Description

Technical Field

[0001] The present invention relates to the technical field of slide equipment, and in particular to an embedded slide with a ball rolling structure. Background Art

[0002] Electric slides, also known as single-axis manipulators, linear modules, and linear actuators, are actuators driven by servo or stepper motors and are essential motion actuators in automated equipment. Linear slides, serving as the fundamental guide element of transmission components, are mechanical structures capable of providing linear motion and can be used in either horizontal or vertical configurations.

[0003] The patent document with application number 202022548876.3 discloses an embedded slide, including a base, a movable seat, a screw rod, and a transmission mechanism. The base is provided with a mounting groove along its length direction, and a side plate is fixedly installed at one end of the base. The transmission mechanism is fixedly installed at the other end of the base. A dustproof plate is provided between the side plate and the transmission mechanism. An oil channel is provided at one end of the movable seat. By designing the oil channel, the contact surface between the movable seat and the screw rod can be lubricated to avoid excessive friction, reduce the degree of surface wear of the screw rod and the movable seat, and effectively extend its service life. At the same time, an accommodating cavity is formed between the base, the side plate, the transmission seat and the dustproof plate. The movable seat can move in the cavity, which limits the moving space of the movable seat, improves the stability of the movable seat during the transmission process, and prevents it from offsetting.

[0004] However, during operation, the slide has no additional limiting measures when moving. When in use, it is very easy for the slide to deviate due to transmission, which affects the stability of movement. The stability of its sliding action directly affects the accuracy of product and processing dimensions. Summary of the Invention

[0005] The purpose of the present invention is to address the problem in the background technology that the slide connecting seat has no additional limiting measures when moving, which makes it very easy for the slide to deviate due to transmission during use, thereby affecting the stability of movement. An embedded slide with a ball rolling structure is proposed.

[0006] The technical solution of the present invention is: an embedded slide with a ball rolling structure, comprising a slide body, a slide seat connecting seat arranged in the slide body, and a driving device installed on the outside of the slide body for driving the slide seat connecting seat to move, the slide seat connecting seat is connected to the slide via a mounting frame, and is characterized in that: a ball support seat is symmetrically fixed to the bottom side of the interior of the slide body, and a ball locking mechanism for quickly locking the slide seat connecting seat is provided between the ball support seat and the slide seat connecting seat;

[0007] The ball locking mechanism includes a fixing seat fixed to the inner wall of the slide body and a mounting slot provided on the slide connecting seat. An electromagnetic chuck A is provided on the fixing seat, and a limit shell is provided on the outer side of the electromagnetic chuck A.

[0010] The two limiting blocks face the limiting shell and the connecting shell respectively.

[0011] Preferably, the bottoms of the ball support seat and the sliding seat connecting seat are both embedded with ball grooves, and the balls are located between the ball support seat and the ball grooves of the sliding seat connecting seat;

[0012] The sliding seat connecting seat and the ball support seat are provided with slots for the sliding rod to move horizontally.

[0033] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] like Figure 1-5As shown, the present invention proposes an embedded slide with a ball rolling structure, including a slide body 300, a slide seat connecting seat 310 arranged in the slide body 300, and a driving device 100 installed on the outside of the slide body 300 for driving the slide seat connecting seat 310 to move. The slide seat connecting seat 310 is connected to the slide 200 through a mounting frame. A ball support seat 500 is symmetrically fixed to the bottom side of the slide body 300. A ball locking mechanism 400 is provided between the ball support seat 500 and the slide seat connecting seat 310 for quickly locking the slide seat connecting seat 310.

[0036] The ball locking mechanism 400 includes a fixing seat 410 fixed to the inner wall of the slide body 300 and a mounting slot provided on the slide connecting seat 310. An electromagnetic chuck A430 is provided on the fixing seat 410, and a limit housing 420 is provided outside the electromagnetic chuck A430.

[0037] An electromagnetic chuck B470 is provided in the mounting groove, and a connecting shell 480 is fixed to the outside of the electromagnetic chuck B470;

[0038] It also includes a plurality of balls 440 rollingly mounted on the bottom of the slide connector 310, a slide rod 460 is laterally inserted into the middle of each ball 440, and a limit block 450 is fixed at both ends of the slide rod 460;

[0039] The two limiting blocks 450 face the limiting housing 420 and the connecting housing 480 respectively.

[0040] Ball grooves are embedded in the bottom of the ball support seat 500 and the sliding seat connecting seat 310, and the ball 440 is located between the ball grooves of the ball support seat 500 and the sliding seat connecting seat 310; this prevents the ball 440 from escaping from between the sliding seat connecting seat 310 and the ball support seat 500, allowing it to roll stably on the ball support seat 500.

[0041] Slots for the horizontal movement of the sliding rod 460 are reserved on the sliding seat connecting seat 310 and the ball support seat 500.

[0042] The surfaces of the limiting shell 420 , the connecting shell 480 and the limiting block 450 are all provided with uniformly distributed limiting protrusions 490 .

[0043] The limiting protrusion 490 is a polygonal pyramid or an irregular protrusion. Figure 5 The arrangement of the polygonal pyramids is schematically shown in FIG.

[0044] The limit block 450 is made of a magnetic material that can be magnetically connected to the electromagnetic chuck B470 after being powered. When the fixing base 410 or the connecting shell 480 is powered, the sliding rod 460 can be moved horizontally under the action of the magnetic force.

[0045] The slide body 300 is provided with a through groove and a guide groove. The middle part of the mounting frame is slidably mounted in the through groove. The mounting frame is provided with a guide protrusion which is mounted in the guide groove and matches the shape of the guide groove.

