Description

Technical Field

[0001] The utility model belongs to the technical field of grinding equipment, and more specifically relates to a material taking device for a spiral vibration grinding machine. Background Art

[0002] When metal workpieces are processed, burrs are likely to form on the edges of the workpieces. The burrs on the workpiece surface must be further ground and polished with a vibration grinder to achieve better surface quality. Figure 1 The spiral vibration grinder a shown in the figure has a grinding process in which the workpiece and the abrasive stone are first placed together in the grinding tank b, and then, driven by the vibration device c, the abrasive stone and the workpiece vibrate together to generate friction, thereby grinding the surface of the workpiece. After that, when the workpiece is ground, the ground workpiece is manually taken from the abrasive stone and placed in the material box d, and finally, the material box d filled with workpieces is manually moved to the next process; the traditional material taking method is to manually bend over to take out the grinding stone and the workpiece at the same time, and then separate the grinding stone and the workpiece using a sieve. Since it is necessary to bend over frequently to take out the material and the grinding stone has a certain weight, it takes a lot of manpower and time, and there are problems of low material taking efficiency and high manual material taking intensity;

[0003] Therefore, there is an existing method of using a tooth rake to retrieve materials. Although it avoids the grinding stone being retrieved together, since the spacing between the teeth of the tooth rake and the height of the handle cannot be adjusted, when the user is tall or the depth of the grinding groove is large, it is necessary to manually bend down frequently to rake the workpiece. When the user is short or the depth of the grinding groove is small, it is inconvenient to rake the material by holding the handle. When raking a workpiece smaller than the spacing between the rake teeth, it will not be usable. In addition, since the tooth tips of the tooth rake are sharp, the workpiece is easily damaged when retrieving the material. In order to ensure the quality of the material, the material retrieving speed must be slowed down, which affects the overall material retrieving efficiency, resulting in a small scope of application, low material retrieving efficiency and high labor intensity. In addition, when placing the workpiece in the material box or moving the material box full of workpieces to the next process, due to the difference in height, it is necessary to frequently bend down or stand on tiptoe to adjust the material box, which affects the material retrieving efficiency. The overall problem of low material retrieving efficiency, high labor intensity and a small scope of application exists. Utility Model Content

The utility model has the advantages of high material retrieval efficiency, low labor intensity and wide application range.

[0027] Please refer to Figures 2 to 8 As shown, a material taking device for a spiral vibration grinding machine comprises a long handle, a short handle 1, a material box 2 and a trolley 3, a height adjustment assembly for adjusting the height of the material box 2 is installed on the trolley 3, a storage groove 4 for storing the short handle 1 is provided at the bottom of the long handle, the long handle is connected to a locking member for locking the short handle 1 in the storage groove 4, a main rake head 5 is connected to one side of the bottom of the long handle, and a plurality of main rake teeth 6 are fixedly connected to the main rake head 5, and an auxiliary rake head 7 is connected to one side of the bottom of the short handle 1; the auxiliary rake head 7 is arranged along its length. A plurality of auxiliary rake teeth are connected to the main rake head 5 for sliding, and the center distance between two adjacent auxiliary rake teeth is the same as the center distance between two adjacent main rake teeth 6. A plurality of grooves 8 for placing the auxiliary rake teeth are provided at the bottom of the main rake head 5, and the grooves 8 are located between two adjacent main rake teeth 6; the auxiliary rake teeth include left rake teeth 9 and right rake teeth 10 that fit each other, and the left rake teeth 9, the right rake teeth 10 and the main rake teeth 6 are all covered with rubber sleeves 11, and the auxiliary rake head 7 is equipped with a driving component for driving the left rake teeth 9 and the right rake teeth 10 to slide in two directions opposite to the length of the auxiliary rake head 7.

