Description

Technical Field

[0001] This utility model belongs to the technical field of pilot head processing equipment, specifically relating to a fixed-length cutting device for processing pilot head copper sleeves. Background Technology

[0002] In the pneumatic field, the pilot head is one of the core components of a solenoid valve. The main structure of the pilot head includes a copper sleeve, a stationary iron core, a moving iron core, a coil assembly, and a moving iron core spring. The copper sleeve is fixedly connected to the valve seat of the solenoid valve. The stationary iron core is fixedly housed inside the copper sleeve, while the moving iron core is movably housed inside the copper sleeve. The coil assembly is fixedly sleeved outside the copper sleeve, and the moving iron core spring is housed inside the copper sleeve and engages with the moving iron core. By controlling the energization of the coil assembly, the moving iron core can be activated accordingly, thereby controlling the opening and closing of the solenoid valve or switching the fluid flow path.

[0003] Copper sleeves (also known as magnetic shielding tubes) are constructed using specific materials (such as stainless steel, nickel-based alloys, or non-magnetic composite materials) to create a magnetic reluctance barrier, achieving directional magnetic field conduction and interference isolation. During the production and processing of copper sleeves, fixed-length cutting is typically required using a cutting device. Currently, existing fixed-length cutting equipment for pilot head copper sleeve processing mostly uses mechanical limit blocks or pneumatic clamps to position the copper sleeve workpiece to be cut. Due to metal fatigue and thermal deformation, the positioning error increases linearly with usage time, leading to reduced processing accuracy and affecting product qualification rates.

[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0023] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fixed-length cutting device for processing copper sleeves with a pilot head includes a worktable 1, a cutting platform 2 on the worktable 1, a cutting assembly 3 above the cutting platform 2, a fixing mechanism 4 for fixing and clamping the material tube on one side of the cutting platform 2, a fixed-length mechanism 5 for adjusting the cutting length of the material tube on the other side of the cutting platform 2, and a collecting mechanism 6 below the cutting platform 2.

[0024] This utility model proposes a fixed-length cutting device for processing copper sleeves with a pilot head. The worktable 1 serves as the basic support structure of the entire device, playing a role in bearing and stabilizing, ensuring that the relative positions of each component remain unchanged during operation. The cutting platform 2 is set on the worktable 1 and is the main working area for cutting copper sleeves. The cutting platform 2 provides suitable installation and operating space for the cutting assembly 3, the fixing mechanism 4, the fixed-length mechanism 5, and the tube to be cut.

[0025] The cutting assembly 3 is installed above the cutting platform 2 and is used to cut the copper sleeve material placed on the cutting platform 2. The fixing mechanism 4 is located on one side of the cutting platform 2, and its main function is to fix and clamp the copper sleeve material placed on the cutting platform 2. The fixing mechanism 4 ensures that the material remains stable during the cutting process and does not move or shake, thereby ensuring the accuracy and quality of the cutting.

[0026] The length-fixing mechanism 5 is located on the other side of the cutting platform 2 and is used to adjust the cutting length of the copper sleeve tube. By adjusting the position of the positioning baffle, the length-fixing mechanism 5 can determine the cutting length of the tube to meet the processing requirements of copper sleeves with different lengths. The collection mechanism 6 is installed below the cutting platform 2 and is mainly used to collect copper sleeve waste and finished products generated during the cutting process. The collection mechanism 6 collects the cut waste and finished products in a timely manner, maintaining a clean working environment, and also facilitating the recycling of waste and subsequent processing of finished products.

[0027] First, place the copper sleeve to be cut on the cutting platform 2, aligning one end with the positioning baffle of the length-fixing mechanism 5. Determine the cutting point of the sleeve by adjusting the position of the positioning baffle of the length-fixing mechanism 5 according to the required cutting length. Then, operate the fixing mechanism 4 to firmly clamp the sleeve, ensuring it does not move during the cutting process.

