Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a fixing clamp for processing a pull rod of a textile machine. Background Art

[0002] Textile machinery, also known as textile machinery, is a general term for various mechanical equipment that processes natural fibers or chemical fibers into the required textiles. The pull rod is a sub-component in textile machinery. The pull rod is composed of a middle connecting rod and two rings. It is processed as a whole through an injection mold. However, after the injection molding is completed, there will be a raised part around the outside. Therefore, a grinder will be used to grind the surface of the pull rod after molding.

[0003] For example, the Chinese patent with publication number CN116061057B is a textile machine pull rod production and processing device. Through the grinding roller reciprocating around the axis of the lower round cover, the injection-molded protrusions on the outer wall of the special-shaped end of the pull rod can be well ground to avoid uneven and unclean grinding of the injection-molded protrusions outside the sleeve ring in the pull rod.

[0004] At present, after the textile machinery pull rod is ground, the inner holes of the two ring sleeves are drilled to meet the size requirements because high precision requirements are required for the two holes when used. During the drilling process, the traditional method is usually adopted, which requires the textile machinery pull rod to be fixed first, and then the position is adjusted by using drilling equipment, and the two ends of the textile machinery pull rod are drilled in turn. After the drilling is completed, the textile machinery pull rod is replaced and installed with a new processed textile machinery pull rod. When a large number of textile machinery pull rods need to be produced, the traditional processing method requires staff to repeatedly clamp the textile machinery pull rods, which is more troublesome and difficult to position the pull rods, resulting in a long process cycle and large cumulative errors due to repeated clamping.

[0021] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0022] See attached Figure 1-2 As shown, the fixing fixture for processing the textile machinery pull rod of the first embodiment includes a fixture body 1, and the fixture body 1 has at least a pair of workstations arranged along the length direction of the fixture body 1. The fixture body 1 corresponding to each workstation is provided with a positioning hole 2 arranged along the width direction of the fixture body 1, and each positioning hole 2 is provided with a concentric clearance hole 3. The diameter of the clearance hole 3 is 0.5 mm larger than the processing hole diameter of the textile machinery pull rod 5. The aperture of the clearance hole 3 is larger than the aperture of the textile machinery pull rod 5, so that the drilling tool will not touch the inner wall of the clearance hole 3 during processing.

[0023] The depth of the positioning hole 2 from the upper surface of the fixture body 1 is 1 mm, and the diameter of the positioning hole 2 is greater than the diameter of the clearance hole 3 .

[0024] By setting the depth of the positioning hole 2 to 1 mm, when the spinning machine pull rod 5 is placed, both ends of the spinning machine pull rod 5 can enter the interior of the positioning hole 2 for auxiliary positioning, which is convenient for the staff to identify the position of the spinning machine pull rod 5 during installation.

[0025] Each pair of workstations includes a rotating lifting mechanism, a positioning pin 4 and a pressure plate 6. The rotating lifting mechanism is arranged between two clearance holes 3 at one end along the width direction of the clamp body 1. The pressure plate 6 is slidably connected to the top of the rotating lifting mechanism. The sliding connection between the pressure plate 6 and the clamping bolt 8 allows the pressure plate 6 to slide up and down on the surface of the clamping bolt 8, or rotate around the clamping bolt 8, which is used to adjust the position of the pressure plate 6 when the textile machine pull rod 5 is placed or removed, and semicircular grooves matching the clearance holes 3 are respectively provided at both ends of the pressure plate 6. The positioning pin 4 is located on one side of the corresponding pressure plate 6, and the bottom end of the positioning pin 4 is fixedly connected to the clamp body 1. The height of the positioning pin 4 is greater than the height of the textile machine pull rod 5.

[0026] Through the setting of the positioning pin 4, when the pressure plate 6 is rotated 90° clockwise to adjust the position, the positioning pin 4 can limit the side of the pressure plate 6, so that the pressure plate 6 can maintain a horizontal state when fixing the textile machine pull rod 5. When taking out the parts, the pressure plate 6 can be rotated 90° counterclockwise so that the two ends of the pressure plate 6 are separated from the textile machine pull rod 5, which will not affect the taking out of the textile machine pull rod 5.