[0028] From the above description, it can be known that by setting a long handle, a main rake head 5, a short handle 1, an auxiliary rake head 7, a plurality of auxiliary rake teeth and a plurality of main rake teeth 6, when the staff is tall or the depth of the grinding groove is large, the long handle, the main rake head 5 and the main rake teeth 6 are used to avoid the staff from frequently bending over to rake the workpiece, thereby effectively improving the material retrieval speed. When the staff is short or the depth of the grinding groove is small, the short handle 1, the auxiliary rake head 7 and the auxiliary rake teeth are used to facilitate the staff to hold the handles to rake the workpiece, making the overall use easier, playing a role in improving the material retrieval efficiency, reducing the intensity of manual labor and increasing the overall scope of application; when the workpiece to be ground is small, through the storage groove 4, the locking piece and the groove 8, it is only necessary to place the top of the short handle 1 under the bottom of the long handle, and then align the short handle 1 with the bottom of the storage groove 4, and adjust the auxiliary rake teeth. To the bottom of the groove 8, then, push the short handle 1 upward into the storage groove 4 until the upper end surface of the auxiliary rake tooth abuts against the upper groove wall of the groove 8, and finally, use the locking piece to lock the short handle 1 in the storage groove 4, so that the spacing between the rake teeth can be initially adjusted; when the size of the grinding workpiece is smaller than the distance between the middle of the auxiliary rake teeth and the adjacent main rake teeth 6, because the auxiliary rake teeth are connected to the auxiliary rake head 7 by sliding along their length direction, through the left rake teeth 9, the right rake teeth 10 and the driving assembly, the driving assembly is used to push the left rake teeth 9 and the right rake teeth 10 to slide in opposite directions of the length of the auxiliary rake head 7 to preset positions, respectively, so that the spacing between the rake teeth can be adjusted twice, which can meet the needs of taking materials for workpieces of different specifications and sizes, and effectively improve the overall material taking speed, thereby further improving the material taking efficiency and increasing the overall scope of application;

[0029] The rubber sleeve 11 is used to prevent the tooth tip of the tooth rake from directly contacting and colliding with the workpiece and causing damage to the workpiece, thereby ensuring the quality of the workpiece and the overall material picking speed during material picking, and further improving the overall material picking efficiency and ensuring the material picking quality; through the height adjustment component and the material box 2, the height of the material box 2 is adjusted by the height adjustment component, so that the staff can quickly manually stack the workpieces taken out from the grinding groove in the material box 2, which makes the height of the material box 2 adjustable, and avoids the need for staff to frequently bend over or stand on tiptoe to take and put the workpieces into the material box 2 due to height differences, thereby affecting the material picking efficiency, and further improving the material picking efficiency, reducing labor intensity and increasing the scope of application; when the material box 2 is full and needs to be transported to the next process, the trolley 3 is used to quickly push the material box 2 filled with workpieces to the next process, avoiding frequent manual bending over or standing on tiptoe to carry the material box 2, and reducing manual labor intensity and improving the overall efficiency.

[0030] Furthermore, one end of the left rake tooth 9 and one end of the right rake tooth 10 are both connected to a slider 12, and a slide groove 13 is provided on one side of the auxiliary rake head 7 for the slider 12 to slide in a directional manner along the length direction of the auxiliary rake head 7, and a clearance groove 14 is provided in the auxiliary rake head 7 and communicates with the slide groove 13 at one side of the lower end; the driving assembly includes a first bolt 15, a connecting plate 16 located in the upper end of the clearance groove 14, a left connecting rod 17 and a right connecting rod 18, and the two ends of the left connecting rod 17 are respectively hinged to one end of the left rake tooth 9 and one side of the connecting plate 16, and the two ends of the right connecting rod 18 are respectively hinged to the right rake tooth 9. One end of the rake tooth 10 and one side of the connecting plate 16 are hinged; the left connecting rod 17 and the right connecting rod 18 are arranged in mirror symmetry with each other, and are each provided with a plurality of them. A through slot 19 is provided at the top of the auxiliary rake head 7, and the bottom of the first bolt 15 is fixedly connected to the connecting plate 16; the upper end of the first bolt 15 passes through the through slot 19 and is connected to a first butterfly nut 20 that abuts against the outside of the top of the auxiliary rake head 7. A group of vertical guide rods 21 are fixedly connected between the top and bottom of the make way slot 14, and the connecting plate 16 is provided with a group of guide holes 22 for the vertical guide rods 21 to pass through.