[0028] The cutting assembly 3 is activated, and the power unit in the cutting assembly 3 drives the cutting tool to move downwards, cutting the copper sleeve material tube fixed on the cutting platform 2. During the cutting process, the cutting tool cuts according to preset cutting parameters (such as cutting speed, cutting depth, etc.) to ensure the flatness and perpendicularity of the cut surface.

[0029] After cutting, the cut copper sleeve finished product and waste material will fall into the collection mechanism 6 below the cutting platform 2. The collection mechanism 6 collects the finished product and waste material separately. The finished product can be further processed and treated, while the waste material can be recycled and reused to improve material utilization and reduce production costs.

[0030] After completing one cut, if you need to continue cutting copper sleeves of the same or different lengths, simply repeat the above steps, adjust the position of the positioning baffle of the length fixing mechanism 5 (if the cutting length needs to be changed), reinstall and fix the material tube, and then start the cutting assembly 3 again to cut.

[0031] This fixed-length cutting device for pilot head copper sleeve processing can achieve precise fixed-length cutting of copper sleeve material, improve cutting efficiency and cutting quality, and meet the production needs of pilot head copper sleeve processing.

[0032] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the length-fixing mechanism 5 includes a fixed frame 51 set on one side of the cutting platform 2. The fixed frame 51 is provided with a threaded hole 52. A threaded rod 53 is threadedly connected to the threaded hole 52. One end of the threaded rod 53 is connected to a positioning push plate 54, and the other end of the threaded rod 53 is connected to a handwheel 55.

[0033] Specifically, the mounting bracket 51 is located on one side of the cutting platform 2. The mounting bracket 51 provides a position for mounting and securing other components, ensuring the stability and reliability of the entire length-fixing mechanism 5 during operation. A threaded hole 52, formed on the mounting bracket 51, is a hole with a specific internal thread. The specifications of the threaded hole 52 match those of the threaded rod 53, providing a precise threaded connection position for the threaded rod 53, ensuring that the threaded rod 53 can rotate smoothly and achieve linear movement within it.

[0034] The threaded rod 53 is the core transmission component of the fixed-length mechanism 5, and its outer surface has an external thread that matches the internal thread of the threaded hole 52. One end of the threaded rod 53 is connected to the positioning push plate 54, and the other end is connected to the handwheel 55. By rotating the threaded rod 53, the rotational motion is converted into linear motion using the transmission principle of the thread, thereby driving the positioning push plate 54 to move.

[0035] The positioning push plate 54 is connected to one end of the threaded rod 53. Its function is to contact the copper sleeve to be cut and provide a positioning reference for the sleeve. The surface of the positioning push plate 54 is usually designed to be flat and smooth to ensure accurate and stable positioning when in contact with the sleeve and to avoid damaging the surface of the sleeve.

[0036] The handwheel 55 is mounted on the other end of the threaded rod 53 and is the part that allows the operator to manually rotate the threaded rod 53. The handwheel 55 is designed to be easy for the operator to hold and apply force. By turning the handwheel 55, the rotation of the threaded rod 53 can be easily controlled, thereby adjusting the position of the positioning push plate 54.

[0037] Before the cutting operation is performed, the initial position of the positioning push plate 54 is determined according to the required length of the copper sleeve to be cut. At this time, the operator can roughly determine the position of the positioning push plate 54 based on the scale markings on the cutting platform 2 (if any) or the pre-set size parameters.

[0038] The operator holds and rotates the handwheel 55. Since the handwheel 55 is connected to the threaded rod 53, rotating the handwheel 55 causes the threaded rod 53 to rotate within the threaded hole 52 of the mounting bracket 51. Due to the characteristics of threaded transmission, when the threaded rod 53 rotates, it moves linearly along the axis of the threaded hole 52. If the handwheel 55 is rotated clockwise, the threaded rod 53 moves closer to the cutting platform 2, thereby pushing the positioning push plate 54 closer to the material tube; if the handwheel 55 is rotated counterclockwise, the threaded rod 53 moves away from the cutting platform 2, causing the positioning push plate 54 away from the material tube.

