Description

Technical Field

[0001] The utility model relates to the technical field of hole expanding devices, in particular to a hole expanding device for an electronic clock housing. Background Technique

[0002] Electronic clocks are smaller and more convenient than traditional mechanical clocks, and most electronic clocks are composed of plastic housings spliced together. The shape of the housing is formed by injection molding. During injection molding, part of the slurry is likely to remain in the position of the hole to fill the hole. Therefore, a hole expanding device is needed to drill and expand the electronic housing. The housing is fixed by the hole expanding device, and then vertical rotation for hole expansion can ensure the stability of drilling and avoid the problem of unstable operation of holding the hole expanding device by hand.

[0003] However, the housing of the electronic clock is a circular structure or square plastic. At present, the fixing of the housing by the hole expanding device mainly uses the extrusion of the outer edges on both left and right sides, which is more suitable for square housings. The fixing force on the circular housing on both left and right sides is prone to sliding. Under the hole expanding rotation force, the circular housing is prone to extrusion deformation and break away from the fixing of the contact point, affecting the stability of fixing the circular housing. Moreover, when expanding the hole by lifting and moving, since the lifting is manually pushed and operated, the degree of lifting is not easy to control, and it is easy to lift too low during the expansion of the tapered thread hole, resulting in too large a hole expansion.

[0005] As a further optimization of this technical solution, the limiting rod is provided with a track plate, a rubber ring, a sliding block, and a fixing rod. The rubber ring fits on the outside of the fixing rod, the sliding block is embedded on the outside of the fixing rod, the sliding block is slidably matched with the inside of the track plate, the bottom of the sliding block is in extrusion activity with the hollow groove, the track plate is installed inside the hollow groove, the sliding block is in a square state, and there are ball bearings on both the upper and lower sides, and the ball bearings are slidably matched with the inside of the track plate.

[0006] As a further optimization of the technical solution, the fixed rod is provided with an elastic block, a hollow tube, a threaded rod, and a friction plate. The elastic block is attached to the lower end of the threaded rod, the friction plate is embedded at the lower end of the elastic block, the threaded rod is in threaded cooperation with the hollow tube, the rubber ring is attached to the outer side of the hollow tube, the sliding block is embedded on the outer side of the hollow tube, and the elastic block is made of rubber and has the characteristics of large elasticity and easy deformation.

[0007] As a further optimization of the technical solution, the first track plate is provided with a vertical plate, a blocking rod, a slide rail rod, and a spherical block. The blocking rod is movably engaged inside the slide rail rod. The slide rail rod is welded to the inner side of the vertical plate. The spherical block is slidably engaged with the inner side of the vertical plate. The spherical block is embedded on the side of the limiting plate. The side of the limiting plate is slidably engaged with the side of the slide rail rod. The blocking rod is located below the limiting plate.

[0008] As a further optimization of the technical solution, the blocking rod is provided with a pressure rod, a compression block, a stress rod, and a circular rod.

[0009] The electronic clock housing reaming device of the present utility model has the following advantages compared with the prior art:

[0010] 1. When fixing the outer shell in the present utility model, the fixed rod in the limiting rod is pushed, so that the sliding block translates in the track plate. Then, the rubber ring contacts and fits the side of the outer shell on the horizontal plate, and the threaded rod rotates and presses the elastic block. Thus, under the elastic force of the rubber ring, the outer shell is fixed and supported. The three limiting rods change their positions on the horizontal plate according to the shape of the outer shell, so that the limiting rods form an arc state to contact the circular outer shell. Furthermore, the periphery of the circular outer shell has an increased number of contact points, avoiding loosening due to opposite contact points of the circular outer shell and preventing unstable fixation due to relatively small contact points.

[0011] 2. In the present utility model, the circular rod drives the two pressure rods to rotate counterclockwise, so that the two pressure rods rotate to the left and right sides of the stress rod, and the compression block is squeezed and friction-fixed at the inner side of the slide rail rod. Thus, the middle stress rod blocks the lower end of the limiting plate, avoiding excessive sinking during conical reaming and causing over-reaming, and preventing the limiting plate from moving downward too much and affecting the reaming of the outer shell. Thus, the height of the blocking rod on the slide rail rod is adjusted. Furthermore, the supporting height of the blocking rod for the limiting plate is adjusted, so that when the limiting plate slides inside the vertical plate through the spherical block, it is limited, avoiding the reaming on the limiting plate being too deep and forming an overly large hole.

