Description

Technical Field

[0001] This invention relates to the field of flow guiding tooling technology, and in particular to a flow guiding tooling for improving blade grinding performance. Background Technology

[0002] A flow guide fixture is a device used to guide the flow of coolant. When using a flow guide fixture, it is added to the right side of the fixture. A U-shaped groove is designed under the fixture to facilitate the back-and-forth sliding of the flow guide plate, which facilitates the removal of the part from the fixture without interference. Two limit pins are designed at its end to prevent the flow guide plate from sliding out of the flow guide fixture. At the same time, slots are cut on both end faces to facilitate the connection and fixation of the fixture to the machine tool table. Threaded holes are drilled on the surface to fix the flow guide plate fixture in its position. Because a baffle is set on one side of the fixture, it can prevent the flow guide fixture from colliding with the fixture and the part, and can play a limiting role. An L-shaped flow guide plate is set on the top of the fixture to avoid interference with the fixture and increase the flow channel surface area. A V-shaped groove is set to guide the flow of coolant. A side step is added to prevent the coolant from flowing to the other side. The large flat surface is extended to the vicinity of the end face of the part so that the coolant can fully cover the blade machining surface.

[0003] The inventors discovered in their daily work that the flow guiding fixture still has at least the following problems: When using the flow guiding fixture, it is added to the right side of the fixture. A U-shaped groove is designed under the fixture to facilitate the back-and-forth sliding of the flow guide plate, which is beneficial for the removal of the part from the fixture without interference. Two limit pins are designed at its end to prevent the flow guide plate from sliding out of the flow guiding fixture. At the same time, slots are opened on both end faces to facilitate the connection and fixation of the fixture to the machine tool table. Threaded holes are drilled on the surface to fix the flow guide plate fixture state. Because a baffle is set on one side of the fixture, it can prevent the flow guiding fixture from colliding with the fixture and the part, which can play a limiting role. An L-shaped flow guide plate is set on the top of the fixture to avoid interference with the fixture and increase the flow channel surface area. A V-shaped groove is set to guide the flow of coolant. A side step is added to prevent coolant from flowing to the other side. The large plane is extended to the vicinity of the end face of the part so that the coolant can fully cover the blade machining surface. However, in actual use, when machining the blade, the fixture is set on one side of the blade. Long-term use may cause the temperature of the fixture to rise, which may affect the heat dissipation to a certain extent. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flow guide tool to improve blade grinding performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flow guiding fixture for improving blade grinding performance, comprising a base plate, mounting grooves on both sides of the base plate, a U-shaped groove on the top of the base plate, a flow guiding plate slidably connected to the inner wall of the U-shaped groove, a limiting pin inserted through one side of the base plate, a baffle plate installed on one side of the base plate by bolts, a connecting device provided on one side of the flow guiding plate, the connecting device comprising an iron plate, connecting grooves on both sides of the flow guiding plate, an iron plate slidably connected to the inner wall of the connecting groove, and connecting plates uniformly fixedly connected to one side of the iron plate, the connecting plates connecting the iron plates together.

[0006] The effect achieved by the above components is as follows: when using the connecting device, the iron plate is slid into the inside of the connecting groove. Since the iron plates are connected together by the connecting plate, the iron plates can be placed on both sides of the guide plate. This makes it easier to increase the contact area between the guide plate and the air through the iron plates, which facilitates the heat dissipation of the guide plate.

[0007] Preferably, a connecting block is fixedly connected to the top of one side of the iron plate, a first damping rod is fixedly connected to the top of the connecting block, a fixing plate is fixedly connected to the top of the first damping rod, a first spring is sleeved on the surface of the first damping rod, one end of the first spring is fixedly connected to the top of the connecting block, and the end of the first spring away from the connecting block is fixedly connected to the bottom of the fixing plate. A fixing hole is opened on one side of the fixing plate, a limiting groove is opened on one side of the guide plate, a fixing groove is opened on the side of the limiting groove near the guide plate, the inner wall of the limiting groove is slidably connected to the end of the fixing plate near the guide plate, and the end of the fixing plate away from the first damping rod is slidably connected to the inner wall of the fixing groove.