[0039] The operator continuously rotates the handwheel 55 until the positioning push plate 54 is in close contact with one end of the copper sleeve to be cut, and the other end of the sleeve reaches the required cutting length. At this point, the positioning push plate 54 provides precise positioning for the sleeve, ensuring that the cutting length of the sleeve remains consistent each time it is cut.

[0040] After positioning is completed, the cutting component 3 of the cutting device is activated to cut the copper sleeve tube fixed on the cutting platform 2 and positioned at one end by the positioning push plate 54. After cutting, if it is necessary to cut tubes of different or the same length again, simply repeat the above positioning adjustment steps and re-determine the position of the positioning push plate 54.

[0041] The length-fixing mechanism 5 allows for convenient and accurate adjustment of the cutting length of the copper sleeve material, improving cutting precision and consistency, and meeting the production requirements of pilot head copper sleeve processing.

[0042] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a lead screw 7 is connected between the cutting platform 2 and the fixed frame 51, and an opening 541 matching the lead screw 7 is provided on the positioning push plate 54.

[0043] Specifically, the fixing frame 51 is set on one side of the cutting platform 2, providing a support structure for the installation and fixing of components such as the lead screw 7 and the threaded rod 53, so that the entire length-fixing mechanism 5 can work stably.

[0044] The lead screw 7 connects the cutting platform 2 and the fixed frame 51. The lead screw 7 is a mechanical transmission element that converts rotary motion into linear motion, and it has a certain length and a helical groove structure. One end of the lead screw 7 is fixed to the cutting platform 2, and the other end is fixed to the fixed frame 51.

[0045] The positioning push plate 54 is used to position the copper sleeve tube to determine the cutting length. The positioning push plate 54 is provided with an opening 541 that matches the lead screw 7. The shape and size of this opening 541 are adapted to the outer diameter and spiral groove of the lead screw 7, so that the positioning push plate 54 can move linearly along the lead screw 7.

[0046] During device installation, securely connect both ends of the lead screw 7 to the cutting platform 2 and the fixing frame 51 respectively, ensuring that the lead screw 7 is horizontal. Fit the positioning push plate 54 onto the lead screw 7 through its opening 541, allowing the positioning push plate 54 to slide along the lead screw 7. Simultaneously, install the threaded rod 53 in the threaded hole 52 of the fixing frame 51, and install the handwheel 55 at one end of the threaded rod 53. The positioning push plate 54 is connected to the other end of the threaded rod 53.

[0047] When adjusting the cutting length of the copper sleeve tube, the operator turns the handwheel 55, which in turn rotates the threaded rod 53 in the threaded hole 52 of the fixed frame 51. Since the threaded rod 53 is connected to the positioning push plate 54, according to the principle of threaded transmission, the rotation of the threaded rod 53 will cause the positioning push plate 54 to move along the axis of the threaded rod 53. At the same time, the positioning push plate 54 is fitted onto the lead screw 7 through the opening 541. Under the constraint of the lead screw 7, the positioning push plate 54 can only move in a straight line along the lead screw 7. In this way, by rotating the handwheel 55, the position of the positioning push plate 54 on the lead screw 7 can be controlled.

[0048] According to the scale markings on the cutting platform 2 or the preset size parameters, the operator continuously rotates the handwheel 55 until the positioning push plate 54 moves to the required position, so that one end of the copper sleeve material tube placed on the cutting platform 2 contacts the positioning push plate 54. At this time, the distance from the other end of the material tube to the cutting position is the required cutting length.

[0049] After adjusting the position of the positioning push plate 54, start the cutting assembly 3 of the cutting device to cut the copper sleeve tube fixed on the cutting platform 2 and positioned at one end by the positioning push plate 54. After cutting, if it is necessary to cut tubes of different or the same length again, simply repeat the above steps of adjusting the position of the positioning push plate 54 and redetermine the cutting length.

[0050] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a scale is provided on the outer periphery of the lead screw 7.

[0051] Specifically, the scale is located on the outer circumference of the lead screw 7. The scale is evenly distributed, and the scale value is set according to actual needs, possibly in millimeters (mm). It is used to accurately indicate the moving distance of the positioning push plate 54 on the lead screw 7, which is the adjustment length of the copper sleeve tube. The design of the scale makes it easy for operators to intuitively read the position information of the positioning push plate 54.

