Description

Technical Field

[0001] The utility model relates to the field of key duplicating machine accessories, and more specifically, to a key processing fixture with adjustable angle. Background Art

[0002] A key machine is a piece of mechanical equipment specially used for producing and processing keys. It can produce keys of different materials, sizes and shapes according to demand. It includes vertical key machines, and key machine fixtures are special equipment used for key duplication machines. Their main function is to fix the key prototype when duplicating keys, so as to facilitate the accurate cutting of new keys.

[0003] The existing fixture clamps the key blank by sliding two sliders horizontally. The slider base is fixed and the angle cannot be adjusted. It can only process holes and slots perpendicular to the key, but cannot process key holes with a certain angle and angled tooth shapes, so it is less practical.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a key processing fixture with adjustable angle. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a key processing fixture with adjustable angle.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an angle-adjustable key processing fixture, comprising a main body connected to supporting components at both ends, a screw is arranged on the main body, a left clamp block and a right clamp block are rotatably connected to the smooth rod portion of the screw, the left clamp block is connected to the right clamp block through a maintaining component, the right clamp block can move linearly relative to the left clamp block through the maintaining component, the central components of the left clamp block and the right clamp block are both provided with through holes for the smooth rod portion to pass through, a tightening wrench is threadedly connected to the threaded rod portion of the screw, the distance between the left clamp block and the right clamp block can be shortened by rotating the tightening wrench, and at the same time, the left clamp block is pressed against the surface of the main body to fix the front and rear angles of the clamping, and a stopper is fixedly connected to the end of the screw.

[0007] Preferably, a ball screw is installed on the surface of the main body, and the left clamping block is provided with a spherical groove matched with the ball screw for positioning the front and rear clamping angles.

[0008] Preferably, a spring is provided between the left clamping block and the right clamping block, and the spring is sleeved on the bare rod portion so as to allow rebound to occur between the left clamping block and the right clamping block.

[0009] Preferably, a scale indicator groove is provided on the contact surface between the left clamping block and the main body, corresponding to the scale provided in the middle part of the main body, so as to facilitate precise adjustment of the angle of the clamping component.

[0010] Preferably, a pressure bearing is provided on the contact surface between the tightening wrench and the part on the main body that contacts it, so that the rotation action is smoother and the rotation of the tightening wrench is prevented from being affected by too much resistance when it contacts other parts.

[0011] Preferably, the maintaining component is a positioning pin, and the right clamping block can move back and forth linearly along the positioning pin. The positioning pin has a simple structure and a low production cost.

[0012] Preferably, a set screw is installed behind the ball-end screw to prevent the ball-end screw from loosening and moving out of position.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model rotates the left clamp block and the right clamp block to make them rotate along the polished rod part, thereby adjusting the front and rear rotation angle of the clamping part. After the adjustment is completed, the left clamp block and the main body are rotated against the surface of the main body by tightening the wrench, so that the left clamp block and the main body are closely attached to each other. The front and rear rotation angle of the clamping is fixed by the friction force of the contact, so that the front and rear angles on the clamping parts of the clamp can be adjusted, so that key holes with a certain angle and tooth profiles with an angle can be processed. It is highly practical and can solve the problem that only holes and slots perpendicular to the key can be processed in the background technology;

[0015] 2. The utility model installs a ball screw on the surface of the main body, and the left clamping block is provided with a spherical groove matched with the ball screw, which is used to position the front and rear clamping angles. This first positioning makes it more convenient for the staff to perform the angle fixing operation;

[0016] 3. The utility model has a scale indicator groove on the contact surface between the left clamping block and the main body, which corresponds to the scale in the middle of the main body, making it easy for the staff to accurately adjust the clamping angle and greatly improving the key processing accuracy.