[0008] The effect achieved by the above components is as follows: the iron plate is slid into the inside of the connecting groove, and then the fixing plate is slid into the inside of the limiting groove. When one end of the fixing plate is slid into the inside of the limiting groove, the fixing plate is pulled towards the connecting block by the first spring. This makes it easier to restrict the fixing plate to the bottom of the inner wall of the fixing groove, and thus restrict the fixing plate to the inside of the limiting groove.

[0009] Preferably, a rotating block is rotatably inserted on one side of the guide plate, and a second damping rod is fixedly connected to the side of the rotating block away from the guide plate. A rectangular plate is fixedly connected to the end of the second damping rod away from the rotating block, and a rubber block is fixedly connected to the side of the rectangular plate near the second damping rod. The rubber block is disposed at the top of the inner wall of the limiting groove. A second spring is sleeved on the surface of the second damping rod, and one end of the second spring is fixedly connected to one side of the rotating block. The end of the second spring near the rectangular plate is fixedly connected to one side of the rectangular plate.

[0010] The effect achieved by the above components is as follows: when the fixed plate is confined inside the fixed groove, the rotating block is manually controlled to rotate, and then the rectangular plate is pulled towards the rotating block by the second spring, thus confining the rubber block to the top of the fixed plate.

[0011] Preferably, a rubber rod is fixedly connected to the bottom of the inner wall of the limiting groove, and the rubber rod is slidably connected to the inner wall of the fixing hole.

[0012] The effect achieved by the above components is to squeeze the rubber rod into the inside of the fixing hole, so that the fixing plate can be set at the bottom of the inner wall of the limiting groove.

[0013] Preferably, a positioning groove is provided on one side of the guide plate, and a positioning strip is slidably connected to the inner wall of the positioning groove. The positioning strip is slidably inserted through and inserted into one side of the iron plate. A third damping rod is fixedly connected to one side of the inner wall of the positioning groove. The end of the third damping rod away from the positioning groove is fixedly connected to one end of the positioning strip. A third spring is sleeved on the surface of the third damping rod. One end of the third spring is fixedly connected to one side of the inner wall of the positioning groove, and the end of the third spring near the positioning strip is fixedly connected to one side of the positioning strip.

[0014] The effect achieved by the above components is that the positioning strip is pressed away from the positioning groove by the third spring, so that the positioning strip passes through one side of the iron plate, thereby confining the iron plate inside the connecting groove.

[0015] Preferably, a limiting device is provided on the top of the base plate. The limiting device includes a fixed frame. A rectangular groove is formed on the top of the baffle. The inner wall of the rectangular groove is slidably connected to the fixed frame. A fourth damping rod is fixedly connected to the side of the fixed frame near the base plate. A circular plate is fixedly connected to the end of the fourth damping rod away from the fixed frame. A fourth spring is sleeved on the surface of the fourth damping rod. One end of the fourth spring is fixedly connected to one side of the fixed frame. The end of the fourth spring away from the fixed frame is fixedly connected to one side of the circular plate. A sliding block is fixedly connected to the end of the circular plate away from the fourth damping rod. A circular groove is formed on one side of the guide plate. A sliding groove is formed on the side of the circular groove near the guide plate. The inner wall of the sliding groove is slidably connected to the sliding block. A rubber ring is fixedly connected to the inner wall of the circular groove.

[0016] The effect achieved by the above components is as follows: when using the limiting device, the fixed frame is slid into the inside of the rectangular groove, the circular plate is slid into the inside of the circular groove, and then the sliding block is slid into the inside of the sliding groove. In this way, the circular plate can be restricted inside the circular groove by the rubber ring, and then the circular plate is pressed away from the baffle by the fourth spring. This makes it easier to set the guide plate on one side of the workpiece.

[0017] Preferably, the surfaces of the fourth damping rod and the fourth spring are covered with rubber sleeves, one end of the rubber sleeve is fixedly connected to one side of the fixed frame, and the end of the rubber sleeve away from the fixed frame is fixedly connected to one side of the circular plate.

[0018] The effect achieved by the above components is that by fitting the rubber sleeve onto the surface of the fourth damping rod and the fourth spring, it is possible to prevent debris from getting stuck inside the fourth spring.