[0052] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the cutting assembly 3 includes a mounting frame 31 mounted on the workbench 1. A first motor 32 is mounted on the mounting frame 31. A sliding block 33 is connected to the output end of the first motor 32. A second motor 34 is mounted on the sliding block 33. A cutting machine 35 is connected to the output end of the second motor 34.

[0053] Specifically, the mounting frame 31 is fixedly mounted on the worktable 1 and serves as the main support structure for the cutting assembly 3. The mounting frame 31 stably supports the first motor 32 and other related components. The first motor 32, mounted on the mounting frame 31, is one of the power sources for the cutting assembly 3. The output end of the first motor 32 is connected to the sliding block 33, transmitting rotational motion to the sliding block 33. The sliding block 33, connected to the output end of the first motor 32, can perform linear motion on the mounting frame 31 under the drive of the first motor 32. The sliding block 33 is equipped with guide rails and groove structures that cooperate with the mounting frame 31 to ensure the smoothness and accuracy of its movement. Simultaneously, the sliding block 33 serves as the mounting carrier for the second motor 34, providing stable support for the second motor 34.

[0054] The second motor 34 is fixedly mounted on the sliding block 33 and serves as another power source for the cutting assembly 3. The output of the second motor 34 is connected to the cutting machine 35, driving it to perform rotary cutting operations. The cutting machine 35, connected to the output of the second motor 34, is the tool that directly cuts the copper sleeve. The cutting machine 35 typically employs high-speed rotating blades or grinding wheels, enabling it to quickly and effectively cut the copper sleeve.

[0055] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fixing mechanism 4 includes a cylinder 41 mounted on the mounting frame 31. The output end of the cylinder 41 is connected to a fixed pressure plate 42, and the bottom of the fixed pressure plate 42 is provided with a downward pressure groove that matches the outer wall of the material tube. Specifically, the cylinder 41 is fixedly mounted on the mounting frame 31 and is the power source of the fixing mechanism 4. The cylinder 41 provides power for the up-and-down movement of the fixed pressure plate 42. The fixed pressure plate 42 is connected to the output end of the cylinder 41 and can make vertical linear movements under the drive of the cylinder 41. The fixed pressure plate 42 ensures that it will not deform when clamping the material tube, can cover part of the outer wall of the material tube, and provides sufficient clamping force. The downward pressure groove is located at the bottom of the fixed pressure plate 42 and is the part that directly contacts the outer wall of the material tube. The shape of the downward pressure groove matches the outer wall of the material tube, usually a semi-circular or V-shaped groove, which can increase the contact area between the fixed pressure plate 42 and the material tube, improve the stability and reliability of clamping, and prevent the material tube from rolling or displacing during the cutting process.

[0056] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the collection mechanism 6 includes a collection frame 61 set on the workbench 1, and a removable collection box 62 is provided inside the collection frame 61.

[0057] Specifically, the collection frame 61 is fixedly mounted on the workbench 1 and forms the main frame of the collection mechanism 6. The dimensions of the collection frame 61 are designed according to actual production needs and the scale of the cutting device, ensuring it can hold a certain amount of finished products and waste. The collection box 62 is placed inside the collection frame 61 and is used directly to hold the finished products and waste. The collection box 62 is designed as a detachable structure for easy cleaning and replacement when full. The shape of the collection box 62 is adapted to the collection frame 61, generally rectangular, and its internal space is large enough to meet collection needs for a certain period of time.

[0058] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, support legs 8 are provided at the four corners of the bottom of the workbench 1. Specifically, there are four support legs 8 located at the four corners of the bottom of the workbench 1. Each support leg 8 is generally made of a cylindrical or square metal rod (such as a steel pipe or square steel), which provides good stability and load-bearing capacity. The length of the support leg 8 is determined according to the actual usage requirements and operating space, and its lower end is usually equipped with an anti-slip pad or adjustable feet.

[0059] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
