Description

Technical Field

[0001] This utility model relates to the technical field of Zisha teapot processing tools, specifically to an angle-adjustable scraper holder for trimming Zisha teapots. Background Technology

[0002] In the process of making Yixing teapots, trimming the clay body (i.e., scraping and shaping the rim, shoulder, saucer, handle, spout, etc.) is a process that demands high precision, angle, and feel. Traditional hand trimming relies heavily on the craftsman holding a scraper and adjusting the angle of the tool using wrist and arm movements based on experience. However, hand trimming has the following shortcomings:

[0003] First, the shapes of Yixing teapots are complex, and different parts (such as the spout, shoulder, body, and base) require scrapers to cut at different angles. Craftsmen need to frequently adjust their wrist posture, which is not only tedious but also causes hand fatigue from holding the scraper for extended periods while maintaining a stable angle and pressure. Furthermore, during scraping, moist Yixing clay accumulates on the scraper head, and excessive accumulation can affect the smoothness and precision of the scraping. Craftsmen must frequently stop to clean the scraper head with damp cloths or other tools, which is inconvenient. In addition, trimming requires various shapes of scraper heads, which are easily lost if left lying around on the workbench.

[0004] Therefore, there is an urgent need to design an auxiliary support that can stably hold the scraper, freely adjust the angle, improve ease of use, and solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an angle-adjustable scraper holder for trimming purple clay teapots. This holder can stably hold the scraper, realize a wide range and multiple degrees of freedom adjustment of the scraper's angle and position, and integrate convenient functions for cleaning clay with the scraper head, assisting in observation, and storing the scraper head.

[0006] The technical solution adopted by this utility model to solve the above problems is: an angle-adjustable scraper bracket for trimming purple clay teapots, including a base, a connecting seat, a first swing arm and a second swing arm. The base is hinged to the first swing arm through the connecting seat, so that the first swing arm swings relative to the connecting seat. The first swing arm is slidably hinged to the second swing arm through the hinge seat, and the hinge seat can slide along the length direction of the first swing arm. At the same time, the second swing arm can slide relative to the hinge seat along its own length direction. A blade head is detachably connected to the end of the second swing arm, and a scraper sleeve for scraping off the clay from the blade head is slidably sleeved on it. The scraper sleeve has a scraping hole adapted to the blade head, and scraper strips are provided on both sides of the scraping hole.

[0007] Preferably, the first swing arm has a first sliding groove, the second swing arm has a second sliding groove, and the hinge seat includes a pin and a threaded sleeve. Two sliders are respectively fitted on the pin and are slidably adapted to the first and second sliding grooves. The hinge seat is slidably connected to the first swing arm through the sliders and can slide along its length direction. The second swing arm is hinged to the first swing arm through the same hinge seat and can slide relative to the hinge seat along its own length direction. The threaded sleeve is screwed and adapted to the pin. After tightening, the two sliders can be pressed against the inner walls of the first and second sliding grooves respectively to fix the position of the hinge seat.

[0008] Preferably, the end of the second swing arm is provided with a first slot adapted to the insertion of the cutter head, and a first locking bolt for fixing the cutter head is screwed perpendicular to the first slot.

[0009] Preferably, the second swing arm has a mounting base vertically arranged on its end side, the mounting base has a second slot, the second slot is inserted into a movable frame and fixed in position by a second locking bolt, and the end of the movable frame is damped and hinged to a magnifying glass.

[0010] Preferably, the scraper sleeve is provided with two sets of paddles symmetrically arranged on its upper and lower sides for driving it to move outward along the second swing arm, and a return spring is provided between the scraper sleeve and the mounting base for pulling it inward.

[0011] Preferably, the base has a through hole, and the bottom of the connecting seat is provided with a stud. The stud passes through the through hole and is tightened and fixed by a nut.

[0012] Preferably, the base is also magnetically fitted with a storage box for storing the blade, the storage box is provided with a compartment, the bottom of the compartment is provided with a ramp, and the storage box is also fitted with a lid via a hinge.