[0031] As can be seen from the above description, when the size of the grinding workpiece is smaller than the distance between the middle of the auxiliary rake tooth and the adjacent main rake tooth 6, and the distance between the left rake tooth 9 and the right rake tooth 10 needs to be adjusted, it is only necessary to rotate the first butterfly nut 20 in the direction away from the auxiliary rake head 7 until the first butterfly nut 20 leaves the first bolt 15, and then manually press the first bolt 15. Under the action of thrust and gravity, a part of the upper end of the first bolt 15 enters the through groove 19, driving the connecting plate 16 to descend, thereby driving the lower ends of the left connecting rod 17 and the right connecting rod 18 to open in two directions opposite to the length of the auxiliary rake head 7, thereby driving the left rake tooth 9 and the right rake tooth 10 on the slider 12. Slide along the length direction of the slide groove 13, and slide in two directions opposite to the length of the auxiliary rake head 7 until the left rake teeth 9 and the right rake teeth 10 slide to the preset position, and then rotate the first butterfly nut 20 on the upper end of the first bolt 15 again until the first butterfly nut 20 is against the top end surface outside the auxiliary rake head 7 again, thereby achieving the effect of adjusting the spacing between the left rake teeth 9 and the right rake teeth 10; in addition, the vertical guide rod 21 and the guide hole 22 are used to prevent the connecting plate 16 from shaking during the lifting process, which affects the stability of the spacing adjustment between the left rake teeth 9 and the right rake teeth 10, thereby ensuring the stability of the secondary adjustment of the rake tooth spacing.

[0032] Furthermore, the main rake teeth 6 are arranged in a cylindrical shape; the tip of the main rake teeth 6 is arranged in a conical shape, and is connected to a first protrusion 23 arranged in a spherical shape, the vertical cross-sections of the left rake teeth 9 and the right rake teeth 10 are arranged in a rectangular shape, and the four right-angled sides opposite to each other between the left rake teeth 9 and the right rake teeth 10 are arranged with arc portions 24; the tip of the left rake tooth 9 and the tip of the right rake tooth 10 are arranged in a conical shape, and are connected to a second protrusion 25 arranged in a spherical shape.

[0033] As can be seen from the above description, by means of the first raised portion 23, the column rake teeth are set to be cylindrical and the tip of the main rake teeth 6 is set to be conical, so that in the process of raking the workpiece, the problem of the main rake teeth 6 colliding with the workpiece and causing damage to the workpiece is further avoided. At the same time, it is avoided that the grinding stone is parked on the upper end surface of the main rake teeth 6 and manual sorting is required to affect the material picking speed, which plays a role in further protecting the quality of the material picked, improving the material picking efficiency and reducing labor intensity; by means of the arc portion 24 and the second raised portion 25, the problem of the auxiliary rake teeth colliding with the workpiece and causing damage to the workpiece is also further avoided, which plays a role in further protecting the quality of the material picked; in addition, the vertical cross-sections of the left rake teeth 9 and the right rake teeth 10 are both set to be rectangular instead of cylindrical, in order to prevent the formation of a large concave gap between the left rake teeth 9 and the right rake teeth 10, resulting in the grinding stone being stuck in the gap between the left rake teeth 9 and the right rake teeth 10, and requiring manual sorting, which plays a role in further ensuring the material picking efficiency and reducing labor intensity.

[0034] Furthermore, the long handle includes a fixed rod 26, a second bolt 27 and a telescopic rod 28 passing through both ends, the telescopic rod 28 is slidably sleeved on the outer peripheral surface of the fixed rod 26, and the main rake head 5 is fixedly connected to the bottom side of the fixed rod 26; the telescopic rod 28 is provided with a plurality of through holes 29 along its length; the top of the fixed rod 26 is provided with a first threaded hole 30 communicating with the through hole 29; one end of the second bolt 27 is connected with a nut, and the other end passes through the through hole 29 and the first threaded hole 30 in sequence, and is threadedly connected with a second butterfly nut 31, and the storage groove 4 is provided in the fixed rod 26.