Specific Embodiments

[0020] To make the technical means, creative features, achieved objectives, and functions of the present utility model easy to understand, the preferred implementation schemes of the present utility model will be further elaborated below in combination with specific embodiments and the accompanying drawings. Embodiment

[0021] Please refer to Figures 1 - 6, the present utility model provides a reaming device for an electronic clock housing, and its structure includes a motor 1, a limiting plate 2, a drill bit 3, a first track plate 4, and a fixed table 5. The motor 1 is installed at the upper end of the limiting plate 2, the drill bit 3 is fixedly embedded at the lower end of the limiting plate 2, the drill bit 3 is installed at the lower end inside the motor 1, the limiting plate 2 is slidably engaged with the side surface of the first track plate 4, the first track plate 4 is fixedly embedded on the side surface of the fixed table 5, the drill bit 3 is located directly above the fixed table 5. The fixed table 5 is provided with a hollow groove 51, a horizontal plate 52, a flat plate 53, and a limiting rod 54. The limiting rod 54 is slidably engaged inside the hollow groove 51. The hollow groove 51 is installed on the inner side of the surface of the horizontal plate 52. The flat plate 53 is fixedly embedded at the upper end of the horizontal plate 52. The limiting rod 54 and the flat plate 53 are on the same horizontal line. The first track plate 4 is fixedly embedded on the side surface of the horizontal plate 52. The drill bit 3 is located directly above the horizontal plate 52. There are three limiting rods 54, which are arranged at intervals. Thus, the housing is placed on the surface of the horizontal plate 52. By sliding the limiting rod 54 inside the hollow groove 51, the two sides of the housing are in contact and fixed by the limiting rod 54 and the flat plate 53. Thus, the limiting plate 2 slides up and down inside the first track plate 4, and the drill bit 3 slides up and down under the control of the motor 1. Thus, the drill bit 3 reams the housing on the fixed table 5.

[0022] The limiting rod 54 is provided with a second track plate w1, a rubber ring w2, a sliding block w3, and a fixed rod w4. The rubber ring w2 is attached to the outer side of the fixed rod w4. The sliding block w3 is fixedly embedded on the outer side of the fixed rod w4. The sliding block w3 is slidably engaged with the inner side of the second track plate w1. The bottom of the sliding block w3 is in extrusion activity with the hollow groove 51. The second track plate w1 is installed inside the hollow groove 51. The sliding block w3 is in a square state, and there are ball bearings on the upper and lower sides, and the ball bearings are slidably engaged with the inner side of the second track plate w1. Thus, the fixed rod w4 is pushed, so that the sliding block w3 translates inside the second track plate w1. Furthermore, the rubber ring w2 contacts and fits with the side of the housing on the horizontal plate 52. Then, the fixed rod w4 is rotated, so that the bottom of the fixed rod w4 is in frictional extrusion with the hollow groove 51 to fix the position of the fixed rod w4. Thus, the housing is fixedly supported by the elastic force of the rubber ring w2.

[0023] The fixed rod w4 is provided with an elastic block w41, a hollow tube w42, a threaded rod w43, and a friction plate w44. The elastic block w41 is attached to the lower end of the threaded rod w43. The friction plate w44 is embedded and fixed at the lower end of the elastic block w41. The threaded rod w43 is in threaded fit with the hollow tube w42. The rubber ring w2 is attached to the outer side of the hollow tube w42. The sliding block w3 is embedded and fixed on the outer side of the hollow tube w42. The elastic block w41 is made of rubber and has the characteristics of large elasticity and easy deformation. Thus, the hollow tube w42 is limited by the sliding block w3, and then the threaded rod w43 is rotated to make it translate, so that the threaded rod w43 rotates and squeezes the elastic block w41. Furthermore, the friction plate w44 contacts the bottom of the hollow groove 51, and under the elastic force of the elastic block w41, the friction plate w44 is squeezed and fixed to the bottom of the hollow groove 51.