[0019] Preferably, a positioning rod is fixedly connected to the side of the baffle away from the bottom plate. The positioning rod is slidably inserted through one side of the fixed frame. A fifth spring is sleeved on the surface of the positioning rod. One end of the fifth spring is fixedly connected to the end of the positioning rod away from the baffle, and the end of the fifth spring near the baffle is fixedly connected to the side of the baffle away from the bottom plate.

[0020] The effect achieved by the above components is that the positioning rod passes through one side of the baffle and the fixed frame, and then the positioning rod is pulled towards the baffle by the fifth spring, so that the positioning rod can be confined inside the fixed frame.

[0021] In this invention, by setting a connecting device, when using the connecting device, the iron plate is slid into the inside of the connecting groove. Since the iron plates are connected together by the connecting plate, the iron plates can be set on both sides of the guide plate. This makes it easier to increase the contact area between the guide plate and the air through the iron plates, which facilitates the heat dissipation of the guide plate. Attached Figure Description

[0031] Example 1, such as Figure 1-8 As shown, a flow guiding fixture for improving blade grinding performance has mounting grooves 2 on both sides of a base plate 1, and a U-shaped groove 3 on the top of the base plate 1. A flow guiding plate 4 is slidably connected to the inner wall of the U-shaped groove 3. A limiting pin 5 is inserted through one side of the base plate 1, and a baffle 6 is bolted to one side of the base plate 1. A connecting device 7 is provided on one side of the flow guiding plate 4. When using the flow guiding fixture, a flow guiding fixture is added to the right side of the fixture. The U-shaped groove 3 below the fixture facilitates the back-and-forth sliding of the flow guiding plate 4, which is beneficial for the removal of parts from the fixture without interference. Two limiting pins 5 are designed at its end to prevent the flow guiding plate from sliding backward. The flow plate 4 slides out of the guide fixture, and grooves are cut on both end faces to facilitate the connection and fixation of the fixture to the machine tool table. Threaded holes are drilled on the surface to fix the flow plate 4 fixture in its fixed state. Because a baffle 6 is set on one side of the fixture, it prevents the flow guide fixture from colliding with the fixture and the part, and can play a limiting role. An L-shaped flow plate 4 is set on the top of the fixture to avoid interference with the fixture, increase the flow channel surface area, set a V-shaped groove to guide the flow of coolant, add side steps to prevent coolant from flowing to the other side, and extend the large plane to the vicinity of the end face of the part so that the coolant can fully cover the blade machining surface.