[0013] Compared with the prior art, this utility model has the following advantages and effects:

[0014] This invention provides multiple degrees of freedom for adjusting the blade head through the swinging of the first swing arm relative to the base, the sliding of the hinge seat along the first swing arm, the sliding of the second swing arm along itself, and the hinge of the two swing arms. The multi-degree-of-freedom robotic arm structure allows the blade head to be positioned at the required location and scraping angle for teapot trimming, solving the problem of traditional handheld operation which struggles to maintain stable angles over extended periods. The hinge seat employs a single-point locking design; tightening the screw sleeve simultaneously fixes the position of the hinge seat on the first swing arm, the position of the second swing arm within the hinge seat, and the relative angle between the two swing arms. This design greatly simplifies the adjustment process, making operation quick and reliable, providing stable support for the trimming process, and overcoming the fatigue and shaking issues associated with handheld operation. This invention also includes a scraping sleeve on the second swing arm; through scraping holes and scraping strips, clay on the blade head can be quickly scraped away, making operation convenient.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0024] Example:

[0025] See Figure 1 - Figure 7 In this embodiment, an adjustable scraper bracket for trimming purple clay teapots is provided, specifically for providing an adjustable and stable support for the trimming scraper during the teapot making process.

[0026] Specifically, in this embodiment, the support includes a base 1, a connecting seat 2, a first swing arm 3, and a second swing arm 4. The base 1 is used to stably place or fix it on the workbench. The connecting seat 2 is mounted on the base 1 and hinged to the root of the first swing arm 3, which allows the first swing arm 3 to swing left and right relative to the connecting seat 2 in the vertical plane.

[0027] The first swing arm 3 and the second swing arm 4 are connected by a hinged joint 5, and this connection method has three degrees of freedom:

[0028] (1) The hinge seat 5 slides along the length of the first swing arm 3: it can adjust the overall left and right position (or height, depending on the posture of the first swing arm 3) of the cutter head 6 to get closer to or away from the purple clay teapot body.

[0029] (2) The second swing arm 4 slides relative to the hinge seat 5 along its own length direction: adjust the extension length of the cutter head 6, i.e. the working radius.

[0030] (3) The first swing arm 3 and the second swing arm 4 rotate relative to each other through the hinge seat 5 (hinged): adjust the pitch angle of the second swing arm 4 (i.e. the cutter head 6).

[0031] Through these three degrees of freedom, and in conjunction with the swing of the first swing arm 3 relative to the base 1, this invention allows for adjustment of the position and angle of the cutter head 6. This solves the fatigue problem mentioned in the background art, where craftsmen need to frequently change their wrist posture and maintain stability for extended periods to adapt to different parts such as the spout and shoulder of the pot. The operator only needs to adjust the cutter head 6 to the desired position and angle, and the support will stably maintain that posture, effectively reducing hand fatigue and improving stability during the shaping process.

[0032] The end of the second swing arm 4 is used for detachable connection of the cutter head 6. A scraper sleeve 7 is slidably fitted onto the second swing arm 4 near the cutter head 6. The scraper sleeve 7 has a scraping hole 71, the shape and size of which are adapted to the cross-section of the cutter head 6 (for example, if the cutter head 6 is a flat plate, the scraping hole 71 is a narrow slit). Scraping strips 72 (protruding edges) are provided on both sides of the scraping hole 71 to enhance the scraping effect.

[0033] The specific steps of using this utility model are as follows: The craftsman fixes the bracket on the workbench. Based on the area to be repaired (e.g., the spout), a cutter head 6 of the desired shape is installed at the end of the second swing arm 4. The hinge seat 5 is loosened (the specific locking method is detailed in the preferred embodiment). Through the aforementioned multiple degrees of freedom, the first swing arm 3 and the second swing arm 4 are adjusted to suitable positions and angles, so that the blade of the cutter head 6 is aligned with the scraping line of the clay body. The connecting seat 2 and the hinge seat 5 are locked (using threaded fasteners) to fix the position and angle of the cutter head 6. The clay body of the purple clay teapot (usually on a turntable) is supported, rotated, and brought into contact with the fixed cutter head 6 for stable and uniform scraping. During the scraping process (e.g., after the spout is repaired), when clay accumulates on the cutter head 6 (a large amount affects accuracy), simply push the scraper sleeve 7 by hand to slide it along the second swing arm 4 towards the cutter head 6 (the cutter head 6 needs to be moved away from the spout of the clay body). Drive the scraper sleeve 7 forward so that the scraper hole 71 and scraper strip 72 sweep across the surface of the cutter head 6, scraping away the accumulated clay from the surface of the cutter head 6 (collected by an additional collector). Then, reset the scraper sleeve 7 to continue trimming the blank (such as the shoulder of the pot).