[0027] The rotating lifting mechanism includes a clamping bolt 8 and a clamping nut 7. The clamping bolt 8 is detachably arranged on the clamp body 1 and is located between two corresponding makeshift holes 3. An internal threaded hole corresponding to the clamping bolt 8 is opened on the clamp body 1. The surface of the clamping bolt 8 is sleeved with a support spring 81 that can provide supporting force to the pressure plate 6.

[0028] By setting the threaded connection of the clamping bolt 8, the clamping nut 7 can limit the pressure plate 6. When the clamping bolt 8 rotates and moves downward, the clamping nut 7 will drive the pressure plate 6 to move downward together, so that the pressure plate 6 is clamped downward against the upper surface of the textile machine pull rod 5.

[0029] During operation, the two textile machine pull rods 5 are placed longitudinally on both sides of the pressure plate 6, and then the two pressure plates 6 are rotated so that when the pressure plates 6 are set horizontally, the two ends of the two pressure plates 6 will fit with the processed holes on the textile machine pull rod 5 and move down through the pressure plates 6. After the pressure plates 6 are fixed by the rotating lifting mechanism, the pressure plates 6 can fix the textile machine pull rods 5. After the processing of the textile machine pull rods 5 is completed, the clamping nut 7 is twisted to make the clamping bolt 8 move upward in the threaded hole. Then, after the pressure plate 6 releases the fixation of the textile machine pull rod 5, the pressure plate 6 is rotated 90° counterclockwise at this time. The pressure plate 6 rotates to the neutral position, and the support spring 81 can support the pressure plate 6. The pressure plate 6 bounces upward, which is convenient for taking out the processed textile machine pull rod 5, while avoiding the pressure plate 6 from sinking due to gravity, resulting in the need to lift the pressure plate 6 during installation, which increases the clamping time and reduces the work efficiency.

[0030] Furthermore, every two corresponding workstations constitute a clamping component, and a plurality of clamping components are provided on the clamp body 1 .

[0031] The device can be provided with a plurality of clamping components as required. Preferably, two rows are provided on the clamp body 1, and four clamping components are provided in one row, and two columns are provided. When a plurality of clamping components are provided on the clamp body 1, the positioning holes 3 and the positioning pins 4 are provided accordingly, so that the textile machinery pull rods 5 that can be installed by the clamp are also increased accordingly. When the clamp is used in conjunction with a CNC machine tool for processing, multiple processes can be completed at one time in the machining center, and multiple products can be clamped at one time, with the efficiency increased by 200%. The product sizes are consistent, and the qualified rate has increased from the previous 96% to the current 99.8%. It can be used to replace the traditional single processing method, and solves the problem that the processing flow is long due to the traditional processing method, and when there are many textile machinery pull rods 5, repeated disassembly and installation lead to easy fixing errors and affect the processing accuracy.

[0032] See attached Figure 1-2 As shown, the fixing fixture for processing the textile machine pull rod 5 of the second embodiment includes a fixture body 1, and the fixture body 1 has at least a pair of workstations arranged along the length direction of the fixture body 1. The fixture body 1 corresponding to each workstation is provided with a positioning hole 2 arranged along the width direction of the fixture body 1, and each positioning hole 2 is provided with a concentric clearance hole 3. The diameter of the clearance hole 3 is 0.5 mm larger than the processing hole diameter of the textile machine pull rod 5. The aperture of the clearance hole 3 is larger than the aperture of the textile machine pull rod 5, so that the drilling tool will not touch the inner wall of the clearance hole 3 during processing.

[0033] A positioning hole 2 is provided on the clamp body 1 and at the top end of the clearance hole 3 . The depth of the positioning hole 2 from the upper surface of the clamp body 1 is 1 mm, and the diameter of the positioning hole 2 is greater than the diameter of the clearance hole 3 .

[0034] By setting the depth of the positioning hole 2 to 1 mm, when the spinning machine pull rod 5 is placed, both ends of the spinning machine pull rod 5 can enter the interior of the positioning hole 2 for auxiliary positioning, which is convenient for the staff to identify the position of the spinning machine pull rod 5 during installation.