[0032] Reference Figures 3 to 6The connecting device 7 includes an iron plate 702. Connecting grooves 701 are provided on both sides of the guide plate 4. The iron plate 702 is slidably connected to the inner wall of the connecting groove 701. Connecting plates 703 are evenly fixedly connected to one side of the iron plate 702, connecting the iron plates 702 together. When using the connecting device 7, the iron plates 702 are slid into the connecting groove 701. Because the iron plates 702 are connected together by the connecting plates 703, the iron plates 702 can be positioned on both sides of the guide plate 4, thus increasing the contact area between the guide plate 4 and the air, facilitating heat dissipation. A connecting block 704 is fixedly connected to the top of one side of the iron plate 702, and a first damping rod 705 is fixedly connected to the top of the connecting block 704. A fixing plate 706 is fixedly connected to the top of the first damping rod 705. A first spring 707 is sleeved on the surface of the first damping rod 705. One end of the first spring 707 is fixedly connected to the top of the connecting block 704, and the end of the first spring 707 away from the connecting block 704 is fixedly connected to the bottom of the fixing plate 706. A fixing hole 708 is opened on one side of the fixing plate 706, and a limiting groove 709 is opened on one side of the guide plate 4. A fixing groove 710 is opened on the side of the limiting groove 709 near the guide plate 4. The inner wall of the limiting groove 709 is slidably connected to the end of the fixing plate 706 near the guide plate 4, and the end of the fixing plate 706 away from the first damping rod 705 is slidably connected to the inner wall of the fixing groove 710. The iron plate 702 is slid into the inner wall of the connecting groove 701. Then, the fixing plate 706 is slid into the limiting groove 709. When one end of the fixing plate 706 is slid into the limiting groove 709, the first spring 707 pulls the fixing plate 706 towards the connecting block 704. This helps to restrict the fixing plate 706 to the bottom of the inner wall of the fixing groove 710, and thus restrict the fixing plate 706 to the inside of the limiting groove 709. A rotating block 712 is rotatably inserted on one side of the guide plate 4. A second damping rod 713 is fixedly connected to the side of the rotating block 712 away from the guide plate 4. A rectangular plate 715 is fixedly connected to the end of the second damping rod 713 away from the rotating block 712. A rubber block 716 is fixedly connected to the side of the rectangular plate 715 near the second damping rod 713. The rubber block 716 is set in... At the top of the inner wall of the limiting groove 709, a second spring 714 is fitted onto the surface of the second damping rod 713. One end of the second spring 714 is fixedly connected to one side of the rotating block 712, and the end of the second spring 714 near the rectangular plate 715 is fixedly connected to one side of the rectangular plate 715. When the fixed plate 706 is confined inside the fixed groove 710, the rotating block 712 is manually rotated, and then the rectangular plate 715 is pulled towards the rotating block 712 by the second spring 714, thus confining the rubber block 716 to the top of the fixed plate 706. A rubber rod 711 is fixedly connected to the bottom of the inner wall of the limiting groove 709. The rubber rod 711 is slidably connected to the inner wall of the fixed hole 708, squeezing the rubber rod 711 into the interior of the fixed hole 708.This allows the fixing plate 706 to be positioned at the bottom of the inner wall of the limiting groove 709. A positioning groove 717 is provided on one side of the guide plate 4. A positioning strip 718 is slidably connected to the inner wall of the positioning groove 717. The positioning strip 718 is slidably inserted through and inserted into one side of the iron plate 702. A third damping rod 719 is fixedly connected to one side of the inner wall of the positioning groove 717. The end of the third damping rod 719 away from the positioning groove 717 is fixedly connected to one end of the positioning strip 718. A third spring 720 is sleeved on the surface of the third damping rod 719. One end of the third spring 720 is fixedly connected to one side of the inner wall of the positioning groove 717, and the end of the third spring 720 near the positioning strip 718 is fixedly connected to one side of the positioning strip 718. By pressing the positioning strip 718 away from the positioning groove 717 through the third spring 720, the positioning strip 718 passes through one side of the iron plate 702, thereby confining the iron plate 702 inside the connecting groove 701.

[0033] Reference Figure 7 and Figure 8A limiting device 8 is provided on the top of the base plate 1. The limiting device 8 includes a fixed frame 802. A rectangular groove 801 is opened on the top of the baffle 6. The inner wall of the rectangular groove 801 is slidably connected to the fixed frame 802. A fourth damping rod 803 is fixedly connected to the side of the fixed frame 802 near the base plate 1. A circular plate 805 is fixedly connected to the end of the fourth damping rod 803 away from the fixed frame 802. A fourth spring 804 is sleeved on the surface of the fourth damping rod 803. One end of the fourth spring 804 is fixedly connected to one side of the fixed frame 802, and the other end of the fourth spring 804 away from the fixed frame 802 is fixedly connected to one side of the circular plate 805. A sliding block 806 is fixedly connected to the end of the circular plate 805 away from the fourth damping rod 803. A circular groove 807 is formed on one side of the guide plate 4, and a sliding groove 808 is formed on the side of the circular groove 807 near the guide plate 4. The inner wall of the sliding groove 808 is slidably connected to the sliding block 806. A rubber ring 809 is fixedly connected to the inner wall of the circular groove 807. When using the limiting device 8, the fixed frame 802 is slid into the rectangular groove 801, the circular plate 805 is slid into the circular groove 807, and then the sliding block 806 is slid into the sliding groove 808. In this way, the circular plate 805 can be held in place by the rubber ring 809. 5 is confined inside the circular groove 807, and then the fourth spring 804 presses the circular plate 805 away from the baffle 6. This makes it easier to place the guide plate 4 on one side of the workpiece. The surface of the fourth damping rod 803 and the fourth spring 804 is covered with a rubber sleeve 810. One end of the rubber sleeve 810 is fixedly connected to one side of the fixed frame 802, and the end of the rubber sleeve 810 away from the fixed frame 802 is fixedly connected to one side of the circular plate 805. By covering the surface of the fourth damping rod 803 and the fourth spring 804 with the rubber sleeve 810, it is possible to prevent debris from getting stuck inside the fourth spring 804. The baffle 6 is away from the workpiece. A positioning rod 811 is fixedly connected to one side of the base plate 1. The positioning rod 811 is slidably inserted into one side of the fixed frame 802. A fifth spring 812 is sleeved on the surface of the positioning rod 811. One end of the fifth spring 812 is fixedly connected to the end of the positioning rod 811 away from the baffle 6, and the end of the fifth spring 812 near the baffle 6 is fixedly connected to the side of the baffle 6 away from the base plate 1. The positioning rod 811 is passed through the baffle 6 and one side of the fixed frame 802, and then the positioning rod 811 is pulled towards the baffle 6 by the fifth spring 812. In this way, the positioning rod 811 can be restricted inside the fixed frame 802.

