Description

Technical Field

[0001] The present application relates to the field of metal parts processing, and in particular to a shuttle pressing mechanism. Background Art

[0002] The shuttle refers to the metal part that passes the thread from the top to the bottom when the sewing machine is running, thus forming a stitch on the fabric.

[0003] In the prior art, the shuttle is generally hollow, with one end having a larger diameter and the other end having a smaller diameter. The shuttle is generally provided with a mounting hole for mounting the shuttle on a sewing machine. The mounting hole is generally firstly opened to a rough size, and then the mounting hole is finely processed by a reamer to meet production specifications. When the shuttle is reamed by a reamer, it is generally necessary to clamp the shuttle on the machine tool by a clamping mechanism. The existing clamping mechanism generally clamps the circumferential side of the shuttle, and the reamer moves from both ends of the shuttle along the length direction of the shuttle for processing.

[0004] The shuttle is small in size and has a relatively smooth surface. After the shuttle is clamped by the existing clamping mechanism, the shuttle is easily slipped on the clamping mechanism when being ground by a reamer, resulting in a situation where the mounting hole does not meet the specifications. Utility Model Content

[0005] In order to improve the stability of the clamping mechanism and reduce the slippage of the shuttle, the present application provides a shuttle clamping mechanism.

[0006] A shuttle clamping mechanism comprises a base, support columns are symmetrically arranged on the base, a fixed block is arranged on the side of the support column away from the base, a placement groove is provided on the fixed block for inserting one end of the shuttle, sliding rods are symmetrically arranged on the fixed block, a penetration hole is provided on the fixed block for the sliding rod to pass through and slide, a clamping plate for clamping the shuttle is provided on the end of the sliding rod away from the base, and through holes for the reamer to pass through are correspondingly provided on the clamping plate and the fixed block.

[0007] By adopting the above technical solution, the pressing plate slides in the height direction of the base through the sliding rod, and the shuttle is placed between the fixed block and the pressing plate. The pressing plate and the fixed plate cooperate to press the shuttle, so that the moving direction of the reamer is parallel to the pressing direction, thereby reducing the slippage of the shuttle. The reamer enters the pressing mechanism through the through opening and then grinds the shuttle, thereby improving the stability of the use of the pressing mechanism.

[0008] Preferably, a pressing block for pressing the shuttle is provided on one side of the pressing plate close to the fixed block, and the through opening is opened on the pressing block.

[0009] By adopting the above technical solution, the shuttle is hollow and the area of ​​one side of the shuttle is smaller, resulting in a smaller contact area between one side of the shuttle and the clamping mechanism. The clamping block is inserted into the hollow part of the shuttle to increase the contact area between the shuttle and the clamping mechanism, thereby reducing the slippage of the shuttle and improving the stability of the clamping plate.

[0010] Preferably, a driving plate is provided at one end of the sliding rod close to the base, a pressure plate is provided at one side of the fixed block close to the driving plate, a retreat groove is bent on the pressure plate for the reamer to drill into, and a cylinder for pressing the pressure plate is provided at one side of the driving plate close to the pressure plate.

[0011] By adopting the above technical solution, the cylinder presses the pressing plate, thereby driving the driving plate close to the base, and then driving the pressing plate and the pressing block to press the shuttle, thereby reducing the situation where the shuttle is detached from the pressing mechanism and improving the stability of the pressing block.

[0012] Preferably, a mounting tube is provided between the fixing block and the sliding rod, and the penetration hole is used for the mounting tube to penetrate and be installed.

[0013] By adopting the above technical solution, the sliding rod slides in the penetration hole, thereby reducing the wear between the sliding rod and the clamping plate. The pressing length between the sliding rod and the clamping plate is increased by installing the tube, thereby reducing the displacement of the sliding rod on the clamping plate, thereby improving the stability of the sliding rod.

[0014] Preferably, a compression spring for driving the clamping plate to press toward a side away from the base is provided on the installation tube, a compression spring groove for installing the compression spring is provided on the installation tube, and the compression spring is sleeved on the sliding rod.

[0015] By adopting the above technical solution, one end of the compression spring presses against the bottom of the compression spring groove, and the other end of the compression spring presses against the clamping plate, thereby driving the clamping plate to slide to the side away from the base, entering a state in which the clamping plate remains separated from the fixed block, making it easier to install the shuttle and improving the ease of use of the clamping mechanism.

[0016] Preferably, a protective cover is provided on the fixing block, the mounting groove is for inserting and installing the protective cover, and the protective cover is used to carry the shuttle.

