts into the outer box to prevent interference with the movement of some mechanisms that need to be translated left and right.

[0016] In the above-mentioned internal material receiving device of the machine tool, a linear drive cylinder is fixedly connected to the bottom of the outer box body, and the piston rod of the linear drive cylinder is arranged backward. A connecting block is fixedly connected to the bottom of the inner box body, and the connecting block is fixedly connected to the piston rod of the linear drive cylinder.

[0017] When the piston rod of the linear drive rod cylinder is extended, the inner box body can be driven to extend backward out of the outer box body; when the piston rod of the linear drive cylinder is retracted, the inner box body can be driven to retract forward into the outer box body.

[0018] In the above-mentioned internal material receiving device of the machine tool, the material blocking member has a connecting plate, which is fixedly connected to the left and right side walls of the material discharge trough respectively, and each material blocking part is fixedly connected to the upper side of the connecting plate.

[0019] In the above-mentioned machine tool internal material receiving device, a material shifting piece which can move in the left-right direction and the front-back direction is provided in the machine tool, and the end of the material shifting piece has a strip-shaped material shifting portion arranged in the front-back direction.

[0020] Generally speaking, cylindrical workpieces are processed on machine tools after being clamped by a three-jaw chuck. If the processed part is cut off directly after processing, the cut workpiece can be directly received by the receiving piece. However, some workpieces do not need to be cut after processing. The three-jaw chuck only loosens the workpiece, but the workpiece is still on the three-jaw chuck and will not fall directly. For this reason, a material-pickup piece that can move in the left and right directions and in the front and back directions is provided in the machine tool. The end of the material-pickup piece has a strip-shaped material-pickup part arranged in the front and back directions. In this way, after the workpiece is processed and loosened by the three-jaw chuck, the material-pickup part can be inserted into the gap between the rear end of the workpiece and the disc body of the three-jaw chuck through the movement of the material-pickup piece, and the workpiece can be pushed out of the three-jaw chuck to ensure that it can fall into the receiving piece. Through the setting of the material-pickup piece, the internal receiving device of the machine tool can realize automatic material receiving in the machine, whether it is for the workpiece that needs to be cut off after processing or the workpiece that does not need to be cut off after processing, thereby improving the applicability.

[0021] In the above-mentioned machine tool internal material receiving device, a turret is provided inside the machine tool, a connecting seat is fixedly connected to the outer peripheral surface of the turret, and a material removing piece is fixedly connected to the connecting seat.

[0022] A connecting seat is fixedly connected to the outer peripheral surface of the turret and the material shifting piece is fixedly connected to the connecting seat, so that the turret-specific saddle unit can be used to realize the movement of the material shifting piece. There is no need to set up a separate moving unit specifically for realizing the movement of the material shifting piece, which greatly saves the internal space of the machine tool.

[0023] Compared with the existing technology, the internal material receiving device of this machine tool has the following advantages:

[0024] 1. The material receiving piece is provided in a funnel shape with one end closed and a hook-shaped material blocking part is integrally connected to one side of the mouth of the material receiving piece. The material blocking part can be used to hook the workpiece during the swinging of the swing arm, so that the workpiece will not fall out of the material receiving piece during operation, thereby improving the reliability of use;

[0025] 2. A material blocking piece is fixedly connected to the material unloading piece in the material unloading chute, the material blocking piece has a material blocking portion, the material blocking portion is located on the movable path of the material receiving piece as the swing arm swings, and the material receiving piece has a clearance groove that penetrates the side of the material receiving piece and the material blocking portion and can be passed through by the material blocking portion, so that the material blocking portion can pass through the clearance groove and abut against the workpiece and block the workpiece, so that the workpiece can finally smoothly escape from the material receiving piece and fall into the material unloading chute;

[0026] 3. Through the setting of the material shifting piece, the internal material receiving device of this machine tool can realize automatic material receiving inside the machine, whether it is for the workpiece that needs to be cut off after processing or the workpiece that does not need to be cut off after processing, thereby improving the applicability.