[0034] Working principle: When using the flow guide fixture, a flow guide fixture is added to the right side of the fixture. A U-shaped groove 3 is designed below the fixture to facilitate the back-and-forth sliding of the flow guide plate 4, allowing for easy removal of the part from the fixture without interference. Two limiting pins 5 are designed at its end to prevent the flow guide plate 4 from sliding out of the fixture. Grooves are also cut on both end faces to facilitate connection and fixation of the fixture to the machine tool table. Threaded holes are drilled on the surface to fix the flow guide plate 4 in its fixture state. A baffle 6 is set on one side of the fixture to prevent the flow guide fixture from colliding with the fixture or the part, thus providing a limiting function. An L-shaped flow guide plate 4 is set on the top of the fixture to avoid interference with the fixture and increase the flow channel surface area. A V-shaped groove is set to guide the coolant flow direction, and a side step is added to prevent the coolant from flowing to the other side. The coolant flows away, extending the large flat surface to near the end face of the part, so that the coolant can fully cover the machined surface of the blade. When using the connecting device 7, slide the iron plate 702 into the connecting groove 701, and then slide the fixing plate 706 into the limiting groove 709. When one end of the fixing plate 706 is slid into the limiting groove 709, the first spring 707 pulls the fixing plate 706 towards the connecting block 704, which helps to restrict the fixing plate 706 to the bottom of the inner wall of the fixing groove 710. Press the rubber rod 711 into the fixing hole 708, so that the fixing plate 706 can be set at the bottom of the inner wall of the limiting groove 709. Then manually control the rotating block 712 to rotate, and then through the second spring... 714 pulls the rectangular plate 715 towards the rotating block 712, thus restricting the rubber block 716 to the top of the fixed plate 706. The third spring 720 then compresses the positioning strip 718 away from the positioning groove 717, causing the positioning strip 718 to pass through one side of the iron plate 702, thereby restricting the iron plate 702 inside the connecting groove 701. Since the iron plates 702 are connected by the connecting plate 703, they can be positioned on both sides of the guide plate 4, increasing the contact area between the guide plate 4 and the air, thus facilitating heat dissipation. When using the limiting device 8, the fixed frame 802 is slid into the rectangular groove 801, and the positioning rod 81... 1. Passing through one side of the baffle 6 and the fixed frame 802, the positioning rod 811 is pulled towards the baffle 6 by the fifth spring 812, thus restricting the positioning rod 811 inside the fixed frame 802. The circular plate 805 is slid into the circular groove 807, and the sliding block 806 is slid into the sliding groove 808, thus restricting the circular plate 805 inside the circular groove 807 by the rubber ring 809. Then, the circular plate 805 is squeezed away from the baffle 6 by the fourth spring 804, thus facilitating the placement of the guide plate 4 on one side of the workpiece. The rubber sleeve 810 is fitted onto the surface of the fourth damping rod 803 and the fourth spring 804, thus preventing debris from getting stuck inside the fourth spring 804.

[0035] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