[0046] In this embodiment, the slide rod 460 is cylindrical. During the movement of the slide connector 310, the fixed base 410 and the electromagnetic chuck B470 are simultaneously powered or unpowered, and the slide rod 460 and the ball bearing 440 maintain relative rotation, thereby preventing the limit block 450 from rotating and ensuring the braking effect when the limit block 450 contacts the limit housing 420.

[0047] The electromagnetic chuck B470, the connecting shell 480 and the driving device 100 are all electrically connected to an external power source and an external controller.

[0048] A cylindrical groove is formed in the middle of the ball bearing 440 , and an annular flange located in the cylindrical groove is fixed to the outer edge of the slide rod 460 , and a spring sleeved on the slide rod 460 is provided between the annular flanges.

[0049] The working principle of the embedded slide with ball rolling structure based on embodiment 1 is as follows: the driving device 100 drives the slide connecting seat 310 to move, and during the movement, the ball 440 is always located between the ball support seat 500 and the slide connecting seat 310. When the slide connecting seat 310 stops moving, that is, the driving device 100 stops working, the electromagnetic suction cup A430 is powered on to generate magnetic force, so that the limit block 450 on the left side overcomes the elastic force of the spring and contacts the limit shell 420. The protrusions on its surface quickly engage, increasing the friction force when the slide connecting seat 310 moves, thereby quickly locking the slide connecting seat 310 to prevent it from moving, thereby solving the problem that the slide connecting seat 310 has no additional limiting measures when moving, and is easily deviated due to transmission during use, affecting the stability of movement. When it needs to continue moving, the electromagnetic suction cup B470 is powered on and the elastic force of the spring can make the slide rod 460 quickly reset.

[0050] Example 2

[0051] like Figure 1-5 As shown, the present invention proposes an embedded slide with a ball rolling structure, including a slide body 300, a slide seat connecting seat 310 arranged in the slide body 300, and a driving device 100 installed on the outside of the slide body 300 for driving the slide seat connecting seat 310 to move. The slide seat connecting seat 310 is connected to the slide 200 through a mounting frame. A ball support seat 500 is symmetrically fixed to the bottom side of the slide body 300. A ball locking mechanism 400 is provided between the ball support seat 500 and the slide seat connecting seat 310 for quickly locking the slide seat connecting seat 310.

[0052] The ball locking mechanism 400 includes a fixing seat 410 fixed to the inner wall of the slide body 300 and a mounting slot provided on the slide connecting seat 310. An electromagnetic chuck A430 is provided on the fixing seat 410, and a limit housing 420 is provided outside the electromagnetic chuck A430.

[0053] An electromagnetic chuck B470 is provided in the mounting groove, and a connecting shell 480 is fixed to the outside of the electromagnetic chuck B470;

[0054] It also includes a plurality of balls 440 rollingly mounted on the bottom of the slide connector 310, a slide rod 460 is laterally inserted into the middle of each ball 440, and a limit block 450 is fixed at both ends of the slide rod 460;

[0055] The two limiting blocks 450 face the limiting housing 420 and the connecting housing 480 respectively.

[0056] The bottom of the ball support seat 500 and the sliding seat connecting seat 310 are both embedded with ball grooves, and the ball 440 is located between the ball grooves of the ball support seat 500 and the sliding seat connecting seat 310;

[0057] Slots for the horizontal movement of the sliding rod 460 are reserved on the sliding seat connecting seat 310 and the ball support seat 500.

[0058] The surfaces of the limiting shell 420 , the connecting shell 480 and the limiting block 450 are all provided with uniformly distributed limiting protrusions 490 .

[0059] The limiting protrusion 490 is a polygonal pyramid or an irregular protrusion.

[0060] The limit block 450 is made of a magnetic material that can be magnetically connected to the electromagnetic chuck B470 after being powered on.

[0061] The slide body 300 is provided with a through groove and a guide groove. The middle part of the mounting frame is slidably mounted in the through groove. The mounting frame is provided with a guide protrusion which is mounted in the guide groove and matches the shape of the guide groove.

[0062] In this embodiment, the sliding rod 460 is in the shape of a polygonal column.

[0063] By utilizing the arrangement of the polygonal columns, when the ball 440 rolls, the slide bar 460 and the limit block 450 rotate simultaneously.

[0064] The electromagnetic chuck B470, the connecting shell 480 and the driving device 100 are all electrically connected to an external power source and an external controller.

[0065] A cylindrical groove is formed in the middle of the ball bearing 440 , and an annular flange located in the cylindrical groove is fixed to the outer edge of the slide rod 460 , and a spring sleeved on the slide rod 460 is provided between the annular flanges.

[0066] The working principle is as follows: the driving device 100 drives the sliding seat connecting seat 310 to move. During the movement, the ball 440 is always located between the ball support seat 500 and the sliding seat connecting seat 310 and rolls. When the ball 440 rolls, the slide rod 460 and the limit block 450 rotate at the same time. When the sliding seat connecting seat 310 stops moving, the driving device 100 stops working. When the electromagnetic suction cup A430 is powered on, magnetic force is generated, so that the limit block 450 on the left overcomes the elastic force of the spring and contacts the limit shell 420. The protrusions on its surface are directly or indirectly engaged, which increases the friction force of the sliding seat connecting seat 310 when it moves, thereby quickly locking the sliding seat connecting seat 310 to prevent it from moving, thereby solving the problem that the sliding seat connecting seat 310 has no additional limiting measures when moving, and it is very easy to be offset due to transmission during use, which affects the stability of movement.