[0034] In this embodiment, the first swing arm 3 has a first sliding groove 31, and the second swing arm 4 has a second sliding groove 41. See [reference needed] Figure 3 The hinge seat 5 includes a pin 51 and a threaded sleeve 52. Two sliders 53 are sleeved on the pin 51, which are respectively adapted to slide in the first slide groove 31 and the second slide groove 41. The hinge seat 5 is slidably connected to the first swing arm 3 through the sliders 53 and can slide along its length direction. The second swing arm 4 is hinged to the first swing arm 3 through the same hinge seat 5 and can slide relative to the hinge seat 5 along its own length direction. The threaded sleeve 52 is threaded to the pin 51. After tightening, the first swing arm 3 is pressed and fitted together. At the same time, the two sliders 53 can be pressed against the inner walls of the first slide groove 31 and the second slide groove 41 respectively. The static friction generated by the compression fixes the position of the hinge seat 5, thereby locking the position of the hinge seat 5 along the first swing arm 3, the position of the second swing arm 4 along the hinge seat 5, and the relative angle between the first swing arm 3 and the second swing arm 4.

[0035] See Figure 2 and Figure 4In this embodiment, to facilitate the installation of the cutter head 6, the end of the second swing arm 4 is provided with a first slot 42 adapted to the cutter head 6, and a first locking bolt 43 for fixing the cutter head 6 is screwed perpendicularly to the first slot 42. When the cutter needs to be installed, its shank is inserted into the first slot 42 and the first locking bolt 43 is tightened. The operation is reversed when replacing. This structure is simple and reliable, making it easy for process engineers to quickly replace various cutter heads 6 of different shapes. At the same time, to assist in fine observation, a mounting base 44 is vertically provided on the side of the end of the second swing arm 4. The mounting base 44 has a second slot 45, into which a movable frame 8 is inserted and fixed in position by a second locking bolt 46. A magnifying glass 9 is damped and hinged at the end of the movable frame 8. This structure integrates the magnifying glass 9 assembly near the cutter head 6. The damping hinge allows for angle adjustment of the magnifying glass 9 and stable suspension in this position, which facilitates close observation of the fine effect of blank trimming by process engineers and facilitates more precise tool setting (setting the position and angle of the cutter head 6). Furthermore, to optimize the user experience of the scraper sleeve 7, two sets of paddles 73 are symmetrically arranged on the upper and lower sides of the scraper sleeve 7 to drive it outward along the second swing arm 4, and a return spring 74 is provided between the scraper sleeve 7 and the mounting base 44 to pull it inward. When mud removal is required, the technician squeezes the paddles 73 and drives the scraper sleeve 7 to overcome the tension of the return spring 74 and move forward to complete the mud removal. After releasing the hand, the return spring 74 automatically pulls the scraper sleeve 7 back to its original position, making the mud removal operation more convenient and smooth.

[0036] See Figure 5 In this embodiment, to achieve stable installation of the bracket, the base 1 has a through hole 11. The upper end of the connecting seat 2 is dampedly hinged to the lower end of the first swing arm 3 via a threaded fastener. A stud 21 is provided at the bottom of the connecting seat 2. The stud 21 passes through the through hole 11 and is tightened and fixed by a nut 13. The base 1 can be made of a metal material with high density, such as stainless steel, which can be attracted by a magnet. This makes the base 1 heavier, lowers the center of gravity of the bracket, and makes it more stable when placed on a table.

[0037] See Figure 6 and Figure 7 In this embodiment, to solve the problem of storing the blade head 6, the base 1 is also magnetically fitted with a storage box 12 for storing the blade head 6. The storage box 12 is provided with a compartmentalized slot 121, and the bottom of the compartmentalized slot 121 is provided with a ramp 122. The storage box 12 is also connected to a lid 123 via a hinge. The storage box 12 has a square structure, and magnets are provided around its perimeter to magnetically attract it to the outer wall of the base 1. The magnetic attraction allows the storage box 12 to be flexibly attached to a convenient position on the base 1, and it is also easy to remove. The compartmentalized slot 121 facilitates the classified storage of the blade head 6. The ramp 122 at the bottom is ergonomically designed, with one side of the bottom of the slot higher than the other, so that the blade head 6 is in an inclined state when stored, making it easy for fingers to reach in and pinch it.

[0038] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