[0035] Each pair of workstations includes a rotating lifting mechanism, a positioning pin 4 and a pressure plate 6. The rotating lifting mechanism is arranged between two clearance holes 3 at one end along the width direction of the clamp body 1. The pressure plate 6 is slidably connected to the top of the rotating lifting mechanism, and semicircular grooves matching the clearance holes 3 are respectively provided at both ends of the pressure plate 6. The positioning pin 4 is located on one side of the corresponding pressure plate 6, and the bottom end of the positioning pin 4 is fixedly connected to the clamp body 1.

[0036] Through the setting of the positioning pin 4, when the pressure plate 6 is rotated 90° clockwise to adjust the position, the positioning pin 4 can limit the side of the pressure plate 6, so that the pressure plate 6 can maintain a horizontal state when fixing the textile machine pull rod 5. When taking out the parts, the pressure plate 6 can be rotated 90° counterclockwise so that the two ends of the pressure plate 6 are separated from the textile machine pull rod 5, which will not affect the taking out of the textile machine pull rod 5.

[0037] The rotating lifting mechanism includes a clamping bolt 8 and a clamping nut 7. The clamping bolt 8 is detachably arranged on the clamp body 1 and is located between two corresponding makeshift holes 3. A through hole adapted for the vertical movement of the clamping bolt 8 is penetrated through the clamp body 1, and a cylinder capable of driving the clamping bolt 8 to move vertically along the through hole is arranged on the lower surface of the clamp body 1, and the output end of the cylinder is fixedly connected to the bottom end of the clamping bolt 8.

[0038] Through the setting of the cylinder, when it is necessary to remove and unload the textile machine pull rod 5, the cylinder is started, so that the cylinder pushes the clamping bolt 8 to move upward, and then the clamping bolt 8 pushes the clamping nut 7 to move upward, and releases the pressure of the clamping nut 7 on the pressure plate 6, so that the pressure plate 6 releases the fixation of the textile machine pull rod 5.

[0039] When the textile machine pull rod 5 is replaced, it is placed at the specified position on the clamp body 1, and then the cylinder is started to drive the clamping nut 7 to limit the pressure plate 6. When the clamping bolt 8 moves downward, the clamping nut 7 will drive the pressure plate 6 to move downward, so that the pressure plate 6 is clamped downward against the upper surface of the textile machine pull rod 5.

[0040] The pressure plate 6 can slide up and down on the surface of the clamping bolt 8, or be rotated with the clamping bolt 8 as the axis to move the clamping bolt 8 downward. The clamping bolt 8 will limit the pressure plate 6 through the clamping nut 7 and drive the pressure plate 6 to move downward, so that the pressure plate 6 can fix and clamp the textile machine.

[0041] After the processing of the textile machine tie rod 5 is completed, the cylinder drives the screw rod to move upward, so that the pressing plate 6 releases the fixation of the textile machine tie rod 5, and then the pressing plate 6 is rotated 90° counterclockwise to rotate the pressing plate 6 to the neutral position, so that the staff can take out the textile machine tie rod 5.

[0042] Furthermore, every two corresponding workstations constitute a clamping component, and a plurality of clamping components are provided on the clamp body 1 .

[0043] The device can be provided with a plurality of clamping components as required. Preferably, two rows are provided on the clamp body 1, and four clamping components are provided in one row, and two columns are provided. When a plurality of clamping components are provided on the clamp body 1, the positioning holes 3 and the positioning pins 4 are provided accordingly, so that the textile machinery pull rods 5 that can be installed by the clamp are also increased accordingly. When the clamp is used in conjunction with a CNC machine tool for processing, multiple processes can be completed at one time in the machining center, and multiple products can be clamped at one time, with the efficiency increased by 200%. The product sizes are consistent, and the qualified rate has increased from the previous 96% to the current 99.8%. It can be used to replace the traditional single processing method, and solves the problem that the processing flow is long due to the traditional processing method, and when there are many textile machinery pull rods 5, repeated disassembly and installation lead to easy fixing errors and affect the processing accuracy.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