[0017] By adopting the above technical solution, the shuttle is supported by the protective cover, thereby reducing the situation where the pressing block presses the shuttle against the fixed block to damage the fixed block, and reducing the situation where the fixed block is damaged when the reamer grinds the shuttle, thereby improving the stability of the fixed block in use.

[0018] Preferably, a pressing block for pressing and fixing the protective sleeve and the mounting tube is provided on one side of the fixing block close to the protective sleeve.

[0019] By adopting the above technical solution, the pressing block cooperates with the fixing block to press and fix the protective sleeve and the installation sleeve on the fixing block, thereby reducing the situation where the protective sleeve and the installation sleeve are separated from the fixing block and improving the installation stability of the protective sleeve and the installation sleeve.

[0020] Preferably, the support column is arranged in a trapezoidal shape, a limiting block is arranged on a side of the base close to the support column, and a limiting groove is provided on the limiting block for the support column to be inserted and installed.

[0021] By adopting the above technical solution, the support column is vertically arranged on the base. When the support column is subjected to a force in the horizontal direction relative to the base, the support column is pressed against the limit block in the limit groove, thereby driving the limit block to press against the base, thereby reducing the deviation of the support column on the base, thereby improving the stability of the support column installation.

[0022] Preferably, a protrusion is provided on one side of the limit block close to the support column, and a groove for installing the protrusion is provided on the support column.

[0023] By adopting the above technical solution, the protrusion is pressed against the support column in the groove, thereby reducing the slippage between the limit block and the support column, thereby reducing the limit block from escaping from the clamping mechanism, and further improving the stability of the limit block installation.

[0024] Preferably, the support column is symmetrically provided with snap-fit ​​strips on both sides close to the limiting block, and the limiting block is provided with snap-fit ​​grooves for the snap-fit ​​strips to be snap-fitted and fixed.

[0025] By adopting the above technical solution, the clamping strip presses against the limit block in the clamping groove, thereby reducing the slippage between the limit block and the support column, thereby reducing the limit block from escaping from the clamping mechanism, and further improving the stability of the limit block installation.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The pressing plate slides in the height direction of the base through the sliding rod, and the shuttle is placed between the fixed block and the pressing plate. The pressing plate and the fixed plate cooperate to press the shuttle, thereby increasing the contact area between the shuttle and the pressing mechanism to increase the friction between the shuttle and the pressing mechanism, thereby reducing the slippage of the shuttle;

[0028] 2. The shuttle is hollow, and one side of the shuttle has a smaller area, which results in a smaller contact area between one side of the shuttle and the clamping mechanism. A clamping block is inserted into the hollow part of the shuttle to increase the contact area between the shuttle and the clamping mechanism, thereby reducing the slippage of the shuttle;

[0029] 3. The cylinder presses the pressing plate, thereby driving the driving plate close to the base, and then driving the pressing plate and the pressing block to press the shuttle, thereby reducing the situation where the shuttle is separated from the pressing mechanism.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a shuttle clamping mechanism, including a base 1, a support column 2, a fixed block 3, a sliding rod 4 and a clamping plate 5. The support columns 2 are symmetrically arranged on both sides of the base 1, and the support columns 2 and the base 1 are connected by bolts. The fixed block 3 is arranged on the side of the support column 2 away from the base 1, and a mounting groove 23 for mounting the fixed block 3 is provided on the support column 2. The fixed block 3 is pressed against the support column 2 in the mounting groove 23 to reduce the sliding of the fixed block 3 on the support column 2. A placement groove 31 is provided on the fixed block 3 for inserting one end of the shuttle 7 into a limited position. The sliding rod 4 is slidably connected to the fixed block 3, and a penetration hole 32 is provided on the fixed block 3 for the sliding rod 4 to penetrate and slide. The clamping plate 5 is fixed to the end of the sliding rod 4 away from the base 1 by bolts. The pressing plate 5 slides in the height direction of the base 1 through the sliding rod 4 , so that the pressing plate 5 presses against the fixing block 3 to clamp the shuttle 7 , and the reamer enters the pressing mechanism through the through opening 51 and grinds the shuttle 7 .