[0024] The first track plate 4 is provided with a vertical plate 41, a blocking rod 42, a slide rail rod 43, and a spherical block 44. The blocking rod 42 is movably fitted inside the slide rail rod 43. The slide rail rod 43 is welded to the inner side of the vertical plate 41. The spherical block 44 is slidably fitted with the inner side of the vertical plate 41. The spherical block 44 is embedded and fixed on the side surface of the limiting plate 2. The side surface of the limiting plate 2 is slidably fitted with the side surface of the slide rail rod 43. The blocking rod 42 is located below the limiting plate 2. There are three spherical blocks 44, which are arranged and distributed. The slide rail rod 43 is in a vertical state. Thus, the height of the blocking rod 42 on the slide rail rod 43 is adjusted. Furthermore, the supporting height of the limiting plate 2 by the blocking rod 42 is adjusted, so that when the limiting plate 2 slides inside the vertical plate 41 through the spherical block 44, it is limited, and to prevent the reaming hole on the limiting plate 2 from being too deep to form an overly large hole.

[0025] The blocking rod 42 is provided with a pressure rod t1, a compression block t2, a stress rod t3, and a circular rod t4. The stress rod t3 is embedded and fixed inside the compression block t2. The pressure rod t1 is located inside the compression block t2. The pressure rod t1 is embedded and fixed inside the circular rod t4. The compression block t2 is movably fitted inside the slide rail rod 43. The compression block t2 is made of rubber and has the characteristics of deformable movement. There are rods inclined at 60 degrees on both sides of the stress rod t3, which have a blocking effect. Thus, the circular rod t4 drives the two pressure rods t1 to rotate counterclockwise, so that the two pressure rods t1 rotate to the left and right sides of the stress rod t3. Furthermore, the compression block t2 is compressed, so that the compression block t2 is squeezed and rubbed against the inner side of the slide rail rod 43. Thus, the middle stress rod t3 blocks the lower end of the limiting plate 2, preventing the reaming hole from sinking too deep during conical reaming to cause an overly large reaming hole, and preventing the limiting plate 2 from moving downward too much and affecting the reaming of the outer shell.

[0026] Working principle: In this utility model, the outer shell is placed on the surface of the horizontal plate 52. By sliding the limiting rod 54 in the hollow groove 51, both sides of the outer shell are fixed in contact with the flat plate 53 by the limiting rod 54, so that the limiting plate 2 slides up and down in cooperation with the inner side of the first track plate 4, and the drill bit 3 slides up and down under the control of the motor 1. Thus, the drill bit 3 enlarges the hole of the outer shell on the fixing table 5. When fixing the outer shell, the fixing rod w4 in the limiting rod 54 is pushed, so that the sliding block w3 translates in the second track plate w1, and then the rubber ring w2 contacts and fits with the side of the outer shell on the horizontal plate 52. Then, the threaded rod w43 in the fixing rod w4 is rotated. Under the threaded rotation of the hollow tube w42, the threaded rod w43 rotates downward, so that the threaded rod w43 rotates and presses the elastic block w41. Then, the friction plate w44 contacts the bottom of the hollow groove 51. Under the elastic force of the elastic block w41, the friction plate w44 is pressed and fixed with the bottom of the hollow groove 51. Thus, the bottom of the fixing rod w4 is frictionally pressed against the hollow groove 51, so as to fixedly support the outer shell under the elastic force of the rubber ring w2. The three limiting rods 54 change their positions on the horizontal plate 52 according to the shape of the outer shell, so that the limiting rods 54 form an arc state to contact the circular outer shell, thereby increasing the contact points on the periphery of the circular outer shell, avoiding looseness due to opposite contact points of the circular outer shell, and preventing unstable fixation due to relatively small contact points.

[0027] In this utility model, manually move the position of the blocking rod 42 in the sliding rail rod 43 on the outside, and then rotate the circular rod t4 to drive the two pressure rods t1 to rotate counterclockwise, so that the two pressure rods t1 rotate to the left and right sides of the stress rod t3, and then compress the compression block t2, so that the compression block t2 is squeezed and rubbed against the inner side of the sliding rail rod 43. Thus, the middle stress rod t3 blocks the lower end of the limiting plate 2, avoiding excessive sinking during conical hole enlargement, preventing the limiting plate 2 from moving downward too much and affecting the hole enlargement of the outer shell. Thus, adjust the height of the blocking rod 42 on the sliding rail rod 43, and then adjust the supporting height of the blocking rod 42 for the limiting plate 2, so that when the limiting plate 2 slides inside the vertical plate 41 through the ball block 44, it is limited, avoiding the hole enlargement on the limiting plate 2 being too deep to form an overly large hole.