DETAILED DESCRIPTION

[0023] like Figure 1-4 As shown, the utility model provides an angle-adjustable key processing fixture, including a main body 1 connected to supporting components at both ends, a screw rod 2 is arranged on the main body 1, a left clamping block 3 and a right clamping block 4 are rotatably connected to a light rod portion 21 of the screw rod 2, the left clamping block 3 is connected to the right clamping block 4 through a maintaining component 5, and the right clamping block 4 can move linearly relative to the left clamping block 3 through the maintaining component 5, and the central components of the left clamping block 3 and the right clamping block 4 are both provided with through holes for the light rod portion 21 to pass through, a tightening wrench 6 is threadedly connected to the threaded rod portion 22 of the screw rod 2, and the distance between the left clamping block 3 and the right clamping block 4 can be shortened by rotating the tightening wrench 6, and at the same time, the left clamping block 3 is squeezed to the surface of the main body 1 to fix the front and rear angles of the clamping, and a stopper 23 is fixedly connected to the end of the screw rod 2.

[0024] When in use, the main body 1 is installed on the supporting component of the key machine. Two sets of this clamp need to be installed on the key machine, one of which is used to clamp the cloned key, and the other is used to clamp the processed key embryo. The clamp clamps the cloned key or the processed key embryo through the left clamp block 3 and the right clamp block 4 thereon (clamped by the clamping parts 13 on the left clamp block 3 and the right clamp block 4), and a spring 9 is arranged in the middle to control the rebound between the left and right clamp blocks 4 (the spring 9 is sleeved on the light rod part 21), and a maintaining component 5 is arranged between the two to keep the left clamp block 3 and the right clamp block 4 in the same straight line, (the maintaining component 5 is fixed on the left clamp block 3, and the right clamp block 4 can move along the maintaining component 5, and the maintaining component 5 can be used to maintain the left and right clamp blocks 4. The holding component 5 is preferably a positioning pin), and the left clamp block 3 and the right clamp block 4 can be rotated to rotate along the light rod portion 21, so as to adjust the front and rear rotation angle of the clamping part. After the adjustment is completed, the tightening wrench 6 is rotated against the surface of the main body 1 so that the left clamp block 3 and the main body 1 are pressed against each other, and the front and rear rotation angle of the clamping is fixed by the friction force of the contact. When the tightening wrench 6 is rotated in the opposite direction and no force is applied to the overall structure formed by the left clamp block 3 and the right clamp block 4 through the screw 2 (the left clamp block 3 is no longer pressed against the main body 1), the angle adjustment can continue. In this way, the front and rear angles on the clamping component can be adjusted, so that keyholes with a certain angle and angled tooth profiles can be processed.

[0025] Furthermore, a scale indicator groove 10 is provided on the contact surface between the left clamping block 3 and the main body 1, which corresponds to the scale 11 provided in the middle part of the main body 1 (the current setting angle is ±30°); when the clamping part (that is, the left clamping block 3 and the right clamping block 4 rotate along the light rod part 21), it is convenient to understand the front and rear rotation angle (to facilitate the staff to accurately adjust the clamping angle), a ball screw 7 is installed on the surface of the main body 1, and the left clamping block 3 is provided with a spherical groove 8 that matches the ball screw 7 for positioning the front and rear clamping angles (after positioning, the angle is fixed, which is more convenient for the staff to fix the angle), and it is best to install a stop screw behind the ball screw 7 to prevent the ball screw 7 from loosening and moving.

[0026] It should be noted that the ball screw 7 is composed of an outer shell, an inner spring and a steel ball. The steel ball will be pressed inside the outer shell when subjected to force. When there is no external force, it will be ejected by the force of the inner spring to cooperate with the spherical groove 8 for positioning, thereby preventing loosening before fixation. The ball screw 7 is the current existing technology.

[0027] Moreover, a pressure bearing 12 is provided on the contact surface between the tightening wrench 6 and the part on the main body 1 that contacts it. The pressure bearing 12 is located between the rotating shaft and the stationary supporting part. The friction is reduced by reducing the direct contact area, making the rotation action smoother, avoiding the tightening wrench 6 from being affected by too much resistance when it contacts other parts, and also avoiding it from driving the rotation of the connected parts it resists.

[0028] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