DETAILED DESCRIPTION

[0037] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0038] like Figure 1-Figure 4As shown, a material receiving device inside a machine tool, the machine tool has a first spindle box and a second spindle box 1 located on the right side of the first spindle box, the first spindle box is provided with a first spindle, the second spindle box 1 is provided with a second spindle, the first spindle and the second spindle are arranged opposite to each other, and the material receiving device inside the machine tool includes a material receiving mechanism arranged in the machine tool and a material unloading member 2 fixed in the machine tool and located below the material receiving mechanism. Among them, the material receiving mechanism includes a swing cylinder 3 fixedly connected to the left end of the box body of the second spindle box 1, a swing arm 4 fixedly connected to the end of the output shaft of the swing cylinder 3, and a material receiving member 5 fixedly connected to the end of the swing arm 4, the end of the output shaft of the swing cylinder 3 is arranged to the left, the material receiving member 5 is in the shape of a funnel with one end closed, the swing arm 4 includes a straight first arm body 4a and a second arm body 4b with one end fixedly connected to the left end side of the straight rod, and the closed end of the material receiving member 5 is fixedly connected to the other end of the second arm body 4b. The material discharge piece 2 has a material discharge chute 2a, and the swing arm 4 can swing to switch the material receiving piece 5 from a position with its mouth facing upward and below the second spindle to a position with its mouth facing downward and above the material discharge chute 2a.

[0039] Furthermore, if Figure 2-Figure 7 As shown, the material receiving member 5 is integrally connected with a hook-shaped material blocking portion 5a at one side of the mouth, and the length of the material blocking portion 5a in the left-right direction is the same as the side of the mouth. The material discharging member 2 is fixedly connected with a material blocking member 6 in the material discharging trough 2a, and the material blocking member 6 has a material blocking portion 6a, and the material blocking portion 6a is located on the active path of the material receiving member 5 swinging with the swing arm 4. The material receiving member 5 has a clearance groove 5b that penetrates the side of the material receiving member 5 and the material blocking portion 5a at the same time and allows the material blocking portion 6a to pass through. The number of the clearance grooves 5b is several, and the number of the material blocking portions is the same as that of the clearance grooves 5b. The clearance grooves 5b are strip-shaped, and the material blocking portions are sheet-shaped. The width of the clearance grooves 5b is greater than the width of the material blocking portion 6a.

[0040] The workpiece is first processed on the first spindle. After the processing is completed, the entire second spindle box 1 moves toward the first spindle box, and the three-jaw chuck on the second spindle clamps the workpiece and then moves it to the initial position for another sequence of processing. After the final processing is completed, the swing cylinder 3 drives the swing arm 4 to swing until the receiving piece 5 is in a state where the mouth is facing up and is located below the second spindle. The processed workpiece will fall into the receiving piece 5. This state is as shown in the figure. Figure 2As shown. Then, the swing arm 4 is driven by the swing cylinder 3 to swing downward so that the material receiving piece 5 switches from the state with the mouth facing upward to the state with the mouth facing downward to the top of the material discharge chute 2a. Since the material receiving piece 5 is integrally connected with a hook-shaped material blocking portion 5a at one side edge inside the mouth, in the process of switching the material receiving piece 5 from the state with the mouth facing upward to the state with the mouth facing downward, the workpiece will be hooked by the material blocking portion 5a at the mouth of the material receiving piece 5 and cannot fall out of the material receiving piece 5 (in practice, during the swinging of the swing arm 4, the workpiece moves along the inner side surface of the material receiving piece 5, and the material blocking portion 5a is set at one side edge of the mouth where the inner side surface is located), thereby ensuring the reliability of use. The state of the material receiving mechanism during the swinging of the swing arm 4 is shown as follows. Figure 3 and Figure 4 As shown. Since the material unloading member 2 is fixedly connected with the material blocking member 6 in the material unloading trough 2a, the material blocking member 6 has a material blocking portion 6a, and the material blocking portion 6a is located on the active path of the material receiving member 5 as the swing arm 4 swings, and the material receiving member 5 has a clearance groove 5b that penetrates the side of the material receiving member 5 and the material blocking portion 5a at the same time and allows the material blocking portion to pass through, then when the material receiving member 5 swings to the position of the material blocking portion 6a, as the material receiving member 5 continues to swing, the material blocking portion 6a will be as shown. Fig. 9 As shown in the figure, the workpiece passes through the clearance groove 5b and abuts against the workpiece and blocks the workpiece, so that the workpiece can smoothly escape from the material receiving member 5 and fall into the material discharge groove 2a.