[0037] Reference Figure 1 and Figure 2The end of the sliding rod 4 close to the base 1 is fixed with a driving plate 6 by bolts, and the side of the driving plate 6 close to the fixed block 3 is provided with a cylinder 61 for driving the driving plate 6 to slide toward the side close to the base 1. The side of the fixed block 3 close to the base 1 is fixed with a pressing piece 33 pressed by the cylinder 61 by bolts, and the pressing piece 33 is bent on the fixed block 3 to form a retreat groove 34 for the reamer to enter. When the shuttle 7 needs to be clamped, the pressing piece 33 is pressed by the cylinder 61 to make the driving plate 6 slide toward the direction close to the base 1, thereby driving the pressing plate 5 to press toward the side close to the fixed block 3, thereby reducing the situation where the shuttle 7 is separated from the pressing device.

[0038] Reference Figure 1 and Figure 2 A mounting tube 35 is provided on the side of the fixed block 3 close to the pressing plate 5. The mounting tube 35 is inserted and installed in the through hole 32. The sliding rod 4 slides in the mounting tube 35 to reduce the wear of the sliding rod 4 and the fixed block 3. A compression spring 36 is provided in the mounting tube 35 for driving the pressing plate 5 to slide to the side away from the base 1. The compression spring 36 is sleeved on the sliding rod 4. A compression spring groove 351 for installing the compression spring 36 is provided on the mounting tube 35. One end of the compression spring 36 presses against the bottom of the compression spring groove 351, and the other end of the compression spring 36 presses against the pressing plate 5. The compression spring 36 is used to keep the pressing plate 5 away from the fixed block 3, so as to facilitate the placement of the shuttle 7.

[0039] Reference Figure 2 and Figure 3 A protective cover 37 is provided on one side of the fixed block 3 close to the pressing plate 5. The protective cover 37 is inserted and installed in the mounting groove 31. One end of the shuttle 7 is inserted into the protective cover 37. The protective cover 37 reduces the possibility of damage to the fixed block 3 when the pressing plate 5 presses the shuttle 7 against the fixed block 3.

[0040] Reference Figure 2 and Figure 3 The shuttle 7 is hollow, and a clamping block 52 is fixed to the side of the clamping plate 5 close to the fixing block 3 by bolts. The clamping block 52 is inserted into the cavity of the shuttle 7 and cooperates with the protective cover 37 to clamp the relatively flat side of the shuttle 7, thereby improving the clamping effect of the clamping mechanism on the shuttle 7.

[0041] Reference Figure 3 and Figure 4 A pressing block 38 is fixed to the side of the fixing block 3 away from the base 1 by bolts. The pressing block 38 presses against the protective sleeve 37 and the mounting tube 35 respectively, thereby pressing and fixing the protective sleeve 37 and the mounting sleeve on the fixing block 3.

[0042] Reference Figure 3 and Figure 4The side of the base 1 close to the support column 2 is fixed with a limit block 11 by bolts, and a limit slot 111 is provided on the limit block 11 for the support column 2 to be inserted, and the support column 2 is arranged in a trapezoidal shape. When the support column 2 is subjected to a force parallel to the base 1, the support column 2 presses against the limit block 11 in the limit slot 111, thereby driving the limit block 11 to press against the base 1, thereby reducing the deviation of the support column 2.

[0043] Reference Figure 3 and Figure 4 The side of the limit block 11 close to the support column 2 is integrally provided with a protrusion 112, and the support column 2 is provided with a groove 21 for installing the protrusion 112. The side of the support column 2 close to the limit block 11 is integrally provided with a clamping strip 22, and the clamping strip 22 is symmetrically arranged on both sides of the support column 2, and the limit block 11 is provided with a clamping groove 113 for installing the clamping strip 22. Through the cooperation between the protrusion 112 and the groove 21, and the cooperation between the clamping strip 22 and the clamping groove 113, the connection strength between the limit block 11 and the support column 2 is improved, thereby improving the connection strength between the support column 2 and the base 1.

[0044] Working process:

[0045] 1. Insert the end of the shuttle 7 with a smaller diameter into the protective cover 37, and then the end of the shuttle 7 with a larger diameter presses against the protective cover 37 to fix the shuttle 7 on the protective cover 37;

[0046] 2. The piston rod of the cylinder 61 extends and presses against the pressing plate 33. At this time, the driving plate 6 slides toward the side close to the base 1, thereby driving the sliding rod 4 and the pressing plate 5 to slide toward the side close to the base 1, and then driving the pressing block 52 to cooperate with the protective cover 37 to press the shuttle 7, and the compression spring 36 is deformed;

[0047] 3. The reamer enters the clamping mechanism from the opening 51 and grinds the shuttle 7, and then exits the clamping mechanism from the opening 51;

[0048] 4.