[0035] From the above description, it can be seen that when the length of the long handle needs to be adjusted, it is only necessary to first rotate the second butterfly bolt until it is completely separated from the second bolt 27, and then screw the second bolt 27 out of the first threaded hole 30 and the through hole 29, and then slide the outer circumferential surface of the telescopic rod 28 and the fixed rod 26 upward or downward until the telescopic rod 28 moves to the height position that needs to be adjusted, and then screw the second bolt 27 through the through hole 29 again to be threadedly connected with the first threaded hole 30, and finally, screw the second butterfly bolt back to the other end of the second bolt 27 until the nut and the second butterfly nut 31 respectively abut against the opposite sides of the telescopic rod 28, so that the length of the long handle can be adjusted, thereby further increasing the overall scope of application.

[0036] Furthermore, the locking member includes a connecting sleeve 32, an external thread block portion 33 is provided at the bottom of the connecting sleeve 32, a first thread groove 34 communicating with the top of the storage groove 4 is opened on the inner side of the top of the fixing rod 26, the outer side surface of the external thread block portion 33 is threadedly connected to the first thread groove 34, a threaded column 35 is connected to the top of the short handle 1, a second thread groove 36 for threading the thread column 35 is opened in the middle of the bottom of the external thread block portion 33, a first threaded hole 30 is opened on the side of the connecting sleeve 32, and the sum of the lengths of the fixing rod 26 and the connecting sleeve 32 is greater than the length of the telescopic rod 28.

[0037] As can be seen from the above description, before the short handle 1 is pushed into the receiving groove 4 and the upper end surface of the auxiliary rake teeth abuts against the upper groove wall of the groove 8, the second bolt 27 is first screwed out from the first threaded hole 30 and the through hole 29, and then the telescopic rod 28 is slid downward until the bottom of the telescopic rod 28 contacts the top of the main rake head 5, and then the connecting sleeve 32 is screwed out from the top of the fixed rod 26, and then the short handle 1 is pushed into the receiving groove 1 until the upper end surface of the auxiliary rake teeth abuts against the upper groove wall of the groove 8, and then the connecting sleeve 32 is screwed into the top of the fixed rod 26 again, and the external thread block portion 33 is threadedly connected to the first thread groove 34, and the thread column 35 is threadedly connected to the second thread groove 36, so as to play the role of detachable connection between the short handle 1 and the fixed rod 26, thereby realizing the role of locking the short handle 1 in the receiving groove 4.

[0038] Furthermore, a third threaded groove 37 is formed at the top of the connecting sleeve 32 , and a threaded protective plug 38 is threadedly connected to the third threaded groove 37 for sealing the bottom of the storage groove 4 . A second threaded hole 39 is threadedly connected to the threaded protective plug 38 on the bottom side wall of the storage groove 4 .

[0039] From the above description, it can be seen that after taking the short handle 1 out of the storage groove 4, first unscrew the threaded anti-slip plug from the third threaded groove 37 at the top of the connecting sleeve 32, and then screw the threaded protection plug 38 into the second threaded hole 39, so as to achieve the function of sealing the bottom of the storage groove 4, thereby preventing the grinding stone from entering the storage groove 4 and affecting the normal use of the storage groove 4 during the process of raking the workpiece.

[0040] Furthermore, the height adjustment assembly includes a base plate 40, a support plate 41 on which the feed box 2 is placed, and a group of long screws 42. The base plate 40 is fixedly mounted on the trolley 3, and brackets 43 are fixedly connected on both sides of the base plate 40. The upper end and the bottom end of the long screw 42 are rotatably connected to the top end and the bottom end of the bracket 43 respectively. A rotating handle 44 is connected to the top end of the long screw 42, and a synchronous pulley transmission mechanism is connected between the lower ends of the long screw 42. Internal threaded rings 46 for the long screw 42 to thread through are fixedly connected on both sides of the support plate 41, and guide columns 47 are fixedly connected on the other two sides of the base plate 40, and guide sleeves 48 for the guide columns 47 to slide up and down are connected on the other two sides of the support plate 41.