[0041] Furthermore, if Figure 6 and Figure 7As shown, the material removal part 2 includes an outer box body 2b fixedly connected to the machine tool and an inner box body 2c arranged in the outer box body 2b, the inner box body 2c is in the shape of a drawer and the rear end of the inner box body 2c is open, the inner box body 2c can extend backwards outside the rear end of the outer box body 2b, the material removal chute 2a is the inner cavity of the inner box body 2c, the front end of the outer box body 2b extends out of the machine tool, and the upper side of the front end of the outer box body 2b is provided with a material removal port 2b1. The material blocking part 6 has a connecting plate 6b, and the connecting plate 6b is respectively fixedly connected to the left and right side walls of the material removal chute 2a, and each material blocking part 6a is fixedly connected to the upper side of the connecting plate 6b. In practice, the machine tool has an external protective cover 9, and the front side plate of the external protective cover 9 has an installation port, and the outer box body 2b passes through the installation port and is fixedly connected to the front side plate of the external protective cover 9. When it is necessary to connect the material, the inner box body 2c extends backwards outside the rear end of the outer box body 2b. The workpiece that falls from the material receiving member 5 into the material discharge chute 2a will roll into the front end of the outer box body 2b, and then the staff can directly take the workpiece from the material taking port 2b1. When the workpiece is in the normal processing state, the inner box body 2c is retracted into the outer box body 2b to prevent interference with the actions of some mechanisms that need to be translated left and right. The bottom of the outer box body 2b is fixedly connected with a linear drive cylinder 7, and the piston rod of the linear drive cylinder 7 is set backward. The bottom of the inner box body 2c is fixedly connected with a connecting block 8, and the connecting block 8 is fixedly connected to the piston rod of the linear drive cylinder 7. When the piston rod of the linear drive rod cylinder is extended, the inner box body 2c can be driven to extend backward outside the outer box body 2b; when the piston rod of the linear drive cylinder 7 is retracted, the inner box body 2c can be driven to retract forward into the outer box body 2b. In this embodiment, the bottom of the outer box body 2b is fixedly connected with a cover, and the linear drive cylinder 7 is located on the inner side of the cover.

[0042] Furthermore, if Figure 1 , Figure 2 and Figure 8As shown, a material-diverting piece 10 capable of moving in the left-right direction and in the front-back direction is provided in the machine tool, and the end of the material-diverting piece 10 has a material-diverting portion 10a arranged in the front-back direction. Generally speaking, columnar workpieces are processed on the machine tool after being clamped by a three-jaw chuck. If the processed part is cut off directly after processing, the cut workpiece can be directly received by the material receiving piece 5. However, some workpieces do not need to be cut off after processing, and the three-jaw chuck only releases the workpiece but the workpiece is still on the three-jaw chuck and will not fall directly. For this reason, a material-diverting piece 10 capable of moving in the left-right direction and in the front-back direction is provided in the machine tool, and the end of the material-diverting piece 10 has a material-diverting portion 10a arranged in the front-back direction. In this way, after the workpiece is processed and released by the three-jaw chuck, the material-diverting portion 10a can be inserted into the gap between the rear end of the workpiece and the disc body of the three-jaw chuck through the movement of the material-diverting piece 10, and the workpiece is pushed out of the three-jaw chuck to ensure that it can fall into the material receiving piece 5. By setting the material-pickup piece 10, the material-pickup device inside the machine tool can realize automatic material-pickup in the machine, whether it is for workpieces that need to be cut after processing or for workpieces that do not need to be cut after processing, thereby improving applicability. In this embodiment, a turret 11 is provided inside the machine tool, and a connecting seat 12 is fixedly connected to the outer peripheral surface of the turret 11. The material-pickup piece 10 is fixedly connected to the connecting seat 12, so that the saddle unit dedicated to the turret 11 can be used to realize the movement of the material-pickup piece 10, and there is no need to set up another moving unit specifically for realizing the movement of the material-pickup piece 10, which greatly saves the internal space of the machine tool.

[0043] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
